Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the frame of the baler, having bearings ilat its forward end, in which is mounted speed reducing gearing mechanism of the ordinary type. Said speed reducing mechanism includes a drive shaft 12, one end of which is provided with a pinion 13 designed to drive a spur gear 14 mounted on a shaft 15, which is also rotatively mounted in the bearings 11. The shaft 15 is provided with a pair of pinion gears 16, which are in mesh with the spur gears 17. One of the gears 17 is mounted on a shaft 18, and the other on a shaft 19. The shafts 13 and 19 are in common alinement, and the gears 17 connected by a wrist pin The baler isprovided with side members 21, a top 22 and a bottom 23. The body of the baler is divided into a feed chamber 24, and a baling designed to operate in the feed chamber in the usual manner. Said plunger is operatively connected with the wrist pin 20 by means of a connecting rod 27. The sides of the baling chamber are provided with openings 23 and 29 for the `purpose. of permitting the tying'mechanism to be moved into and out of the feed chamber,

as hereinafterf described.

, The sides of the baling chamber are provided with horizontal slots 30 extending from the forward end of the baling chamber to its rear end, andin communication rat their forward ends with vertical'grooves 31. Said grooves 31 are formed in channel bars 32 secured to the sides of the baler and extending above the baler a considerable distance, as illustrated in Figure 2. The channels 32 are provided for the purpose of assisting in automatically handling the division blocks 33;.' the construction and operation of which are as follows: l

This part of my invention is best illustrated in Figure 30 is a side elevation'of `one* member- Figures 2) 81'9f 10 11 121 13 17 and 1'8- The di' lface of the plate 34 is provided with a block 35 having wire receiving grooves 36. The grooves 36 are spaced apart a distance equal to the spacing of the slots 30.

. The back ofthe plate 34 is provided with a vertical angle 37 secured adjacent to each end of the plate 34, said angles being provided with horizontal shafts 38 and 39, the shaft 39 being longer than the shaft 38. The outer ends of both of said shafts are designed to travel in the grooves 31 when the block isrmoved to position in the baler, and `to rtravel in slots 30 as the block is moved rearwardly through the baler. The ends of the baler a slight distance, as illustrated in Referring to Figure; 8 it will be seen that notches 40 arevprovided in the back flanges of the channels 32 to permit the ends of the shaft 38 to enterthe slots 30, and notches 41 are provided to permit the shaft 39 to enter the lower slots 30, the notches 41 being deeper than the notches 40, so that asthe division block is lowered into position, the ends of the Shaft 39 will not enter the notches 40. Spring actuated pawls 42 are provided which engage the sha-ft 39 and lock the division block against upward movey ment after it has been lowered into position.

After the block has been placed in position within the feed chamber, it is fed rearwardly by the movement of hay or other material being fed into the Daling chamber in the usual manner until a given block has reached the rear end of the baler. The block is then delivered to the up- -per endvof the groove-S81 by the following inechy anisrn:

Mounted transversely above the forward end ofthe baling chamber is a shaft 43 mounted in suitable bearings 44. Said shaft is provided at each end tif-ith sprockets 45.

Secured to each of the channel members 32 is a bracket 46 provided-with a sprocket 47. Each of the side members of the baler is provided with an upright post 48 in which is mounted a sprooket `49. A sprocket 50`ismounted in a suitable bracket 5l fixed to the rear end of the baler. An extension franie52 is provided which also carries sprockets 53 and 54.

Thefrarne 52 is provided with channels 55 which guider the ends of the shaft 39. The upper ends of the channels 55 terminate in forwardly and upwardly extending channel members 5,8, which have their forward ends curved to receive the sprockets 47, as illustrated in Figures 2 and 12. The lower ends of the channels 55 are in aline-nient with the rear ends of the slots 30.

rlhe frame member 52 and the uprights 48.

also carry channel members 57, having their loi-,verende in aline-ment with the upper ones of the slots The channels 57 are designed to receive the ends of the shafts 38. The forward ends of the channels 57 are mounted in such a manner as to deliver the 38 to the upper surface of the channel 56 in the manner illustrated in Figure 17. The shafts 38 are carriedv by a flange 58 secured to the inner edge of the channel 56, said iiange being ilustrated in Figures 9 and 13.

.Each set of sprockets 45, 47, 49, 50, 53 and 54 is designed to supporty a chain 59, said chain being provided with outwardly projecting lugs 6G, sa. lugs lo secured to the inner edge of the chain links, as illustrated inFigures 10 and 11.

plane slightly outside of the sides of the baling press in such a manner that as the shaft 38` reaches the rear end of the lower slot 3i), the said shaft will be engaged hy one of the lugs 60, as the chain 59 is operated in a clockwise direction, as shown in Figure 2. The shaft 39 will then travel in the grooves of the channels 55 and the shaft 38 of the given block will travel in the grooves of the clionnels 57. The ychains 59 move Said blocks through the channels.

The block nrst assumes the position A as illustrated in Figure Eloy dotted lines. The block is then moved to the position B, and thence to position C, and finally delivered to the grooves- Si of the channels 32, in the manner illustrated in .Figure i2. it will he seen that as the block travi-ils,freirA the position B to the position C it is inverted, so that the block is always fed vto the feed chamber with the grooves 36in the forward face of the block.

As the block is delivered to the slots 31, the shaft 39 restson spring retained arms 6l, with both of the shafts 38 and 39 within the slots 3l and the lower edge of the 'olock slightly above the upper side of the feed chamber, as illustrated in Figures 8 and 17. It will be seen by referring to Figures 2 and 17 that the sprockets 45 and 47 are so mounted that the chains 59 move downwardly and rearwardly from the sprockets 47 in such a manset of sprockets is mounted in a corninon tion 8l engages thev roller 79,

ner that the lugs 60- are caused todisengage the shaft39 as the said shaftis moved-into the slots 3l: Slots 62 are providedlin the rear edges of the channels 32 to permit the lugs 60 to enter said -channels as the lugspass over the sprockets 47.

