Referring particularly to Figures 1, 2 and.

3, the embodiment of the machine selected for illustration is shown as base 1 indirectly through means of a plurality of beams 2. The receiving end of the machine isprovided with a number of spaced uprights 3, connected by means of horizontal braces 4. The receiving belts for receiving the articles or slungles as they are discharged by the machine performing the last operation on the same issupported within the vertical uprights 3 by means. of stationary end beams 5 having mounted thereon the end pulley 6 andhorizontal adjustable beams 7, the latter having mounted on their projecting end pulleys 8. The endless belts 9, forming the belt receiving circuit, passes over the pulleys 6 and 8 and is supported intermediate of the pulleys by the platform 10 which serve to support the weight of the'articles located on the belts. The belts after passing over pulis a sectional elevational view supported upon a leys 8 are directed over pulleys 11 journaled in the stationar bearin 12 in turn secured tov the a-djustab e beam? and thence passes over the stationary pulleys 13 mounted for rotation upon the forward uprights 3, from which the belt travels rearwardly around the rear pulley 6 eomplet-in the circuit. The forward pulleys 8 of the belt circuit are mounted upon adjustable supporting beams so that the machine can accommodate articles of various widths, and for this purpose the beams 7 are slotted at points 14 adjacent the uprights 3 and are adapted to be rigidly held in a justed position by means of the securing members 15. Rotatably mounted upon the intermediate beams 4 is a. shaft 16, Figure 7, having secured thereto pinions 17 adapted to mesh with they ratchet bar 18 secured to the beam 7. .The operating wheel 19 secured to the shaft 17 provides for manual rotation of the shaft and thus foradjustment of the position of the beams 7.

The bundles of shingles or similar articles 20 as they leave their forming machine are deposited upon the constantly rotating belts 9, which serve to deliver them to conveyer means, to be later described. For positively removing the bundles 20 from the belts as they reaeh'the discharge end of the belt circuit, pusher arms 21 are provided of crank formation and pivotally secured at their midportions to actuating arms 22 and at their upper end to fulcrumlevers 23. Referring to Figures 2 and 7,. the fulcrum levers 23 are shown as pivot-ally secured at 24 to adjustable depending supports 25. Rotatably mounted in the supporting members 25 is an operating shaft 26 having secured at its outer end a sprocket 27for accommodating the endless chain 28. Secured intermediate of shaft 27 is a pinion v29 having meshing engagement with gear 30 fixedly secured to shaft 31, also journaled in the members 25. To the outer ends of shaft 31 is secured cams 32 to which are pivoted as at 33, the operating arms 22. The fulcrumlevers 23 are provided with curved depending extensions '34 extending rearward from their pivot point 24, and having rollers 35 rotatably mount-ed Within their forked end adapted to have enbars 18 havingpinions 17 on shaft 16 mesh-' ing therewith.

of the conveyor.

From the receiving belt circuit the bundles 20 are discharged to sets of arms secured to an endless chain forming a vertically disposed conveyor. The conveyor clearly disclosed in Figures 1, 2 and 3 comprises a plurality of spaced endless chains 36 passing over sprockets 37 in turn secured to a rotatably mounted shaft 38 journaled in bearings 39, secured to the base 1 to form the lower end t the upper end the chains 36 pass over sprockets 41 secured to the rotatably mounted shaft 42, ournaled in bearings 43, in turn secured to the conveyor frame. Located on the endless chains 36 at intervals are a plurality of arms 44 having adjustable extensions 45 and secured to the endless chains by means of a specially constructed link. The links support the transverse bar 46, to the ends of which are secured rollers 47, the bar in turn having secured thereto the arms 44 by means of the securing nuts 48. They conveyor frame is composed of a plurality of right angle members suitably secured to the general. frame work of the machine and spaced to provide pairs of aligned channels, as shown in Figure 1, through which the rollers 47 are adapted to pass and thus the horizontal arms 46 are maintained rigid during their vertical movements.

