' MATERIAL-DISTRIBUTING DEVICE.

This invention relates to material distributing devices, and more particularly to fluid actuated mechanism for distributing material in strand form on reels.

The object of the invention is to provide a fluid actuated mechanism for distributing material in strand form.

In accordance with the general features of the invention there is provided a strand distributor adapted to be given a reciprocatory motion by a double acting hydraulic motor, the distributor upon reaching the limit of its travel 'in either direction releasing a latched lever which operates a fourwayw valve controlling the flow of a fluid, which may be oil, to the opposite end .of the cylinder, the valve lever upon being released instantly moves, due to energy stored in a coil spring during the travel of the distributor, and becomes locked in its new position. The length of the travel of the distributor is regulated by the position of ad justably mounted latch tripping buttons movable with the distributor and the speed of reciprocation thereof is governed by the speed of the take-11,1) means.

It is believed that the invention will be clearly understood from the following description taken in connection with the ac coin an in drawin s illustratin one em- 1. .8, D D

Fig. 2 is a fragmentary-plan view, paitly in section, showing the mechanism in another position; F,

Fig; 3 is a side view thereof; gig. at is an end view, partly in section, an l Fig. 5 is a diagrammatic view illustrating the invention, particularly the means for supplying oil under pressure to the cylinder. Referring to the drawings illustrat' g one embodiment of the invention, a vei t' disposed standard, which may be supported from the floor, is partially indicated at v (Fig. 3), "upon which is mounted a base plate 11. Supported upon the plate 11 is a double acting hydraulic cylinder .12 retained in position .upon the plate 11 by apair of U-bolts indicated at 13. Mounted within the Cylinder 12 is a piston 16 (Figs. 1, 2 and 5) connected to a piston rod 17, which rod at its one end is connected to a draulio valve casing 23.

ically I cross head 18, the o posite end passing through the other end of the cylinder. The cylinder is provided with ports 19 and 20 at opposite ends, which in the operation of the cylinder 12, act alternately as inlet. and outlet ports for the hydraulic medium. The ports 19 and 20 are connected by pipes 21 and '22,- respectively, to a four-way hy- By means of a valve 24 mounted in the casing 23, the pipes 21 and 22 serve alternately as supply and exli-aust pipes for the motive fluid passing into and out of the valve casing 23 through pipes 25 and 26, respectively.

The hydraulic, fluid, which may be oil, supplied by any suitable means, for instance,

a pump 27 1 indicated diagrammatically in Fig. 5, is connected to an open reservoir indicated at 28 containing a supply of oil. The pipe 25 is connected to the outlet end of the pump 27 While the pipe 26 is arranged to drain into the open reservoir 28. The in-' let end of the pump 27 is connected tothe reservoir by a pipe 29. A throttle valve 30 is includedin tlie fluidsu-pply line 25 for regulating the flow of the fluid to the cylinder 12. A bypass'is indicated M31 in the supply pipe 25 between the valve 24 and the outletend of the pump 27 and is provided with a suitable relief valve 32 for limiting the pressure. The by-pass 31 may also con nect to the exhaust pipe 26 as shown in Fig. 5 for draining jointly therewith into the reservoir.

Secured'to the cross head 18 below the cylinder 12 and parallel thereto, 'as viewed in Figs. 1 and-4, is a distributor rod 35 which is reciprocably mounted in a sleeve 36, the

sleeve in turn being rec'iprocabl mounted in a stationary bracket 37 secure to the base sleeve 36 is a collar 10 which is secured to the rod 35 by a pin 13, the opposite ends of the 'pin projecting into oppositely disposed slots 4 1 formed longitudinally in the sleeve 36, the pin being. flush with the outside surface of the sleeve. Normally in Contact with plate 11. The bore of the sleeve 36 is u the end wall oi the step 39 of the sleeve 36, I