0n account of the shaft 38 being shorter than f the shaft 39, the ends of the shaft 38 will not be continuously rotated and any. blocks being` moved to the deliveryend of the saler will be moved upwardly and then forwardly to slots 31,

In ractual operation three blocks are usedtwo of which are always in the paling chamber-while 'A the third is normally supported by the members 61.

the outer'end of the shaft i9 ,a nevell gear 63 fixed to said shaft. The outer `end. ofthe nhaftv 43 is provided with a bevel gear 64 in mesh h `a pinion krnounted on an inclined'shaft 51S, rotatively mounted in suitable hearings, The for" ward end of theV shaft is provided with a pinion 67 in mesh with the bevel gear 63; l

For forcing the blo into 'the `feed chamber l have slidably mounted in the upper end oi the grooves 3i a plunger 68, best illustrated in Figurel 8 and 17. Each end ofthe plunger 88 is provided with an upwardly-extending member 69, designed to travel in the grooves 31.-Pivotally secured to the inner edge of each of the members 69 isa link 70. The free ends of the links 70 are pivotally connected to upwardly and forwardly extending arms l'lirigidly secured 'to a rock shaft 72. Said shaft` 72 is mounted in suitable hearings carried by an upright 73,- on the sides of the baler. A rock arn174 is mounted on one end of said shaft 72, said arm being actuated by .a cam on the cam shaft 76, said shaftbeing vated position with the rol-ler 79 in engagement with the cam 75, as illustrated in Figure fl-il.-

- Itwill bessen that as the shaft 75 is rotated,

the cam V75 will be rotated unt? the arm 78 to he lowered, and in turn the free ends of the arms 71 loweredI which will cause the plungerV 68 to engage the upper edge of the lolock re-sting on the meinber 61, and the blockinoved downwardly against the resistance of said member 6l to position within baling chainber, with thek shaft 39 beneath. the pawls 42.

The plunger 68 is then. allowedto return to its normal position, after which a second-block may be moved plunger. l A

By this arrangement itw'll he. seen that I have provided a simple niechan which will automatically return the 1docks to an operative posiinto. position beneath said tion, where they may be held and retained, and

provided with nieans whereby the hlock will be automatically fed into 'position after the tying operationk has been completed, as hereina.fter described.

The cam shaft 76, together with other auto- For rotating the shaft 1 have mounted on -said blocks beinginverted during said movement.

matic timing mechanism is operated asV follows: Rotatively mounted beneath the frame 10 in suitable` bearings is a shaft 82, having one endy.provided with a gear 83 designed to mesh with a pinion 84 rotatively mounted on the shaft 19. The outer face of the pinion 84 has a hub 85 provided with a single notch 86 for receiving a lug 87 cf a clutch member 88, said clutch member being feathered to the shaft 19 as illustrated in Figure 3.

The clutch member 88 is actuated by means of 'a rock arm 89 having a fork 90 at one end. Pins 91 are carried by the forks 90 designed to `enter a groove 92 in the clutch 88.

A spring 93 is provided for normally applying an inward pressure to the clutch 88. The arm 89 is provided with flanges 94 for slidably receiving a trip block 95. The inner face of said block ,95 has an inclined portion 96 and aat portion The outer face of the spur gear 83 provides what I shall term a master cam, the periphery of said cam being provided with a lug 98 designed Ato engage the inclined portion 96 of the block 95,

to be disengaged from the notch 86. The clutch 30l nember is thrown into operative position by moving the tripv block 95 rearwardly, or to the left asshown in Figure 3.

This trip block is actuated by means of a rod 99, which has one end connected to the block 95, and the other end connected to a downwardly extending arm 100. The arm 100 is pivotally connected to a plate 101 carried by the frame of the baler, The free end of the arm 100 is de- ,.signed to be engaged by an angle 102 mounted on what I shall term a tension plate 103. Said arm 100 is yieldably supported forwardly by means of an expansible spring 104, so that as the plate 103 is moved rearwardly, after a bale .oi predetermined size has been formed, the

member 102 will then engage the lower end of the arm 100, swinging the said arm rearwardly and the block 95 rearwardly, thereby setting the cam 83 into operation.

. In this connection it will be seen that the pin-v ion 84 is mounted on the shaft which operates -the plunger 26. The pinion, therefore, is operated in unison with said plunger.

By providing a single lug 87 and notch 86, the

clutch 88 will be moved into operative position r nly at the time the plunger 26 is at its rearward position of movement.

If the block 95 should be tripped before the plunger has reached this position, the lug 87 will engage the face of the hub and travel an said face until the said hub has rotated to with the notch 86 in alinement with` position the lug 87, after which the said lug will enter the notch by the action of the'spring 93.v

The rear end of the baler is provided with the isual tension device 105, which consists of a rod 106 tired to the lower frame members of the baling chamber and slidably mounted in a bearing 107 secured to the central side plate 108. The upper end of the rod 106 is slidably mountd in a bearing 109 secured to the upper frame member. The upper end of each of the rods 106 is screw threaded and provided with nuts 110 and springs 111 whereby the bottom andy Vmounted. on pins 119.

baler is somewhat contracted. This provides means for offering comparatively high resistance to the material as it moves through the baler, which resistance may be varied by adjustment of the nuts 110, thereby providing means for varying the size, as well as the density, of the bale.

For throwing into operation the ymaster cam, and for taking up slack wires of the bale, after the wires have been tied in the .manner hereinafter described, I have provided what I shall term an auxiliary tension device.

