EYELET-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,988, dated December 24, 1889.

Application filed July 31, 1889. Serial No. 319,254. (No model.)

To all whom it may concern:

Be it known that I, DAVID H. OOLES, acitizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Quilting-Machines, of which the following is a specification.

This invention relates to a quilting-machine in which metallic fasteners are used for the purpose of securing the difierent layers of the quilt together.

The novel mechanism which constitutes my invention is described in the following specication and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a front elevation, looking in the direction of arrow 1., Fig. 2. Fig. 2 is a side elevation looking in the direction of arrow 2, Fig. 1. Fig. 3 is a horizontal section in the plane to ac, Figs. 1 and 2. Fig. 4 is a sectional front view of one of the plungers, one of the spears, and the feed-channel for the fasteners, on a larger scale than the previous figures. Fig. 5 is a similar view of the same parts in a different position. Fig. 6 is a horizontal section in the plane a; m, Fig. 4. Fig. 7 is a vertical section in the plane y 3 Fig. 6. Fig. Sis a vertical section in the planey 3 Fig. 1. Fig. 9 is a transverse section in the plane z z, Fig. 8. Fig. 10 is a horizontal section in the plane :0 x Fig. 8. Fig. 11 is a vertical section in the plane a 2, Fig. 2. Fig. 12 is a face View of a portion of the feed mechanism. 13 is a vertical section in the plane g P, on a larger scale than the previous figures. Fig. 14 is a horizontal section in the plane 22 2 Fig. 2.

Similar letters indicate corresponding parts.

In the drawing, the letter A designates the main frame, which supports the Work-table B. The material or the work to which the fasteners are to be applied passes through bethe other, and arranged in relation to each other in the manner indicated in Fig. 2, and they contain the metallic fasteners which serve to unite the different layers of the work. From the hoppers J J 0 extend discharge-channels jj into the spouts 10 k of distributing-boxes K K", and the dischargechannels j 9' are provided each with two gates at b a b", which are opened and closed alternately, so that when the gates a a are open the gates 12 b are closed, and vice versa. If the gates a a are open, the fasteners which drop down into the channels jj are retained by the gates b b and then the gates a a are closed before the gates b b are opened, so that when the last-named gates are opened only those fasteners drop down which are contained in the spaces between the gates at 12 00 b respectively.

The gates a a of all the hoppers .l J are secured to a slide L, which moves in slots in the end pieces of the frame I, Fig. 1, and which is subjected to the action of the spring 0, and the gates 19 b of all the hoppers .I J 0 are secured to a slide U, which moves in slots in the end pieces of the frame I, and is subjected to the action of a spring 0 Fig. 1. The slides L L are moved against the action of their springs c c by cams d d", which extend in opposite directions from a vertical arbor e, to which motion is imparted from a horizontal shaft M, Figs. 1, 8, and 10, by means of an intermediate arbor f, which is geared together with the shaft M by a worm and worm-wheel and with the shaft 6 by cog-wheels, as seen in 7 which serve to bring the fasteners contained in said boxes, heads up, into curved slots Z, Fig. 9, whence they pass out into the conveyors P P. The distributing-boxes and the brushes are devices well known in the art and require no further description.

IOO

.From one of the transverse bars h, Fig. 1, which connect the slides N N rises a pin 11, which engages a cam -groove 0 in a drum which is mounted 011 the shaft M, so that at the proper intervals all the distributing-boxes K K together with their conveyers P P receive a reciprocating motion in the direction of the axis of theshaft M.

The metallic fasteners used in the machine represented by the drawings are eyelets, and they are fed to the work and inserted therein by the following devices: The lower ends of the conveyers P P are made to extend horizontally close over the presser-plate and the work and these horizontal parts are made sufficiently long to contain a number of'say sixeyelets. (Bestseenin Figs/land 5.) Over these horizontal parts of the conveyers are placed forks Q, each of which has five prongs, (more or less.) The shanks of these prongs extend into sockets formed in the lower ends of bars R R which are guided in brackets 19 19", attached to the transverse bars H H, (Figs. 1, 2, and 8,) and which are suspended from levers S S which have their fulcra on pivots q (1 The free ends of the levers S S are subjected to the action of springs 1" T which retain the same in contact with a cams, mounted on the shaft M, Fig. 8. If this cam occupies the position shown in Fig. 8, the forks Q are depressed, so that each of their prongs engages one of the eyelets in the conveyers P. (See Figs. 4 and 5.) As seen from Fig. 4, the eyelet contained in the extreme end of the conveyer is disengaged from the fork Q, and it is situated directly over a spear T and beneath a plunger U, and before the conveyer is moved by the action of the cam 0, Fig. 1,the spear T is made to rise, so that it passes through the work and through said eyelet. Then the conveyerP is moved into the position shown in Fig. 5 and the plunger U descends so as to force the eyelet through the opening formed in the work by the spear and to clinch it by its co-operation with a shoulder formed on the shank of the spear. As soon as this has been accomplished the plunger U and the spear T recede to the position shown in Fig. 4, the fork Q is raised by its spring 1', and the conveyer P is advanced from the position shown in Fig.5 to the position shown in Fig. 4, when the fork Q descends again, ready for the insertion of the next eyelet.

