Application filed February 6, i922. Serial nassetssa To all whomit may concern: p Be it known that I, RICHARD LESTER WIL- ooX, a citizen of-the United States, residing at VVaterbury' in the countyof New Haven and State of onnecticut, have invented certain new and useful Improvements in- Conipensating Mechanisms, of which'the following is a specification, reference being had therein to the accompanying drawings My invention relates to compensating mechanisms particularly as applied to a heading or upsetting machine, although not limited thereto.

- It is the object of this invention, among other things, to provide a simple'andeffe cient device, so assoc-iatedwi th the means for operating a movablepart, sucha's the punch slide, that variations in the position. of movement thereof may be made without requiring adjustment of itsoperating, means as has heretofore been necessary.

Among other aims and objects of theinvention maybe recited the provision of a device of the character mentioned with a view to compactness and in which the number of parts are few, construction simple, and efiiciency andoperation'hi'gh.

The details and arrangement of parts will be apparent from an inspection of the accompanying drawings inconnection with the description hereinafter contained and wherein a preferred embodimentnof the invention is disclosed for the purpose of imparting an understanding ofthe same.

In the drawings;

Figure 1 is a side elevationfof my iin proved mechanism as applied to'a heading or upsettingmachine, the portions thereof immediately ad acent' tliei'eto also be ng shown therein; p

Figure 2 a front view of the slide, the gate,- a portion of the mechanism whereby thesame is given'a reciprocatory movement upon the. gate and a sectional view of the body of the header; Q

Figure 3 is a fragmentary plan-view of a portion of the compensating mechanism;

Figure 4- is a sectional view thereof, takengenerally upon line4 et of Figure 1';

- F gure 5 is an elevation of the compensating mechanism desi i a feed inechanisnigand Figurefiis a plan view thereof. I Inoaxheacling or'upsetting machine it has dried to be associated with beenthe practice heretofore to operate the punch slide upon the reciprocatory gate from I a rotatingshaft. Itis necessaryfrom time 7 to time to vary the relative position of the slide upon the gate,fthe means heretofore a provided for this purpose requiring first, an

.iadj fist/1116 1117 of parts immediately associated with the slide, usually stop screws and the like, and second, an adjustment of parts bewhich'the slide is actuated. r r

tween the shaft and the rock shaft through lessnsess or ignorance merely adjust the first of said mechanisms and entirely ignore the necessary adjustment of the second; This results in an uncertain and inaccurate movement of the punch slide, excessive wear and strainupon the-parts that is frequently the i the punch-slide is actuated.

only necessary to manipulate the first of said adjustingmeans, the variation in the posi ti-on of the punch "ShdG OCQHSIOHECl thereby being automatically accommodated in the j nechanisni for actuating the punch slide.

, lii the' drawings wherein like characters of reference designate corresponding parts in the 'severalifigures, lO is-a portion ofthe traine of a .llfitttl-ll'lg 'oriipsetting machine, 11 I I the gate that has 'a reciprocatory movement"- thereiiiunder-the;caps'lQ, 13. a rock shaft :journaled in the bearings 14' connected with the frame 1 10.

Forming part of the rock" shaft 13 between the journal bearings 14 are the offset arms 15 joined by the tie ban-16 within which is journaledthe cradle 17; p

1 The punch slide 18, to which is"adjustab ly secured the punch block 19 having the punches 2O fixed therein,- i s movably mounted in the front end of the gate 11."

Slidably inountedi'n the cradle 17 is a shifter plate; 21 held therein, with proper frictional enga ement, by gibs 22 against which abut the adjusting screws 23. A, hinged connection is made between the punch slide 18 and the shifter plate 21 by a pin 24: that passes through the lugs 25 on the shifter plate and the lug 26 on the punch slide.

All of the parts above described are now known in the header art and require no further description herein.

The upper position of the slide in relation to the gate is limited by the nuts 27 threaded on the stud 28 fixed in the gate 11, and passing through the lug 29 on said slide. Ttsdown position is limited by stop screws 30 which are threaded through the 111. 529 and contact with the top of the gate.

This method of adjustment ot the stroke and position of the punch slide is also old and the one always utilized by the operator, to the neglect frequently of the adjustment ofthe slide operating mechanism, necessary to fully accommodate the punch slide inits adjusted limits. I

My invention particularly relates to means for actuating the rock shaitt whereby any adjustment of the position of the punch slide 1S;throu u'h the means above described is automatically compensated and taken.

care 0t, thus eliminating one adjustment.

necessary in the present type of heading or upsetting .n'iachines and the one that is usually forgotten or overlooked by the operator with consequent injury and damage to tie parts and ineffective and uncertain operation.

In the practice of my invention I provide two compensating arms 31 and 32, the former being either made integral with or secured to the rock shaft 18, and the otherrotatably mounted thereon. each being pro-q vided with oppositely disposed lugs 33, these being arranged inpairs one above the other and through both of which pairs project the bolts 34:. Upon each of these bolts is acompression spring 35. held and adjusted thereon to vary the tension thereof by the nuts 36. or the like.

when assembled there is an open space 37 between the adjacent faces of" each of the pairs of lugs 33 so as to permit relative movement. (lonm-wted with the compensah ing arm 2L is a crank arm within which a stud 39 is radially adjustable by a screw lined in relation to the body 10 and is of the usual structure. as well as the cam 45 or crank plate as is usual in headers.

The rotation of the cam 45 actuates the connection. arm as in the direction 01"". its

length and thereby causes the compensating arm 32 tomove about its axis and through the bolts 34 and springs 35 similar movement is imparted to the compensating arm 31 and the rock shaft 18.

As so arranged the adjustment of the parts and especially the springs, is such that they move as a unit until, the punch slide 1.8 has reached the limit of its stroke, either up or down. At this time the compensating arm 31' comes toafull stop and: any additional moven'ient ot the arm: 445

causes the compensating, arm 32 to rock in relation to the compensating arm 31. This is permissible because one of the: springs will be compressed. The first portion of the reverse movement'ott the connection arm a l actuates the compensating arm until the pressure of each of the springs 35. is equal, when the two compensating arms again move as a unit.

fitthe limit of the up stroke the spring at the right oi Figure 1 is compressed and the spring at the left at the limit of the dov" stroke. The extent of compressionot the springs is determined by the amount of over-travel of the connection arm 44, which is designed to accommodate the extreme limits of posit-ion; of the punch slide, or the position of the stud 39 in the crank arm 38.

In Figures 5 and 6 I have shown a construction wherein the feed mechanism may be actuated through the compensatingmechanism. In this form the crank arm 38 is oi slightly dilierent shape and is provided with a plurality of holes 49 therethrough to receive the pin 50 that is projected through one end of a link 51 secured thereon by the screw whereby a pivotal connection is made between said link and the rompensah lug arm. the opposite end oit'said linln by meansol a. pin 53?, being w'muerted with the feed arm 54.

The feed mechanism adjacent to the link 51 is shown in Figure 5 by broken lines, the same being of the usual form and constituting no part of this invention.

This modified form of mechanism operexactly as that shown in the preceding figures with the exception that duringthe movement of the crank arm 38, the feed mechanism is actuated through the link 51. The several holes 4&9 in said arm permit the link 51 to be connected thereto at points varying in distance .t'ron: the axis. of the rock shaft 13, which provides for a variation in the length of the feed.

liiiinor changes and alterations may be made wit iin invention. aside it'rom, those herein suggesteiil, andv T.