The arms 44 are adapted to have intermittent movement imparted thereto by means of a pawl and ratchet arrangement, more pa'ticularly disclosed in Figures 8 and 9. Rotatably mounted on shaft 42 at one end is yoke 51 having formed integrally therewith a second yoke 52. Fixedly secured to shaft 42 by means of a key 53 is a ratchet 54, the same being disposed within the arms of yoke 51. The periphery of ratchet 54 is provided with a plurality of spaced notches 55 on its inner surface 56 and a plurality of spaced notches 57 on its outer surface 58. It is noted that the notches 55 are arranged in groups around the periphery of the ratchet, while notches 57 are single and are disposed adjacent the group, of notches 55. Rotatably mounted upon shaft 59 ournaled in yoke 51 are a plurality of pawls 60 and 61 adapted to engage surfaces 56 and 58 respectively and yieldingly pressed against said surfaces by the spring clips 62. To stud 63 journaled in the secondary yoke 52 is secured shaft 64 having pivotal connection at its other end to crank arm 65 secured to shaft 66, journalecl in bearing 67 in turn located upon the upper end of the forward uprights 8. To shaft 66 is secured the sprocke 6S accommodating the endless chain 69 which provides the necessary rotation for the shaft. Through the crank arm 65 and shaft 64 the yoke 51 will be given an oscillating movement upon shaft 42 and consequent rotation of the shaft will take place by reason of engagement of pawls 60 or 61 in their respective notches provided in the fixedly mounted ratchet wheel 54. To the angle member 70 forming part of the conveyor frame is secured a cam plate 71 having a cutaway face 72 to allow engagement of pawl 60 with the notches 55 to take place, and as it will be noted, having its remaining edge rounded as at 73 on a slightly greater radius than that of the ratchet wheel 54. As yoke 51 oscillates towards the left, as shown in Figure 8, pawl 60, having a width. such that it will slightly overlap the cam plate 71, will be lift-ed by means of the rounded surface 73 of the plate so that in this movement of the yoke the pawl 60 will not engage notches 55. However, as the yoke 51 oscillates towards the right the pawl 60 will engage the foremost notch 55 disposed, adjacent the vertical face 72 of the plate, since the pawl is freed by reason of this cutaway face. Any further movement towards the right of yoke 51 will cause rotation of the ratchet wheel and thus rotation of shaft 42 in a direction such that the arms 44, disposed adjacent the delivery end of the belt circuit, will have a lowering movement. It will be noted that pawl 6.1 has engagement at all times against face 58 and thus at the proper time oscillation towards the left of yoke 51, as shown in Figure 8, will allow pawl 61 to drop into notch 57 and upon movement of the yoke towards the right, the ratchet wheel 54 and thus shaft 42 will be given rotation, the extent of which will be equal to the oscillation of yoke 51. This rotation of shaft 42 will cause consequent lowering of arms 44 such that the particular set of arms 44, having the correct number of shingles deposited thereon, will be lowered away from the discharge end of the belt circuit and will deposit the stack of shingles or similar articles 75, containing the correct number, upon the roller conveyor comprising a plurality of spaced rollers 76 supported upon suitable uprights 77. It will be noted, Figure 1, that the-rollers are spaced such that they are located intermediate the arms 44 so that the arms in their movementpass through the roller conveyor depositing their bundle of shingles thereon.

The sets 0" arn'is 44, previously to being located adjacent the discharge end of the belt circuit to have deposited thereon the stacks of shingles 20, are adapted to receive a bottom board 7 6 upon which these shingles are deposited. Located adjacent the vertical con-- veyor and to the right thereof, as shown in Figure 3, is a magazine formed by a plurality of spaced uprights 79 for containing a sup ply of the boards 78. Forming the bottom of the magazine and supporting the boards contained therein is a delivery arm 80 integrally secured to the pusher arm 82, the latter operating in the slots 81. Movements towards he left of a m 80 carries with it a ice bottom board as the arm has pivotally secured to it the finger 83 resiliently urged into engagement with the bottom board by means of any resilient member. Upon return movement towards the right of the arm 80, the bottom board will come into engagement with the pivoted stop 84. The stop therefore causes discharging of the board upon the arms 44, while the arm 80 is again positioned under the boards in the containerready for another operation. 7 7

With the parts in position, as shown in Figure 3, it will be noted that a set of arms 44 are located directly adjacent the magazine in po sition to receive a bottom board while the next lower set inposition such that it has deposited thereon the stacks of shingles 20, while a. third set has just passed between the spaced roller-s76 depositing their bundle of shingles upon the rollers. Simultaneously with the parts assuming the above described position the delivery arm 80 and pusher arm 82 are reciprocated, by mechanism to be described, towards the left causing the former arm to deliver to the uppersct of arms 44 a bottom board, and the pusher arm to engage the bundle of shingles 75 resting on the roller 76 and push the same upon the rollers until they are located adjacent other mechanism for depositing upon the bundle a top board and instruction sheet, as will be presently described.

