Application-filed February 28,1912.- Serial No. 680,550.

and. CHARLES M. SHAPERA, citizens of the' United States, and residing at Qhicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Cloth-.Filing Machines, of whlch-thefollowing is a specification.

Our invention relatesV to cloth piling ma4 chlnes and involves variousgfeatures of 1m- .pr'ovement over what is disclosed in our Patent Number' 964,121 and our latent Number 1,002,459, issued respectively 'July 12th, 1910, and September 5th, 19.11."

Among the important objects ofour present invention are: to -provide-l improved abutment mechanism forV stopping without shock, the carriage at the ends of its back and forth travels on the track-and to'start the carriage on its reverse travel independently of .the carriage propelling motor; to provide improved construction, operation and control for the guide barmechanism; to provide pilot mechanism for determining the amount of raising orlowering of the Y guide bars with reference to the cloth piled on the table; to provide improved clutch.

mechanism to be operated by the pilot mechanism .to control the 'connection of the guide bar adjusting mechanism'with continuously operating drive mechanism; to provide improved clamping mechanism for cloth laid on the table and improved cooperation of such clamping mechanism with the guide bar mechanism; to provide manually controllable lmechanism for enabling the guide bars to be independently raised or lowered; to provide improved guiding means for guidingr the cloth from a bolt over and about the v-arious cloth guide rollers Vand rods so that the'cloth end can'be more readily inserted between the guide bars' preparatory to piling the cloth on the table; to provide improved means for' maintaining proper tension onthe cloth while it) is being piled: to combine the abutment mechanism and clamping mechanism at each end of the table into a unitary structure having clamping mechanism for adapting it to be readily applied to or entirely detached from the table; and in general to provide more improved and -eilicient construction in a machine of the character referred to.

All the various features of our invention v,are illustrated on the accompanying drawings in which,V

The operative parts are mounted on a table 1 and comprise the carriage C, and an abutment frame J and-clamping frame J at each end ofv the table; the tracks 2, 2 being y l provided on the table for accommodating .wheels 3 of the carriage. The carriage comprises front 'andrear frames 4 and 5 connected together by suitable beams or bars 6, the side frames each comprising vertical end bars 7 and 8, iop and bottom horizontal bars 10 and 11, and an intermediate vertical bar `12'and horizontal bar 13. A wheel is pivoted to each lower corner of the frames, those at the left being each provided with a. sprocket wheel 14, the sprocket wheels beingcolmected by .chain belt-s l5 with sprocket pinions 16 on the propelling shaft 2 l neergezetA 17 yextending transversely through the carframes. Pivoted toV rotate loosely yon this shaft are forward and reverse `bevel gearsl 19 and 20 both 'permanently in mesh with a drive .pinion 21 on the Ishaft of the -electric propelling motor 22'. The front end of the propelling shaft is' tubular and journals a smaller shaft 23 carrying at its inner end the transverseclutch bar 24 extending out? wardly through slot l25 in the shaft '17 between the bevel gears.` The inner faces of the gears 1,9 'and' 20 have clutch teeth`26 and 27 respectively, the clutch bar," when in its outer position, coperating with teeth .26

^ 'Sto connect the-motor in l forward vdriving re- .'l'ation `with the shaft 17, and when in its inner position, coperatingwith teeth 2f? to 20 'Connect the motor-,nin reverse'jdriving relation with said shaft? The shaft terminates at its front end in collars 28 and 29 between which engagesa fork 30 whose arm 31 is 'pivoted aty an intermediate point on bearing 2 5 `frame 32 secured'to front bar 13. A' bracket 33 on front vbar 12 and between front bars 1l and13 pivots a longitudinal clutch lever 34 at its center to beswung in a horizontal plane. v' The lever, between its pivot and its 30 left end has blocks 35, 35 clamped thereto and forming asocket 36 for the lower ball ,end 37 of arm 31 of the fork 30, so that as lever 34 is swung back and forth; the fork.

