Patented Apr. 21, 1931 PATENT :oFFicE ram; urrrnnor CORONA, NEW YORK DOBBY-LOOM CHAIN Application filed March 7,

This invention relates to pegging machines and is directed more particularly to improvements in pegging machines of the character described and claimed in my Patent No.

1,520,159, issued December 23, 1924:. In the patented machine, mechanism is provided for the pegging of loom bars in a thoroughly efficient and practical manner. The bars, which in practice. take the form of perforated wooden bars are supported and successively fed into a position wherein pegs may be mechanically delivered to and, secured in pre determined perforations of the bars. The pegs are normally contained in the hopper 5 or magazine and are adapted to be fed by a my boardoperatedescapement and in a selective manner into positions with reference to predetermined holes in the bars, and after a series of pegs have been positionedfor association with any particular bar, manually operable means is utilized to screwall of such pegs simultaneously into the corresponding holes in the bar.

The present invention operates upon the same general underlying principle, but difi'ers from my prior achievement, among other features, in the provision of improved means and mechanism of feeding the pegs'intoposition to be applied to the bars, in improved and novel means for applying such pegs to the bar, and in improved and novel means in the selective feed of the pegs into positions to be applied. 7

A; further important feature ofthe invention consists in the provision of means to facilitate or guide the operations of the keyboard in order that an operator may 'more readily determine the particular keys which are to be actuated in order to efiect a predetermined positioning of the pegs with respect to the respective bars; 7

Another, highly important feature of the present invention consists in the provision of mechanism, so constituted that a loom chain may be fed to the machine with pegs associated therewith, a mechanism functioning to remove the pegs which are associated with the bars and to thereafter apply other pegs in predetermined positions appropriate to the new design to be produced through the embodying the present invention.

Figure 18 is a perspective view of one of the parts showv in section in Figure 4.

Referring to the drawings, 1 designates the base of the machine. On the rear portion of this base are upstanding side plates 2 and 3 rigidly secured to the base in upstanding parallel relation to one another. Between these side plates are mounted two carrier rolls 4 and 5 placed one above the other and both mounted to rotate. The n iper roll 5 is mounted to rotate in any suitable fixed bearings carried by the side plates, while the lower roll 4 is mounted in hearings of the character shown in Fig. 9. As here illustrated, the roll is provided at its opposite ends with trunnions 6 which pass thru hearing blocks 7 and are journalled for rotation therein. These bearing blocks are mounted to slide in 45 degree angle slots in the side bars 2 and 3.

Mounted on the exterior face of the plate 3 is a. ring or annulus 8 at diametrically opposite sides of which are formed helical slots 11, the axis of which slots is the axis of the roll 4.. Extending through the slotsan operating lever 9 and this lever is perforated as shown to fit over the trunnion 6. A large headed screw 10 is screwed into the end of the trunnion and binds the operating lever to the trunnion while permitting the trunnion to rotate.

By a relatively small amount of arcuate movement of the operating lever, the hearing blocks 7 at both ends of the roll are slid longitudinally to shift the same laterally in one direction or the other to a predetermined degree as hereinafter more fully explained. Sufiice it here to say that the purpose of this mounting is to permit the machine to cooperate with bars embodying either a double row of peg holes or a single set of peg holes appropriate respectively to the so-called double harness or single harness operation.

The sliding bar block arrangement shown in Fig. 9 is duplicated at both ends of the roll 4. although the ring 8 and operating lever 9 are used at only one end of the roll.

The trunnion at the other end of the roll is extended and has mounted thereon exteriorly of the side plate 2 a ratchet wheel or gear 12, which, when rotated, with step by step movement, imparts a like movement to the roll 4.

Both the rolls 4 and 5 are provided in their outer circumference with depressions or recesses forming pockets 14 and 15 adapted for the reception of loom chain bars which are designated generally by the reference character C in the respective figures. The pockets 14 and 15 are spaced equidistant around the circumference of the respective rolls and at such distance apart that when the bars are linked together to form the chain as is common in practice, this chain of bars adapted to pass about the respective rolls as indicated in Figs. l, 5 and 6, the respective bars engaging the recesses of pockets 15 and A as indicated in these figures.

It may be here noted that the roll t is the pegging roll, i. e., the roll at which the pegs are applied, whereas the roll 5 is the roll adjacent which the previously used pegs are removed from the bars.