Asecond set of rollers 85, Figure 12, 1'0- tatably supported upon channel members 86 is provided to form a continuation of the roller'conveyor and upon which the bundle of shingles 7 5 are pushed by the arm 82 as described. As shown in Figure 4 the rollers are supported upon uprights 87 in turn supported upon one of the beams 2 and located adjacent uprights 88, which, in connection with members 89, uprights 90 and base 91, form a magazine for containing a plurality of top boards 92. Rotatably mounted in suitable bearings secured to the upright 88 at a point adjacent the base 91 is a shaft 93 having a knurled roller 94 located intermediate thereof and a sprocket 95 fixedly secured to one end. Associated with the knurled roller is a plane surface roller 96 mounted on shaft.

97 and journaled in resiliently mounted bearings 98. Through means of an endless chain 99 associated with sprocket 100 secured to shaft 101 the knurled roller is continuously rotated in a direction to cause positive move ment of a board towards the right upon the same being fed thereto. The feeding means, as shown in Figure 4, comprises a delivery arm 102 having secured at its forward end the pivoted finger 103, the finger having a raised catch adapted to engage the rear edge of the bottom board in the magazine, and as the arm 102 is reciprocated the same is presented between the rollers 96and 94. To arm 102 is pivotallysecured the fulcrum lever 104 pivoted at 105 to the upright 90 and having pivotally secured at its lower end an actuating arm 106. By means of the crank 107 secured to shaft 101, to which is pivotally con nected the actuating lever 106, arm 102 is given the desired reciprocating movement.

The bundle of shingles 75 are directed on to the rollers 85 between deflecting plates 108 and 109. Located intermediate of deflecting plate 109 are spaced plates 110 and 111, Figure 6, each provided with an aperture 112 of substantially the same size and in alignment with each other, the plates forming a chamber between which is adapted to be located an instruction sheet 114. The magazine and mechanism for containing and feeding the instruction sheets comprises uprights 115 upon which is supported spaced rectangular frames 116. Located upon the frames 116 is an oblique supporting member 117 having spaced side members 118 and having suitably secured upon its oblique surface a rearwardly extending base plate 119. Suitably secured to the side members 118 and adapted to form extensions of said members are up rights 120 which form supporting means for spaced horizontal rods 121 upon which are slidably mounted frames 112 to form the container proper for the instruction sheets. The back 123 of the container is adjustable with relation to thefront portions of the frames 122 and serves to horizontally urge the sheets into contact withthe front portions of the frame. Secured to the respective ends of the upper rod 121 are diagonal members 124 extending slightly beyond'the back 123 and connected by means of rod 125 having engagement with the back. Similar diagonal arms 126 are pivotally and resiliently connected to arms 124 at 127, the members 126 being connected at one end by the horizontal rod 128 which in turn has engagement with the back 123, and at their other end slidably connected by means of slotsl29 to the stationary pin 130 suitably mounted upon the uprights 120. The bottom plate 131 pivoted at 132 to the side members 118 completes the container, the plate being resiliently supported upon base 119 by means of the coil spring 133 incorporating the limit stop 134.