`will be moved back and forth to move clutch fshaft'23 out and in to connect the motor for forward or reverse driving. When the lever is in neutral position the clutclrbar 24 will .be midway between the clutch teeth of the gears and Athe driving shaft is not driven,

'p 40 although theA motor runs continuously.

'The'clutch lever 34 is formed from a flat bar,I its ends 34 and 34 being bent grada ally forwardly. The ends of the lever rest on and slide overgbrackets 38, 38 respec- 45 tively, ,extending forwardly from the front frame 4. The lever is yieldingly locked in neutral positionby detent plungers 39 whose wedge heads `40, 40 are pressed by springs v 41, 41" toward notches 42, 42. formed on brackets 38, 38 respectively. When the lever is swung from neutralposition the wedge detent heads of the slotsand when the lever is returned to neutral position the heads are returned 'to 55 lthe slots and lock the lever in neutral position. Near'the ends of the ,lever and on top lthereof are pivoted pawls 43, 43', springs 44,44 tending to hold the pawls in diagonal @position with their *inner ends extending to- GQward each other. These pawls coperate withthe abutment frames J as will be explainedlater. i

-Each abutment frame J comprises side standards 45 and 45 connected at their 4 65 bases by a cross board 46. The standards are forced out have brackets 47, 474, respectively, eXtending downwardly adjacent the sides of the table 1, and t-he brackets pivot, respectively,

lthe bell crank clamping levers 48, 48.A The lower arms 48l of these levers extend in- 70 wardly below the sides of the table to firmly clamp against the table bottom when the upper arms 48b are swung outwardly. To control the rotation of the levers, we provide a lever 49, pivoted to the board 46 at 75 50, and connected above and below its, pivot with links 51 and 52 respectively, the outer ends of these links being pivoted to the'ends of arms 48b of the levers 48 and 48.' lVhen A the lever 49 is vertical, as shown in F ig. 7, 30 the clamping levers 48 and 48l release the table, but when the lever is swung to horizontal position the clamping levers are rotated to securely` clamp the table to lock the abutment frame thereto. S5

.Each of the standards 45 and 45 carries at its upper end a barrel 53 having a plunger rod 54, the plunger rods of the two abutment frames extending inwardly toward the Carriage C to'be struck by the abutment lugs 90 55 and 55 at the opposite ends, respectively7 of the. intermediate horizontal bars 13 of the 'front and rear carriage frames 4 and 5, such engagement beingl illustrated in Figs. 5 and 6. f

. y es Referring to Figs. 5, 6 and 9, each barrel Ahas the end caps 56 and 57, the plunger rod extending through the cap 56 and secured to a .piston or plunger comprising rings 58 and 59v clamping between them a leather -100 lwasher 60. l Between the ring 59 and Ithe cap 57 is interposed a compression spring l6l for resisting the inward thrustof the plunger rod. A rod 62- secured to the cap 57, extends through the barrel and into the hollow plunger rod to guide the plunger rod. Each barrel is longitudinally adjustable by being within a split sleeve 63 at the top of its respective standard, the sleeves being clamped to the barrels by screws 64. V Each front standard 45 carries on'its front side an arm 65 pivoting at its end a Cam roller 66 for coperating with the ends 34 and 34v of the clutch lever 34 and the rpawls The co-ntrolof the bod-ily movement of the carriage can now be clearly understood. Suppose that the lever 34 has been swung clockwise from neutral position (see 34L Fig. 5), the left end thereof will be in and 120 the clutch mechanism willhave been set to cause the motor to propel the carriage toward the left. `When the carriage appreaches the left end of the track, the lugs 55 will strike the abutmentv plunger rods 54 125 at the leftend 'of the table and will force these rods inwardly against the resista-nce of the springs 61. Just before the plunger rods are struck, the end 34 of clutch lever 34 will strike cam roller 66 (see dotted lines 130 v forwardly by the cam roller.

lines Fig. 5).

