SPECIFICATION forming part of Letters Patent No. 512,061, dated January 2, 1894.

Applioationfiled October 28,1892. Serial No. 450,304. (No model.)

To all whom it may concern.-

Be it known that I, FRANK SOHAFER, a citizen of the United States, residing in the city andcounty of Philadelphia, State of Pennsyl- Vania, have invented a. new and useful Improvement in Machines for Coiling or Wind- 1ng Match-Splints, which-improvementis fully set forth in the following specification and accompanying drawings.

lliyinvention relates toimprovements in machines for coiling and winding match splints, and consists of the combination of parts as hereinafter set forth.

Figure 1 represents a partial side elevation and partial vertical section of a machine for winding match splints embodying my inven-- tion. Fig. 2 represents a plan view of the machine. Fig. 3 represents a view of a detached portion, partly sectional. Fig. 4 represents a view of the parts shown in Fig. 3, but in different positions. Fig. 5 represents a vertical section of a detached portion. Fig. 6 represents a View of a detached portion. Fig. 7 represents a perspective view of a detached portion.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings: A designates the frame of the machine upon which is secured the hopper B, the back 0 of which is pivoted to the sides of said hopper as at ato permit said back to swing, in order to'agitate the splints I) placed within said hopper. The back C is connected by a link D, to a crank shaft E, mounted on the frame A,and carrying a gear wheel F, which meshes with a gear wheel G on the driving shaft H.

Within the hopper B is a finger J, see Fig. 2, which is pivoted to the sides of the hopper, and is connected by a linkK with the back 0 of said hopper, said finger when operating, tending to move the splints toward the frontof the hopper.

L designates a grooved wheel or drum mounted on the frame A. The shaft M which carries said drum carries also a gear wheel N, which meshes with the gear wheel N on the shaft H. As will be seen, a .portion of said drum L is within the hopper B.

The drumL is provided with grooves P in its periphery said grooves being parallel to the axis of said drum, and it is further provided with circumferential grooves Q and R, the grooves Q being adapted toreceive endless belts or cords S, which convey the splints b from the hopper B toward the coil of splints A and the grooves R receive the frames T,

which at certain times move the splints b in the hopper B out of the path of the grooves P in the drum L, so'that said drum ceases to be supplied with splints, as shown in Fig. 5. The frame T is pivoted to an elbow lever U, said lever being suitably mounted on the frame A. The belts or cords S pass partly around the drum L, and rollers V and V. Pivoted to the frame A is a frame W, which carries a shaft X- provided with a worm Y, roller Z and gear wheel A. The frame W has also a rising and falling shaft 13' placed at an angle to the shaft X, said shaft B being provided'with a worm wheel 0' which engages the worm Y, see Fig. 3, and a bevel gear wheel D which meshes with a segment E secured to the frame A. The shafts X and B are substantially at right angles to each other, and the shaft- B' is journaled'at one end in a short oscillating shaft or stud L mounted in front of the shaft L, and on the inner side of the frame WV, and'at the other end when lowered, so that the worm wheel 0 is meshed with the worm Y, and has a bearing in an arm or attachment of the frame W. Pivoted to the end 'of the frame W, adjacent to the worm Y, is a pawl F adapted to engage in a recess G in a. lever II, also pivoted to the frame W. The lever H is provided with a link J which is connected to the shaft B, so as to raise and lower said shaft 13' and thereby cause the worm wheel 0' to either mesh "with or be removed from the worm Y, as the case requires.

The gear wheel A, Fig. 2, meshes with a gear wheel K firmly secured to the shaft L mounted on the frame A, said shaft L being the axis of the pivoted frame W.

The shaft H is provided with a fixed pulley M and a loose pulleyP'. The gear wheel N meshes with an idler Q mounted on the frame A, and said idler meshes with a gear wheel R loosely mounted on the shaft L.

Interposed between one side of the gear wheel R and a heads, which is held by nuts S on the shaft L, is a spring T which forces the said wheel R against a collar or shouldered portion R of said shaft, thereby transmitting rotary motion from the said wheel to the said shaft, and consequently to the gear wheel K on the latter.

Mounted on the frame A, and partly entering the hopper B are rubber rollers U which work on the periphery of the drum L, so as to prevent more than one splint leaving at one time the hopper B, by forcing backinto said hopper all splints not in the grooves P, when any one of said grooves reaches a point directly beneath the rollers U. Motion is imparted to said rollers U by a pinion W, on a shaft X, which carries said rollers. The

shaft X by means of the slot Y in an arm' swinging frame A provided with a lever 15 and a tension roller 0 said lever having a recess D adapted to engage a pin or stud E on the frame A, and thus hold the tension roller C normally against the roller V, so that when the belt F which retains the splints when wound in a coil, is passed between said rollers, it will not slip. I The operation is as follows: Within the hopper B are placed the splints b. A roller G around which is wound the belt F is slipped on a pin H on the frame A. The handle B is raised so as to disengage its recess D from the pin E and the swinging frame A and consequently the tension roller 0 thereon is swung away from the roller V, so as to increase the space between said rollers in order to permit the free end J of the belt F to be freely passed between the same.