Rotatably mounted within the side u1elnbers 118 is shaft 135, having suitabl y secured thereto a plurality of feeding wheels 136 having on their periphery a plurality of angular teeth so that during rotation they will impart positive movement to the foremost sheet in the magazine described. The shaft 135 at its left hand end, as viewed in Figure 5, is provided with a bore for accommodating shaft 137rotatably mounted in the left hand side member 118. Thus, in connection with shaft 137 and shaft 135 the feeding wheels 136 are supported from the side members. Provided on shaft 137 is a ratchet wheel 138, while the pawl 139 operatively associated therewith is pivotally mounted on shaft 135 the arrangement allowing rotation of shaft 137 to be imparted to shaft 135 and thus the feeding wheels 136 only in a particular direction necessary to cause feeding of the instrucand positively feed the same tion sheets from the magazine to the aligned apertures 112. Continuous rotation is of course imparted to shaft 137, since the same has secured to its outer end pinion adapted to mesh with the ratchet teeth 141 provided in the upper surface of the slotted portion of mm 142. Shaft 143 rotatably mounted on the frames 116 imparts the necessary movement to arm 142 through means of the crank 144, the shaft being driven through means of sprocket 145 and the endless chain 146. The instruction sheets removed from the magazine by the feeding wheels 136 are directed between plates 110 and 111 to constantly rotating pressure rollers 147 suitably journaled within bearings 148 mounted on the uprights 115. The outer bearing 148 journaling the outer pressure roll is suitably apertured and located upon a plurality of projecting studs 149 upon which are mounted coil springs 150, the, springs thus being adapted to resiliently engage the outer hearing 148 resiliently urging the pressure roller journaled therein towards its companion roller. By means of sprocket 151 and end less chain 152 one of the pressure rollers is continuously rotated and thus the construction serves to receive the instruction sheets presented thereto by the feeding wheels 136 tov mechanism to be described. g The rectangular frames 116 are provided with transverse'guides 153 to form a channel for receiving, the plunger 154. The plunger is adapted to be reciprocated and for the purpose is locateddirectly in align ment with apertures 112 formed in the plates 110 and 111 respectively, the movement 0 the plunger towards the left functioningto carry with it the instruction sheet and thus locating the same upon the bundle of shingles 75 prior to thereon. For actuating the plunger 154 same has pivotally secured thereto an arm 155 to which is pivotally secured the lever 156 having connection to the rear upright 115, a stationary arm 157 rigidly secured to the rear upright 115 provides a connection v for the coil spring'158 which at its other end of power,

is connected to the arm 155 and lever 156 at the pivot. As shown inFigure 1, shaft 160 journaled in bearings 161 secured to the rear uprights 115 has located intermediate thereof the oblong shaped cam 162 adapted to have contacting engagement with the pivotally mounted lever 156. Rotation of the shaft 160 is accomplished by the endless chain 163 having connection to a suitable source the shaft in turn being provided with a plnion 164accommodating the endthe top board being deposited less chain 146 for transmitting the rotation imparted thereto to shaft 143. The cam 163 has such formation that, at desired moments in the operation of the machine, the cam will impart actuation to lever 156 towards the left causing the plunger 154 to likewise travel towards the left, as viewed in Figure 4, for accomplishing the feeding of the instruction sheets as described. Also located in the vicinity of shaft 160 is a transverse shaft 165 mounted upon bearings 166 and provided at one end with pinion 167 and at the other end with sprocket 168. The sprocket in turn is operatively associated with sprocket 151 through means of the endless chain 152 so that the continuous rotation of shaft 165 is imparted to the pressure rollers 147.

The receiving belts 9 are adapted to have continuous rotation supplied by means of belt 170, Figure 2, to pulley 171, the latter secured to shaft 8 upon which are mounted the pulleys. Likewise shaft 17 2 is continuously rotated through means of the endless chain 173 associated with the sprocket 174 secured to the shaft. Upon the other end of the shaft a gear 175 is secured and through its engagement with pinion 167 transmits continuous rotation to shaft 165. Also secured to shaft 172 at its respective ends are sprockets 176 and 177 respectively, the former sprocket being associated with the endless chain 28 to drive sprocket 27 on shaft 26 and the latter being associated with the endless chain 69 to drive gear 68 on shaft 66. It is, of course, understood that belt 170 and chain 173 are in turn suitably connected to any source of power independent of the power means to be described.

