FEED IVIECIEAIVISM.

Application filed May 19, 1924. Serial No. 714,528, 7

This invention relates to new and improved feed mechanism, particularly adapt-j ed for use with a header, upsetting machine, or the like, although it is equally adapted for use with many other types of machines requiring a feed device.

It is the object of this invention, among other things, to provide a feed mechanism of the character mentioned, wherein the whereby the possibility of any spring or yielding of the parts is minimized.

To these, and other ends, our invention consists in the feed mechanism having certain details of construction and combination of parts as will be hereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference eesignate like parts in the several figures;

Figure 1 is: a side elevatlon of our new and improved feed'mechanism, as applied to a header, upsetting machine or the like, a portion of which is shown as associated therewith. V

Figure 2-is an end view thereof, the parts in section being taken generally upon line 2+2 ofFigure 1; I

Figure 3 is an elevation of the carrier member and adjacent. parts, some of the parts being shown in section, taken generally upon line 33 of-Figure' 2;

Figure llisra sectional elevation of the clutch mechanism, the parts in section being taken generally upon line L-A of Figure 2;

Figure 5 isa sectional plan view of a portion of the driving mechanism the parts shown in section, being taken'generally upon line 5-5 of Figure 1; and

Figure 6 is an enlarged detail, fragmen-v tary plan view of the cam piece and some of the adjacent parts, the parts in section being taken generally upon line 66 of Figure 3;

In this type of mechanism it is desirable that the length of the-feed should first be uniform and then capable of variation with the maximum accuracy, the minimum labor,

and without disturbing the motion of the parts, that the make and break mechanism connecting the feed'rolls with the source of power should be capable of motion'inde- I pend ently thereof-for the purpose of hand feeding, adjustment of parts, etc., that the feed rolls should stop instantly and'positive' ly at the termination of the feed stroke, and

except at this time should operate freely and without friction thereon bythe stop-mechan1sm,.to makeacc'urate adjustments of the length of feed during the operation of the machine, and to eliminate as far as possible all spring or resil ency 1n the parts so as to feed roll 14: fixed upon the troll-shaft 16 j ournaled in the roll frame 13, and the lower 7 feed roll 15 fixed onthe shaft 17.

The shafts 16 and 17 are operatively connected by the

gears

18 and 19. Secured in the gear 19, by the'bolts 21, is a clutch ring it I 20, or'the lil :e, encircling anotched disk 22,

in each of the notches of which is a cam block '23, roller 24;, and a spring pin 25 moved in one direction by a spring 26.

Rotatably mounted upon both sides'of the 'disk'22, are. the

rings

27 and 28, connected by a plurality of studs 29 that project laterally through the said notches, there being one stud for each of the rollers 24.

Separably secured to the body 12 is a block 3.0, within'which is vertically movable a roll carrier 31 having a roll 82 mounted therein against plate 92. The center of the roll 32 is below the center of'the shaft 17 so that as said roll is moved upwardly, it impinges against theouter face of the ring 20 and locks the same against movemerit. For the purpose of keeping the clutch r ng 20 clean upon the outside, -there is provided a wiper mechanism, comprising a plate 33 having a felt pad 34 therein that lies i V against the face of the ring and is secured to the block by the screw 85 or the like.

All of the mechanism above described is known in the art and constitutes no part of our present invention.

The shaft 17 is journaled in and supported at its outer end, by a bracket 36, which is securedto the frame 13 by the bolts 37. Upon this shaft are mounted t-wo bushings 38 and 39 which are fixed in opposite ends of a carrier 40, to which the notched disk 22 is secured'by the screws 41, whereby the notched disk and earriermove as a unit.

Projecting radially from the center of the carrier 40 is an arm 42, and within the opening 43 therein is a pitman block 44, through which is threadedthe rod 45 having a worm gear 46 on its lower end and held against endwise movement by a collar 47, held against movement by a pin 48. Botatably mounted in the body 12, is a shaft 49 carrying disk 50 to which is adjustably secured a crank plate 51 by the screws 52 that pass through the radial slots 53 and are threaded into the disk 50.

