LOOM-CABD-IEGGEING MACHINE.

Application filed March 22, 19-22. Serial No. 5455,7194.

To all whom it may concern:

Be it known that I, Fnno UTTLEY, a citizen of the United States, residing at Elinhurst, in the county of Queens and State of New York, have invented a certain new and useful Loom-Cardlegging Machine, of whicn the following is a specification.

This invention is :a machine for pegging loom cards and more particularly a machine for accomplishing this purpose in an expeditious and accurate .manner. It is well understood by those skilled in the art to which the present invention pertains that the pegging of the loom cards must be changed to eifect changes in design and for any particular design a particular set up or arrangement of the pegs on the card must be provided. I The cards usually employed are of wood and are provided longitudinally with two rows of openings or holes into which the pegs may be screwed, the particular holes into which the pegs are screwed serving to control the design desired when such a card is subsequently used in the loom. The pegs used are of metal and are provided intermediate their ends with a shoulder or flange. That portion of the peg between the flange and one end of the peg is generally threaded with, for example, a four to one thread while the opposite side of the flange is polygonal to receive a wrench by means of which the pegs may be screwed into the holes of the card. The wrench exclusively employed at the present time is a socket wrench provided at one end with a handle adapted to be held in the palm of the operators hand and manually manipulated to screw the pegs into the holes of the card individually. That is to say, under the present practice, the workman picks up one peg at a time, introduces it into the end of the wrench and thereupon screws the peg into position on the card. This practice is tedious, requires considerable time and also necessitates the employment of skilled workmen of long experience to accurately position'the pins or pegs on the cards in the manual manner described.

lVith the foregoing considerations in mind the'object of the present invention is to provide a machine which will, in eifect, automatically mount the pegs on the cards, and which may so operate as to simultaneously mount a large number of these pegs on a card at one operation.

hoards. By the employment of the present invention the p egsmay be appliedto a card panying drawings.

22 :of Figure 1.,

llVhile the present invention may, partake I of different practical forms it may, "to advantage, embody means for holding a loom card in position to receive the pegs "adapted to be associated therewith, means for se lectively feeding a plurality of pegs into position to be applied, and means for simultaneously forcing a plurality of suchpegs into predetermined, proper positions on the with ease, accuracy and dispatch, thereby minimizing on time consumption and ehrninating errors which frequently occurunder the manual operation hereinbefore referred to. v

Features of the invention, other than those adverted to, willbe apparent from the hereinafter detailed description and claims, when read in con The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not defining the limits ofthe invention.

Figure 1 is a plan view of a machine embodying the present invention, shown partly in section in the interest of clearness. w v

Figure 5 is a section corresponding to the sectioned part of Figure l but showing the parts shifted into diiferent positions.

Figure 6 is a fragmentary section illus trating the operation of certain peg feeding means shown in Figure 2, and v Figure 7 is a fragmentary perspective View of one end of a conventional form of loom card. v

In the. accompanying drawings JL have illustrated the machine in a more or less diagrammatic way in order that the opera tions thereof may be clearly understood; In this showing 1 designates any suitable support such, for example, as a bench or table top. On this support 1 is fixed a frame 2. In the upper portion of the frame a carrier roll or conveyor?) is mounted for junction with the accom- .1

the roll will be shifted in a radial direction the same distance as the roll is shifted longitudinally. The purpose of this shifting will be hereinafter more fully described and such shifting may be accomplished in any suitable way, but for purposes of illustration I have shown one of the bearings a as provided with a projection having therein slots 8, with which slots a bifurcated lever is adapted to engage and through the action of this lever, operated in any suitable way, the roll may be shifted longitudinally and, simultaneously, radially.

The roll, which constitutes the carrier for the cards to which the pegs are to be applied, is provided in its outer circumference, with depressions or recesses in the form of pockets 9 so shaped as to form a seat for, and receive therein, a plurality of loom cards, a portion of one of which is shown in Figure 7. The pockets 9 are preferably spaced equidistant about the circumference of the roll as shown in Figure 2 and each pocket is shaped so that one card is adapted to fit into each pocket. In practice, the cards may be linked or chained together in the manner in which they are used on the loom and thereafter fed into the pockets in succession as the carrier roll 3 is revolved, or they may be positioned in the pockets in any suitable way and maintained therein in any desirable manner.

