HAME.

Specification of Letters Patent.

Patented Mar. 31, 131 1.

To all whom it may concern Be it known that I, CHARLEs L. WIED- RICH, of Buffalo, in the county of Erie, in the State of New York, have invented new and useful Improvements in Hames, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention has reference more particularly to sheet metal hames of the type in which the hame is formed from a single piece or blank of sheet metal, and the object of this invention is to produce a neat appearing, strong and desirable hame of improved construction which will resemble a wooden hame in size, weight and general appearance, but will be much stronger and more durable and can be more economically manufactured,

In the accompanying drawings, consisting of two sheets: Figure 1 is a plan view of the metal blank from which the hame embodying the invention is formed. Fig. 2 is a similar view thereof showing the holes for the wear leather and the beads or corrugations for the outer face of the hame. Fig. 3 is a perspective view of the blank bent into U-shape in cross-section. Fig. 4 is an enlarged cross-section thereof in line 4-4l, Fig. 3. Fig. 5 is a perspective view of the wooden core for the hame. Fig. 6 is a plan view of the hame showing the edges of the blank partially bent over the wooden core. Fig. 7 is an enlarged cross-section thereof on line 77, Fig. 6. Fig. 8 is a view similar to Fig. 6 showing the edges of the blank closed upon the core. Fig. 9 is an enlarged cross-section thereof in line 99, Fig. 8. Fig. 10 is an enlarged crosssection in line 10-10, Fig. 8. Fig. 11 is a longitudinal sectional View through the die for bending the hame lengthwise, showing the hame in rear elevation. Fig. 12 is a front elevation of a complete hame. Fig. 13 is a fragmentary longitudinal section through the hame strap attachment. Fig. 14 is a cross-section in line 14-14, Fig. 12.

Like reference characters refer to like parts in the several figures,

In general terms the hame of this invention consists of a hollow sheet metal shell,

or body which contains a solid core of wood or other suitable material extending substantially throughout its length which fills the shell conforming to its shape. The shell is formed from a single piece or blank of sheet metal, which by suitable dies in several successive operations, is shaped to embrace the wooden core and to conform to the usual shape of a wooden hame.

A represents a flat piece or blank of sheet metal from which the hame is formed. This blank is ofthe form shown in Fig. 1 being of somewhat greater width in its central portion and having curved side edges which taper slightly toward their opposite ends, one end of the blank being provided with a lateral ear or extension a. In this blank, while still flat, are stamped holes a a for the tacks or screws which secure the usual wear leather to the hame, and beads or corrugations a a which extend lengthwise of the blank, substantially parallel with its side edges, and converge at their opposite ends to meet in points at a short distance from the opposite ends of the hame. When the blank is formed into a hame, these corrugations serve to add materially to the appearance of the outer or front face of the hame, breaking the smooth contour of this outer face and giving it the appearance of being provided with a central panel portion. These corrugations also serve to somewhat stiffen the outer face of the hame.

The blank --A- is placed between suitable dies and bent into trough or U-shape, as shown in Figs. 3 and 4:. A core B- is then laid in this U-shaped blank. This core, which is preferably of wood, is shaped in cross-section to conform to the cross-sectional shape of the hame when completed, and extends substantially the entire length of the blank. It is provided at intervals throughout its length with kerfs 7) which are cut in the side edges thereof so as to permit the core to be readily bent longitudinally in forming the hame as will be hereinafter explained.

With the core in place, the U-shaped blank is operated upon by suitable dies which bend the side edges of the blank toward each other and partially inclose the core as shown in Figs. 6 and 7; and after this is done, the blank'so formed is further operated upon by other suitable dies which bend the side edges of the blank down and completely close the same over the core, as shown in Figs. 8 and 9. The side edges of the blank will now abut against each other along the inner or rear face of the hame throughout substantially the entire length of the hame, and the ear or extension a of the blank will overlap the opposite side edge of the blank as shown in Fig 10, being bent around the same by the forming dies so as to hold the side edges together at this end of the hame. This overlapping ear also forms an additional thickness of metal to which the'loop for the hame strap can be secured as hereinafter explained. The blank with its core now has the form in cross-section of the completed hame but is straight throughout its length. To bend the blank and its core lengthwise to the shape of a completed hame suitable curved dies C C, Fig. 11, are employed, which en gage the blank adjacent to its opposite ends and bend the same into proper shape. The kerfs b in the side edges of the wooden core permit the core to be readily bent lengthwise by these dies without splitting, breaking or unduly straining the material; The trimmings for the hame may be of any suitable kind and in the hame shown, consist of the ball cap D which fits over the upper end of the hame, the top loop staple E with its loop ring 'e, the line ring F, the draft staple G carrying the usual back strap ring H, and the wear leather I secured to the inner or rear face of the hame opposite to the draft staple. The line ring F- and the draft staple G are secured to the hame by studs -f and -g, respectively, which extend through the body of the hame and are riveted on the opposite side thereof. The top loop staple E' is secured to the hame by screws -e arranged in the opposite ends thereof, which extend through holes in the metal shell of the hame and engage in the wooden core thereof. The wear leather I is secured to the inner or rear face of the hame by suitable tacks or screws z-' which extend through the holes a and engage in the wooden core. Theholes for the studs and other fastening means for the trimmings can be quickly and easily punched in the hame by an ordinary press shear punch as the wooden core forms a backing for the metal so that no dies are required for this purpose. The trimmings can thus be easily attached to the hame.

The attachment employed for the hame strap in the construction shown, comprises a U-shaped attaching member K which straddles the end of the hame and is secured thereto by a bolt or rivet -7v which extends transversely through the hame, passing through the overlapping ear a and the part which it overlaps. This double thickness of metal serves to hold the bolt securely in place and the bolt in turn secures the overlapping edges together and holds them in this position.

While wood is preferred for forming the core of the hame, a core of any other material suitable for the purpose can be used and it is not intended that this invention should be limited to the use of wood alone.

The core serves to stiffen and strengthen the hame and facilitates the formation thereof and enables the hame to be shaped with a greater nicety. It also enables the trimmings to be more quickly and easily secured to the hame and affords a securing means for the tacks and screws which are used for attaching the wear leather and the top loop staple to the hame. By employing a straight core and bending it after it has been placed in the blank, when the blank is bent, the expense of manufacture is materially lessened as the core, being straight, can be easily turned and the same dies operate in a single operation to bend the metal shell and the core.

I claim as my invention:
