BLOOM.

Application filed May 2, 1912, Serial No. 694,793.

To all whom it may concern Be it known that l, JOHN M. HQLLADAY, a citizen of the United States, residing at Holladay, in the county of Spottsylvania and State of Virginia, have invented certain improvements in Looms, of which the following is a full and complete specification.

My invention relates more especially to that particular class which is commonly known as the Jacquard loom.

In the construction of the prevailing type of Jacquard loom it is customary to em ploy pattern-cards laced together in the form of a chain, and by means of a cylinder or drum bring said cards successively in operative position with respect to the needles; but in practice this form of pattern-mechanism is not entirely satisfactory, inasmuch as the means employed for handling or feeding the chain of laced cards is so cumbersome or unwieldy as to result in considerable wear on the cards and lacing strings requiring frequent repairs and consequent interruptions in the operation of the loom. Furthermore, this means of handling the pattern-cards requires considerable space at one side of the loom, and the chain of laced cards extending to and from the cylinder or drum obstructs the light to the loom.

The primary object of my present inventi on, therefore, is to provide a patternaneclr anism for Jacquard looms in which the lacing together of the pattern-cards may be dispensed with and said cards fed separately and successively into operative positi on with respect to the needles and movable block in such manner as to not only insure a. regular and positive operation but also maintain an entire set of pattern-cards in c ose com act form immed ately adjoining the mo able b ock and needles to save space and admit light to the loom.

A further obiect of my invention is to provide a natte n-mechanism of such con struction that the pattern-cards are at all times kept in regular order and fed seriatz'm, so that a series or set of cards may be repeatedly passed through the loom for the purpose of duplicating any particular pattern.

Other obiects and advantages of the in vention will hereinafter appear, and what I claim as my invention, and desire to protect by Letters-Patent is more specifically set forth in the appended claims.

In the accompanying drawings, which Patented Feb. 116, i915.

Renewed July 24:, 1914. Serial No. 852,936.

form part of this specification: Figure 1 is a side elevation of a pattern-mechanism for Jacquard looms, in accordance with my invention. Fig. 2 is a plan view, showing the arrangement of boxes in series. Fig. 3 is a rear end view of the connected cardboxes shown in Fig. 1. Fig. i is a detail transverse sectional View through one of the card-boxes, showing one form of bottom therefor. Fig. 5 is a side elevation i1lustrating a modification of the invention. Fig. 6 is a plan view of a portion of the bottom of one of the card-boxes used in connection with the construction shown in Fig. Fig. 7 is a front elevation of the 1nechanism used in Fig. 5 for pushing the patterncards into operative position. ig. 8 is a detail sectional view of one of the blocks for moving the pattern-cards toward the needles.

Like numerals of reference indicate like parts in all the figures of the drawings.

In carrying out my invention 1 provide for each bank of needles two boxes of suitable length in which an entire set of pattern-cards for any particular pattern are placed in regular order, so that the first card of the series may be fed from the front of one of the boxes and after service in operating the needles deposited in the other 1302; behind the last card of the series, and a card simultaneously deposited from the receiving box into the feeding box at the other end of the device; whereby all the cards in both boxes may be fed to the needles sericzfm, through the instrumentality of the mechanism hereinafter described, and the operation repeated for the purpose of hiplicating the pattern.

In the present instance I employ a later ally movable block 10, in place of the cylinder or drum commonly used in connection with that form of pattern-mechanism for Jacquard looms in which the pattern-cards are laced together, the required lateral motion being imparted to this block by means of the usual horizontal reciprocating rods 11. This block moves to and from the needles 12 supported in the plate 13, and in order to properly support the pattern-card during this operation it is firmly gripped at its opposite edges between spring-actuated metal straps or yokes 14- and 15 carried by the block 10 and plate 18., respectively, said metal straps or yoltcs being pressed yieldingly toward each other by compression springs 14 and 15 respectively. It will be understood that these metal straps or yokes have a limited movement toward each other when the block is in the normal position shown in Fig. 1, so that a slight space is left between them to receive the patterncard, and it will be further understood that upon the initial forward movement of the block the metal straps or yokes 1-t first yield so that the registering-pins 16 carried by the block may enter the registeringholes a in the pattern-card a to insure the proper position of the latter with respect to the needles upon which it operates. In the present instance the registering-pins 16 are each seated in a recess 10 in the block and engaged by a spring 17 (Fig. 8), so that in case the pin fails to properly strike thehole it will give and not tear the card. The operation of this block and cooperating pattern-card is practically the same as in the prevailing type of Jacquard loom; that is to say, those needles which are opposite corresponding holes in the card remain stationary during the movement of the block while those opposite blank places of the card are moved; but in the present instance separate patternvcards are used and fed into operative position successively, and though I have herein shown two forms of mechanism for the purpose it will be readily seen that the construction and arrangement of operating parts may be changed within the scope of my invention.

