GUARD.

Application filed January 2, 1924. Serial No. 684,053.

To all whom it may concern .1

. Be it known that I LEROY A. BIGGAR, a citizen of the United States, residing at Oneida, in the county of Madison and State of New York, have invented new anduseful Improvements lowing is a specification.

This invention relates to a guard for a punch press, the general object of the in-' vention being to provide means for preventing th-eoperator from accidentally placing his hand in the press and thusinjuring himself.

, like or corresponding parts throughout the i as opposite tlon. The

Another object of the invention is to so form the device that it can be easily and quickly placed in operative or inoperative position as desired.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

erence will. be had to the accompanying drawings wherein like characters denote several views, and in which Figure 1 is a front view of a press showing the device in use.

igure 2 is a similar in raised position. j

Figure 3 isa side view with the device in lowered position in full lines and in raised position in dotted lines.

Figures 4, 5 and 6 are detail views of the device itsel. i

In these views 1. indicates a long bolt upon which a plurality of fingers 2 are threaded, the fingers being spaced apart by the washers 3. The fingers are arranged in two sets with the fingers of the different sets extending in directions though said fingers can be adjusted to extendin any desired direcends of the bolt pass through the eye members 4, the parts being held assembled on the bolt by its headengaging one eye member and its end 5, engaging the other eye member. Each eye member passes view with the device a through a. loop formed on a link 6 and a rod 7 is supported by a loop at the other end 1 of this link. Each rod 7 passes through a neat-ed with each link 8 by a rod 10 which in Guards, of which the fol-.

\ be easily passes through loops formed on the links. Each link 9 has a looped end engaging the stem of an eye member 11, the eye of which is fastened to the ears of a; bracket 12 by the bolt 13. These brackets are adapted to be bolted to a press such as shown at A and it will be seen that by reason of the various hinge connections the device can be adjusted so that it will fit almost any kind of a press and that it is capable of being swung upwardly so as to expose the opening in the press, as shown by the dotted lines in F igure 3 but can be swung downwardly as shown in Figure 1. The lingers can also be adjusted to various positions. The fingers are made a suitable length to guard the die and also guard the press head.

From the t'oregoing it will be seen that the device can be easily and quickly adjusted to it is to be used and it can moved to any desired position by the operator to permit him to place the obthe press onwhich sets to be worked in the press and to remove y j v p them therefrom and it the operator does not In describlng my invention 1n detail, refwish to use it, it can be swung upwardly out of the way without unloosening any bolts.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I. desire it to be understood. that I may make changes in the construction and the combination and arrangement of the several parts, provided that such changes lall within the scope of the appended claims.

What I claim is i 1. Afguard of the class described comprising a bolt, aplurality of fingers threaded thereon, washers threaded on the bolt for spacing the fingers apart, eye members for supporting the bolt, a pair of brackets and supporting the bolt, a pair. of brackets and a .plurality bf hinged partsfor connecting the brackets with the eye members, said hinged parts comprising a number of looped links and rods engaglng the loops and the eye members having stems for engaging some of the loops. loop formed one l1nk8 and a link 9 1s con- In testimony whereof I aflix mysignature.