'cientdistance to allow recessive-"1 Fig. 5), and the clutch bar will be moved to normal position, (see full-lines Fig. 5), to disconnect the driving moto-r just before impact of the carriage with the plungerv rods, but the carriage, owing to its momentum, will continue toward the left' a suffithe pawl 43 to swing havingfbeen swung (See dot-dash Thepower acquired by the back to .normal after Asprings 61 when thus compressed by the carriage, will rst stop the carriage and will then start it on its movement toward the right.` After a short distance of'such travel, the cam rollerl 66 will engage .between the teeth 43? and'43b of the pawl 43 and the pawl will be swung toward the left,

(see doubledot-d'ash lines Fig. 5,) such swing causing the'clutch lever to be swung in counter' clockwise direction from its normal.- position thereby to adjust the clutch lmechanism to, cause the motor todi-ive the .carriage to continue its travel toward the u right.

When the carriage appro-aches the right end of the table, its lugs and the .clutch bar end 34 and the pawl thereon .will coperate with the right end cam roller and plunger mechanism and vthe lever 34 y will be moved to neutral position, the mot-or then disconnected,- and the carriage. thenI stopped and then'started by the plunger v springs on its travel toward the left. Thus the 'motor is relieved of the-heavy burden ofreversing the travel of the carriage, the 'abutment plunge'rs first taking up and cushioning the shock of stopping the carriage and-then giving the carriage a good start in the opposite direct-ion before the motor is'again connected to-take up the propulsion.

A. cloth feedingandguiding frame F is 'mounted .on the carriage() yand comprises side standards 67 and 68 mounted on the right ends of the front and. rear frames 4' and 5 respectively', the standards extending upwardlyuand then towardv the left and' terminating substantially over the center of the carriage. A rod 69 connects thewends of the standards and journals a roller 70, while a rod 71 connects the standards at their bends and 'journals' roller 72. A. shaft- 7 3 connects the front and rear frames?) and 4 below roller 72 and journals rollers 74'. A f bar 75 is also secured to the ends ofthe standards'and carries a tension jaw plate 76. In upward extensions 77 and 7 8.on the ends of the standards 4a `rod79 is secured for supporting hinges 80 carrying the tension jaw plate 81 for coperating withjaw plate 76.

On the top of the front and rear carriage lframes 3 an'd 4 4a table v82 is provided for supporting bolts of cloth -B to loe-spread land laid. T he cloth passes from the bolt between the jaw plates 76 and 81,' then .over

rollers 70, -72 and73, then over shaft 84:,.and

then downwardly between vthe guide-bars 85 I and 86which will later be described. In order to. adjust the tension on the cloth tension jaw 81 is provided with weighted arms 85 which tend to force the tension' jawstogether .to clamp the cloth, and set screws 86'- extend through one of the ja-wframes and abut against the other,i these set. screws serving to adjust the gap between the aw plates to thereby adjust the pressure ot the jaws on the cloth.

The guide bar supporting mechanism is best shown 1n Figs. 2, 3, 4, 5 and 6. Blocks 87 and 87are provided for the front and rear frames 4 and 5, each block having a vertical rectangular guide r1b'88 engaging 1n a. gu1de slot 89 formed 1n the vertical bar 12 of the frame so that the block may slide.

up and down.- .lach rib has a threaded opening S9for receiving a screw 90 ter minet-'ing at its top 1n a bevel', gear 91 and -journa'led in the bearing bracket 92 eX- vas will be described later. Each block at its sides has vertical grooves 9 6 'and 97 forreceiving the slide bars` 98 of the" opposite blocks 87 and'87 .which bars support at their.' tower' ends the guide bar 85wliile the slide bars 99 support at their-lower ends the guide bar 86.. These guide bars are in the form of anglebars'and, are arranged side by side-withtheir .vertical flanges at the outside and with their horizontal flanges normally in a common plane and-separated by a narrow gap of sufficient width to allow passage of the cloth between them, bars 98 and 99 have .respectively at their upper ends the inwardly extending pins 100 and 101 engaged respectively by the forked ends 102 and 103 of bell crank levers 104 and 105 pivoted at Atheir elbows to the brackets 106 and 10T4 extending from the corresponding 4block 487. The downwardlyV "extending arms 108and 4109 of -the bell crank leversterminate in shoes l110 and 111.4

