To all whom itpmay concern:

' Be it known that I, GEORGE W. PERKS, a citizen of' the United States, residing at Springfield, in the county of Clark and State of Ohio, have'invented certain new and useful Improvements in Machines for Filling and Assembling Slide-Boxes, of which the following is a specitain novel features which I will now proceed the actuating-cam therefor. sectional view of a portion of the hopper, showto describe and will then particularly point outin the claims.

In the accompanying drawings, Figure 1 is aplan view of a machine embodying my invention in one form. Fig. 2 is a side elevation of the same. Fig. 3 is a central vertical sectional view taken on the line w'of Fig. 1 and looking in the direction'of the arrows. Fig. 4 is an enlarged detail sectional view of the feeding-hopper and its associated parts. Fig. 5 is a detail perspective view of the agitator detached. Fig. 6 is a similar view of Fig. 7 is a detail ing one of the stripping-arms which cooperate with-the stripping-roller; and Fig. 8 is a similar view of the stripping-roller.

1, the drive being by any suitablemeans as, for instance, a sprocket-chain 9 and sprocketwheels 10 and 11, mounted, respectively, on V the shafts 3 and 7. On the shaft 7 there is loosely mounted a hollow shaft or sleeve 12, which is free to rotate independently of the shaft 7 andwhich is not rotated thereby. This hollow shaft extends through one of the bearings 8, as shown at 13, and its end which projects beyond said bearing has secured on it a ratchet-wheel 14:, by means of which the shaft 12' is given an intermittent rotary movement by suitable mechanism, preferably as follows:

A countershaft 15 is mounted in suitable bearings in the frame 1 and is provided with a sprocket-wheel 16, around which the sprocketchain 9 passes. end thereof adjacent to the ratchet-wheel 14: with a crank-arm 17, to which is pivoted one end of a connecting-rod 18, the other end of which is pivoted to a lug 19 on a disk 20, loosely mounted on the shaft 7 and provided with a flange 21, inclosing the ratchet-wheel 1 1. The flange of the disk 20 is provided with a spring-pawl 22, which engages with the teeth of the ratchet-wheel when the disk 20 moves in one direction and which slips over said teeth without affecting the ratchet-wheel when the disk moves in the opposite direction.

The length of the connecting-rod 18 is preferably made adjustable for the purpose hereinafter set forth, and to that end the said rod is made in two parts, the adjacent ends of which are oppositely-threaded and united by a turnbuckle 23.

On the hollow shaft 12 there are mounted, so as to move in unison therewith and with each other, two drums'or intermittently-rotating carriers 24L and 25. The said drums are separated a suflicient distance to accommodate the filling-hopper between them and'are set in openings in the table 2, so that about half of each drum projects above the table. The peripheral face of each drum is provided with parallel transverse guide ribs or projections 26, forming between. them slideways or receptacles 27, within which the bodies and covers fit, so as to be held and move longitudinally. The slideways of the two drums 24: and 25are equal in number and in direct alinement with This shaft is provided at the,

each other. Preferably one side or edge of each rib 26 is beveled off or rounded, as indicated at 28, so as to enlarge the mouth or opening of the slideways in such a manner as to facilitate the insertion therein of the bodies and covers.

As each slideway reaches its highest position it comes into line with a plunger 29, which is mounted in a bearing 30 on the frame 1, through which bearing its stem 31 is adapted to slide. The outer end of said stem lies in the path of a cam 32, carried on the end of the shaft 7, so that when the rotary carrier or drum is stationary said cam will force the plunger forward. The plunger may be retracted in any suitable manneras, for instance, by means of a spring 33.

The drum 25 has mounted at one side of it a cam 34, secured to the frame 1 and extending upward adjacent to the end of the drum, near the top thereof, diverging forwardly therefrom, as indicated in Fig. 1. This cam serves to engage the ends of the box-covers after they have been inserted in the slideways of said drum as they rise above the table, so that as each cover reaches its uppermost position said cam acts as a stop to hold said cover of the box against outward movement along the slideway and insures its being held in proper position to receive the filled body. Each slideway of the drum 25 is provided at the top and bottom and on both sides of its inner end with springs 35, which are adapted to enter the open mouth of the box-coverand which not only serve to hold said cover in position at this end, but also to facilitate the introduction into the cover of the filled body. These springs are substantially similar to those shown and described in United States Letters Patent, No. 409,481, of August 28, 1889, and therefore need no detailed description here.