In the machine of my prior patent, no means was provided for removing the pegs after the card chain had been used. They have heretofore been removed by hand. The present machine is so constructed that a used chain may be run through the machine, the machine functioning first to remove the pegs already in. the chain and to thereupon feed the chain by a step by step movement to a point of application of pegs for the new ar' rangement or set up desired. To this end the chain is fed first over the roll 5 and directly upon leaving said roll comes into cooperative relation with peg removing n eans indicated generally by the reference character 16; here all the pegs are removed from the bars as each bar is in cooperative relation to said means. The bars pass from said means free of peas and to the roll 4. While the bars are retained in the pockets of the roll 4, the new peg arrangement is applied. My prior patent shows key board operated mechanism for applying pegs to bars and the same general arrange ment is employed in the present machine with, however, such improvements as practice has shown to be desirable.

Thus in the accompanying drawings, 17 designates a magazine in which the pegs are adapted to be contained and they are adapted to be fed from this magazine or hopper by means of a number of traclzs or guides 18 to a series of wrenches 19, in substantially the same manner as described in connection with my prior patent. The feed of the pegs to the wrenches selectively is controlled by a key board. operated escapementor feeding device. The keys are designated 20 and are actuated the same as typewriter keys by the fingers of the operator. Each of these keys controls the escapement or feed mechanism of one of the tracks 18. Thus, as shown in Fig. 4,

for example, the rear end of the key lever2l engages with the hook end 220i the swinging plate 23,which is provided at its upper'end with a nose 24. y 7

The normal positionof the parts is as illustrated in Figure 4, wherein it will be noted v that the nose 24 of the plate is in retracted position between the ends and in cooperative relation with escapement mechanism. This mechanism which is shown in detail in Figures 14, and 16 embodies a pivoted member mounted on a pivot pin 26 with which co of one peg, so as to take one peg between them. I The position of a peg against the finger 29,

however, is but momentary, for, under normal conditions, the plate 23is retract-ed into the position shown in Figure 4, so that said plate engages with the cam member 38 and thus tilts the escapement fingers, so as to V retract the finger 29 and force the finger 28 into the path of the gravitating pegs. Thus under normal conditions, the pegs are held together by the finger 28, while one peg of each track has passed beyond thefinger 29 and is resting on a substantially horizontal part of the track as indicated in dotted lines in Figure 4. In other words, there is at all times a peg in substantially the dotted line position of Figure 4 for each track awaiting the pleasure of the operator. Now if any appropriate key 20 is operated, the swinging plate 23 will move in a'clockwise' direction away from, the escapement mechanism and will disengage from the cam member 30a so i that the spring 27 will force the parts into the position of Figure 16 and the foremost peg will gravitate into engagement wlth the finger 29.

As the plate 23 continues to swing in a clockwise direction, the nose 24 will engage with the back of the peg previously fed and 7, force it along the horizontal portion of the track until it engages with the stoprbar .31

and the stop plate 32. These parts illustrated in 17 have notched forward edges" so that as the nose 24 forces the peg forwardly, said peg will ,cometo rest'in a position shown in Fig. 17 with the respective portions of the peg bearing against the semicircular notches indicated in this figure. This will hold the peg upright but as the peg leaves the end of the track it will drop slightly until the flange 33 of the peg engages with the upper faces of the 'stop bar 31. By this time, however, thelower end of the peg will have dropped far enough to partially enter the seat 34 in the top of the corresponding wrench.

. In accordance with this invention, asm my prior case, the numberoi pegs desired to be 7 applied to any one row of the particular bar are fed one after the other into cooperation with the respective wrenches and all the pe s are fedbetore any wrench is operated. After this particular set up of pe s is, however,-in

position with respect to the wrenches, all of the wrenches are forced upwardly to screw all of the pegs simultaneously into the bar positioned in cooperative relation to said wrenches.

