In this illustrative construction, I- have-shown a-machineincluding a base I andhaving an up standing frame 2 on one end thereof and. an upper horizontally disposed extension 3 and the basal: carrying superimposedadjustable die and V ew line L4 punch ,filijngltab'les ira-rid respectively, and the extension -3l-housingQthe operating mechanism for aivertically, movable file carrying slide 6 carry.- ing both an upwardly projecting file Tmovable through theuppjen table 4; and also a dependingpunch file 8. adaptedfto operate on work' on the lower table '5; the upper table 4 and its associated'file and workholder, generally indicated at Air, being adapted to. be swungiout of the way while thelower table 5is injuse, all asliereinafter more fully described;

Referring more. particularly to" the file carrying slide 6, this member is preferablyvery light and formed of aluminum or other light and strong metal, in' order to enable it to op'erateat the desired. high. speed .Without' causing objectionable vibration. It will alsobe obsfervedthat the same is providedthroughout its length'with ani'oppositely bevelled. longitudinally extendin slide portion 9"(Fi'gure 9)1received'ina corre spending ly shapedvertical guideway It) in a stationary narrow guide H suitably fixe'd toan enlargement 3a. on. the free front end'" of the projecting; arm or extension 3'. Here it will also be observedthatthis'member Elias a" lateral extension 12" at'its' top provided withia vertical passagefliti therein adapted to receive the file 'lfand a bottom lateral" extension M" provided with; a "vertical'fpassage lii therein adapted to receive a support, for tli'efile 8"; suitable holding set screws. ea; lit 'bein'gj'pr'ovided" to hold the file or support their desired vertical pnsitic'm'- in these lateralfextensions; Herein; the member 6 between the portion 9 and guideway I6.

is also provided with a shortvertical slot [6 in its upper end between the extension i2 and the adjacent end of the portion 9 and adapted to receive the top 17a of a vertically slotted U- shaped guard i! fixed to guide H and having sides llb which extend down along the portion 9 in suitable grooves therein extending longitudinally thereof, these sides cooperating with the top Na in preventing the entry of fillings Herein also, an upper transverse guard I8 is fixed as at it to the top of the member H and has an aperture 26 in its smaller and rounded front end through which the file 1 projects at a point just beneath the table 4. Thus, it will be observed that the file carrying slide 6 is'guided for movement in opposite directions in the guide l6, while any chips or filings dropping down through the file passage 2i in the upper table 4 are effectually prevented from entering the ,guides by the member H and the guard l8,'both proved crank mechanism for actuating the same. i

This mechanism herein includes a crank pin 22 having its front end extending through an opening 23 in the slide 6 between the bevels thereon and at a point just above the lateral extension i6 carrying the punch file 8. The rear end of this pin 22 is carried by a rod or crank 24 journalled on suitable anti-friction bearings 25 on a cooperating crank pin 2-3 which is, in turn, eccentrically mounted on an eccentric 21 rotatable with a shaft 26 rotatablyadjustable in -a longitudinal passage 29 in a power driven member 30 journalled inanti-friction bearings 3| and 32 at opposite ends of the extension 3. Adjacent faces of the extension 3a and member ll being recessed to provide a substantially round recess 33' and the member H being longitudinally recessed'to provide communicating slots 34 and 35, it will be apparent that when the mem-' ber 36 isrotated, the adjusting shaft 28 will be rotatable bodily therewith and thereby rotate the eccentric 2i andlpin 26 with the crank 24 in such manner as to cause the crink pin 22 to move rapidly up and down in the slot 35 and, accordingly, reciprocate the file carrying slide 6 in the guideway l6. Further, it will be apparent that when the adjusting shaft 28 is adjusted about its axis in the passage 29, the pin 26' carried on the eccentric 21' will be adjusted about the axis of the adjusting shaft 28 in such manner as to increase or decrease, as desired, the distance between the axis of this pin and the axis of the power driven member 36. Thus, with the pin 26 inthe full line position indicated in Figure 7, the maximum stroke of the crank, and consequently of the "file carrying slide 6 and any file thereon, will be obtained, this stroke being equal to twice the distance between the axis of the pin 26 and the axis of the member 36. However, when the eccentric 21 is adjusted about the axis of the adjusting shaft 26 in either direction from the position shown in Figure'l, the axis of the pin 26 is moved to any desired operating position nearer to the axis of the power driven member 36 with a consequent reduction in the length of stroke of the crank 24, slide 6 and any file on the latter. Further, when the axis of the pin 26coincideswith the axis of the member 36, a zero stroke position is reached parted to the slide 6 and any file thereon.

and the eccentric 21, and a correspondingly ta-, 7

pered seat 31 is provided to receive this portion. Further, a coiled spring 38 is provided around the opposite end of the shaft 28 and seated in a coaxial longitudinal recess 39 in the member 36,

while a driven gear 46 is suitably fixed to the extremity of a reduced extension 4| on the end of the shaft 28 and provided with a hub 42 abutting against the end of the shaft 28 and forming an abutment for the adjacent end of the coiled spring 38. Herein also a bracket 43 is provided having a notched or forked end 44 receiving the hub 42 and a likenotched end 45 parallel to the end 44 and a cooperating gear 46 mesh- 1 ing with the gear 46 is journalled in this bracket on a reduced extension 41 on a shaft 48 extending rearwardly in the member 30 in parallel relation to the shaft 28. As shown, the front .end of the reduced extension 4'! is journalled in a suitable recess in the member 30 and a .suitable locking hub 49, corresponding to the-hub 42, .is

fixed to the extension 41 between the end of the shaft and the forked end 45 of the bracket.

