EDWARD WALTON, OF PENRITI-I, VIRGINIA, ASSIGNOR TO WALTON PATENT BARREL COMPANY, INC., OF RICHMOND, VIRGINIA, A CORPORATION OF VIRGINIA.

SLAT-WEAVING MACHINE.

To all whom it may concern:

Be it known that I, EDWARD WVALTON, a citizen of the United States, residing at Penrith, in the county of Cumberland and State of Virginia, have invented a new and useful Slat-WVeaving Machine, of which the following is a specification.

This invention relates to slat weaving machines, and more particularly to improvements in machines of that type set forth in United States Letters Patent No. 618,925, granted to me February 7, 1899.

The invention has for its objects to provide a novel mechanism for feeding the slats automatically to the weaving machine, and further to provide a novel and efficient operating means for the said mechanism and for the lay of the weaving machine, and furthere an. improved means for holding the warp wires, and finally a clutch device for throwing the weaving machine into and out of operation.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

view of the clutch device shown on an enlarged scale. Fig. 13 is a detail view of the elevator of the slat feeding mechanism. Fig. 14 is a fragmentary View of part of the lay+actuating means of the weaving ma chine.

Similar reference characters are employed to designate corresponding parts throughout the views. 1

Referring to the drawings, 1 designates the corner standards of the frame A that are connected together by horizontal side and end beams 2 and 8, respectively, and at the front thereof is a side extension or table designated by B for the slat-feeding mechanism. At the rear of the frame A is mounted the operating mechanism for the various parts of the weaving machine.

Rising from the front part of the frame is a spool rack C provided with horizontal spindles 4 on which are mounted the spools 5 for the warp wires 6, the spools being arranged in pairs, one above the other, and grouped side by side, and the wires extending vertically into the weaving machine.

Under each pair of spools is a tensioning device consisting of rods 7 arranged one above the other and mounted in bearing members 8 secured to cross bars 9 at the base of the spool rack, and the wires are intertwined with the rods so as to provide the desired tension. wardly from the tensioning devices and are passed through heddle bars 10 arranged in pairs to correspond with the runs of the warp wires, and each pair of heddles are connected by links 11 with oppositely disposed arms 12 on a rock shaft 13, the rock shaft being mounted in bearings 11 on the lower side beams of the main frame A and being equipped at one end with a crank arm 15 operatively connected with a pitman 16..

The wires extend down pression of the wires. By arranging the feed spools and tensioning devices C directly above the heddles in the manner set forth, a more direct pull is obtained on the wires than in my prior patent. As shown in Fig. 3, each pair of heddles is slidably mounted in bearings 21 carried by the shed arranged at the front of the machine.

The lay for feeding the fabric and driving the slats into position close to each other consists of a cross head 23, Fig. 3, which has its ends slidably mounted in vertical guides 24 carried by the side beams 2 of the machine, the guides being formed of bars spaced apart to accommodate the extremities of the cross head. This cross head is connected with an oscillatory frame composed of a pair of beams 25 arranged longitudinally between the side beams of the frame and mounted on a horizontal shaft '26 journaled in bearings 27 carried by the upper side beams, as shown in Fig. 1, one beam being disposed behind the other in this figure, so that only one is visible. The rear ends of the beams 25 are connected together by a cross bar 28 shown in Figs. 2 and 3 so as to insure simultaneous movement of the beams. The front ends of the oscillatory beams 25 are provided with yokes 29 which engage rollers 30 mounted on the upper side of the cross head 23 of the lay. The cross head carries depending push bars 31 that are so disposed as to engage the uppermost slat of the fabric when the lay is moved to feeding position so as to properly position the said slat and finally move the fabric one step forwardly.

Arranged on the table B is a horizontallydisposed reciprocatory carrier designated generally by 1) that operates to remove the lowermost slat from the holder for the pile of slats. The holder comprises upright members 33 and 34 mounted on the table B so as to engage the front and rear edges of the slats 19 when arranged in a pile, as shown in Fig. 1. The rear members or standards 34 are spaced above the bottom plate or platform 35 of the pile holder, so that the lowermost slat can be moved rearwardly from under the said standards. The two pairs of standards are spaced from each other so as to engage the slats of the pile adjacent the ends and the slats are adapted to rest horizontally one on another. The function of the carrier D is to remove the lowermost slat and deposit the same on an elevator which changes the slat to be fed to a vertical position and at the same time brings it into cooperative relation with a laterally-movable slat feeder which carries the slat to weaving position. The carrier D is in the form of a rectangular frame composed of front and rear bars 36 and side bars 37, and on these side bars 37 are slatengaging fingers 38 which, as the carrier moves rearwardly, engage the lowermost slat of the pile and carry it out of the pile holder.