The carrier roll 3 serves, in the machine of this invention, as a support for the cards to be operated upon and its function is to hold the cards in succession in a position to receive the pegs which are applied thereto in an automatic manner as hereinbefore more fully described. In order, however, that the roll 3 may be held against rotation while the pegs are being applied to any particular card one of the shafts or spindles which supportsaid roll has preferably fixed thereto some means of accon'iplishing this end. A very simple construction for accomplishing this result is shown in Figure 2 wherein a collar 11, having the same number of flat sides as there are pockets in a roll, is fixed on one of the spindles of said roll and a spring 12 bears against this collar in such manner as to preclude inadvertent ro tation of the roll and to hold it steady while the pegs are being applied.

The pegs are applied by means of a plurality of plunger-s or wrenches In a conventional card there are two rows of peg holes 10 and 10" of twenty-five holes each (see Figure 7) and the holes of these rows are staggered. For operating upon a card of this character, 1 preferably employ twenty-five plungers or wrenches 13 positioned at successive distances apart equal to the distance between centers of the holes in either row. These p-lungers are mounted for vertical reciprocation in the transverse parts 14; of the frame and in such relation to the carrier roll 3 that when the carrier roll is at rest, all the plungers will be coaxial with one row of holes 10 of the superimposed card 10 supported on the carrier roll 8 in a position to be operated upon, as shown in Figure 2. All of the plungers 13 are the same length and their lower ends are adapted to rest at all times upon an operating bar 15 which extends transversely of the machine and underlies the lower ends of the plungers. The operating bar is mounted for vertical movement and is adapted to be so moved by means of one or more cams 16 fixed on a rock shaft 17 which is journaled in the ends of the frame 2. An operating handle 18 is also secured to the rock shaft 17 and by manipulating this operating handle 18 the cams 16 may be shifted for the purpose of causing the raising or lowering of the operating bar 15 to the end that the plunger-s 13 may be moved toward and retracted from the card 10.

Each plunger is provided in its upper end with a socket 13 adapted to receive the shank of a peg. When the handle 18 is operated to elevate the plungers, said plungers will be forced upwardly with the result that any pegs carried by said plunger-s will be forced into the aligned apertures 10 of the superimposed card. It will be noted from Figure 2 that the lower end of each plunger is rounded and, in practice, the plungers themselves are mounted for rotation within the frame parts 14 so that said plungers may freely rotate while forcing the pegs into the holes of the card. After the pegs have been forced into position the handle 18 is raised, thereby permitting the plungers 18 to be retracted by gravity, leaving the pegs in position. The weight of the handle 18 may. if desired, be counterbalanced in any suitable way as by a spring 18.

In the manner described, the handle 18 may be operated for applying a plurality of pegs simultaneously to the holes 10* of the card. It will be apparent, moreover, that if the carrier roll 3 is shifted longitudinally in its 45 degree angular bearings the card 10 will be bodily shifted to a position wherein the apertures or holes 10 in the card will go into alignment with the respective plnngers. In this way the pegs may be applied first to the holes 10 and the carrier roll 3 then shifted, whereupon the pegs may be introduced into the holes 10". By this construc-v tion, I am able to peg fifty holes through the use of twenty-five wrenches.

It will be apparent from what has been said that when the plungers are elevated all of them which carry pegs will simultaneously force the pegs in position. Accordingly, the positioning of the pegs in the various holes of the card may readily be controlled by selective feeding of the pegs to only such plungers as it is desired to have effect a pegging operation and, in accordance with this. invention, I have devised novel and efficient means for selectively feeding such pegs to the plungers. While this means, may vary without departing from the broad scope of the present invention, I have shown in the drawings an efiicient method of producing this result.

Thus, in Figure 1, I have shown a hopper 19, mounted on the fixed support 1 forwardly of the frame 2. This hopper is adapted to contain a supply of pegs and, from the hope per, a plurality of tracks lead to the respective plungers. Each track embodies two parallel strips 20 forming between them a guide channel 21 which leads from the hopper to the socket 13 of the corresponding plunger. The tracks, as shown in Figure 2, are inclined so. that such pegs as mount the tracks will gravitate in the direction of the plungers.