As shown in Fig. 4:, the shank of the fork Q is retained in the socket of the bar R by a pin passing through a slot q, and a spring has a tendency to force the fork down. If the prongs of the fork strike a faulty eyelet or any other unexpected resistance, the fork can yield, and as it yields the metallic plates r r are brought in cont-act and an electric circuit is closed, so as to sound an alarm. The contact-pieces r are provided with electrical conductors (shown by conventional lines) to connect electrically with an alarm and a battery or other source of electricity.

I do not deem it essential to illustrate an alarm and battery, for they may be of any well-known type. when the supply of eyelets in one of the conveyers gives out. For this purpose a spring 5 is secured to the outer end of the conveyers, and the free end of this spring bears against the flanges of the successive eyelets in the conveyers. When the supply of eyelets gives out, the free end of the springs 3 drops into the side of the conveyers and the contact-pieces s 5 close an electric circuit through the alarm. These contact-pieces s s are also provided with electrical conductors in the same manner and for the same purpose as the contact-pie'ces In order to permit the spears T to pierce the work, presser-plates V are brought to bear upon the work before the spears rise, said plates being provided with openings for the passage of the spears. These presserplates are secured to the opposite sides of a head W, to which a rising-and-falling motion is imparted by cams w w, mounted on shaft A and acting upon levers a a, which connect by rods a a with the head W. (See Figs. 1 and 2.) The plungers U are secured to a head B, which is connected by rods 12 b with levers b b, said levers being actuated by cams 19 12 The spears T are carried by a head 0, which connects by rods 0 c with levers c c, to which motion is imparted by cams c 0 In order to prevent the eyelets from being crush ed in the operation of clinching, the spears are fitted loosely into sockets in the head and they rest upon springs 0 Fig. 2, so that they can yield in case of necessity.

The machine represented in the drawings is provided with two rows of conveyers P P and with a corresponding number of spears T and plungers U, so that for each revolution of the shaft A two rows of metallic fasteners or eyelets are inserted into the work. After this has been accomplished the work must be fed forward to receive the next two rows of fasteners. The feed mechanism which I use for this purpose consists of two cams d 01, mounted on the shaft A, which impart motion to two levers (1 Figs. 1, 2, and 14,) that connect by rods (1 with bell-crank levers f f, on which are pivoted the propelling-pawls F, which engage ratchet-wheels e, firmly connected to the roller E, Fig. 1. Springs f retain the levers d in contact with the cams d. A stop-pawl f which engages a ratchetwheel f prevents the roller E from turning backward. By the action of the cams d d upon the levers d the ratchet-wheels e are turned for one tooth and the feed-roller E is turned so as to bring the work in position for the next two rows of fasteners. Of course this feed motion takes place while the spears are down, the plungers are up, the conveyers are at rest, and the presser-plate V is raised.

In order to be able to continue the operation of securing the metallic fasteners An alarm .is also sounded.

into successive quilts without interruption, I I connect the successive quilts at their ends by loose stitches or in a continuous strip, and when the last rows of fasteners have been introduced and clinched in the first quilt I feed the work forward automatically, so as to bring the first fasteningline of the second quilt in the proper position. The feed mechanism which I use for this purpose consists of a mutilated wheel D which is mounted on a shaft E, Figs. 2, 11, and 12. This shaft is geared together with the driving-shaft A, so that it makes one revolution to, say, six revolutions of the shaft A, and one-twelfth of its circumference is provided with teeth a while the remainder of said circumference is plain. The teeth a engage a cog-wheel a which engages a pinion a", which turns loosely on a stud a On the pinion a is firmly secured a crank a, which connects by a rod g with a lever 9 carrying a pawl G, which engages a ratchet-wheel g mounted on the shaft of the feedroller E. In the example shown in the drawings the pinion a has only six teeth, and consequently it makes two complete revolutions during the time the teeth a (twelve in number) act upon the cogwheel a By these two revolutions of the pinion a the pawl G causes the ratchet-wheel g to advance two steps, and the work is fed forward, so as to bring the new quilt in position to receive the first two rows of fasteners. This feed motion takes place during the time the spears, the plungers, and the presser-plate are out of contact with the work.

011 the cog-wheel c is firmly secured a disk 71 which carries two pins h h These pins are in such a position that they bear upon a rim i secured to the mutilated gear D, Figs. 11, 12, and 13, thereby preventing the cogwheel 9 from turning. At the moment the teeth a of the mutilated gear D engage the cog-Wheel a the pin h strikes a cam-groove 1, so that the cog-wheel a is free to turn, and as this wheel follows the action of the teeth a the pin 7L5 rides down over the edge i Fig. 13. As the teeth a? release the cog-wheel a the pins 71 72 are brought in the proper position to ride upon the rim i by the cam-groove 1' and edge 1. By these means the feed-pawl G is held stationary during eleven-twelfths of the revolution of the shaft E, and it is caused to propel the ratchet-wheel g two steps during one-twelth of the revolution of the shaft E.
