SEWING-MACHlNE FOR LACING TOGETHER JACQUARD CARDS.

SPECIFICATION forming part of Letters Patent No. 534,722, dated February 26, 1895. Application filed May 4, 1893. Serial No. 473,085. (No model.) Patented in England February 8, 1890, NmZ

To all whom it may concern:

Be it known that'we, ROBERT REID and JOHN FISHER, residing at Dunferniline, in the county of Fife, Scotland, and JOSEPH PARK- INSON, residing at Bradford, in the county of York,England, subjects of the Queen of Great Britain and Ireland, have invented certain Improvements in and Relating to Machines for Lacing or Connecting Together Jacquard Cards, (for which we have obtained Letters Patent in Great Britain, No. 2,096, dated February 8, 1890,) of which the following is a specification.

This invention has reference to improvements in machines for lacing or connecting together Jacquard cards, and comprises new constructions or arrangements and combinations of several of the component parts of the mechanism with a view to simplify the construction and cheapen the cost of the machine; also making it more applicable for'general use in the class of work for which it is required.

In the accompanying drawings Figures 1 and 2 represent respectively a front elevation and plan of our improved machine. Fig. 3 is an end elevation, and Figs. 4, 5, 6, 7 and 8 views of details hereinafter referred to.

The operating mechanism is carried on two main vertical side frames A, A, secured together by longitudinal stays a, a. Three needles B are mounted in a vertical reciprocating frame consisting of two parallel rods b, b, fitted to slide through guide holes at a in the two upper front longitudinal stay bars a, and secured near their upper ends is a horizontal bar 0, whose ends are connected by rods 0, c, and levers c, c, to the rocking shaft 0 which is operated through the lever c and rod 0 by a cam on the first motion cam shaft D. A horizontal bar E is mounted at the lower end of and between the said vertical rods b, b, of the needle frame, and to which are attached the needle holders e of each needle B, in the position desired.

As seen more particularly in Figs. 4 and 5, each needle B. is-carried through a vertical slot or hole in the adjustable holder e,and is secured therein by pinching screws e These needle holders e embrace the horizontal bar E, and are secured in the required position thereon by the respective screws and levers e The presser feet g for holding down the cards while being laced, are of curved shape and partly surround the needles B. Each of these feet is mounted by an eye at its upper end on the spindle or bar G, which has a bell crank arm g'with a tension spring g at its upper end to keep each foot 9 pressing the cards down on the supporting bed plate or shuttle race. A blade spring G is or may be provided to hold the cards down on to the chains while approaching and passing under the lacing mechanism.

The shuttles and shuttle carriers, shown by details Figs. 6, 7 and 8 are mounted parallel with each other to reciprocate transversely of the machine and horizontallyunder the cards being laced. The shuttles H with their carriers H are fitted in slide guides H which are adjustable on end stays h and are fixed thereto by set screws 71/ in any desired position to suit the lengths of cards.

Each shuttle carrier H, is mounted in its carrying slide H and each is fitted in front with a removable cover I hinged at '5, and adapted to be locked in position by the horizontal arm of a spring pressed bell crank lever z" engaging a catch 4?, formed on the front of the carrier H, which is also provided with a driving slot below, for engaging with the vertical web j of an angle iron bar J, carried by bosses 7' at its ends, said bosses being bored to slide on guide rods 70, secured in brackets is on the inside of each side frame A. This angle iron bar J, is reciprocated by connecting rods L having their inner ends attached to the bosses 7' of the angle bar J, and their outer ends centered on crank pins on the sides of revolving spur wheelsl carried on stud spindles Z at the back end of the frame A. The wheels Z receive their motion from wheels D on the main cam shaft D of the machine.

In order to prevent the'chain wheels Q, slipping, a plain surface wheel or pulley is provided and fitted with a friction brake m, mounted on the upper end of the vertical arm m of the bell crank lever m m and is pressed against the pulley M by a spring m fitted behind. The other arm m of bell crank lever is actuated by a roller or pulley from the segmental cam m on the feed tapped cam shaft N, the friction brake block m, stopping the motion of the wheels on the chain shaft Q, while the pawl O is slipping over its teeth on ratchet wheel 0' and the sewin g taking place,

the said friction block m, being moved out of grip with the pulley M when the pawl O is moving the chain wheels and chains forward with the cards.

The feed pawl lever O is operated by short tappets or segments 9, with curved outer surfaces provided, and have inner projecting stems, which pass between guide slides formed on the side of cam wheel P, and are secured by screws. By this means, any size or length of projecting curved tappets or segments can be used to suit the motion required. Both the feed tappet cam P and the friction brake actuating cam m are mounted on the shaft N outside the framing A, of the machine, to facilitate the changing of the tappets or segments p.

The back shaft Q, on which the chain driving wheels Q are secured, is mounted on quadrant arms (1 on each side frame A of the machine, the said arms being adjustable so as to permit the said shaft being raised or lowered to any position. Hinged levers or arms R (see Fig. 8) are mounted below the front chain shaft S with a pulley r, at the end of each resting upon the card carrying chains T, by which the necessary amount of tension is given to the same.

The starting and stopping of the mechanism are effected by mounting fast and loose pulleys W and W side by side on a stud spindle w, mounted in bearing brackets in the side frames A of the machine, the driving belt being shifted from the loose to the fast pulley and vice versa, when starting and stopping the machine, by a belt fork W secured on spindle w below. This spindle has a lever 11; projecting downward and connected by a link 2.0 to a lever 10 on a rocking bar w upon which is fixed a double tread lever 00 in front, to be operated by the foot of the attendant to shift the driving belt.

A spur wheel 1 on the spindle w gears with and actuates a spur wheel D on the first or main driving cam shaft D of the machine, which through levers and connecting rods actuates the needle frame above. A pinion 2 on the main driving shaft D gears with and actuates a wheel 3 on the shaft N on which the tappet cams m are mounted. The chain driving wheels Q can be shifted longitudinally along the shafts Q and fixed thereon to suit the position of the shuttles and the sizes of the cards to be laced.

The thread is wound on the shuttle spools by mechanism mounted on an oscillating frame bracket 4, over the driving pulleys W, W at the side of the machine frame A. This is effected by a spur wheel 5 on the end of a stud spindle 6, on which a pulley or roller '7 is mounted near the center of the bracket frame 4, which is centered to oscillate on spinanother spur wheel 9 mounted on a stud spindle 10, in the bracket frame 4, and the spool of each shuttle is inserted between a notch in the end of this spindle 10, and a notch in an outer overhung projecting bearing 11, so that the thread is wound onto the spool when the roller 7 is depressed and the thread being guided by a hand lever 12 centered on a vertical screw. stud B near its center.

The balls of thread 14 for supplying the needles, are placed in trough 15 and conducted therefrom between the two bars 16 held together by elastic bands 1.7, of such strength as will admit of the thread being drawn as re quired for each card. After leaving bars 16 it passes round the respective tension springs 18 of the usual construction, andthen through an opening in end of levers U to the needles B in the direction indicated by the arrows and dotted lines.

What we claim as our invention is- 1. In a machine for lacing Jacquard cards, the combination of needle and shuttle mechanism and means for adjusting the said mechanisms for different sized cards, with a shaft provided with chain wheels adjustable along the shaft, a rotating wheel provided with removable tappets and connections whereby the said shaft is actuated by the said tappets, substantially as and for the purpose set forth.