Referring now to Fig. 1, the forward end of the feeding card-box 17 is located immediately below the space between the metal straps or yolres let and 15 between which the pattern-cards are received, and in. this in tance said card-box is inclined downwardly from its rear end, so that the bulk of cards therein may be easily moved forward after each card is pushed into operative position with respect to the block and the pusher, hereinafter referred to, is lowered. To further facilitate the movement of the cards in the box, and also reduce friction and consequent wear, on the lower "edges of the cards, the bottom of the box 17 is provided with longitudinal flat ribs or ridges 17 After each pattern-card is operated by means of the movable block 10, as hereinbefore described, it is received in the forward end of the receiving cardbox 18, located above the block and inclined downwardly therefrom, resting at its rear end upon the rear end of the feeding-box 17, so that the cards will pass down the in clined bottom of the receiving box and deposited in the rear of the receiving-box, it being understood that both boxes are filled with pattern-cards with the first card at the forward end of the feeding card-box and the last card at the forward end of the reeeiving card-box, those cards in the feedingbox being fed out at the forward end thereof and those in the receiving-box following them by being fed from the rear end of the receiving-box into the rear end of the feedmg-box. The receiving-box is likewise provided with longitudinal ribs or ridges l8, alternating with the ribs or ridges 17 of the card-box 17, so as to evenly distribute any wear on the lower edges of the cards,

as will be understood. The boxes 17 and r ing vertically through the bottom of the forward end of the feeding card-box, said pusher-plate being connected for operation to the forward end of a horizontal bar or lever 23, pivoted at the upper end of the post or upright 20, and extended rearward therefrom to operate the device for transferring the cards from the receiving cardbox to the feeding card-box, and this rocking-bar or lever is operated from the reciprocating rod 11 by means of a vertical arm 24 attached to said rod and connected by a link 25 to a lug 26 on the rocking-bar or lever above its pivot. Therefore, on the rearward movement of the reciprocating rod 11 the forward end of the rocking-arm or lever 23 will swing upward carrying with it the pusher-plate 22, which latter shoves the pattern-card up into proper position between the metal straps or yokes 1+ and 15, suitable guides being provided at opposite ends of the block to guide the card, and flat springs 27 are seated in the guides to hold the card after the pusher-plate is lowered and before the registering-pins 16 on the block engage the card. After service of the pattern-card in governing the operation of the needles 12 it is pushed up into the forward end of the receiving card-box 18 by the next pattern-card pushed up by the pusher-plate 22, and in order to make room for the second and subsequent cards in the receiving card-box I provide a spring plunger 28 for moving all the cards rcarward in said receiving-box after each card is pushed into the forward end thereof. The plunger is operated by a yoke 29 connected thereto and to a crank-arm 30 pivoted to the outer end of the supporting bracket-arm 21, the crank-arm being operated by a pin 31 projecting from the reciprocating rod 11. The plunger 28 is boxshape, with a surrounding flange 82 at its outer end, the springs 33 for projecting the plunger being interposed between said flange and the front end of the receivingbox. The movement of the plunger is sufficient to push the bulk of cards in the receiving box a distance equal to a little more than the thickness of each card, and in order to hold that card pushed by the plunger when the latter is retracted, and thereby leave a space between said card and the plunger in which the next card may be pushed upon the operation of the pusher-plate 22, a suitable number of catch-springs 3% are provided, said springs being attached to the walls of the box with the catch-ends projecting through openings therefor in said walls, as shown in Fig. 1. In the present instance two catches are located at each side of the box and one at the center of the top so as to firmly engage and hold the cards against expansion when the plunger is retracted. Similar catch-springs, as 35, are located at the rear end of the receiving-box, so that a single card may be pushed from the receiving-box into the feeding-box without interference by the other cards.

