nnrrnn sra rns WILLIAM KINGSLEY, OF FAB ROCKAWAY, NEW YORK.

HAMMER.

Application filed May 4, 1917.

To all whom it may concern:

Be it known that I, l/VILLIAM KINosLnY, a citizen of the United States, residing at Far Rockaway, in the county of Queens and State of New York, have invented new and useful Improvements in Hammers, of which the following is a specification.

This invention relates to a hammer vhich may be employed by mechanics in driving securing elements by means of which the sections of a metal ceiling are secured to a support.

The primary object of the invention is to provide a hammer for this purpose in which the head has formed in its striking end a centrally arranged concavity providing the hammer head with a driving surface which may be employed to start and partially drive the securing element into the support to which the ceiling section is to be attached, the completion of the driving operation be ing concluded with an inclined striking surface on the striking end of a hammer head which is arranged concentrically of the concavity and preventing the surface of a ceiling section adjacent the securing element being driven by the hammer from becoming dented or damaged as the head of the securing element is driven up flush with the ceiling section.

l/Vith these and other objects in view the invention resides in the novel combination and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

The preferred embodiment of the invention has been illustrated in the accompanying drawing, although no restriction is neces sarily made to the precise details of construction therein as shown, as changes, alterations and modifications within the scope of the claims may be resorted to if desired.

In the drawing Figure 1 is a perspective view of a hammer, the head of which is constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional view through the hammer head.

Fig. 3 is an end view thereof.

Like characters of reference denote corresponding parts throughout the various views in the drawing.

Referring now to the drawing in detail, the numeral 5 designates a hammer, the head 6 of which is provided at one end with an enlargement 7 having formed in its striking Specification of Letters Patent. Patented Apr. Q, 1918,

Serial No. 166,381.

end a central concavity 8, the wall of which tion is called to the fact that during the driving of the securing element, the hammer is positively prevented from glancing from the head of the securing element when brought into contact therewith, thus preventing the ceiling sections from becoming dented and also enabling the hammer to be advantageously used in corners and similar places.

The striking end of the enlargement 7 is beveled as shown, to provide the head with an inclined striking surface 10, inclining upwardly and rearwardly from the peripheral edge of the concavity to the peripheral edge of the enlargement 7, said peripheral edge of the enlargement being rounded, as indicated by the numeral 11.

Through the provision and arrangement of the inclined striking surface 10, the head f the securing element may be driven fiush against the ceiling sections without denting or damaging the portion of the ceiling section adjacent the securing element and particularly is this true when the securing element is driven into the ceiling adjacent'the inter-section of the ceiling with a wall and especially if the ceiling is provided with an ornamental border or molding.

When the hammer is in use, the nail to be driven thereby is started and driven into the material almost up to the head of the nail by striking the same with the serrated and concave driving face on the striking end of the enlargement 7. The driving of the nail is now completed by striking the head thereof with the inclined portion encircling the driving surface, thus permitting the head of the nail to be driven up flush against the material through which the nail is passed.

From the foregoing description, taken in connection with the accompanying drawing it is at once apparent that a hammer for the purpose set forth has been provided which though comparatively inexpensive to manu facture, is highly eflicient for the purpose set forth.

What is claimed as new is 1. A hammer having a head provided at its striking end with a concave driving surface and an inclined striking surface arranged concentrically With said driving surface.

2. A hammer having a head provided at its striking end with a concavity, the Wall of 7 Which is serrated to provide said head With a driving surface, and a striking surface arranged concentrically of said concavity inclined upwardly and rearwardly from the peripheral edge of said concavity to the peripheral edge of said head.

3. A hammer having an enlargement at one end of its head having a concavity in its striking end, said concavity having a ser rated Wall, an inclined striking face on the said end of the enlargement inclined up- Wardly and rearWardly from the peripheral edge of said concavity to the peripheral edge of said enlargement, said peripheral edge of the enlargement being rounded.

at. A hammer having an enlargement at one end of its head provided with aconcavity in its Striking end a rounded peripheral edge on the striking end of said enlargement, and an inclined striking face on the striking end of the enlargement inclining upwardly and rearwardly from the peripheral edge of said concavity to the rounded peripheral edge on said enlargement.

In testimony whereof I affix my signature.