respectively. "Pressure on these shoes toward the block 87 will cause the bars -98 The and 99 andthe guide bars supported thereby to be raised. Such pressure on the shoes is controlled automatically during engagementv of thecarriage with the clamping 'frames J at the ends of the track. Referring .to

frame J. Cross bars and 116 connect to# gether the outer and inner ends respectively of the bars 112 and 113, the frame being further strengthened by longitudinal bars 117 and 118 connected to the bars 115 and 116'and pivoted at the 'outer ends to the shaft 114 as shown. The bar 116 is comparatively heavy and has the points 119 extending downwardly therefrom for receiving the cloth from the guide bars and holding the' various layers in place after laying thereof. On each of the bars 112 and 113 a bracket 120 extends upwardly about midway of the bar, and at the outer end of each bar an.

'and 6 the carriage has traveled toward the left and the shoes 11() have engaged the plunger rods 121 to push these rods outwardly and to raise the guide bar 8?). The guide bars 85 and 86 have abutment lugs 126 and 127 secured thereto against which' the shoes abut upon swing of their bell crank levers, such engagement being shown in Fig. (i.

As before described the cloth coming from the feed frame F passes down through the gap between the guide bars 85 and 86. As the carriage travels back and forth the advance guidebar-is lifted as has been described, to allow the other guide bar to tuck the cloth under the points of bar 116 of the To enable the bar 116 to be readily lifted to allow insertion of the cloth, a trip latch 128 provided at. each end of each guide bar, These .trip latches are best shown in F igs.4 5, 6, 10, 11, 12and 13, each being in the form of a plate pivoted at itsrear endin the bend of the gui-de bar and extending forwardly to the inner edge of the guide bar against which it normally rests. Each latch plate has at its outer end a laterally extending diagonal web 128 for coperating with a diagonal cam plate l129 extending laterally from the corr esponding bar 112 or 113 of the clamping frame J. As.

shown in Figs. 5,. 6,10 and 11, the advance 'guide bar has just been raised -by engagement of the shoes 110 with the 'plunger rods 121", and the webs 128 of the trip latches 128 ofthe other guide bar are just about ,to engage under the diagonal plates 129 on bars 112 and 113. Upon such engagement the clamping frame is4 swung upwardly about shaft 114, as shown in Fig. 12 and the bar 116 is raised, sufficiently to allow the edge of the guide bar to insert or tuck the cloth under the points 119. 'Before the carriage is stopped and recoiled by the abutment mechanism lthe latch webs will have passed beyond the plates 129 and the bar 116 allowed t'o drop to hold the cloth just received thereby. As thc carriage now begins tra-vel in the opposite direction the diagonal webs of the latches will slide over the tops of the plates 129 as shown in Fig. 13,-the latches merely swinging idly upwardly and th'en falling back tonormal position. Then the carriage reaches 'the clamping and abutment mechanisms at the other end of the track the same operations are carried out by the guide bars, a new layer of cloth being each time added to the pile on the table. y

' The entire'guide bar mechanism must of course be raised gradually as. the pile on the table increases in height', and. the guide bars should at all times glide smoothly over the cloth. To accomplish this we provide mechanism which automatically controls fthe raising and lowering of the guide vbar supporting blocks 87 and 8T to keep the guide 85 and is adapted to move vertically by engagement oflits end extensions 131 in guide plates 132 secured to the guide bar. Then these extensions reach the bottom of the guide plates the loweredge of the pilot bar extends a short distance below the lower edge of its supporting guide bar. L tending 'up from the middle of the pilot bar is pivoted to the horizontal arm of a bell crank lever 133 which ispivoted at its elbow to the vertical flange ofthe guide bar. The vertical arm ofthe lever pivots at its'end to the inner end of a connecting-rod 134 whose other end pivots to the lever 135 at an intermediate point thereof. @ne end of this lever is pivoted to a lug 136 on the guide bar structure while its other end Ahas the slot 137 receiving the crank pin 138 on crank lever 139. The hub 140 of this crank lever receives a vertical shaft 141 having the longitudinal channel. 142, a pin 143 in hub 140 extending into` this channel so that the shaft will turn upon swing of lever 139, the lever being free, however, to slide vertically along the shaft as the guide bar mechanism sup po-rtingblocks are raised and lowered. The

lower end ofthe shaft 141 journals in a bearing block 144 extending inwardly from A lug 1327 ex- 1 has no gear teeth.

