3 Claims.
This invention appertains to improvements in hammers generally, and more particularly to a type thereof especially designed to facilitate the removal and replacement of tire casings of the wheels of all classes of motor vehicles; it having for its primary object to provide a head made of drop forged steel and with a tire casing bead driving end and a bead loosening peen fashioned in a manner to efficiently perform their intended functions and to effectively reduce the chance for the upsetting, i. e., mushrooming, of the metal to a minimum.
Another object of the invention is to provide a hammer head as above characterized with an eye, shaped to receive a handle in a manner to adapt the head for either right or left handed use; a wedge fastening means being employed to assure of a tight and secure fit of the handle when it is engaged with the eye, either from the right or left hand side of the head.
Yet another object of the invention has to do with the provision of a hammer head as hereinbefore specified with a number of angular working surfaces, whereby the impact of blows struck with the driving end from different directions, to loosen a tire casing bead from a Wheel rim and the associated lock or retaining ring, will be taken on plane surfaces, and, also, twisting pressures on the peen, as customarily employed to further loosen and free the bead from the rirh, will likewise be taken on and distributed over like surfaces, thus efiectively avoiding the aforesaid upsetting or mushrooming of the metal; these important results being abetted by the rounding off of all sharp edges, defined by the sides and ends of the head and by the adjacent of said plane surfaces. With the foregoing and other objects and advantages'of equal importance in view, the invention resides in the certain new and useful combination, construction, and arrangement of parts, as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawings, wherein:
Figure 1 is a top plan view of one form of the improved hammer head, in accordance with the invention;
Figure 2 is a side view, partly in section, showing the eye formation having a handle engaged therein to adapt the head for left handed use, the section being taken through the line 22 on Figure 1, looking in the direction of the arrows, and the handle being shown in broken lines;
Figure 3 is a transverse section, taken through the line 3-3 on Figure 2, looking in the direction of the arrows;
Figure 4 is another transverse section, taken through the line 4--4 on Figure 2, looking in the direction of the arrows;
Figure 5 is a fragmentary, longitudinal section, of a modified form of the hammer head; and,
Figure 6 is a plan view of the driving end of the hammer head of Figure 5.
Figure 7 is a sectional view of the handle attached to a head.
Referring to the drawings, the improved hammer head, as it is exemplified therein, is preferably made from drop forged steel, and is generally comprised in a substantially rectangular driving or anvil portion A of a rectangular cross-section and a substantially wedge-shaped end or peen B, merging with the anvil portion the length of these portions being substantially equal. An eye C is formed through the head, in the inner end of the portion A adjacent the merging point of the portion A and the peen B and, preferably, is substantially elliptical in form, with a central straight portion I0 and flared end portions Him and H317, substantially as Shown in Figures 1, 2, l, and 5.
The peen portion B of the head has one of its sides [6a in straight-line continuation with the same side Ma, of the portion A, while its opposite side [6b is formed angularly with respect to the complemental side Nb, of the driving portion A; the free end of the peen being rounded off, as at I60, and of an appreciably less width than that of its connected end which is identical to the width of the driving portion. Also, all edges and corners of the head, preferably, are rounded off, for instance, on a one-eighth inch radius, in order to avoid any nicking or chipping thereof, or the cutting or scarring of the work by the same.
These sides of the head portions A and B are oppositely and equally angled to either side of a plane bisecting the heads A and B longitudi-.
nal-ly thereof and this angled formation is con-. tinued across the ends of the driving and peen:
portions. By this arrangement, the opposite: sides of the anvil and peen portions A and R free of handle openings are provided with oppositely angled plane surfaces IBaand [8b which effectively absorb pressures resulting from twisting motions imparted to the head in the loosening and freeing of a tire casing bead from a wheel rim, while plane surfaces 20a and 281) are likewise provided on the end of the anvil portion A which take the impact of blows struck at oblique angles to the work. Also, by rounding off the free end of the peen B, as indicated at I60, the possibility of damaging a tire casing, as by cutting into the same, is substantially minimized.
7 In the modified form of the hammer head, shown in Figures 5 and 6, the 'end face of the anvil portion A is provided with a centrally disposed fiattened surface 200, which is designed to take the impact of blows struck perpendie this central flattened surface 200, any tendency 3 of a second hammer, employed to strike the tire-iron or other similar tool.
As shown in Figure 7, in fitting a handle to a lhead, its attaching end -is-forcib1y passed through 1 the eye 0 and is then-spread by the driving into the same of a Wedge-W, made of a -'suit- :able wood, which is subsequently spread-by the use of a smaller wedge W, preferably of metal.
In the marketin of hammersyconstructed in :accordance with the invention, they are prefer- :ably sold in pairs, for cooperative use in the removal and replacement of tire casings, one of (each pair being "fitted with a handle H, of one color, for instance, blue, for left handed use, and the other "with a handle H, of a different color, for instance, red, for right handed use, the heads being secured on the handles with the peens B reversed, one with respect to the other.
The heads will be -made in different sizes and weights suitable for their intended uses.
Having thus fully described practical embodiments of my invention, it is believed to'be obvious that I have-provided an 'eificient hammer i a parting from the true scope and spirit of my invention inits broaderasp'ects.
I claim: i 1. A hammer. t'head, comprising an elongated body made from drop forged steel one end portionof the body forming an anvil portionsubstantially rectangular in cross-section,,and the opposite end portion of the body being in "the form of a substantially wedge-shaped peen merging with the anvil end, the two portions 1 being substantially equal in length and the anvil portion bein provided with a handle-receiving .eye opening therethrough adjacent the point -where theanvil portion merges with the peen,

This sur-" .face 200 also permits of a non-skid impact of the hammer head on the striking surface of a 4 sides of both the anvil and peen portions act ing to absorb pressures resulting from twistin' motions of the body in the loosening and freeing of a tire casing from a wheel rim,
