MALL.

SPECIFICATION formingpart of Letters Patent No. 642,755, dated February 6, 1900.

Application filed March 13, 1899.

T0 at whom it may concern:

Beit known that I, CHESTER PROUTY, acitizen of the United States, residing at Ridgway, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Malls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvementsin malls, especially those adapted for use by stone-cutters, lumbermen, &c., and it is particularly suited for use in driving grabs into saw-logs and lumber, whereby the same may be hauled to skidways, lumber-piles, or any other desired place, and for driving splittingwedges, &c. Its object, among other things, is to provide a tool of even balance, cheap,

simple, and durable in construction, having a metal pounding-surface possessing a slight spring or elasticity whereby the liability of breaking the grabs, wedges, chisels, &c., struck thereby is materially diminished.

A further object is to so construct the device as to permit it to be readily handled, the larger and heavier forms being provided with links whereby they maybe hauled from place to place.

Another object is to provide the face of a block of a mall with a metal band or ring.

Another object is to tighten and bind the parts together.

To these ends the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings,showing the preferred forms of my invention, and in which Figure l is an elevation of one preferred form of mall, and Fig. 2 is a longitudinal central section therethrough. Fig. 3 is an elevation of another preferred form of my improved tool, and Fig. 4 is a longitudinal central section therethrough. Fig. 5 is a View of one form of a blank from which the ring or band of the mall is made. Figs. 6 to 13,inclusive, are transverse sections of different forms of band. Fig. let shows a modified construction, of mall without the link. Fig. 15 shows said mall with its parts detached. Fig. 16 is a Serial No. 708.922. (N0 model.)

View of a small mall of modified construction, showing the body portion thereof broken away.

In constructing these malls I provide a handle A, of suitable wood,tapered upward at its lower end A and having its upper end preferablyprovided with a knob a, the diameter of which will permit it to pass through a tapered bore B in a block B, which is likewise turned from suitable wood. This block B is preferably turned with a concave outer surface b,adapted to receive the convex inner surface of a metal band or ring 0, as shown in Fig. 2, and thereby retain thesame in position. Said band C is formed from a suitable blank, as shown in Fig. 5, which is heavier in its central portion 0 than at the edges. The length of the band C is preferably such that the ends thereof are separated, as shown at O in Fig. 1, when the band is in position, whereby all slack occasioned by the stretching of the band or the contraction of the block B resulting from constant hammering with the tool is immediately taken up. I do not, however, restrict myself to the use of a band having free ends, as the same maybe welded together as shown in Fig. 15, and thus present a smooth surface at all points on the circumference of the tool. Nor do Ilimit myself to the use of a block fitted with a band having an inner convex surface, as in some classes of work it might be desirable to taper the block of the mall from its lower to its upper end, so that it will receive metal of a form similar to that shown in Figs. 6, 7, and 12. v

It is necessary to vary the forms, &c., of the block B and the band thereon to suit different classes of work and to enable the user to strike with the tool from the required positions, Some of these forms of bands I have illustrated in Figs. 3 to 16, inclusive. The bands 0 are always so constructed as to present the most metal at the points which receive the greatest wear, which points vary according to the character of the work.

While it is objectionable to provide the mall with a metallic band of even thickness, in that by such construction the said band quickly wears at the point receiving the most pounding and breaks into parts, yet in some instances, especially where the wear is nearly equally distributed, the band or ring 0 may, if desired, be made and applied as shown in Figs. 14 to 16.

In Fig. 1 I have shown the handle A provided with a link D, pivotally secured to a band cl, which loosely embraces the said handle and is of any desired form. In said figure I have shown a band formed of a single piece of metal bent into proper shape and secured in position by rivets d. In Fig. 3 the ends of the link E are connected to the band 6 by means of chain-links E, said band being formed in two pieces connected by rivets e, as shown. These bands at and 6, being loosely fitted upon the handle A of the mall, normally rest upon the block B, as shown, and are retained upon the said handle by the knob a, as is shown in dotted lines, Figs. 1 and 3.

In assembling the parts of the mall the band C is sprung upon or placed over the block B. The handle A is then passed, knob first, through the eye or bore of the block B, the tapered end A being firmly driven into the bore 13.

In the heavy forms of malls a tapered pick F is driven into the lower end of the handle A, thereby serving to still further bind the parts of the tool together. Said pick F is also of great assistance, especially to lumbermen, as it enables them to readily secure the mall to a log or stump, and thereby prevent it from being lost in the brush or rolling away from an operator who is at work on hilly ground.

It will be readily seen that this mall possesses many advantages. Not only is the metal so distributed as to be thickest and heaviest at the points which receive the greatest wear, but the tool is also well balanced and therefore easy of manipulation. The metal bands by fitting close .to a turned-wood surface have elasticity and spring when' pounded against hard substances, and thereby not only avoid breakage of the driven or pounded object, but prevent undue jarring of the hands of the operator.

Links D orE provide a simple means whereby one or more malls can be conveniently attached to a spreader or chain hook and drawn or hauled from place to place instead of being carried by the men, and as the band of the link loosely embraces the handle it slides downward upon the handle when the tool is in use, and is thus out of the way of the person using the tool.

While I have shown the preferred forms of my invention herein, I do not limit myself thereto, as I am awarethat modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a mall, the combination of a circular tapered block having a tapered bore, a handle adapted to be received by said block, a metal band of uneven thickness compassing said block, and a wedge, pointed at opposite ends and secured within, and projecting from the end of,said handle,substan tially as described.

2. In a mall, the combination of a handle havinga tapered end,a circular, tapered block adapted to receive said tapered end, a metal band having convexo-convex surfaces and compassing, and embedded in, said block and forming the pounding-surface thereof, and a wedge, pointed at opposite ends and secured within, and projecting from the handle, substantially as described.

.3. In a mall, the combination of the handle, the tapered block detachably secured thereto, a metallic band having convexo-convex surfaces and compassing,and forming the pounding-surface of, said block, and a wedge, pointed at opposite ends and secured Within, and projecting from, the end of said handle, substantially as described.

4:. In a mall the combination of the handle, the block detachably secured thereto, and a metallic band embedded in and compassing said block, the ends of the band separated, whereby expansion or contraction thereof is permitted, substantially as described.

5. In a mall the combination of the handle, the block detachably secured thereto, and a metallic band, having convexo-ccnvex surfaces,embedded in and compassing said block, the ends of the band separated, whereby expansion or contraction thereof is permitted, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHESTER PROUTY.