Referring to Figures 1 and the electric motor 180 is provided with driving pinion 181' on one end of its rotor shaft and friction brake mechanism 182 on its other end. Electric means 183 upon energization is adapted through suitable linkage to cause actuation of the brake. Meshing with pinion 181 is pinion 184 suitably journal-ed in support 185 and having provided on its opposite end a worm gear 186. Also rotatahiy mounted in support 185 is an operating shaft 18. upon which is fixedly secured a gear188 and an intermediate gear 139 meshing with worm gear 186 and a pinion 190, the latter being operatively associated with endless chain 163 for driving shaft 160. Located adjacent support 185 are spaced supports 191 upon which is journaled shaft 192. Secured intermediate shaft 192 is wheel 193 meshing with gear wheel 188, while located upon the shaft at its respective ends is a crank arm 194 provided with roller 195 and a crank disc 196 having. pivotally connected thereto through stud 197 the arm 198. As shownin Figure 2-Ithe arm 198 is pivotally connected to the ratchet bar 200 mounted for reciprocation upon supporting mcinher 2011.

Adapted to have meshing engagement with ratchet bar 200 is a gear 202 secured to an up rightshaft 203 suitably mounted in bearing 204 and provided at its upper end with the operating arm 205, having secured thereto a link 206, its opposite end pivot-ally secured to block 207 through means of stud 208. The block 207 is adapted to have slidable movement withinthe spaced channels 209 and has integrally connected thereto, as shown in Figure 3, the pusher arm 82. Through the operating mechanism described, it is seen that upon operationof motor 180 the necessary rotation will be imparted to gear 202 causing rotation of shaft 203 and arm 205 to impart the necessary reciprocation to block 207 and thus pusher arm 82 and the delivery arm 80 forperforming. the operations described.

Rotation of shaft 192 will likewise cause rotation of crank 194 whereupon at the completion of a revolution roller 195 will strike the stop 210 suitably secured to the end of the slidable shaft 211. Secured intermediate shaft211 is the cont-act shaft 213 provided with contacts 214. Located upon "the depending plate 215 are cooperating contacts 216 which, as it will be seen, are out of engagement with contacts 214 with the shaft 211 in'the position shown. The operating shaft 211 is in turn secured, as shown in Figure 3, to the rotatably mounted shaft 217, the shaft extending through the frame of the vertical conveyor and terminating within the conveyor frame, as shown in Figure 1. When it is desired to operate motor 180 to cause the parts associated therewith to complete a single cycle of operation, it is only necessaryto reciprocate shaft 211 to close contacts 214 and 216 and this reciprocation of the operating shaft is caused, as shown in Figure 2, by projections 218 suitably secured to certain of the bars 46 to which in turn are secured the arms 44, as described. The projections 218, during their downwardmovementwith the endless chains 36 of the vertical conveyor, engage the safety arm 220 and subsequently the actuating arm 211, fixedly secured to the end of shaft 217, to impart suflicient rotation to shaft 217, to cause slid able movement of shaft 211, to close the contacts to the motor.

The safety arm 220 and actuating arm 221 are operativelyconnected in such a manner as to provide a safety device which will pre vent inadvertent movement of shaft 211 to start operation of the motor, which would result in considerable dam age, but which oper ates to permt the closing of the contacts only when the spaced arms on the vertical .conveyorare in such a position as determined by the location of the projections 218 to allow the pusher arm 82 and the delivery arm 80 for the bottom boards to be operated and to clear the supporting arms disposed adjacent thereto. Supported upon a base 222, Figures 10 and 11 located within the frame ofv the .ver-, tical. conveyor: is an angle arm 223 to which is pivotally secured by stud 224 thesafety arm 220. The angle arm in turn is provided with an upstanding portionhaving apertured projections .255 provided thereon in spaced relation for accommodating the slidable pawl 226. The upper projecting end of pawl 226 engages the fixedly mounted stud 227 on the actuating arm 221, while secured to the base of the pawl is a pin 228. The pawl is resiliently urged in an upward direction by the coil spring 230 so that normally the upper end of the pawl will have engagement against stud 227, and since the angle arm 223 is firmly secured to the base, it will :be seen that the arm 221 cannot be operated in that particular direction to cause closing of the contacts to the motor. Under actualoperating conditions the safety arm 220 will first be actuated by engaging with projection 218, and the pivotal movement thus imparted to the arm will cause a retracting of the pawl 226 since the pin 228 has engagement within the slot 231 provided in the safety arm. This retracting of the pawl willoperate to free the engagementof the same with the stud 227 and as the projection 218 continues its downward movement its engagement-with arm 221 will impart the desired rotation to shaft 227'and the rotation will take place since arm 221 will be free to rotate. I

