WALTER ERNEST BOLSTER, OF BROCKTON, MASSACHUSETTS.
MALLET.
SPECIFICATION forming part of Letters latent No. 698,436, dated April 29, 1902. Application filed December 19, 1901. Serial No. 86,483. (No model.)
To all whom it may ooncerm' Be it known that I, WALTER ERNEST BoL- sTER, a citizen of the United States, residing in the city of Brockton, county of Plymouth, and State of Massachusetts, have invented a new and usefullmprovement in Mallets, of which the following is a specification, reference being had to the accompanying drawlngs.
My invention relatesto mallets, and particularly to mallets for pounding dies for cutting leather and .similar material; and the object of my invention is to provide a mallet in which the parts are so securely interlocked as to prevent their becoming loosened under the repeated shocks to which the succession of blows subject it in use.
One feature of my invention is the yielding means which I employ to secure the l1andle-shank to the mallet. The upper end or end of the handle-shank farthest from the handle is screwthreaded to engage a nut which worksinto a socket in the top disk of the mallet-head. Between the inner surface of the nut and the bottom of the socket is interposed a yielding device, as a spring. By this construction the mallet-head is securely fastened to the handle-shank and will not become loosened even though the nut be so loose on its threads as to be easily turned. Without this device the nut will unscrew and become. loosened under the succession of blows to which the mallet-head is subjected in use, and even a check-nut will not suffice to retain it in place. a
Another feature of my invention lies in the means devised by me to prevent the nut which holds the lower disk on the stem from becoming loosened. These means comprise a nut-lock secured to the handle-shank and provided with a socket,= the walls of which are fitted to engage snugly over the nut. The lower disk is formed with sockets, into which enter lugs that project from the nut-lock. The nut-lockisthus prevented from turning, and so locks the securing-nut inclosed by it.
A third feature of my invention resides in the means adapted to prevent the handleshank from turning. Upon the handle-shank is cast (or may be formed integral therewith) a nut which fits into a square hole in the top of the nut-lock above referred to. This construction locks the handle-shank and prevents it from turning 0d the screw-nut on its upper end.
Other features of my invention and modifications illustrating the same will be hereinafter described.
In the drawings illustrating the principle of my invention and the best mode in which I have contemplated applying that principle, Figure 1 is an elevation showing my new mallet, a part being broken away to show the interlocking construction between the nutlock and the lower disk. Fig. 2 is a central longitudinal sectional view of the mallet shown in Fig. 1.- Fig. 3 is an end view of the nut-lock. Fig. at is a sectional view on line A A of Fig. 2, the handle and nut-lock being removed. Fig. 5 shows in elevation a modified and cheaperconstruction, the top disk being cast upon the stem and not integral with it. Figs. 6, 7, and 8 are details illustrating a modified construction herein-.
after referred to and described. Fig. 9 is a sectional View on line B B of Fig. 2.
The mallet-head is made up of a top disk a, provided with a stem 12 and formed with a central aperture 0 and socket d, a body e, of rawhide or other suitable material, surrounding the stem b, and a lower annular disk f, through which projects the stem 1). The rawhide body 6 is made up of annuli compressed under hydraulic pressure between the end disks (1 and f. The top disk a may be cast integral with the stem b, as shown in Fig. 2, or maybe cast upon the stem or pipe g, as is shown in Fig. 5. The end of the stem 11 is screw-threaded to engage a nut h, which is screwed against the lower disk f.
Through the central aperture 0 passes the handle-shank t, screw-threaded at its upper end to engage the nutj, which works into the socket d and is formed with holes 7c,'adapted to receive the prongs of a spanner. Between the lower face of the nutj and the bottom of the socket cl is interposed a spiral spring Z, which acts as a yielding medium between the nut 7' and the mallet-head and serves to prevent the nut y from becoming loosened under the effect of repeated blows. Near its middle there is cast or otherwise firmly secured upon the handle-shank 'L a nut m, having a polygonal periphery or outline, which fits into an opening 72, polygonal in form, in a nut-lock 0. This nut-lock 0 is prevented from turning by means hereinafter described and serves by its engagement with the nut m to prevent the shank i from turning and becoming loosened from the nutj.
To prevent the nut h from turning and becoming loosened from the stem 17, I provide a nut-lock 0, which fits snugly over the nut h and which is provided with one or more (in the drawings two are shown) lugs p, that engage in sockets q in the annular diskf. The engagement of the lugs 19 in the sockets q locks the nut-lock 0 in place and prevents its turning, and the nut-lock 0 looks the nut h and holds it securely against the tendency to unscrew due to the shock of the succession of impacts. Hence the nut-lock 0 serves a double purpose in that it locks the nut h, as well as the handle-shank 2", from turning.
In Figs. 6, 7, and 8 is shown a modified construction, Fig. 8 being a central longitudinal sectional view, Fig. 7 a sectional view on line C O of Fig. 8, and Fig. 6 a view of the inner face of the annular disk 1". In this modified construction the central body portion of the mallet is made separable from the other parts of the head, and when one of these separable or interchangeable rawhide body portions is worn out it may be replaced readily by another. Thus economy in use is obtained. On the central pipe 8 are threaded the rawhide annuli t, compressed under hydraulic pressure between the metal annuli u. The pipe 3 is upset at both ends, as is best shown in Fig. 7, and is thereby secured to the metal annuli M. In the outer face of each of the metal annuli a is formed a socket a), adapted to receive lugs to, that project from the inner face of each of the end disks :0 and r. The lug-and-socket connection between the up per annulus u and the upper end disk 03 holds the rawhide body portion against turning, and the lug-and-socket connection between the lower annulus u and the lower disk 1" prevents the latter from turning.
In contour my mallet presents no sharp edges, all edges being rounded. This is a valuable feature, for all mallets heretofore made for pounding dies for cutting leather, so far as known to me, have had sharp edges, which are liable to mar the leather-as, for example, the dropping inadvertently or otherwise of a mallet with sharp edges upon a soft skin ruins the skin by reason of the sharp edge cutting into it.
