sem Y DEVI on T all whom it may concern: I

Be it known that I, CHARLES-F. BECKER, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in 1 Safety Devices, of which the following is a specification, reference being had to the ac-' companying drawings.

This mvention relates to certain improvements in safety devices and has relatlon more particularly to a device of this general character especially designed and adapted for use in connection with punch presses or the like; and the object of the invention is to provide a device of this general character aving novel and improved means whereby the hand of an operator in engagement with y the work will be thrust to one side before the punching operation, is effected.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention. will be carefully defined inthe appendedclaims.

In-order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, where1n- Figure 1 is an elevational view of a press punch with a'safety appliance constructed in accordance with an embodiment of my invention applied thereto;- Fig; 2 is an elevational view of the safety appliance as illustrated in Fig. l but ina different adj ustment, the coacting portions of the punch being indicated by dotted hues; and F g. 3 is a view somewhat similar to F g. but showing the safety appliance in a still different adjustment. As disclosed in the accompanying drawings, 1 denotes the bolster of a'punch press of any ordinary or preferred construction,

.and 2 the reciprocating slidelor headto which the stamping punch or implement is adapted to be connected. Projecting forwardly of the header slide to one side of the transverse centenand substantially midway X Specification of Letters Eatent. j Patented PM), 23 1915. v Application filed June 6, 191a.

extremity of which is-disposed on alsuitable curve, as indicated at 5, and adjustably'engaged with the free extremity of such rock arm is the striking arm 6, herein disclosed as having its upper end portion provided with a longitudinal slot through which is directedvthe clamping means 7 carried by the rock arm and herein set forth as a conventional bolt and its coacting nut. The

striking arm is adapted to be swung across the bolster 1 in close proximitythereto and I serves to forcethe hand or arm of the operator, holding the work, to one side .upon downward movement of the slide or head 2 sothat the possibility of injury to the hand closed within a rubber sleeve or cover 8, forv reasons which are believed to be self-evident.

As herein disclosed, the requisite rocking movement is imparted to the rock arm 4 through the medium ofthe link 9 pivotally engaged at one extremity to the rock arm 4' intermediate its length and at its opposite extremity to a stud 1O projecting forwardly be readily perceived that upon the reciprocation ofthe slide or head 2 the rock arm 4' will be caused to swing in front .of the slide or head for the purposes desired. As herein disclosed, I have the link' 9 comprised of a from the head 11 ofthe press whereby it will plurality of adjustably connected sections I 12 for purposes which .are believed to be self-evident. I Y

From the foregoing description, it is thought to be obvious that a safety device constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and'is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and itwill also be obvious thatmy invention is susceptible of some change and modificas 'tion without material departure from the principles and spirit thereof and for this reason I do not wishto be understood as its length is the stud 3 to which is pivotally limiting myself to the precise arrangement engaged the rock arm 4, the lower or free and formation of the several parts herein 1 g n in carrying out my invention n prac- 1. The combination'with'a' power operated press having 'ainovable press head, of asafety device I comprising an :arm having its upper extremity vpivotally engaged with the head to one side of the vertical center thereofi the lowerfez'rtremity of f the arm being; ofiset. in a direction, towardthe adgame side of the head, a striking arm adynstably engaged with the-ofiset portion of the arm, an

head.

2. The, combination with a power operetedpress having .amovable press head, of a safety jdevice comprising an arm having itsnpperextremity piyo'tally engaged with the headi t o'one side of the .vertical center thereof," the lower extremity of the arm being ofi'setinaa direction toward the ad; 'jacent sideofthehead, astriking arm overiyi'ng'jthe offset portion-of the arm, said overlying portion of the striking arm being provided with an elongated longitudinally disposed s'lot,'c'lamping means-carried by the ofiset, portion of the arm and disposed means for'positively oscillating said pivoted arm uponeach stroke of thethrough the slot ofthe striking arm to malntam the striking arm in its adjusted position, and means for positively oscillating saidpivoted arm upon each stroke of the I -to which vthe arm is attached, whereby said arm will be oscillated upon each stroke of the head, said link comprising a plurality of relatively adjustable sections.

' In testimony whereof I hereunto al'iix my signature in the presence of two witnesses.