Said auxiliary tension device consists of the plate 103 slidably mounted adjacent to each side of the baling chamber, said plates being slidably mounted on guide rails 112 secured to the bottom and top frame members. The lower edge of each of the plates is provided with bearings 113 slidably mounted on the lower rods 112, and slotted bearings 114 slidably mounted on the upper rods 112. The bearings 114 are slotted to permit the bottom and top members to be moved toward and from each other by the tension device 105.

The inner face of each of the plates 103 is provided with a pair of slidabl'y mounted dogs 115, best shown in Figure 19. The forward end of each of the plates is provided with inclined slots 116, slidably mounted on pins 117 supported in the plate 103. The rear ends of the dogs 115 are provided with curved slots 118 slidably The dogs are placed in a diverging manner as illustrated, with their apex ends provided with interlocking teeth 120, so that both of said dogsl may be operated in unison.

The forward ends of the dogs 115 are so mounted as to be engaged by the ends of the shafts 38 and 39, as the division block travels through the baling chamber, andl designed to disengage said shafts` and pass between them when said dogs have reached their rearward position of movement, relative to the plate 103.

-Pivotally secured to the back end of the upper dog 115 ie a pair of links 121, the outer one o! which is pivotally connected to the inner face of the plate 103, as illustrated in Figure 2, to form a toggle joint for locking the dogs 115 in their open position.

The plate 103 is provided with a slot 122 through which a pin 123 extends. One end of the pin 123 forms a pivot between the links 121, and the other end is connected to a vertical link 124. The lower end of the vertical link 124 is pivotally connected Aby a cam 125, which in turn is pivotally connected to the plate 103. The cam 125 has an inclined slot 126 for receiving a pin 127 carried bya slide bar 128. The bar 128 is slidably mounted adjacent to the outer surface of the plate 103.

The forward endof the bar 128 is pivotally connected to one arm of a bell crank 129 pivotally kmounted in the plate 103. The other arm of said bell crank is provided with a pin 130 slidably mounted in a groove 131 of the horizontal bar 132. The bar 132 is secured to a vertical slide bar 133. Said slide bar is mounted in bearings 134 secured to the sides of the baler. l

The lower end of the bar 133 is provided with i la lug 135 designed to rest on a cam 135 carried by the cam shaft 76. Rotatively mounted beneath the baler frame is a rock shaft 137, each end of which is provided with a bell crank lever 138. One arm of each lever138 is provided with ing the tier elements.

a link 139 piv'otauyconnected to the plate 103. The opposite arm of each bell Crank has a spring 140 so arranged that tension is applied to the plates 163 against rearward movement.

Thust will be seen that as the division blocks move rearwardly through the baling chambe;

the shafts 38 and-39 will engage the forward' edges of the dogs 115, as shown by dotted lines in Figure and any further rearward movement or" the division blocks will cause plates 103 to move rearwardly and tension to` be ap plied to the springs 140.

By this arrangement it will be` seen that a portion of the pressure applied to thev bale within the baling chamber-will be carried by the division blocks and resistance to its movement through the baler will be offered-by the dogs 115, the toggle joints 121, the plate 163, the bell cranks 188, the link 139 and the spring 146. VAs

the plates 163 move rearwardly, the pins 130 y oredeterniined rearward position of its movement. i f

1 will now describe the mechanism for placing the wires around the bales, and tying the rThe feed chamber of the baler, as before stated, is provided with openings 28 and 29 for receiv- Each of the openings is provided with a slidably mounted plate 141, said plates being slidably mounted in suitable grooves adjacent to the inner face of the side members 21, and adapted to open and close theopenings 28 and 29. Each of the platesv 141 is provided with a pin 142, shown in Figure 1,`designed to pass through the corresponding slots 36a ofthe side members 21.

Each of the pins 142 is mounted in a link 143, said links being connected to a-lever I144. "Said levers are pivotally connected to the main `frame 1.6, and have downwardly extending portions 145, each of which is provided with a roller 146 for operating in the cam groove 147 on the inner face of the cam plate 148 formed integral with the gear 83, see Figure 41.

The parts are so arranged that as the cam plate 148 is rotated, the lever 144 `will' be oscillated and the plates 141 moved to open orclosed positions. plates are moved to their closed positions while the baling operation takes place and moved to their open positions just before the tying mechanism is set into operation'. Y

The method of tying and the mechanism for performing the tying operation may be more easily described and understood by iirst describing in a general way the tying operation. Referenc is made to Figures45 to'49`inclusive. y

Mounted opposite the opening 29 is a movable member which I shall term the primary tier frame 149, and opposite the opening 28 is a tier .trame 156. Each tier frame is designed to move into and out of the feedrchamber throughsaid openings. Adjacent to each of the openings 28 and 29 is a wire kguide 151, for the purpose of guiding the wire as hereinafter rnade clear.

The secondary tier frame 150 is provided with a pair of wire clamps 152 adapted to clamp and hold one end of the wire 153, said wire extending` across the feed chamber and through suitable openings in the inner end of the primary tier kthe primary tierffrarne 149.

The material is then fed into the baling chamber and the` wire caused to move rearwardly with the division block, in the manner illustrated in Figures and 46, with the said wires 153 traveling in` the slots v30 of the baling chamber.

The frame members 149 and 150 are then moved inwardly to the position shown in Figure 49, wLi-h a portion of the free end'of the wire overlapping a portion of the opposite end of the wire. A second clamp member V154, which I shall term a twister clamp, rigidly holds ther loop portion of the' wire while Vthe clamp 152'holds the `free..

after which the tier frames are returned to their 'normal positions of movement, and the plates moved to their closed position as shown in Figure 46.