The means for operating the wrenchesfembodies a wrench'bar 35 which extends transversely of the machine so as to underlie the wrenches. In practice, the wrenches are all secured to this bar in a detachable manner so as to permit of displacement that when the bar is raised and lowered, all the Wrenches are simultaneously operated'so as to apply all the pegs which may have been previously fed thereto. I

Extending transversely across the machine is a shaft 36 and on this shaft are mounted a pluralityv of cams to actuate the bar 35. One of these cams is indicated at 37 and is positioned midway of the length of the shaft. A similar cam may be positioned on each side of the center cam 37 while a closed cam, such as indicated 111 Figure 3, is associated with each end" of the shaft 36. The'purpose of these cams is to apply force at difierent points in the length of the bar so as to more uniformly apply the force to all of the wrenches at once. The purpose ofthe closed cams of Fig.3 is to insure the retraction of the parts after the pegging operation and at the same 7 time to make necessary the completion of the pegging operationfbefore retraction. closed trackcam of Figure 3 is designated generally by the reference character 38 and it has therein a closed track 39 and is also provided with a curved ratchet face 40. All the cams are of course fixed to the shaft 36.

' The ends of the bar 35 are reduced to form a circular trunnion 41 which operates in the closed tracks 39 as shown.

Aflixed to the opposite ends of the shaft 36 is'a U-shaped bail {or operating handle 42 which constitutes oneform of a suitable prime mover. It is shown in its retracted position, in Fig. 1 for example, but it is adapted to be moved to bring about operav tion of the cams in a counter-clockwisedlrection and into a substantially horizontal position, to oscillate theshaft36 through an angle or": approximately 90 degrees. When in the The V position of Figure 1, all of the cams are on 7 their low phases. If, however, the handle is drawn forwardly through approximately 90 degrees, the cams will act upon the wrench bar to force all of the pegs into position with respect to the superimposed bar O, in the same manner as in my prior machine.

It will he noted, however, that as the wrench bar moves upwardly to apply the pegs, it engages with a nose 43 on a link 44. Two of these links are mounted on coaxial fixed pivots 45 and are pivotally secured at their upper ends as at 46 to the stop bar 31 which also carries the stop plate 32, so that when the wrench bar has moved upwardly sufiicient to cause the pegs to extend well into the seats of the wrenches, the stop bar 31 and stop plate 82 will be thrown back out of the way so that the wrenches can continue to elevate and force the pegs into position in the appropriate chain bar C.

After the several swinging plates 23 have been operated, they remain in their forward or operated positions until the wrench bar is elevated to apply the pegs at which time a flange 35a carried by said bar engages with cam surfaces 230 on all of said swinging plates as indicated in Figure 4 and returns all the plates simultaneously into their retracted positions.

As they swing back into such retracted positions, they pass by the cam members 30 because the springs 27 are holding said cam members out of the path of the swinging plates, but as the swinging plates approach and reach their fully retracted positions indicated in Fig. 4, they engage with the cam members 38 and tilt the escapement to permit one peg of each track to go forward into the dotted line position shown.

As the wrench bar therea ter descends, the parts 31 and 32 reassume their original position to receive the next series of pegs and to stop them in correct positions with respect to the wrenches.

The purpose of the ratchet 40 is to assure completion of the peg applying stroke. As shown in Figs. 1 and 3, a-pawl 47 is pivoted. on a boss 48 carried by the side plate 2 which pawl is adapted for cooperation with the ratchet 40. The pawl is provided *ith two notches 49 and 50 with which cooperates a spring pressed plunger 51. lVhen the bandle 42 is drawn forwardly, the pawl will ride idly over the ratchet 40 until the end of the stroke when a lug 52 will engage the pawl and pivot it so as to engage the notch 49 with the plunger 51. This will retract the pawl from the ratchet so that the handle may be returned to its initial position. As it sub stantially reaches its initial position, a pivoted stop 53 will engage with a pin 54 on the pawl 47 and cause the pawl to be swung to engage the notch 50 with the plunger 51 so that on the next forward operating movement of the handle, the pawl will be in cooperative relation with the ratchet. By this varrangement, it will appear that an operating movement of the handle has been started, this movement will not be reversed until completed and this insures a complete application of the pegs at each operation and obviates the possibility of incomplete pegging of the chain.

In order to facilitate the operation of the keys for the selective feed of. the pegs, I preferably associat with the machine an automatic device for disclosing to the operator the keys which should be operated for each particular set up in order to produce the predetermined weave design.