Although a description of the operation of the Various parts of the machine has been given, in order to more thoroughly ru1derstand the same a resume of the operations will be given by following the course of the shingles from the time they are deposited on the belts 9 until they are discharged from rollers 85 ready for the tying operation. The bundles of shingles are received by the belts Sand as they, approach the discharge end of the belt circuit they are positively removed therefrom by the pusher arms 21.- It is understood that the arms 44 have intermittent movement and are lowered step by step as the bundles are deposited thereon. The ratchet wheel 54 has been designed so that as yoke 51 oscillates shaft 42 will be rotated in amounts equal to the distance between the notches 55. During this rotation arms 44 are lowered and simultaneously therewith the bundles are deposited thereon. Rotation of shaft 42 continues until pawl 61 engages notch 58 whereupon the shaft 42 will be rotated approximately a third of a revolution, this rotation being suflicient to cause lowering of arms 44 to deposit the bundle thereon upon the rollers 76. It will be seen that this construction allows a certain number of. shingles to. be deposited on the arms and by substituting for the wheel 54a modified form of ratchet wheel having four or five notches corresponding to notch 55,that the number of shingles deposited on the arms can be i n "e 3 it will be seen that varied.

Referring to 1 g 1 as the bundle of shingles 7 is termed and deposited on the rolle s 76 an operation takes place prior thereto to locate upon the arms a bottom board 78. This operation results from actuation of the arm to cause reciprocation of arm 80. Reciprocation of this arm simultaneously actu ates arm 82, which is a pusher arm, to push the bundle (5 on the rollers and locate the same in position between the deflecting plates 108- and 109, Figure 1.

The next operation is to deposit upon the bundle or stack of shingles a top board 72 and this is accomplished by actuation of shaft 105 to cause reciprocation of arm 102. Simultaneously this operation however is necessary to feed an instruction sheet from the magazine containing the same and to deposit the ins ruction sheet between the top board and the top shingle of the bundl The feeding of the instruction sheet is accomplished by rotation of shaft 160 which is driven by belt 103 and which in turn drives the belt 146 imparting actuation to the container mechanism. The device of the present invention has been constructed so that actuation of the pusher arm 82 and arm 80 to remove the bundle from the path at the arms a l, the feeding t icreto of a top board 92 and of an instruction sheet 1-l4l as described takes place simultaneously, the mechanism necessary to cause actuation of the same being dependent upon the electric motor 180.

As stated in this description the motor 180 is controlled through electric contacts 21-1 and 216, while the contact 21% has reciproca tion in accordance with therotation ofrod 917. This rod is provided with an actuating arm 2'21 and a safety arm 220 which are engaged by the projection 218 at the proper time to cause closing of the contacts to the motor to start the actuation of the mechanism described. its disclosed in Figure 4 it will be seen that the motor 180 through pinion 181 will impart rotation to shaft 187 and shaft 192. the former shaft through belt 163 driving the shaft 160, while rotation of the latter causes reciprocation of ratchet bar 200 and simultaneously drives belt 232 to impart rotation to shaft 233 and through belt 234- to shaft 101 to cause feeding of the top boards 92.

he reduction gearing between motor 180 and shaft 192 has been lesigned so that one revolution or" shaft 192 is suflicient to impart the necessary rotation to the mechanism described. Accordingly arm 19-l secured to the end is adapted to engage the step 210 secured to the shalt 211 to cause reciprocation oi the latter shaft towards the left as viewed in Figure l breakin the contacts 214 and 216 and thus stopping the electric motor. The mechanism driven by motor 180 therefore remains at rest until another projection 218 engages the arm 221 to again close the contacts. It will be understood however that the belts are driven from an independent source of power associated with belt 173 imparting rotation to the main driven shaft 172. Also, it will be clear that the vertical conveyor is driven through the same mechanism, since belt 09 serves to rotate shaft 66 and by means out crank and arm Gel the yoke 51 is oscillated as described.

it is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit oi the invention or the scope of the claims.