A moredetailed description of the mechanism' and operation of lows: i

Mounted laterally fromthe frame 10,and immediately below the opening 29, is a track 156, see Figures 4, 6 and 7,`on which is slidably mounted The track .156 `is provided with grooves 157 for receiving. downwardly extending anges 158 of the tier 4frame.

.the tier mechanism is as fol- Said frame comprises an upright plate 159 andia bottomplate 160.' Supported on the outer end VVof vthe plate 160 is an uprightY bearing 161`adapted to support a rotatively mounted shaft 162 on which is mounted a cam plate163;

@nerend of the shaft 162 is. provided With"a bevel gear 164 designed to mesh with the bevel .167 is rotatively mounted in asuitable bearing 168 carried by the main Vframe of the-baler. The

.inner endv of the` shaft 167 has a bevel gear169 in mesh with the bevel gear 170 mounted onthe upper end of a vertical shaft 171. Said shaft 5171 has a bevel gear 172 on its lower end, see Figure 1. Said. gear172 is in me'shfwith a bevel gear 173 mounted on the inner end oi 'a' sleeve 174 rotatively mounted on the shaft 76, which in turnis rotatively mounted kin a sleeve 175 mounted in suitable bearings 176. The forwardend of the sleeve 174 is provided with a pinion l''designed to coact with a mutilated gear .178 on. the cam plate 148, while the forward end of the shaft 76 is provided with a1 pinion 179 designed toicoact with a Ymutilated' gear 189 carried by they plate 148. The sleeve' 175 is providedV with a cam 181 designed to coact with a lug 182carried by the cam plate 148, while the sameisleeve 175 is provided with a cam 183 designed to coact with a lug 184 to cause thesaid sleeve 175fto be rocked, as hereinafter' more fully describe f i f The inner end ofthe sleeve 175 is provided with a segmental sprocket wheel 185,V see Figuresl 1, 4 and 15; "Saidhsprocket 185 is provided withz a chain 186 designed to operate on a sprocket pinion .187 carried byV a short shaft 188 and rotatively mounted in a suitable bearing beneath the track 156.-

. AThe shaft 188 is provided with a sprocket 189 vgear 165 carried by suitable bearings 166. The i designed to carry a sprocket chain 190 which passes transversely beneath the baling chamber and operates over a sprocket 191, carried by a suitable bracket 192, which in turn is supported by a laterally extending frame 193 from the opposite side of the baler. The primary tier framev 149 is provided with a downwardly extending arm 194, the lower end of which is attached to the lower run of the chain 190.

The segmental sprocket 185 is substantially four times the diameter of the sprocket 187, so that a rocking movement of the sleeve 175 through an angle of substantially 90 will impart one 1 revolution to the sprocket 189, and the run of the chain 190 moved a suiiicient distance to carry the inner end of the tier frame r149 substantially two-thirds the distance into the feed chamber to the position shown in Figure 49. f f

It will be seen that as the camplate 148 is rotated, the lug 184 willengage the cam 183, see Figure 41, and cause the cam 183 to be rotated in amanti-clockwise direction as shown in Figure 41, until the lug 148 passes `beneath the cam 183. This .will cause the cam 181 to be moved inwardly into the path of thelug 182, and the lower run of the chain 190 moved inwardly and with it the tier frame 149.

A further rotation ofthe cam 148 will cause the lug,182 to engage the cam 181-and the sleeve 175 rocked in the opposite direction, and in turn a reverse movement imparted to the Vchain 190 and the frame 149. A reverse movement of the sleeve 175 takes place on account of the cam 181 being supported from one side of the center of the plate 148, while the cam 183 is supported from-the opposite side of the center, as illustrated in Figure 1. f

The mechanism just described provides means vwhereby the primary frame 149 may be moved ary frame 150 into and out of the baling cham- Said secondary frame is provided with a ber. downwardly extending arm 195, -which makes connection with the upper run of the chain 190, as clearlyshown in Figures 1 and 20. The said secondary frame 150 is slidably mounted in the frame member 193.

It will further be seen that the gear 165 will be moved longitudinally of the shaft 167 as the frame member 149 is moved inwardly and outwardly, and that rotation may be imparted to the cam 163, while said frame member is being moved inwardly and outwardly.

'Ihe inner end of the frame member 149 is pro vided with a pair of inwardly projecting members 196, each of which is provided with a wire receiving opening 197. The front` face of each of the members 196 is provided with a roller 198, which serves as a wire guide, while the back face of each of the members 196 is provided with rearwardly extending brackets 199 having rollers 200 which' act as wire guides, the wire being threaded through the openings 197 and carried by the reels 201, hereinafter described in detail.

Secured vto the rear face ofthe inner end of the frame 149 is a. pair of brackets 202, each of which is provided with a central opening 203 in which is mounted a twisting mechanism, which is as follows, see Figures 26 to 32 inclusive, and

also Figure 7.

The center of the openings 203 are spaced apart, a distance equal to the spacing of the wires. The rear edges of the brackets 202 are provided with notches 204 through which the lthe hub within the opening 203, said plate beingv secured in position by suitable screws 208.

The hub 205 is provided with a slot 209 pro-` rjecting inwardly to the center of said hub for receiving wires to be twisted. Adjacent to one edge of the slot 209 is a clamp plate 210, having laterally projecting member 211 designed to be supported on a plate 212, by means of suitable' screws 213. The plate 212 is provided withslots 214 for receiving set screws 215 by means of which the plate 212 and the clamp plate 210 may be adjustably supported to increase or decrease the width of the slot 209 for adjusting the device to operate with wires of various diameters.

The opposite edge of the slot 209 is provided with a clamp plate 216, which has a laterally extending portion 217 detachably secured to a slide bar 218 mounted in a suitable groove 219 in the hub 205, whereby the clamp plate 216 may be moved toward or from the plate 210. The slide bar 218 is provided with a laterally eX- tending lug 220 designed to operate in a groove 221 in the plate 207. The plate 207 is provided with a pair of lugs 222, between which is pivotal- 1y mounted a lever 223 having a knob 224 on its lower end, and a link 225 pivoted to its upper end, said link being pivotally connected to the lug 220, as illustrated in Figures 27 and 28.