This mechanism is shown best in Figs. 1, 11, 12 and 13. It embodies a roll 55 with which is associated a guide 56 so that a strip of paper constituting a chart 5'1" may be fed about the roll with step by step movement. On this strip of paper or chart are transverse lines or rows of characters and ti roll is covered by a suitable housing 58 having therein a slot 59 through which one row of characters may be seen at a time. To one end of the roll is secured a ratchet wheel 60 with which cooperates a pawl 61 which extends rearwardly through the machine and is see red to an actuating member This member is in the form of a bell era k pivoted at 63 to a fixed pivot. The bell crank is shaped to straddle the wrench bar C-au see l3) and has a finger 64 which extends into a depre 'on in the rear end of the par 61. Every time the wrench bar 35 elevated, it draws the pawl (31v back and every time that the bar 35 is lowered, it forces the pawl 61 forward, so that by this operation, the pawl acts upon the ratchet to advance the latter as required for either single or double harness chains, depending on whether a relatively deep or shallow pawl nose is connected at the joint 70.

Thus in practice the operator looks through the slot 39 and by reference to the line of the chart which is visible therethrough ascertains what k ys are to be operated. After operation of such keys, the handle 42 is actuated to insert the pegs which have been fed by the operation of the keys and simultaneously with the operation of the handle, the chart is advanced to the next line which corresponds to the next chain bar. Proper feed of the chart is insured by means of a pressure roll 65 which has a relatively narrow pressure band (36. The roll 65 rotates on the pin 67 carried by a bracket pivoted at 68 and spring pressed at 69 to cause the part 66 to hold the chart in frictional driving relation with the roll 55.

The pawl is preferably jointed as indicated at 70 to permit it to be swung hack free from the ratchet 00 while introducing the chart and adjusting the same to proper position with reference to the slot 59.

I have hereinbefore stated that a chain of bars is fed to the roll 5 and thereafter to the peg removing mechanism 16 before being fed to the roll 1. This peg removing mechanism is best shown in Figs.'5, 6, 7 and 18.

, Formed in the upper portion of each of the side plates 2 and 3 are two sets of guide;

ways designated 71 and 72. At the forward ends ,ofthe guide ways 71 is a fixed holder 7 3, the structure of which is illustrated in Fig. 18. The holder is provided at its forward iacewith a transverse channel extending for substantially the entire width of the machine between the side plates 2 and 3, and this channel designated 74 is shaped to form a seat into which the bars are received in succession. The channel is shaped so that the bars will seat snugly therein with the peg holes of the bars in alinement with the plunger bar 77 and extend through holes in the operating bar 78 and thence extend into and are guided by the holes in the stationary guide 73, so that when the cross head is operated by means presently to be dscribed, so as to traverse the guideways 71, the plungers 76 will move from the position of Fig.5 to the position of Fig. 6'and vice versa. The purpose of the plungers is to force the pegs from a bar positioned in the channel or seat 7 4 and in the operation of the machine this is accomplished by the bar 81 which :re-

ciprocates after the manner of a cross head in the guideways 72. The bar 81 is shown in.

detail in Fig. 7. It is illustrated as having therein a slot 82 through which the pegs may be discharged from the chain bars. In practice, the parts are so operated that the bar 81 moves from its normal retracted position of Fig. 4 in a rearward direction to force a juxtaposed chain bar into the seat 7 4 shown in Fig. 18. and the plunger cross head then moves forwardly td drive the 'plungers 7 6 through the holes and force the pegs from the chain bar so. that they are discharged through the slot 82 and are guided bysuitable apron (not shown) directly back of the hopper 17. 'The plunger bar 79 is so arranged as to be readily removablefrom the plunger cross head to permit of substitution of bars as occasion may require.

For example, when operating with a double harness chain a plunger bar having two rows of plungers would be inserted in the cross head, whereas whena single harness cha n is used, a plungerbar wlth a single row enter between the teeth of plungers should be used. In practice, the

arrangement is such that these bars may be readily substituted as occasion may require and when in position will serve to force out all of the pegs from'the barG while the latter is held tightlyto the seat 7 i. After the pegs have been removedtrom any particular bar C, the cleared bar moves on one step and anotherv bar 0 with the pegs therein comes into position for removal whereupon the operationsdescribed are repeated.