The cards are pushed from the rear end of the receiving-box 18 into the feeding-box 17, below, by means of a pusher-plate 36, carried by bracket-arms 37 hingedly connected to a presser-bar 38, and held yieldingly thereon by a spring 38*, said presserbar being carried by a shaft 39 operated by the rear end of the rocking-bar or lever 23. The connection between the rocking-bar or lever and shaft 39 is by a sliding guideframe comprising the upper cross-head 4 through which the shaft passes, and vertical guide-rods ll, 41, slidable in suitable sleeves 41-2 let into the side frame 19, the rocking-bar or lever 23 being connected to the cross-head of the sliding guide-frame by means of a link 43. The shaft is adjustable longitudinally in the guide-frame cross-head and se cured after adjustment by means of setscrews 44, and likewise the depending presser bar 38 is adjustable on the shaft and held by set-screws 45; these adjustments being provided to accommodate card-boxes of different lengths, according to the number of cards used for a pattern. To accommodate the vertical reciprocating movement of the pusher-plate 36 the rear end wall of the receiving card-box 18 is provided with vertical slots 46 (Fig. 3), through which the bracket-arms carried by the presser-bars work, and of course the bottom of the box at this point is provided with a transverse slit, through which the card passes into the feeding card-box through a similar slit, in

the top or cover of the latter, these slits being similar to those indicated by the numerals 47 and 48 in Fig. 5.

In order to push the bulk of cards forward in the feeding card-box, to receive the cards seriatz'm from the receiving card-box, there is a plunger 50 in the rear end of said feeding card-box having rearwardly-projecting ears 51 to which is connected one end of a bell-crank lever 52, supported in a suitable bracket 54, the other end of said bell-crank lever being operated by the presser-bars 38, for which purpose each of the latter is provided with a presser-foot 55 having an engaging set-screw 56 for regulating the throw of the bell-crank lever. 'lhe plunger is retracted by means of'a spring 57 interposed between the depending member of the bellcrank lever and rear of the feeding cardboX, and as will be noted by reference to Fig. 3 the upper member of the bellcrank lever is extended laterally for engagement of the set-screws carried by the presser-bars 38. To hold the cards in the feeding cardbox after the operation of the plunger 50 the rear end of said box is provided with catchsprings 58, similar to the catch-springs 3i and 35, hereinbefore referred to, and similar catch-springs, as 59, are located at the forward end of the feeding card-box to relieve the pressure against the card which is pushed up into operative position by the pusher-plate 22.

From the foregoing description of the construction of the pattern mechanism shown in Fig. 1, it will be seen that in operation the pattern-cards are removed serz'atim from the feedingbox and fed into operative position in front of the movable block 10, a pattern-card being fed upon each rearward movement of the reciprocating bar 11, and upon the forward movement of said bar, to govern the operation of the needles through the medium of the pattern-card, the pin 31 strikes the arm 30, which pulls back the yoke 29 and operates the plunger 28 so as to make room in the forward end of the receivingbox for this patterncard. Now as the bar 11. again moves forward, feeding the next pattern-card into operative position, the one in advance, or first pattern-card, is forced into the receiving-box, and simultaneously a' pattern-card in the rear end of the receiving-box is pushed down into the feeding-box by means of the pusher-plate 36, the lowermost stroke of the presser-bars 38 during this operation actuating the plunger 50 to move all the cards forward in the receivingboX. In thismanner the cards are fed seriatz'm and continuously from one box to the other in regular order, and, as will be noted, when the last card of a pattern reaches the forward end of the feeding-box the first pattern-card follows, so that a pattern may be repeated as many times as desired.

This pattern mechanism provides for feeding the cards separately to the patternblock, and also provides for keeping them in regular order and free from dust and dirt, inasmuch as in practice the card- boxes 17 and 18 will have suitable tops or covers, and

the cards are protected during their passage from one box to the other.