It will readily be seen that if the knob 224 is moved toward or from the plate 202, the bar 218 will be moved longitudinally in the slot 219, to cause the plateA 216 to move toward and from the plate 211, and cause the wires to be gripped as they enter the slot 209, after which the sprocket 205 may be rotated and the central portions of the overlapping wires twisted in the manner illustrated in Figure 49.

It will be seen by reference to Figures 27 and 28 that the parts are so arranged that when the member` 216 is moved inwardly toward the member 210, the pivot center between the members 223 and the link 225 will lie inside of the pivots of said lever and said link, thus forming a lock for retaining the clamp plates in a closed positiony during the twisting operation.

To insure against accidental unlocking, an annular flange 226 is provided, having a notch 227 for receiving the member 24 when the clamp plates are in anvopen position. The free end of the lever 223 is designed to ride over the edge of the flange 226, when the clamps are in a closed position, and during the time the rotation of the twisting member takes place.

The mechanism just ydescribed performs the function Vof the twisting mechanism 155 above referred to.

For rotating the sprockets 206 I have provided a chain 228 designed to operate over sprockets 229 on the members 202, in the manner illustrated in Figure 7. A pinion 230 is designed to engage the central portion of the iront run of said chain, said pinion being mounted on a horizontalshaft 231 in suitable bearings carried by `the upright plate 159. The outer end of the shaft the cam plate 163, see Figure 5.

Thus means is provided whereby the wires may llO be twisted after they have been properly placed in the slots 209. The detachable` clampingplates 210 and 216 provide means whereby renewal may be easily and quickly accomplished on account of excessive wear. f Adjustment is also provided for adapting the-device to operate with wires of different diameters, thereby insuring a perfect twist. This adjustment also insures against wear on the clamping plates.

-For operating the free ends of the levers'223, I have provided a roch shaft 234, see Figure 33, rotatively mounted in suitable bearings in the members 292. Said rock shaft provided with rock arms 235each of which has its free end `forked to receive the knob 224 of levers 222. The arms 235 are actuated by a rocking movement of the shaft 234 to swing the knob 224 inwardly or outwardly. rhe upper end of the shaft 284 is provided with a rock arin 236 connected to a link 237, see Figures 5 and 6, the outer end or which is pivotally connected to a bell crank lever 228 pivotally mounted on the plate 15,9.

The free end for the lever 226 is provided with a roller 239 designed to operate in a cam groove 240 in the plate 163. Ihus means is provided for opening and closing the clamping plates of the twisting mechanisinas the cam plate 63 is rotated.

To assist in guiding the wires into the twisting mechanism, and for retaining the free end ofthe wire, after it has been severed from the.A

bale, and for severing saidl wire, I have provided the following mechanism.

Pivotally mountedto the rear edge of each of the members 262 I have provided what I shall term a gate 241. vided with an inwardly Aextending arm 242, see Figure 7. Said arms 242 are pivotally connected to a link 243 having its cuter end carried by an upright link 244. free end of the link 243 is provided with a roller 245, designed to travel in a cam groove 246 in the plate ,163. Thus means is provided whereby the free ends of the gates 241 may be swung from the position shown in Figure 5 to the position shown in Figures 14 and 49, or vice versa.

The free end ci cach of the gates 241 is provided with a cutting and clamping mechanism illustrated in detail in Figures 21 to 25 inclusive. A head 247 is provided at its lower edge with a groove'or recess 248 and a notch 249 in its rear edge.

A slot 250 is provided'in which is slidably mounted a bar 251 having a tongue 252 on its lower end designed to be moved into and out of the'groove 248, and to travel between lugs 252 carried by the head 247, in such a manner thatwhen the wire 153 is moved into the notch 249 the bar 251 may be elevated and with it the lug 252, causing the wire to be gripped in the slot 248. v

Slidably mounted adjacent to the rear face of the head 247 is a cutterplate 254, also having a notch 255 for receiving the wire. The notches 249 and the notch 255 are in common alinement when the device is in its normal open position with the lug 252 at its lower limit of movement.

The'cutter plate 254 is provided with a laterally extending lug 256 designed to support a bolt 257 mounted on a spring 258. The vlower end of the bolt 257 is designed to support a lug 259 projecting outwardly from the slide bar 25. so that as the cutter bar 254 is elevated, the slide bar 251 andl the gripping lug v252 will alsobe Each of said gates is proyieldably elevated. Themember 252 is elevated a slight distance in advance of the cutting member 260, and the bar 254, so that the wire 153 isrmly gripped before the cutting operation takes place. That portion of the wire supported in the gripper is connected to the reel, while other portion of theiwire is carried by the twisted portion. Y l f f The nieansfor actuating the cutter bar 254 comprises a rock shaft 261 pivotally mounted to the outer edge of each of the gates 241, see Figure-s 5 and 6. One end of the roclzshaft is .provided with laterally extending portion v262 designed to enter an opening263 in the upper end oi the cutt r plate 254, while the other end of' the rock shaft k261 is provided with a forwardly extending arm 264 designed to travel in a slotted curved plate 265, which is slidably mounted '268 which have their ends connected to a coininon slide bar 269, slidably mounted adjacent to the inner face of the bar 243, having its free end carried by an upright link 270. Said slide bar 269 is provided with a roller 271 designed to .travel in a cam groove 272 of the plate 163.

I will now describe theconstruction of the secondary tier frame, which comprises a plate 273 slidably mounted in bearings 274 carried by the freine 198. The forward end of the plate 273 is provided with a hinge member forming what yI shall term a wire threader and designated by the numeral 275, see Figures 36, 37, 38 and 39.