-146 is secured to the upper end of shaft 141 above the bearing block 145. The end of lever 146 has slot 147 receiving pin 148 eX- vtending downwardlyfrom the shaft 149 journaled in the hubq 15()f on the bar 12 of side frame 4 of the carriage. Vi'th this arrangement of transmission mechanism between the lichting pilot bar 130 and shaft 149, raising of the bar. causes rotation of shaft 141 to cause the shaft 149 to slide forwardly, while dropping of the pilot bar will result in rearward slide of shaft 149. Vertical movement of the pilot bar will result in corresponding movement of the guide bars by mechanism which will now be described. l

0n the shaft 84 which controls the screw shafts 90, a` ratchet collar 150 is secured adjacent the hand wheel 95,and on the saine shaft adjacent the carriage' frame is a ratchet collar 151, the collars having teeth on their inner faces. Slidable on shaft 84 between the collars is a wheel 152having ratchet teeth on its opposite faces, and hav- 'ing gear teeth 153 extending part way about its periphery. Secured to the outer end ofshaft-149 is a head 154 whose forked end receives that part 155 of the wheel 152 which Back and .forth movement of wheel upon raisinglyand lowering of the pilot bar will result in backward and forward slide on shaft 84 of the wheel 152 to carry its ratchet teeth into engagement with the teeth on collars 150 and 151 to turn .shaft S4 one way or the other, the` the propelling shaft rotates the lever 157 A rocks and wheel 152l is oscillated through an arc of revolution. As the pilot bar 130 rises and falls the shaft .149 moves forward and back and the wheel 152 carries its front and rear ratchet teeth respectively into engagement with- ratchet collars 150 and 151, and. ifwhel 152 is .oscillating the shaft 84 will rotate one way or the other. The teeth on Ithe frontfaceof wheel 152 and on collar 150 are so .inclined that engagement thereof blocks-87 and 87.

will cause shaft 84 to rotate clockwise so that. the 'screw shafts 90 will be turned to raise the guidebar mechanism supporting In other words, when the wheel 152 and collar 150 are in engagement the shaft84 will be advanced 'clockwise during .clockwise oscillation of wheel 152 by rock lever 157, while during counter clockwise rotation of wheel 152 by the lever 157 the ratchet teeth i glide idly over each other. 1n the same manner shaft- 84 is ro tated counter-clockwise to cause lowering of the blocks 87 and 87 when wheel152is`shifted into engagement with collar 151. Thus whenever wheel 152 engages with one. ofthe collars 150 and 151 the guide bar blocks 87 and 87 will be raised or lowered, while when wheel 152 isv in neutral position it will still oscillate but shaft 84 remains at rest. The guide bars. thus move synchronously with the plotbar as the .pilot bar shiftsvertically to follow the gradually increasing height of the pile on the table asA layer after layer is added. .The height of the 'pile also varies due to uneven thicknessofthe `cloth at differentpoints, but the pilot barcan readily follow the varying level and the I guide bars automatically follow and always remain intimately. against the cloth to smooth it outl and to prevent it from wrinkling. lhen the carriage approaches the leftend of the traclrand the 'guide bar carrying thepilotbar is raised upon impact of bell crank levers 104 with the clamping -frame J the pilot bar will drop as far-as plates 132 will permit. However, by this vtime the. motor will :have been disconnected from propelling shaft 17 'by actuation of will have been shifted against collar 151 it .clutch lever 34 so that although wheel 152l wil-l not be turned. The pin 138 ofcrank y lever 139 isextended upwardly suihciently'4 so thatl lever 135 will remain inengagement therewith during. raising of the guide bar which carries this lever l135.