.The mechanism for moving the part 81 and theplungercross head is as follows. The part 81 is provided. at its opposite ends with trunnions 88 which extend beyond the outer faces otthe plates 2 and, land engage with cam slots 84in cam plates 85 pivoted to oscillate about trunnions 86, which are carried by the end of the bar 7 3, as shown in Fig. 18. I

The'plunger bar is similarly provided at its opposite end with trunnions 87 which extend into cam slots 88 in the cam plates 85. The cam plates are connected by means of links 89 to operating arms 90 rigid with the shaft 36 as shown in Figure 1. Thus when the handle 42 is pulled down on its operating stroke to force the wrenches upward and apply a row of pegs to a chain bar supported by the lower cylinder, the links 89will bring about rotation of the cam plates 85 from the 7 normal position shown in Fig. 1 to the opposite terminal positions shown in Fig. 2. The cam slots 84 and 88 are so shaped that during this operation the two upper cross headswill be brought together to bring about the ejection of the pegs as described.

As the handle 42 is returned to its normal position, the links 89 will bring about a re versal of rotation of the cam plates 85 and as thisoperation proceeds the following opera tions take place.

A pin 91 on one of the cam plates 85 will engage with the lower end 01" a feed lever 92 which is pivoted on the'end of one of the trunnions of the upper cylinder. The upper end of this feed lever has a laterally extending finger 93 which engages with a ratchet wheel 91 substantially the same as the ratchet wheel 12 and fixed to the end of the upper roll 50 that continued movement of the pin 91 will swing the operating lever 92 and advance the upper roll one step. Simultaneously with this operation, a pawl 95 pivoted at 96 to the plate 85 is lowered from the position of Fig. 2 until the nose 97 of the pawl engages the nose 98 of agravity latch 99. As the pawl descends it operates the gravity latch 99 into the dotted line position shown in Fig. 1 and permitsthe nose 97 of the pawl to of the ratchet wheel 12. i

Upon continued movement of the plate 85,

the pin 100 comes to the end of the slot 101,

so ,thatas the plate continuestorotate the pawl imparts rotary movement to the ratchet 12 to advance this ratchet one step, but it will be noted that the nose 97 holds the gravity latch free from engagement with the ratchet 12 long enough to permit movement of the pawl before gravity again causes the latch to move into a posit n to enga,.;e with the next tooth and positively control the extent of the operating movement of the lower roll.

During the next operation of the handle, the upward movement of the links 89 causes one of them to engage with the lower Weighted end of the pawl lever 92 and swings said pawl lever in a clockwise direction. The pivotal connection of the lever 93 is provided by an elongated slot 102 and this allows the lever to rise during its retrograde movement sufiiciently to rise over one tooth of the ratchet 94 until it comes to the next space where gravity again causes the extension 93 to engage with the next tooth and upon subsequent clockwise movement of the plate 95, the operations described are repeated.

In the manner described, a chain of bars is passed over the upper roll, thence to the peg removing mechanism, thence to the pegging mechanism and thence out of the machine. During the passage of the bar chain, it is advanced step by step through the various operations which I have described, and the operating lever 9 serves to adjust the lower roll 4 as may be desired to insure proper alinement between the holes of the bar and the peg wrenches, so as to provide for the pegging of bars C appropriately to either single or double harness. Provision is made for the use of chain bars of different standard lengths for as shown in Fig. 10, I provide filler pieces 103, each of which is provided at its back with a headed projection 104. The filler pieces 103 have tapered sides to correspond to the taper of the channels 15 and the ends of the bars C and the headed projection 104 are adapted to cooperate with any one of a series of ke hole slots 105 formed in the base of each 0 the channels 1 1 and 15 to control the effective length of the corresponding channel.

These filler pieces may be easily slipped into position or removed and thus provide for the movement of the machine to act upon bars C of different standard lengths.

It will be apparent from the foregoing detailed description of the preferred form of the invention which I have disclosed that the machine embodies numerous features important in the art to which it pertains. It provides simple and effective mechanism whereby loom chains after use can be fed to the machine, the old pegs removed and new pegs inserted in any predetermined combinations dependent upon the will of the operator and during these operations, the operator may have before him an automatically operable chart to guide him in his operation of the machine. The mechanism eliminates a very appreciable amount of tiresome labor and accomplishes the results for which it is intended in a thoroughly trustworthy and eflicient manner. Moreover, the pegging is uniform, each peg being inserted to exactly the same extent as every other peg, thus imparting to the chain a uniformity which it is impossible to obtain in a manually pegged chain.

The drawings illustrate the invention in its preferred, practical form, but the invention is to be understood as fully commensurate with the appended claims.