The said threader is formed oi a plate provided with hinges 277, by which the threader is hinged to the plate 273. Said plate 275 is provided with horizontal grooves 278 and a vertical groove 279 connecting the outer ends of the grooves 278.

The groove 279 is provided with a pair of'clamping bars 280, each of which is provided at itsk outer end with a-laterally and inwardly extending portion 281, said portions being designed .to enter grooves 282 in the upper and lower edges or" the member 275. The members 281 are designedl to project above the upper and lower edges of the member 275, as illustrated in Figure 36, to form :wire receiving slots 283, andadapted toy receive the wire 153 in the manner hereinafter 'fully set forth, and to clamp and grip the wire as the bars 280 are moved inwardly toward each other, in the manner illustrated in Figure 29. The members 281,. and 282 forni the clamping devices 152 before referred to. Y

Pivotally mounted in each or the slots 272 is a lever 284, the outer ends of which are pivotally connected to the 'oars 288 and have their inner ends pivotally connected to the horizontal armsfof the bell crank levers 285. Said levers in turn are pivotally mounted on the inner end. of the plate 278 and have their other ends overlapping and pivotally mounted vto a pivot member 286 carriedy in unison and the lever 284 operated, which in,

turn will cause the bars 289 to be moved inwardly or outwardly to clamp or release the wires. The

pivotal connection between the members 284 and the members 235 is mounted in the pivot axis of the member 275, so that the clamp members 281 may be actuated when the bar 275 is in any of its swinging positions of movement.

A cover plate 239` is provided for the member 275, which retains the members 280 slidably in the groove 279 and covers the slots 278. The plate 289 is rigidly supported in position.

The outer face of the plate 289 is provided with a lug 290 connected to a link 291, which in turn is connected to a lug 292 carried by the slide bar 293, also mounted in the guides 288 outside of the slide bar 287.

Y It will be seen that if the bar 293 is moved longitudinally, the member 275 may be swung from the position in alinement with the frame 273,

as illustrated in Figure 37, to a.` position substantially at right angles tosaid frame, as illustrated in Figures 14 and 49.

For imparting movement to the slide bars 287 and 293, I have provided beneath the bottom of the baling chamber a pair of rock shafts 294 and 295, see Figures 4, 14, 15 and 20. The rock shaft 294 is provided with downwardly extending arm 296, having a cam roller 297 designed to operate in a cam groove 298 carried by the cam 299 supported on the cam shaft 76, so arranged that as said cam shaft 76 is rotated, rocking movement will be imparted to the shaft 294.

In a similar manner the shaft 295 is provided with an arm 300 having a roller 301 designed to operate in a cam groove 302 of a cam 303, also carried by the shaft 76.

Thev shaft 294 is provided with a pairof forwardly extending arms 304 designed to support a shaft 305 between them. Said shaft 305 is slidably mounted in the lower end of a vertical link 306, having its upper end pivotally connected to a bell crank lever 307, one arm of which is pivotally kconnected with the slide bar 287, see Figure 20.

By this arrangement it will be seen that a rocking movement of the shaft 294 will cause the link 336 to be elevated or lowered, and the bar 287 to be reciprocated longitudinally. 7

In a like manner the shaft 295 is provided with a pair of forwardly extending arms 308 connected by a rod 309 slidably mounted in the lower end of a link 310, which in turn has its upper' end pivotally connected to a bell crank 311, one arm of which is pivotally connected with the slide bar 293. Thus means is provided whereby the threader head may be swung about its vertical axis by rocking the shaft 295.

It will be seen that both the head 275 and the clamping device 152 may be actuated when the frame member 150 is in any of its sliding positions of movement, as the links 306 and 310 are free to slide on the shafts 305 and 309.

Both of the bell crank levers 307 and 311 are mounted on a single pivot pin 312 carried by the downwardly extending arm 195, both of said links being pivotally connected to a pair of horizontal links 313, which are also pivoted to the member 195. 310 against lateral movement due to frictional Contact between said links and the rock shaft as the frame member 150 is moved inwardly or outwardly.

I will now describe the wire guides 151 above referred to, see Figures 34, 35, 15 and 16.

Each of the 'saidwire guidesy comprises a frame The links `313 support the members 306 andV ally extending legs 320 spaced apart and each pro-f.

vided with an opening 321 in which is rotatively mounted a sleeve 322. The inner ends of the sleeves are provided with detachable collars 323 and the outer ends of the sleeves are provided with convex heads 324. Said sleeves are rota-fA tively mounted in the legs. Each of the sleeves has a slidable mounted pin 325. The inner ends of the pins are provided with grooves 326.

' A lever 327 is pivotally connected in the groove 326 of the upper pin 325, said lever in turnY being pivotally connected to the frame 314, which in turn is pivotally mounted to the slide rod 323, slidably mounted in the pivot member 316 and slidably mounted in the lower end of the pivot member 315. A spring 329 is provided forv yieldably supporting thev rod 328 at its lower limit of movement. The upper end of the lower pin 325 is pivotally connected with an arm 330 rigidly supported on the shaft 328.

By this arrangement it will be seen that if the rod 328 is elevated or lowered, the lower pin y325 will move in unison and in the same direction as the rod 323, while the upper pin 25 will be operated in the opposite direction, due to the fact that the lever 327 is pivotally mounted to the frame 314.