The length of the card- boxes 17 and 18 will depend upon the number of patter-1r cards used for a pattern, and when longer or shorter boxes are used the shaft 39 is adjusted to bring the presser-bars 38 and parts carried thereby, in'proper position with respect to the rear ends of the boxes, the forward ends of said boxes being properly positioned above and below the movable patternblock. I

Inasmuch as my invention consists broadly in feeding the pattern-cards of a loom separately to the pattern-block and in such manner as to maintain them at all times in regular compact order I have shown a modification of the apparatus for accomplishing this, such modification being illustrated in Fi gs. 5, 6, and 7, which I shall now describe. In this modification the feeding and receiving card-boxes 60 and 61, respectively, are disposed horizontally, and in order to prevent friction in moving the bulk of cards the bottom of each box is provided With a continuous belt 62 moving loosely over rollers 63 journaled in cross-bars (it of the supporting-frame 65, and to prevent sagging of the upper part of the belt between the rollers, thereby insuring a direct feeding of the cards, there are longitudinal strips 66 immediately below said upper part of the belt and seated in peripheral grooves 67 in the rollers (see Fig. 6), said strips being supported at suitable intervals by crossbars 68 attached to the bars G-L of the supporting-frame. The same construction of movable pattern-block and cooperating parts for actuating the pattern-cards to and from the needles is used in this modification as in the form of apparatus hereinbefore described, and therefore further description of the same is unnecessary, the same reference numerals being used. In this instance each pusher-plate, as 69, for moving the pattern-cards seriatz'm from each receiving-card-box 60 to the pattern-block is connected by a rod 70 to a crossbar 71 attached at its ends to operating-barsTQ at the sides of the supporting-frame, said operatingbars being disposed horizontally and guided in vertical movement by guide-rods 73 at opposite ends of the frame on which sleeves 7st carried by the horizontal operating-rods or bars slide. The pusher-plates are adjustably connected to the cross-bars 71 by means of set-screws 75 threaded on the connectingrods 70 above and below said bar, so that the upward movement of each pusher-plate may be accurately adjusted to move each pattern-card into exact position with respect to the block and registering-pins 16 carried thereby. The operating-bar 73 is reciprocated vertically by means of a bellcrank lever 76, pivoted in a supportingbracket 77 attached to the frame, one end of the lever being connected to a pin 78 projecting from a lug 79 on said 0 )erating-bar, and the other end of the lever connected to the lower end of a vertical arm 80 carried by the reciprocating-rod 11, and in order that this depending-arm 80 may also operate the plunger, as 81, in the rear end of the receiving card-box 60, it is connected to the outer end of a rod 82 projecting from said plunger, an interposed helical spring 83 being employed to impart a yielding movement. The cards are moved from the rear end of the receiving-box 61 into the rear end of the feeding-box 60 by means of rods 8i adjustably secured by winged nuts 85 to a cross-bar 86 extending between the rear ends of the operating-bars 72, said rods S-L having fingers 8? which engage the upper edge of the card and work in slots 88 in the end of the box 61. As the receiving card-box and feeding card-box are spaced apart the cards are guided from one to the other by means of the guide-plates 89. The rods 84: which push the cards from the rear end of the receiving box toward the rear end of the feeding-box are guided by suitable bracketarms 90 projecting rearward from the frame of the apparatus. In this modification the devices for pushing the cards into the receiving-box as they are fed therein from the pattern-block 10 are similar to those hereinbefore described in connection with the mechanism shown in Fig. 1; that is to say comprise a box-like plunger 91, operated by a yoke 9.2 connected to a. crank-arm 93, the latter being pivoted to the supporting frame with its free end in the path of a pin 9i projecting from the reciprocating-bar 11. It will be noted, also, that the cardboxes 60 and 61 are both provided at their ends with spring-catches, as 95, for holding the cards after they are pushed in the boxes by the plungers. The operation of the mechanical devices shown in the modification, and just described, is similar to the operation hereinbefore described in connection with the form shown in Fig. l, and therefore obvious.

Though I have shown and described the card-boxes as located above and below the reciprocating pattern-block which moves said cards toward the needles, it will be understood, of course that some other arrangement may be resorted to within the scope of my invention. However, by locating the card-boxes in vertical line it permits of several pairs being arranged side by side and accommodate the horizontal series or banks of needles employed in the prevailing type of Jacquard loom.