The means for feeding the slats to weaving position comprises a follower 39 which reciprocates on a horizontal guide rail 40 disposed behind the slat holder and approximately in the plane of the woven fabric. The follower 39 engages the outer end of the slat fed to it and moves the said slat laterally between the spaced angle bars 24 forming a guide for the lay. The guide rail 40 also constitutes a rest to which the slat is conveyed by means of a swinging elevator arranged between the slat pile holder and rest, the elevator serving to throw the slat from a horizontal to a vertical position. This elevator comprises a pair of swinging arms 41 pivotally mounted on the side bars 37 of the slat carrier D, and on these arms are arranged bars 42 and 43 disposed at right angles to each other to form a shelf which, when in lowered position as shown in Fig. 5, will receive the lowermost slat ejected from the pile holder by the fingers 38, the bar 42 being so arranged as to lie flush with the bottom plate 35 of the pile holder, while the bar 43 forms an abutment against which the slat strikes in its ejecting movement. After the slat is thus placed, as shown in Fig. 5, the elevator is actuated to swing through an angle of ninety degrees to bring the slat into alinement with the laterally-movable slat placer or follower 39. The elevator is operated automatically by the movement of the carrier D. For this purpose, the side bars 37 of the carrier have inwardly extending teeth in the form of spaced pins 44 which are adapted to mesh with teeth 45 on the arms 41 of the slat elevator. These pins are so disposed that when the carrier reaches the end of its movement to the right, Figs. 1, 2 and 4, the carrier will swing clownwardly to slat-receiving position and at the end of the movement in the opposite direction, the elevator will be moved upwardly to slat-placing position. The follower or slat placer 39 is moved in timed relation with the slat carrier and elevator so that the slats are fed successively to weaving position in rapid order.

The lay of the weaving machine and the slat carrier, elevator and feed follower are operated from a single drive shaft by a series of cams, levers or the like, so arranged as to operate the weaving machine and slatfeeding mechanism in timed relation. In Figs. 1, 2, 7 and 8, is disclosed an approved form of operating mechanism in which 46 is the rotary drive shaft which extends transversely to the frame A and is mounted in bearings 47 on the lower side beams 2. On the side of the weaving machine opposite from the slat-feeding mechanism, the shaft 46 is provided with a large sprocket wheel 48, Fig. 1, around which passes a sprocket chain 49 meshing with a small sprocket wheel 50 on a secondary shaft 51, which shaft is provided with a gear wheel 52 meshing with a pinion 53 on the main drive shaft 54 of the machine. Mounted on the shaft 46 are a pair of lay actuators designated generally by E, one of which is shown detached in Fig. 9. Each actuator consists of a lever 55 having rollers 56 at opposite ends which are adapted to successively engage under the rear end of each oscillatory beam 25 of the lay, such rear end being curved upwardly to form cam faces 57 over which the rollers ride in raising the rear ends of the beams and thus depressing the lay. Each arm of the lever 55 is provided with a rail-like shoe 58 arranged at opposite sides of the lever and supported on their respective arms by connecting members 59. The shoes are spaced from the rollers and the outer ends are curved slightly over the latter. These shoes are adapted to engage lateral projections 60 carried by the rear ends of the oscillatory beams 25 for the purpose of drawing the latter downwardly to retract the lay, the said projection being preferably formed by extending the transverse shaft 28 which connects the lay beams or members 25 together. As the actuator E revolves, a roller 56 moves into engagement with the under face of the adjacent beam 25 for producing an upward movement from the position shown in Fig. 8 to that shown in Fig. 7. As the actuator continues to revolve in an anticlockwise direction, the roller 56 will gradually ride from under the member 25, and while so doing, the shoe 58 adjacent said roller will be projected over the projection 60 and cause the member 25 to be lowered as the rotation of the actuator continues, this lowering movement being effected by reason of the more or less parallel relation of the shoe with the radius of the lever 55. In Fig. 8, the heel of the shoe is about to leave the projection 60 so that the member 25 can be moved upwardly by the succeeding roller of the actuator E. It will thus be seen that each roller and companion shoe coiiperates to raise and lower the lay, imparting two strokes to the latter for each revolution of the actuator.

The slat carrier D is reciprocated by a pair of pitmen 61 and 62 which operate, respectively, as pull and push rods for re- 'ciprocating the carrier. The forward ends of the rods are connected by a common pivot 63 with the rear portion of the carrier D, as clearly shown in Fig. 12. The pull rod 61 has its rear end pivotally connected at 64: with a bell crank lever 65 which consists of a pair of arms 66 and 67 connected by a stub shaft 68 that rocks in a bearing 69 on one of the rear uprights of the frame A, as