Herein, the shaft 48 also extends rearwardly through an endb1ock'56 fixed to the member 36 and protruding from the rear end thereof beyond the bearing 3| and also protruding beyond frame 2 and disposed in parallel relation to the extension 3 beneath the latter and behind table 5.

In a preferred'construction, the hub of this pulley 5! is also tapered, as at 52, to provide a suitable graduation carrying surface, preferably the highest number, 6, is located opposite this zero position, to correspond to the maximum stroke positionof this pin 26. Cooperating with these numbers is also a rotatable dial member 53 suitably keyed, as at 54, to a rearwardly protruding end of the shaft 48 which, as shown at 55 is also threaded and carries a lock nut 56. As a result of this mechanism, it will be apparent that when this nut- 56 is released, the rotatable dial member 53 may be adjustedas desired into any of the positions indicated to varythe location of the pin 26 and, accordingly, to vary the length of stroke of the crank '24 slide 6 and any file thereon as desired; while tightening of the nut 56 will hold'the crank in any adjusted position as the result of friction between'the tapered portion 36 and its tapered seatBl'; [It will also be evident that, depending upon the position of the nut 56, either a friction drive or safety clutch is provided in the ,crank' drive, or the latter when sufficiently tightened is, in effect, positively connected to the pulley 5|.

In the use of the above described mechanism, it will be apparent that eitherthe file 1 or, the

file 8 may be used as desired, depending upon the character of the work, improved means being provided whereby when it is desired to work upon they lower table 5, the upper table: send its associated. mechanism may be readily swung out of the way. Herein, this mechanism, includes a supportingv member 51- which carries the table d and its angle adjusting mechanism, and't-his member 51 is provided; with an L-shaped; rearward extension 58 pivoted at 59 on a. transverse axis on the top-of the extension 3:in rear'of the portion 3a. thereon. Further, it will be observed that the usual roller to engaging and pressing the upper end of the file 15 against; the work isherein carried. on a, rearwardly extending; arm Bl .pivoted ona vertical axis on anupstanding stud 62 on the rear end of the extension 3;

For ordinary die filing, the file l willt be used in a usual mannerwith the parts in theposition shown in Figure 1, the work then being on the table d and the latter adjusted as desired into any suitable compound adjustment obtainable by the adjusting mechanism provided between the table and the frame. Herein,v inv addition to the rollerfiil, carried on a slide 63, longitudinally adjustabletoward and from the file in the free end 65 of the arm 61', a work holding member 65 is provided whicliis similarly adjustable in. this end 64 and so laterally deflected at-its lower end and; adjustable toward. and from the work as to enable this member 65' to hold'downthe work against the table 4' and, accordingly, eliminate the need for the operator to hold the same down with his hand. Attention is also directed-to the universal; adjustment: provided herein for the table d, cooperating arcuate slides 66 andiclamping members ,6! being providedto permit adjustment about a transverse axis and like arcuate slide 68 generally similar to the slides 66 and a clamping bolt 69 being provided to. permit adjustment about a. longitudinal axis which is transverse to the above mentioned transverse axis.

When it is desired to use the table 5 for punch filing as, for example, when filing a flanged-piece suchas illustrated in Figure 1, the arm 6! carrying theroller 60 and work holding member 65 is swung. laterally about" its pivot on the stud 62 to either. position illustrated in Figureb and the table A is then also swung upward about its pivot. 59. into the angular positions illustrated therein. In either position, it. will-be observed that the rear end of the table clears an upward projection!!! on the base of the upstanding stud- 62. and that the table is also adaptedto be heldin inclined position by tightening the screws whichiherein form the pivots 59 for the table support. 58 while the mere weight of the parts holds it in the-vertical position indicated in dotted lines.

In this position of the parts, it will be noted that with the file I. removed, the upper end of the slide 6 is so covered by the stationary guard 58 as effectually to protect the operator against injury by; the moving slide when the operator leans over the work, while the slide 6, guideway ii], and the adjacent portion of the ex ten sion 3 are-of such dimensions and so disposed as not to interfere with the workers viewof the work onthe table 5. Attention here isalso directed to thefile carrying member 1i also provided and having a depending portion; suitably secured in the-vertical aperture in the lateral" extension. Id and the forwardly disposed file carryingportiton l2sin which the fileB-is adjustably mounted, this construction, while not required, being. further. advantageous and facilitating adjustment and making the file and work readily visible. to the operator. Herve. also. it beunderstoodqthat, as shown in Figure 12, the table Ermayhe adjusted.- into different angu lar positions. Asshown, the same; isaadjustable abouta transverse axisby'- adjustment of the set. screws T3 on opposite ends of. a. bracket 14' to. adjust the latter about. a transverse shaft; 15 carriedby the bottom of. the; table 5; whilethe bracket "M; is also provided? with: a. depending shaft lifirjourna-lled on.a veptical axis; in abearing ll carried' by the base- I., this-.shaftlfi being heldinrdifierent angular relationsto this-bearin lit. by. a clamping-screw connection 18;.

While I: have in this application specifically described one embodiment: which by. invention may assume in practice, it will be understood that this form of the same hasbeen chosen for purposes: of illustration and that the invention may be modified and embodied in various. other formswithout departing from its spirit or the scopeof the appended claims.
