2 Claims.

This invention relates to a guide for use with pins, punches and the like used to fasten a plurality of objects together or to remove already inserted fastening pins from their embedded position in an object. The product of the new invention is extremely economical and of high practical value for a multitude of operations.

The new guide has but a minimum of parts, yet will be found useful in connection with a multitude of pins of various sizes and in con neotion with pinning and punching operations involving objects having various sizes and forms. The new device cooperates with guiding fingers yet provides complete safety for such fingers heretofore frequently subjected to bruises when used to guide pins or punches. Portions of the product of the present invention serve to, respectively, securely hold the device on a surface and to ward off any blow which otherwise may strike the fingers of the person conducting the operation.

The device of the present invention comprises two angular walls having cooperating rounded marginal cutouts to permit positioning of a finger, squared top portions to accept hammer blows, and bottom portions, often squared, which conform to the surface of the material where the pins are to be embedded.

For further comprehension of the invention, and of the objects and advantages thereof, refer ence will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part'of this disclosure- Fig. 1 is an elevational view of the device of the present invention.

Fig. 2 is a frontal elevational view showing the device of the preceding figure with a pin in position.

Fig. 3 shows the device of the preceding views during actual operation in perspective.

Fig. 4 is a top view showing the device in operation.

Fig. 5 illustrates an elevational view of another embodiment of the invention.

Fig. 6 is a like view showing the product of Fig. 5 during actual operation.

Fig. 7 is a frontal perspective View of yet another embodiment of the instant invention.

Fig. 8 shows the device of the preceding figure with a pin in position.

In accordance with the invention the guide is formed of two walls In and II in angular position to each other a-n d meeting at edge I2. The

angle between the two walls I 0 and I! may be 90 and will often approximate 90. The two walls I0 and II conveniently have centrally located rounded out out portions I3 and I4 located at the same or approximately the same height. They are further out off to provide a square top portion I5 and a squared or rounded bottom portion IE to conform to the surface of an object to which the guide is applied.

In accordance with the preferred mode of operation of the instant invention, a pin [1 is aligned against the two angular walls In and II and held in position by a thumb l8 holding the pin and pressing into cut out portions I3 and I 4 and cooperating with index finger II! to rigidly hold the device in position. The surface I 6 is thus pressed against e. g. a rounded object 20 at first movably mounted on a V-block 2| and the pin I1 is aligned directly above hole 22 in said rounded object 20. A hammer 23 is used to drive pin I'I into hole 22 with the surface I5 serving to protect the otherwise exposed thumb I8 against any careless hammer blows.

In accordance with the modification shown in Figs. 5-6, one of the angular surfaces I I} ends at its upper end in a rounded index finger guard 24 snugly fitting an index finger IS. The operation of this embodiment of the invention best shown in Fig. 6 where two fiat plates 25 and 26 are attached to each other by means of a :multitude of pins 21. Guard 24 is simply placed around index finger I9 permitting better grasping and readier handling of the guide and insuring added safety to the index finger. The thumb I8 fits into depressions I3 and I 4 and other phases of the use of this embodiment are small)- gous to the ones of the preceding embodiment.

In accordance with yet another embodiment of the invention best illustrated in Figs. 7-8, the two walls I0 and II are perforated at edge portion I2 conveniently by means of centrally located perforation 28 so as to provide added safety and positive guidance in a convenient recess for index finger I9. The device has all the other features of the embodiment of Figs. 1-6 and is accordingly used.

It will thus be seen that novel guide for :many types of pins and punches applicable by obvious modification to tapering pins has been devised. The new structure combines optimum safety with ,great simplicity and usefulness with a large variety of pins and attachable structures greatly varying in size and form.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is: g v

l. A guide for guiding of pins comprising .two walls arranged angularly with relation to each other with adjacent edges secured together and depressions for a thumb and forming cooperating top surfaces warding off misdirected hammer,

blows and also cooperating bottom members conforming to the surface of an object to bepinned, 5

said two walls being centrally perforated along their meeting edge permitting a recess for a finger. I I j v g 2. A guide'for guiding of pins comprising two' walls arranged angularly with relation to each other with adjacent edges secured together and having cooperating centrally located rounded depressions for a thumb, said angular walls having a rounded opening at the junction of their adjacent edges forming a recess for an index finger.