as viewed in Fig. 1, is a second sleeve 45 serving as a spring barrel, which is reciprocably mounted between the sleeve 36 and rod35. The end of the rod 35 opposite the cross head 18 projects from the sleeve 36 and through a plug or bearing 46 screw threaded into the sleeve 36, in which it is slidably mounted, the outside diameter of the bearing 46 being the same as the diameter of the sleeve 36, so that it may move into the bracket 37 in the operation of the mechanism as shown in Fig. 2. Mounted upon the rod between the barrel 45 and the bearing 46 is a coiled compression spring 47. In the normal position of the mechanism, as viewed in Fig. 1, at the beginning of a movement in one direction, the spring 47 is under a minimum amount of com ression. Suitably secured to the sleeve igs. 1 and 4) is a stud 50, which is slidable in a longitudinal slot 51 formed in the sleeve 36, the stud projecting rearwardly therefrom as viewed in Fig. 1. I The valve casing 23 is suitably mounted at the rear of the base plate 11, a portion'of the valve casing being entered within an opening 52 formed in the plate 11 so that the valve stem 53 will be positionedat the top side of the plate 11 (Fig. 4). Mounted upon the valve stem 53 is an operating lever '54, the upper end 55 (Fig. 1 and 2) of which lies in the path of the stud 50, carried by the sleeve 45, and is suitably shaped for a sliding therewith. Fixed to the rod 35 an ad oining the bearing 46 is a block 56, the lower end of which, as viewed in Figs. 1 and 3, liesv in the same plane as the lower end of the cross head 18.

Spanning the space between the cross head 18 and the block 56 is an angle 57 whlch is secured to the ends'of the cross head 18 and block 56' by screws 60. Mounted upon the bottom face of the plate 11, as viewed in Fig. 1 and clearly shown in Fig. 4, are two spring plunger housings 61. Carried within t e housings 61 and arranged to be normally moved outwardly by coiled compression springs 62 are plungers 63 and 64. The heads use of the plungers 63 and 64 project, as clearly shown in Fig. 4, through openings 65 formed in the plate 11 and above the top surface thereof. As viewed in Fig. 1, the plungers 63 .and64 are arranged equi-distant from the axis ofthe'valve 24. The free end 68 of the valve operating lever 54, as viewed in Fig. 1, is provided with a shouldered opening 69 wit in which is slidably mounted a pin 70 (Fig. 4) which normally is positioned directly over one or the other of the plungers 63 and 64. The plungers 63 and 64 are adapted to alternately engage within the shouldered portion of the opening 69. As shown in Figs. 3 and 4, the pin 70 normally projects above the top surface of the lever 54 and'is moved downwardly to a position where it Ilis flush with the top surface thereof by one or the other of a pair of lever releasing or tripping buttons 71 and 72. Thepin'70 in moving downwardly presses one or the other of the plungcrs 63 and 64 out of the contact menace each stem) formed in the angle 57 and adapted to be clamped in position by a nut 78 at different points alon the slot. The purpose of providing an adjustable mounting for the buttons 71 and 72 will be pointed out hereinafter.

Secured to the extreme right-hand end of the distributor rod- 35 is a collar 79 (Fig. 5) mounting a pair of strand guiding fingers 80 disposed at a suitable angle and between which the strand indicated at 81 travels in passing from a supply source (not shown) to a suitably driven take-up spool 82.

It is sometimes the practice in reeling strand to provide means for automatically reducing the speed of rotation of the reel upon which the strand is being coiled as the diameter of the coiled material upon the reel increases, thereby providing a substantially uniform tension upon the material during (not shown), the speed of which pulley is automatically varied as hereinbefore mentioned. Carried upon the shaft 85 is a sprocket wheel 87 connected by a chain 88, sprocket wheel 89, shaft 90, sprocket wheel 91, chain 92, sprocket wheel 93, and a shaft 94 to a suitable crank 01' eccentric means indicated at 95 which is connected to the pit man of the pump 27. The driving ratio between the various sprocket wheels is such that the pump is driven at the desired speed; It will thus be seen that the speed of reciprocation of the piston 16 of the cylinder- 12 and in turn the strand guiding fingers 80, through the mechanism hereinbe'fore described will move back and forth across the space between the flanges of the reel at a shown,.the left-hand end of the cylinder 12.

has consequently been connected with the exhaust pipe 26 and the right-hand end with i the supply pipe 25 through the valve 23.

The motive fluid now passes through the pipe 22 at the right, driving the piston 16 to the left and forcing out the fluid through the pipe 21. Carried along with the piston through the rod 17 and'cross-head 18 is the distributor rod carrying the strand guiding fingers 80. Through the pin 43 and col- 7 lar the sleeve 36also moves and in doing so compresses the spring 47 between the bearing 46 and the barrel as hereinbefore described. The stud 50 mounted in the barrel 45 and projecting through the slot 51 formed in the sleeve-36 finally engages upperlend 55 oftlie lever 54 as-clea'rly shown in Fig. 2. Duringthe movement of the stud 50 as, just described the tripping button 71 moving in unison with the rod 35 has engaged and passed over the pin associated with the plunger 63 and to the left thereof as viewed in Fig. 2. The button 71 in passing over the pin 70 moves the plunger 63 to a position Where the top surface thereof'will lie flush with the topsurface of plate 11 as viewed in Figs. 3 and 4, but due I rod 35 will engagethe pin 70,

to the fact that the spring presied stud 50 is not in engagement with the upper end of the lever 54 at this time, no movement bf the lever occurs. With the stud 50 in engagement with one end of the lever 54 and the plunger 63 still within the shouldered open- 35 will further compress the spring 47,'the barrel remaining stationary dueto the stud 50 carriedvtlierebyengaging the lever 54, thereby storing up energy behind the stud '50 which will act to move the stud to the left as viewed in Fig. 2upon the release of the lower end 68 of the lever 54. As the pisten 16 nears the end of its movement to the left, the tripping button 72 moving with the thereby causing the plunger 63 to be moved flush with the top surface of the plate 11 (Fig. 4) and releasing the lever 54 which will be quickly rotated counter-clockwise as viewed in Figs.

1, 2 and 5. Thelower end of the lever 54,

as viewed in Figs. 1 and 2, is provided withoppositely disposed cam-like portions 97 upon the bottom surfaces thereof, as best shown in Fig. 4, which upon actuation of; the lever in; one direction or the other alternately engage the plungers 64 and 63 and move them downwardly, thereby permitting the shouldered opening 69 in the lever to be f concentrically aligned with one or the other.

of the plungers 63 and 64. In the counterclockwise rotation of the lever just de cribed it will engage the plunger 64 and be locked therebyin its reversed position. The but-w positioned vat the left of the lever will bear the same relation to the plungers 63 and 64 asrthey did at the right of the lever, as shown in Fig. 11. v The position of the valve 24' now being reversed the pipes 21 and 22 now become inlet and extoiis 71 and 72 now the i the ing 69 in the opposite end of the lever. the continuing movementof-the distributor rod haust' pipes, respectively, for the fluid to and from the cylinder 12, the piston 16 will thereby be moved toward the opposite or right end of the cylinder. The sleeve 36 has secured thereto a stud 98 indicated in dotted outline in Figs. 1 and 2, which is so positioned upon the sleeve that it has the same relationship with the left side of the upper end 55; of the lever 54' when the lever has been moved to the position just described as the stud 50 bears to the right, side thereof as illustrated in Fig. 1. c The cylinder 16 in moving to the left moves the sleeve 36 and due to the engagement of the left end of the barrel 45 with the collar 40 the barrel also moves and thereby compresses the spring 47. The stud 98 mounted in the sleeve 36 finally engages the upper end 55 of the lever 54 upon its left side as viewed in Figs. 1 and 2. During this movement and before the stud 98 engages the lever, the button 72 freely passes over the plunger 64 without causing a movement of the lever 54 in the same manner as described in connection with the movement of thepiston 16 to the left as hereinbefore described. .Upon engagement of the stud 98 with the lever, the rod 35 continues to move toward the right and further compresses'the spring 47, the barrel 45 remaining stationary. As the piston nears the end of its movement to the right, the

tripping button 71 will engage thei'pin 70, thereby actuating the plunger 64 in the manner described in connect-ion with the plunger 63, therebyreleasing the lever 54 which will quickly rot-ate clockwise as viewed in Figs. 1, 2 and 5, due to the'energy stored in the spring 47. Upon completion of this reciprocation the mechanism will appear as shown in/Fig. 1, and this action is automatically repeated with each arrival of the guiding fingers 80 at the limit of their travel in either direction, as will be obvious. lit will also be noted that this mechanism can be easily adjusted to vary the length of travel of the guiding fingers 80 within the range of the mechanism by-a'djusting the position of the tripping buttons 71 and 7 2 along the slots 75.