Detachably secured to each end of the frame 314 is a leg 331, each of which is provided with a sleeve 332 similar vto the sleeves 322, with the exception that the sleeves are arranged in opposite directions, so that the heads 324 are adjacent and spaced a slight distance apart. The last said sleeves are designed to receive the outer ends of the pins 325 when the bar 328 is at its lower limit of movement and thereby close the loop portion 333 formed by the inner and outer legs. Said loops are spaced apart a distance equal to the spacing of the wires, so that as the wire guides are swung on their pivots, they may be made to receive the Wires within the loops 333, when in one position of their movement, after which the said loops are closed and then by swinging the guides, the wires may be moved to another position for the purpose of delivering same to the twister and for guiding the wires.

The lower end of each of the members 316 is provided with a laterally extending arm 334, one of said arms extending forwardly, and the other one rearwardly, and are connected by means of a link 335, see Figure 15. The forwardly extending arm 334 is provided with a rearwardly extending portion 336 to which a link 337 is connected, said link being pivotally connected to a loop member 338 slidably mounted on the shaft 76 and adjacent to a cam 339. The loop 338 is provided with a cam roller 340 designed to be actuated by the cam 339, so that longitudinal movement will be imparted to the link 335, and rockingy movement imparted to the guide frames 314. Said frames are adapted to move into and out of the feed chamber.

Supported below the bottom of the baling chamber and adjacent to the shaft 294 is a rock shaft 341 having a downwardly extending arm 342 designed to operate` on a cam face 343 of the cam 299. Said shaft 341 is provided with an arm 344 which projects forwardly and'is designed to engage the lower end of the rod 328.

v vThus lmeans is provided whereby the rod 328 may be elevated and lowered, and the wire guide clampsopened and closed when the member 314 is in, an;T of its swinging positions of movement. In order to provide means whereby the wire may be fed at a comparatively uniform tension, I have provided the wire reels 201, each of which comprises a cylindrical member 345, having at one edge an outwardly projecting flange 346.-

One edge of the member 345 is detachably secured to the inner edge `of an annular member 347, by means of Y suitable fastening devices 348. The outer edge of the member 347 is provided with an inwardly extending flange portion 349 terminating in an outwardly extending flange 350. The outer face of the flange 346 is designed to support an annular member 351, having an inwardly extending flange 352 terminating in an outwardly extending flange 353 supported adjacent to the flange 350.

The member 351` is slidably mounted on bolts 354 and yieldably retained at its inner limit of movement by means of springs 355, so that the flanges 350 and 353 are yieldably supported adjacent to each other. The members 345, 350, and 352 are spaced apart to form a chamber for receiving the coil 356 of the wire 153. .The Wire 153 is designed to pass outwardly between the flanges 350 and 353. Each of the members 345 is hung on an arm 357 supported bythe main frame of the baler. See Figure 1.

Thus it will be seen that as the wire is pulled outwardly, the lower sides of the members 201 will be swung rearwardly and rotated on lthe members 357. The said members 201 always tend to assume a position with their most eccentric portions immediately below the arms 357, While the movement of the wire as it is fed to the tying member will have a tendency to swing said eccentric points rearwardly and to a somewhat elevated position, thereby providing yieldable means for taking up slack in the wire, due to the outward movement of the tier frames.

The practical operation of, my device is as follows:

Assuming that a bale has been completed, as shown in `Figure 45, and that the shafts 38 and 39 of the division block 35 have engaged the forward ends of the1dogs 115, and that the plate 103 Vhas been moved rearwardly until the angle 102 has engaged the lower end of the arm 100,

and that the said arm has been swung rearwardly,

causing the rod 99 to be'moved rearwardly, which in turnwill cause the trip plate 95 lto be Amoved rearwardly and to disengage the lug 98 of the cam 148, which in turn will cause the lug 87 to be forced against the outer face of the hub through the tension of the spring 93. As soon as the plunger 25 has moved to its rearward position ofv movement, the notch 36 will be in position to receivefthe lug 87, causing the gear wheel 84 to be rotated 'in unison with the shaft 19.

In actual operation the ratio vbetween the 'gears 83 and 84 is preferably three to one, so

that the crank shaft 19 will make three complete revolutions during the time thecam 148 makes one revolution.

v The arrangement of the mutilated gears k178 and 180, and the lugs 82 and 84 on the cam 148, is such that approximately four and one-half strokes of the plunger will take' place before the said mutilated gears or lugs move to position to operate on'their coacting members, it being understood that three revolutions of the crank 19 will produce six plunger strokes.

During the first stroke of the plunger after the cam is set into operation the feeding mechanism is stopped and the material from the feeder and baler severed, as fully described in my copending application on Feeder for baling presses, flied May 28, 1929, Serial Number 366,684.v `The next two inward strokesA are for the purpose of cleanng the feed chamber. i g Slightly after the beginning ofA the third-forward stroke, the mutilated gear 180 will engage the pinion 179, Figurel 1 showing thecam` 148 in last said position.r This will cause thecam shaft 76 to be rotated, and at the same time movement is imparted `to the lever 144, causing the plates 141 to be lwithdrawn from coveringy the openings 28 and 29.` i v The cam 339 will then impart inward movement to therod 337,v which will cause the guide members 151 to be moved inwardly into the feed chamber, to substantially the position shown by dotted lines in Figure 45, with loops 333. `The rock arm 300 is then actuated by the cam 302, causing the bar 293 to be moved inwardly and the threader head 275 rto be moved into alinement with the bar 273. The lug 184 will then engage the-cam 183, and cause the sleeve` 175 to be rocked andl the primary and secondary tier `frames to bemovedinto the feed chamber.