The tracks 20 project well into the hopper 19 as shown in Figure 2 and a portion 22 of the bottom of the hopper is made movable and is guided for Vertical movement. The portion 22 is surmounted by a plural ity of upwardly projecting parallel teeth or webs which impart-to the movable portion 22 the shape of a comb, the teeth of which are adapted to extend upwardly between adjacent tracks 20 and the upper edges of which teeth are beveled in lateral directionsand slope rearwardly, as clearly shown in Figures 2 and 4. One end of the comb member 22 is secured by means of a pivoted link 24;. to the handle 18 while the Other end is similarly secured by the link 24 to, an arm 25 which is secured to the rock shaft 17. Accordingly, the movement of the handle 18 will impart vertical movement to the comb member 22 with the result that the comb member will be raised or lowered from the dotted line position of Figure 4 to the full line position of Figure l and vice versa. When the comb member is raised it will elevate such of the pegs as have fallen between the tracks 20 and cause them to be tumbled laterally so that when the comb is depressed certain of these pegs will be left in a position to slide down the inclined tracks. In practice, the screw end of the peg is shorter and lighter than the other end thereof so that the pegs will automatically fall screw end up and will in this position successively slide down the inclined tracks, I have found in practice that the mechanism described will position the pegs on the tracks with unusual elite ciency since the movable bottom portion etl'ects etlicient agitation and manipulation of the pegs to automatically position them delivered from the lower end thereof in positions to fall into the socketslii of the associated plungers It is, essential, however, that the movement Of these pegs be reg? ulated so as to control the feed of pegs t only those p nne which t i desir d to a func a any par icul r Op tion of the machine. While this end may be a plishe in i fer nt Way I preferably associate with the lower end of, each t ck a pa f coop ra ing ed fing rs 2 6 and 27, a portion of each linger being in the form of a rack adapted to mesh with an i te med ate r ge r 2 1 The n rm position of the parts is as" shown in Figure 6v in full lines, wherein the finger 26 is elevated and the finger 27 is depressed. It w l e n r m Figure 6 hat the finger 26 is at this time holding the pegs in restraint. If the finger 27 is now elevated, the idler gear will cause a simultaneous depression of the finger 26 so that the finger 26. will be withdrawn from in front of the first peg w while the finger 27 will be proiected upwardly between the first peg a and the second pegza, after the manner shown in Figure 2, with the result that the first peg 00 will be released by the withw a al of he finge 26 Whi e he fi g r .7 simultaneously restrains the second peg .113. Moreover, as the finger 27 approaches the upper end of its travel it is freed from contact with the finger 26 and immediately engages a stop in the form of an adjustable set screw 27*. As a result of such engagement, the finger 27 is forced quickly forward onto the top of finger- 26. as shown in Figure 2. Through this forward action the first; peg a: will be quickly impelled forward and into, a position wherein it will fall into the socket 13 While the feed fingers 26. and 27 may be operated in different ways, I have found, it highly eflicient to control them from finger keys. Thus, I associate with each finger 27 a lever 29 pivoted at 80 and provided at its forward end with a linger key 31. If the finger key 31 is pressed down the feed linger 27 will he obviously elevated and the finger 2 6 simultaneously depressed so as to fed one peg There are feed fingers 26 and 2'? associated with each track and each pair of cooperating feed fingers are controlled by a linger key. All of these linger keys may be grouped after the manner shown in Figure 1 and may bear suitable identifying numbers, letters or symbols.

It will appear from the foregoing descrip tion, that the pegs to be fed to the respective plungers may be controlled through the manipulation of predetern'iined finger keys 31. That is to say, the finger keys 31 provide means for selectively controlling the feed of pegs to the plungers so that certain plungers may be included while others are excluded. Thus, in order to obtain the desired pegging for any particular set up it is only necessary for the operator to operate the proper keys in order to provide the appropriate wrenches with pegs, whereupon the handle 18 may be forced down to simultaneously apply all of said pegs to the card. It will be noted that after the operation of each key the feed finger 27 asso ciated therewith is left in elevatedposition. However, when the handle 18 is forced down and the operating bar 15 elevated, it will engage all of the fingers 26 which have been depressed and so return all of these depressed fingers into their normal elevated positions, simultaneously depressing the raised lingers 27 and leaving the machine in position to be operated for a new set-up.

An important feature of the present invention resides in the fact that by introduc ing the pegs mechanically and accomplishing this result in such manner as to introduce aplurality of pegs at each operation, the pegging of a card is accomplished much more rapidly than it could possibly be done manually. lvioreover, the positioning of the pegs is absolutely reliable and accurate so that greater speed of operation is not only secured but absolute accuracy. Furthermore, the cards to be operated upon are firmly held in position while the pegs are applied thereto, thereby greatly facilitating the work.

The invention is capable of certain other modifications, as by the substitution of equivalents, without departing from the invention. So far as I am aware, the present invention is the first for mechanically pegging loom cards. It is not possible to show all of the various modifications of which the machine is capable and, accordingly, this invention is to be understood as broadly novel as is commensurate with the appended claims.