36 indicates a slideway supported between the two drums of the carrier on brackets 37 arising from the table 2, said slideway being fixed and in alinement with the two uppermost slideways of the drums when these latter are stationary. Above this slideway 36 and opening into the same is a feeding-hopper 38, in which the matches to be placed in the boxes are kept. One of the inclined walls of this hopper (indicated at 39) is provided with springs 40, secured at their upper ends to the wall of the hopper and extending downward partially across the discharge-mouth thereof, their free lower ends being adapted to rest on the edges of the body which is being filled, restraining the matches from entering the same except successively, beginning with the forward end of the body, and thereby preventing choking of the bodies during the filling operation. In order to prevent clogging of the matches in the hopper, I provide in the space between the two springs 40 an agitator 41, consisting of a plate sliding up and down in said space, being guided and retained therein in any suitable manner-as, for instance, by headed pins or screws 42 passing through slots 43 in the wall 39 of the hopper. This plate has aprojection 44 on its rear face, which passes through a slot 45 in the wall 39 and lies in the path of a rotating cam or striker 46, mounted on a shaft 47, supported in suitable bearings on the wall 39. This cam depresses or moves downward the agitator 41, which is immediately retracted by means of a spring 48. The opposite inclined wall 49 of the hopper terminates some distance above the top of the bodies lying in the slideway 36 and is provided with bearings 50, in which is supported a shaft 51, driven by means of a pulley 52 and belt 53 from any suitable source of power in such a way that the lower portion of said shaft moves in a direction opposite to the travel of the bodies in the slideway 36. It may be here stated that the shaft 47 is driven from the shaft 51 by means of a belt 54 passing around pulleys 55 and 56 on the respective shafts. On the shaft 51 is mounted a stripping-roller comprising a central fluted portion 57 and lateral smooth portions 58, separated from the central portion by spaces 59. This roller is preferably made of rubber, and the central portion is of slightly greater diameter than the lateral portions, its lowermost part being on a level with the top of the bodies, and the flutings therein being of such a size as to receive therein a single match. In the spaces 59 between the sections of the roller are fittedthe stripping-arms 60, preferably made in two parts, as shown in Fig. 7, and so constructed that the central portion 57 of the stripping-roller extends a distance equal to the diameter of a match below the lowermost portion of the strippingarms. The portions of said stripping-arms which extend inward toward the hopper are so curved as to project beyond the face of the stripping-roller above its lower portion, as shown in Fig. 4, thereby preventing the matches in the hopper from coming into contact with said stripping-roller except at its lower portion and removing from the fluted central portion thereof any matches which may tend to stick in the grooves. The stripping-roller has its outer sections 58 made of less diameter than the central sections in order to make room for the heads of the matches, which are of larger diameter than the bodies thereof. The stripping-roller thus constructed will prevent overfilling of the box-bodies, stripping-off and returning to the hopper any excess of matches which may lie upon the top of the full complement in the body.

The guideway 36 serves as a support for a curved spring 61, secured at one end to said guideway and lying adjacent to the edge of the drum 24 immediately in front of the receiving end of the slideway 36. This spring serves to press back into the drum 24 any body which might through carelessness project beyond the drum, and thus come into contact with the slideway 36 when moving up into alinement with it. To the opposite end of the slide 36 and on the rear side .thereofis' secured a curved spring 62, which serves to push the filled bodies fully into the covers in the manner hereinafter set forth.

Opposite the lower portion of the drum 25 is located a plunger 63, actuated by a cam 64:, carried by the shaft 3. The plunger 63 is mounted in a guide 65, carried by a bracket 66, depending from the table 2, and as a means for steadying the plunger I prefer to provide the bracket 66 with asecond guide 67, adapted to receive a guide-rod 68, connected with the plunger 63 by a cross-head 69. Springs 7 0 serve to withdraw the plunger 63 when the cam 64 has passed the same. The location of the plunger is such and its movements are so timed that as each slideway of the drum 25 comes opposite it and the drum comes to rest said plunger moves forward along the, slideway to eject the filled and covered box therefrom.

I have shown the machine as provided with a brake, comprising a foot-lever 71 and lifting-spring 72, said lever being provided with a strap 7 3, which passes around a brake-wheel 74 on the shaft 3, so that by pressure on the foot-lever the operator may instantly stop the machine if necessary.

The machine thus constructed operates in the following manner: The operator is seated at the front of the machine, with the bodies and covers conveniently supported on the table 2. As the carrier composed of. the drums 24 and 25 intermittently rotates the successivelyappearing slideways therein are filled, those of the drum 24 receiving the bodies and those of the drum 25 receiving the covers. When a slideway of the drum 24 comes opposite the fixed slideway 36, the plunger 29 forces the body from the drum 2 L into the slideway 36. Assuming that there are two other bodies in said slideway 36, one filled and the other partially filled, the forward movement of the entering body will push the filled body out of the other end of the slideway 36 into the cover lying in the slideway of the drum 25, which is in alinement with the slideway 36. This cover is held in position by the cam 34, which lies back of it, and by the springs 35, which embrace its receiving end and which serve to'guide the filled body into it. After the filled body has been thus pushed into position it is not en' tirely central within the cover, for the reason that the following body must not so project beyond the slideway 36 as to be engaged by the drum 25 in its next movement. When the carrier moves another step, however, which is after the plunger 29 has returned to its normal position, the spring 62 bears upon the end of the filled body lying within its cover in the drum 25 and pushes the same into its final position. As the carrier continues to Letters Patent, is

revolve the filled and covered boxes remain in position in the drum 25, in which they are held by frictional contact with the walls of the slideways in which they lie and by their enthe ratchet-clutch. by which the carrier is moved as toinsure the proper alinementofthe slideways on the drums with the fixed slide. 'way between them at each period of rest of the carrier. I

It is obvious that various modificationsv in the details of construction maybe made without departing from the principle of my invention, and I therefore do not wish to be un' derstood as limiting myself to the precise de' tails of construction hereinbefore described, and shown in the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by 1.