Mounted for movement within the radial slot 54 in the crank plate 51 is the heao 55 of the stud 56, upon which is mounted a bushing 57, both the bushing and stud being held against movement by the nut 58.-

A pitman 59 is journaled at one end upon 7 the bushing 57 and at the other end connect- .first to provide a feed mechanism of, this character with an adjustment that may be direction of-the arrow in Figure 4. VVhenin this position the rollers24 cannot form a- 'to the arm 67, is

ed with the pitman block 44 by the pin 60, and whereby an oscillating movement is imparted to the carrier 40.

The stud 56 is moved toward and away I from the center of the crank plate 51 by the screw 61 threaded in the head'55, and by reason of the graduations 62 upon the face of the crank plate an exact definite length of movement of the carrier 40 is predetermined. If a finer. adjustment of such length is clesired, it is obtained, by moving the block 44 toward and away from the center of the shaft 17. This is accomplished by rotation of the rod 45, through the shaft 63 with a hand wheel 65 thereon. that is rotatably mounted in the carrier 40 and having a worm 64 that meshes into the worm gear 46. By rotation of this hand wheel 65, whether the carrier 40 is in motion or at rest, the relative position of the adjusting block 44 is varied, and through it the length of the feed movement.

be far as at present advised, we are the operated while the same isin motion.

The ring 28 is connected with the carrier 40 through a rockshaft 66 journaled there in, having. a slotted arm 67"at the inner end, thereof, within which is movable a block 68 mounted upon a stud 69.'fiXed in said ring.

011 the end of the rock shaft 66, opposite a cam lever 70, having a cam stud 71 fixed therein. This cam lever.

and through it'the rock arm 66, is rocked in groove 75 therein, into whichproject the guide blocks 76 that are connected Within the control lever 77 by screws 7 8, or the like.

Secured in the collar 74 is the shank 7 9 of a cam piece 80 that slides within a recess 90 in the carrier 40 and havinga cam8l ther on, movable in the path of the cam stud 71 (Fig. 6). r I

The control lever 77 is fixed on a shaft 82 journaled in the bracket 36; Also fixedto the same shaft is a lever 83 which hasa forked outer end that straddles the plunger 84 movably mounted in the block 30 having a head 85 thereon held normally in contact with the underside of the rollcarrier 31 by a spring 86. plunger 84 is a washer 87 and a jamb nuts 88.

Upon movement of the disk 22 in the direction of the arrow in Figure 4, the spring plurality of pins 25 force the rollers 24 onto-the high part of the cam blocks 23 where they engage both the inner face'of the ring 20 and the cam block 23, thus looking all of theparts together and the same thereafter move. as a unit imparting a rotary movement to the rolls 14 and 15 and through this action a.

nism by hand, or for other reasons, the studs 29 are moved into a position so that the rollers 24-cannot engagetheinner face of" the clutch ring 20 and cam blocks 23 at'one On the lower end of this and the same time. This is accomplished by,

changing the relative position of the

roll rings

27 and 28 abouttheir axis through the shifting of the control lever 77 from its full line position in Figure, 2to its broken line position as shown in Figure 2. By this movement the position of the cam piece 80 is shifted and by its engagement with the cam stud 71 lmparts movement to the rock shaft 66 and through the slotted arm 67 and block 68 the studs 29 are advanced slightly in the connection between the clutch ring and cam blocks. a g I The movement of the control lever 77,

" from its broken line to full line position in Figure 2, also actuates the lever 83. which pulls the plunger 84 downwardly against the tension of the spring 86 permitting the roll carrier 31 and roll 32 connected therewith, to move to a position a sufficient distance below the center of the clutch ring 20 to hold the same out'of any engagement therewith. Thus a single movement of the control lever releases both the inside and outside clutch mechanisms, enabling the feed rolls 14: and 15, and the shaft connected therewith, to be rotated at will in either direction.

For convenience in this manual rotation the hub of the gear 18 is provided with a plurality of holes 91, into which a bar or the like may be, inserted.

There arev minor changes and alterations that may be made within our invention, aside from those herein suggested, and we would therefore have it understood that we do not limit ourselves to the exact construe-V tion herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.