The threader head 275 is again kswung forwardly and back of the tier mechanism 155, as'illustrated in Figure 48. `The pins 325 of the guide device are then moved to their closed position, so that the wires 153 are locked in the loop portions 333. v f

The guide devices 151 are then moved-outward,- ly to swingthe wires 153 to a'parallel position with portions overlapping, as indicated in Figure 44, causing the overlapping portions'of the Wires to enter the ' grooves 204 and 209 of the twisting mechanism. The mutilated gear 178 at this time engages the piniongear 177,` causing the sleeve 1'74'to be rotated, and with it the cam '163 through the bevel gears-172, 173, 169, 170, 164 and 165, and their connecting shafts; The rotation of the cam 163 will first cause the bell crank 238 to be operated as' the said` cam is rotated `in an anti-clockwise direction, as illus- `trated in Figure 6, causing the link 237 to be operated andin turn the rock shaft 234, which will cause the clamping plates 210 and 216 to be closed through the lever mechanism 223, and the overlappingportions of the wires 153 to be gripped at their central portions. The mutilated gear 233 of the cam 163 is then brought into engagement with the pinion 232. causing the twister sprocket 206 to be rotated through the chain 228, the pinion 230 and the shaft 231. The free 'ends of the'overlapping wires are at this time rigidly Yclamped between the member 281 and the grooves 42800i the member 275', while the loop portion ofv the wire rests in the notches 249 carried by the head v247. The gates 241 at this time are swung to their forward position of movement, as illustrated in Figure 44, insuch a manner that the ends of the overlapping portions are rigidly held during the time the twister is in operation.

After the twisting operationV has taken place, the 'slide bar 269 is operated by the roller 271 travelingin the 'cam groove 272, causing the plates 265 to be lowered and the cutter bars 254 to be elevated, causing that portion of the wire lyingin the groove 249 of the head 247 to be gripped, and the twisted portion of the wire to be severed from the gripped portion.

VThe'roclr shaft 234 is again operated and the pressure released between the gripping plates 210 and 216. At the Sametime the members 281 are movedoutwardly to release the wire gripped thereby. The pins 32,5 are also withdrawn to open the loops 333. l It will then be seen that the tying operation of the wire has been completed, and the loop portion of the wire released from all of the gripping mechanism.

It will further be seen that a considerable space will remain between the twisted ends and the front endof the bale, which will result in a considerable' amount of slack in the wire.

At this period in the operation the cam 136 engages the lug 135,causi`ng the member 133 to be elevated, the bell crank 129 operated, the bar 128 moved longitudinally, and the link 124 lowered, causing the dogs 115 to be released from the shafts 38 and 39. This will then permit the bale to expand and the division block moved rearwardly, which will then draw theslack 4out of the newly tied wires, and the twisted ends-of the wires-to iirmly engage the forward end ofthe bale. This leaves the feed chamber back of the tier mechanism entirely free fromfany loose or slack wires.

' The forward movement of the plate 103 will cause the member 102 to disengage the arm 100 but the' clutch memberis still retained in its closed position due to the action of the spring 93.

The'link 243 is at this time operated by means oi' the roller 245 traveling in the groove 246, which will cause Vthe gates 241 to be swung rearwardly in a plane substantially parallel with the plate 149. The gripping mechanism of the head 247 still retains 'the lfree end of the( cut wire. The wires are then` drawn rearwardly in such a manner that they will be brought into alinement with the grooves or notches 283 of thel head 2'75, assuming the positionillustrated in Figure 33.

The rtier frames are then moved outwardly on account of the lug 182'engaging the cam 181 and reversing the movement of the chain 190.' This will cause the wires supported by thehead 247 56 to enter the notches 283, after which' the bars 280 are againmoved inwardly and the cutter plate 254 movedy downwardly, releasing the wire from the head 247, said wires being pulled out of the notches 249 and the tier frames returned l'to their outer limits of movement. The guidesV 151 are also returned to their normal positions of movement, as illustrated in Figure 14, with the wires projecting laterally across the feed chamber,

`which are at all times kept taut due to the swinging movement of the wire reels as above described. The cam at this time engages the roller 79 causing the arms 71 to be swung'downwardly and a new block to be pushed into position within the slots 31. vThe plates `141'are then moved rearwardly, causing the wires` to be'moved from the position illustrated in Figure 14, to position within the grooves 36 of the block 35.

The feeder is then sety into operation through mechanism'carried by the inner end of thecam shaft 82. 'Ihe lug 98' of the cam'148 will then engage the cam surface 96 of the member 95, causing the arm 89 to be swung outwardly and the lug 87 to be withdrawn from the notch 86, as the said lug 98 engages the face97, after which the mechanism is in its normal position ready to 'receive a new bale..

Thus it will be seenthat I have provided a baler having means whereby the division blocks will be automatically placed in position and willbe locked imposition against upward movement, clue to the action of the compressed hay against the block, and at the same time providing means for automatically returning the block to its forward position of movement, where it is held in position to be lowered when the tying operation has been completed. This mechanism is automatically controlled and operated.

It will further be seen that I have provided means for automatically placing wires around and tying or twisting the same, and in connection therewith means whereby the slack will be taken out of the wires after they have been twisted, so that slack wire is completely withdrawn from the feed chamber, where it will not interfere with the placing of the new'blockin position or become tangled on the various devices as the .bale is moved through the baler.

It will further be seen that the twisted portion of the tie comes midway between the sides of one end of the baler where the strain on the wire, and'its tendency to untwist, are the least.

It will further be seen that I have provided an improved auxiliary tension device which' may be used in connection with the ordinary tension'devise, which performs the double function of setting into and out of operation the various mechanisms for performing the feeding and tying operations, and at the same time providing means for taking up slack in the newly tied wires.

It will further be seen that I have provided an improved twisting mechanism which is adapted to be adjusted against wear, so that the wires are always firmly and positively gripped before the twisting operation takes place, and thereby insuring a complete twisted tie, and at the same time providing means for adjusting the device to wires of various diameters,v

Means is valso provided for taking up the slack vwire as itis fed to the tying mechanism,rand as it is drawn to position around the bales as they are being formed. K AI claim as my invention:
