GLAZIERS HAMMER.

SPECIFICATION forming part of Letters Patent No. 752,454, dated February 16, 1904.

Application filed $eptember 11, 1903. Serial ITO-172,741. (N0 model.)

To all whom it may concern.-

Be it known that I, J AGOB S. HovLAND, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Glaziers Hammers; and I i do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to implements for glaziers use.

One object is to produce a hammer which shall be so shaped and proportioned as to be a relatively light implement and at the same time sufliciently heavy to be efiective for its intended use in driving flat brads, pins, or diamonds into the wooden sash of a windowframe 7 Another object of the invention is to pro duce a hammer having such shape that the user may take hold of it in any manner at the handle and find it ready for use on the instant-that is to say, either end of the head may be used as the driving end with either face of the hammer uppermost.

Another object of the invention is to produce a hammer which shall be neat in appearance, durable in use, relatively cheap, and which may also be used to cut or scrape putty or other similar objects.

These and other advantages of my invention will be fully recognized in view of the attached drawings and accompanying description and claims.

In said drawings, Figure 1 illustrates in a perspective view a glaziers hammer constructed in accordance with my invention. Fig. 2 is a side view of the head. View of the head. Fig. 4 is a side view of a modified form of head, and Fig. 5 is an end .view of still another modification of the construction of the head.

Referring now more particularly toFigs. 1,

2, and 3, the letter A designates the hammer as a whole, a beingithe head and b the handle,

of wood or other suitable material. This handle may be of any suitable shape; but I have found that the most convenient handle is one which embraces the grip portion proper, b,

Fig. 3 is an endhaving a shouldered tenon or end 5 (shown in dotted lines in said figures) adapted to engage with a wedgefit a suitable recess in the shank a of the head a. As shown in said Figs. 1, 2, and 3, the head is of symmetrical configuration, its shank atbeing disposed centrally of both median lines, as clearly seen in Figs. 2 and 3. The ends a of the head in this the preferred form are extended equally on either side of the shank a. The shank a is truncated in form, being "largest where it unites with the hammer proper.

The hammer-head a is in the form of an isosceles triangle in cross-section, (see end view, Fig. 3,) its two sides 66 a being equal, and is united to the shank a at the base of the triangle. The end faces a are flat and constitute the hammer-faces proper. The apex of the triangle forms a relatively sharp straight edge a sufficient for many uses to which a putty-knife is employed, although it is not designed for or as a putty-knife. The edge a is parallel with the base of the triangle. The

sides a a are straight and smooth and in a plane at right angles with the plane of the end faces a a. i I

In the modification outlined in Fig. 4: one end a is omitted, the faces a a and the balance of the tool beingprecisely as heretofore described; but the plane of one face a, is coincident with one side or face of the shank a, as clearly illustrated.

In the other modified form, as shown in Fig. 5, the head in cross-section is that of a rightangled triangle, one of the faces, a being in a plane coincident with the side of shank a.

While some of the advantages of my invention may be attained by the use of these and other modifications, I prefer the construction shown in Figs. 1, 2, and 3 and first described as being neat, simple, durable, and exceedingly effective. With this preferred form the glazier need pay no attention to the position of the tool as he picks it up, since when either face a rests upon the sheet of glass either end face a? will be in the desired position for driving the pin or diamond. One of the objects of extending the ends a is to give a desired weight to the implement for use as a hammer, and by having two of such ends, as in the preferred form, the tool is more evenly balanced.

is as follows:

1. A glaziers hammer, the driving-head of which has driving-faces at its endsandout wardly converging flat, side bearing faces which extend the entire length of the head,

said faces being adapted to rest in contact with a flat surface when the handle of the hammer is held at an angle to said surface.

2. A glaziers hammer comprising a handle or grip, and a head provided with a socketed shank to receive the handle end, said head having driving-faces at its ends and outwardlyconverging, flat, side bearing-faces which extend the entire length of the head.

3. A glaziers hammer, comprising a handle proper, and a head,"the latter having a sock eted shank for engagement with the handle end, two equally-beveled bearing-faces, as a a and two equally-extending driving ends, as a a each of the latter being provided with a suitable driving-face, as a, the bearing-faces forming an edge a substantially as shown and described. a

In testimony that I claim the foregoing as my invention I aflix my signature, in presence of two -witnesses, this'15th day of August, 3