' As before described shaft 84 can be controlled manually by hand `wheel to raise the blocks -8'7 and 87 carrying the guide bar slides. Provision is also made lfor man# ually raising' either guide bar. As best shown in F ig. 4 each slide bar 98 and 99 has a longitudinal bore 160 for accommodating a rod 161 having the head 162 at its lower end. The mouth of each bore is conroo tracted to prevent escape of the head 162v therefrom but to allow free verticalslide of- ,the rod in the bore'sothat the slide bars l withhthe 'guide bar supported therefrom can move vertically freely and independently -of the rods161. Connecting the left .ends of the carriage frames 4 and 5 Ais a shaft v163 frames the drums 164 and 165. -Achain lcarrying at its ends and just withinthe l or cord 166 winds about each drum 'the` chains passing over sheaves 167 journaled to the corresponding carriageframesover the rods .161 of the adjacent slide bars 98, the ends ofthe chains connecting with the up.

pei' ends of the rods. Thus turning ofshaft 163 by a handwheel 168 at the front end j thereofwill cause, raising of the rods 161 until the rod heads engage the contracted mouths of the bores in the slide bars, and

Likewise the shaft 73 connecting the right ends of the frames 4 and 5 and journaling roller 74 already referred to, also mounts drums 170, from which lchains. 166 pass over sheaves 167 and to the rods' 161 of the slide bars 99, the shaft having the hand wheel 171 at its front end.- Thus each guide bai` 'can 'be independently raised manually.

A hand wheel 182 is secured to the front end of shaft7l by means of which the chain. can be propelled.v The end of the cloth of a fresh bolt is first passed between the jaw `bars76 'and 81 and then over roller 70, the

clo-th being then hooked to one of the hooks 4178 and'thehand Wheel 182 turned. The 'cloth will then be carried by the chain over u rollers 70 and 72, then about roller 74, then` Aframe 4, the' other arm of the lever being slotted to receive pin 188 on bar 189 connecting levers 190 and 191 pivoted to frame .4 near the left and right ends thereof. Lover 190 has a downwardly extending arm 5190 -Which strikes the abutment standard whenever the carriage reaches the left end of' its travel, each actuation of the lever causing bar 189 to move to 'the left to swing bell crank lever 187, and to actuate the Lever 191l has teeth 192 meshing to bar 8, the 'arm 194 extending from the segment abutting against the standard 45 at the right e'n'd oi" the table each time the carriage 1movement the pawl 43 will abutment reaches the right end of its travels, and bar `189 is again moved to the left and the regvously. If the carriage travels.- toward the left as indicated in Figs 5 and G the clutch lever 34- vvill be in its inner position at the left end. Before the abutment lugs strike the abutment. plungers the end 84 of the clutch lever will engage with roller GG and the clutch lever will be shifted to neutral position to disconnect the motor from driving engagement with the carriage. The shoes 110 will strike the plunger rods 121 and the advance guide bar will be raised as indicated in Fig.` G, and the trip latches of the guide bar 8G will just about engage with the clamping' frame J. The plunger abutments have by'this time received the CarriageD to retard its movement and to eventuali;1 stop it and recoil it to start it on its reverse travel. Before the carriage is stopped, the trip latches on guide bar 86v will have lifted frame J yto tuckl the clotch under the bar 11G and points 119, and after passage of the trip latch plates 128 past the plates 129 on bars 11,2 and 113, the frame J falls andthe to hold it while the carriage travels tothe right. lVhen the carriage begins its return engage roller 6Gl to swing out the end 34 of the clutch lever so that the motor is clutched in to take up the propulsion of the carriage to the right. Then the carriage lreaches the right end of its travel it cooperates with the frames J and J at that end of the table and guide bar 8G is raised to allow guide bar 85 to tuck the cloth under the frame J whereupon the carriage is recoiled and its propulsion to the left taken up by,the motor. T he floating pilot bar 130- follows the increasing height of the pile and the varying levels thereof and the guide bars are correspondingly adjusted as has been described.