shown in Figs. 1 and 2. The pull rod 61 is connected with the outer arm 66 of the bell crank lever, while the inner arm 67 is located in the arc of movement of projections 70 on one of the actuators E, which projections are preferably extensions of the axles for the rollers 56. The arm 61 is approximately in a horizontal position'when it is engaged by the projection 70, as shown in Fig. 1, and is moved to an approximately vertical position, as shown in Fig. 7, when the projection leaves the arm, the lever 65 having a swing of about ninety degrees for moving the slat carrier D on its rear stroke to eject a slat from the slat holder to the slat elevator. The forward stroke of the slat carrier is produced by the bell crank lever 71 jection 70 at the opposite end of the rotary element or lever 55 from that projection that has just produced the rear stroke of the slat carrier, as shown in Fig. 7. The upper projection 70 moves through an arc of about thirty degrees, more or less, before it strikes the arm 73 after the lower projection 70 leaves the arm 67 of the lower bell crank lever. As the element 55 continues to rotate after engaging the arm 73, the bell crank lever 71 will be moved in an anti-clockwise direction to thereby move the slat carrier to the right or forwardly through the rod 62. During the time the upper pin 70 moves from the position shown in Fig. 7 to position for engaging the arm 73, the lay of the weaving machine is actuated and the slat feeding mechanism is idle.

As soon as the carriage has reached the limit of its forward stroke, which means that the swinging slat elevator has positioned a slat in front of the laterally-movable follower 39, the lower pin 7 0 has traveled through the are indicated by dotted lines, Fig. 7, and is brought into co-action with the means for operating the follower 39. For this purpose, a third bell crank lever 75 is employed which consists of a downwardly-extending arm 76 arranged to be engaged by the lower pin 70 and an upwardly-extending arm 77 which is connected by a link 78 with a horizontally swinging arm 79 on a vertical rock shaft 80 which, as shown in Fig. l, is mounted in bearings 81 on the side beams of the frame. The arms 76 and 77 are attached to a rock shaft 82 forming a part of the bell crank lever 75 and which is mounted in a bearing 83 on one of the lower side beams of the frame. The vertical rock shaft 80 is provided with a comparatively long forwardly-extending arm 84.- which connects, by means of a link 85, with the slat feeding follower 39, as clearly shown in Figs. 1 and 2, the arm- 84:

and link 85 forming a toggle oint between the follower and rock shaft 80. In Fig. 2, the follower is shown approximately in its mid-position in the act of feeding a slat into weaving position, and when the follower is entirely retracted, the parts are in the dotted line position. In Fig. 7 the lever is in its normal position, and in Figs. 1 and 8, the lever is in the act of turning in an anticlockwise direction so as to swing the arm 79, Fig. 8, as indicated by the arrow, with the result that the follower is moving to place the slat in weaving position. The return movement of the follower 29 is effected through connections between the levers 71 and 75. For this purpose, the lever 71 is provided with a third arm 87 which carries a yoke 88 pivoted at 89 on the said arm and through which slides a rod 90 which has one end pivoted at 91 on a third arm 92 connected with the shaft 82 of the bell crank lever 75. On the rod 90 is an adjustable stop 93 with which the yoke engages to oscillate the lever 75 in a direction to return the slat-feeding follower 39 to initial or slatreceiving position. During the feeding movement of the follower 39, the slat carrier D is idle and the yoke-carrying arm 78 of the lever 71 is in a vertical position, as shown in Fig. 1. It will be observed that the stop 93 is moving toward the yoke 88 as the follower 39 is feeding the slat and the slat will have reached weaving position when the stop, in its upward movement, strikes the yoke. As soon as the projection .70 at the left of Fig. 1, engages the arm 67 to efiect the return movement of the slat carrier D, the arm 87 that carries the yoke 88 will be moved in a clockwise direction so as to act through the stop 93 and rod 90 to tilt the bell crank lever 75 in a direction to move the follower 39 outwardly to its dotted line position, Fig. 2. It will thus be seen that between the levers 71 and 75 is a lost motion connection whereby the first lever operates the second during the return or rear stroke of the carrier D, while the second lever has no effect on the first during the movement of the slat moving follower. By adjusting the stop 93, the movements can be accurately timed so that all the parts work in harmony.

The machine may be driven in any ap proved manner, as for instance, by a belt transmission. On the main shaft 54 is a pulley 9st which passes a belt 95, and this pulley is operatively connected with the main shaft 54: by a clutch designated F and which is shown in Figs. 3 and 12. This clutch comprises a pair of oppositely-disposed shoes 96 carried by one or more cross pieces 97 fastened to a sleeve 98 on the shaft 54. The shoes are fulcrumed at 99 on the said cross pieces and are simultaneously actuated by links 100 pivotally connected to the lug 101 on the sleeve 98. This sleeve has at its inner end an annular groove 102 in which engages the bifurcated end 103 of a shipper or actuating rod 101 slidable in bearings 105 on the frame of the machine. The inner end of the member 104 is pivotally connected at 106 with a link 107 extending approximately parallel with and over the member 104 and is connected with a bell crank lever 108 fulcrumed on the frame at 109. This bell crank lever has one arm connected with a longitudinally-movable rod 110 that extends to the forward part of the machine and is connected with ahandle-operating lever 111 fulcrumed at 112 on the front part of the frame. By manipulating the lever 111, the clutch can be opened or closed for throwing the power on or off the machine.