From this point it is taken to the roller Z, and

the end J inserted in a groove K in said roller Z. See Figs. 6 and 7. The frame A is then moved toward the roller V, andthe recess D in the handle B caused to engage the pin E and thus hold the tension roller firmly against the belt F so that slipping of said belt, after the same has passed the rollers V and O is prevented. The machine is now started, and the back 0 of the hopper B is caused to vibrate, by means of the crank shaft E and link D. This keeps the splints b in constant motion, and thus causes the same to enter the grooves P in the drum L. The finger J assists the back Gin keeping the splints b in motion. The splints in the grooves P re main in the same until they are outside of the hopper B, when they are removed from said grooves by the endless belts or cords S, and conveyed by the same to therroller V. The belt F which is drawn from the roller G receives said splints and winds them around the roller Z in the form of a coil A as shown in Fig. 1. As the coil of splints increases, the shaft X being on the pivoted frame W, is caused to rise or move away from the roller V, and the speed of revolution of said coil decreases, owing to its increasing diameter. The speed of revolution of the gear wheel R is a fixed one, while the speed of the gear wheel K varies, inasmuch as it is governed by the coil of splints, which as heretofore stated revolves faster or slower according to the diameter of said coil. When the coil of splints is nearly finished, the same will rotate much slower than when the coil was started, and consequently the spring T permitsthe gear wheel R to rotate without imparting an equal speed to the gear wheel K, since it isdue'only to=the friction of the spring T that the gear wheel R imparts mo tion to the gear wheel K, and when there exists a difference in the speed of the gear wheels R and K thespring T will slip, and thus permit each of said wheels to rotate at their respective speed without causing injury to the machine. The gear wheel K imparts motion to the gear wheel A and consequently to the shaft X, on which is secured the worm Y, which imparts motion to the shaft B, and consequently to the bevel gear wheel D,which meshes with the segment E. When the coil of splints is being formed, the bevel gear wheel D rotates in the direction indicated by the arrow in Fig. 1, thereby raising'the free end of the swinging frame W in order to move the shaft X away from the roller V, a distance equal to the increased diameterof the coilof splints, said increase occurring at each revolution of said coil. When there remains on the roller G an amount of'belting equal to about three revolutions of the coil of splints the lever .U is operated so as to cause the frame T to raise the splints in the hopper B out of the path of the grooves P in the drum L, as shown in Fig. 5. As the coil of splints continues to rotate, said coil will draw the belting from the roller G but with no splints between This is done to each layer of said belting. insure a firm coil of splints, and to prevent slipping of the belt insaid coil, which would destroy the same. When all the belting on the roller G2 has been taken up by the coil hereinbefore described, the loose end of said belting is secured to the coil in any suitable manner, as for instance, by means of a tack or staple. The coil of splints is then removed from the shaft X and is ready to be dipped so as to supply said splints with heads. When the coil hereinbefore described is removed from the shaft X, said shaft is at a considerable distance from the roller V and as it is necessary that said shaft should be closeto the roller V when a coil of splints is started, the shaft X requires to be lowered, and in order to accomplish this, the pawl F is removed from the recess G and the lever H raised, as shown in Fig. 4. This movement by means of the link J lifts the shaft B and throws the worm wheel 0 out of engagement with the worm Y, and permits said worm and.

worm wheel to rotate at their respective speed. The revolution of the worm Y accomplishes nothing when the free end of the frame W is being lowered, but takes place simply on account of the gear wheel A on the shaft X meshing with the gear wheel K on the shaft L. When the shaft X has been returned to its starting point, the lever H is lowered, and the pawl F engaging the recess G in the lever H firmly retains the latter in its lowered position, thereby causing the worm Y and worm wheel 0' to again engage each other. The lever U is returned to its normal position as shown in Fig. 1, which permits the splints in the hopper B to enter the grooves P in the drum L. Another roll of belting from which a coil of splints is formed, is placed in the machine as hereinbefore described, and the several parts are in readiness to produce another coil of splints. In order to take up the slack in the cords S, when such occurs, the roller V is mounted on a swinging arm M which, owing to the bolt N and nut P thereon, may be lowered thereby carrying with it said roller, and thus tightening or taking up the slack in the cords S, or regulating the tension thereof.

The mechanism for automatically adj usting the height of the shaft which carries the splint coil relative to the diameter of the said coil, and described and illustrated in this application, is not broadly claimed herein, per 86; being described, shown and claimed in an application by me for Letters Patent of even date herewith, bearing Serial No. 450,305.
