WOODEN SHOVEL.

SPIEGIFICATION forming part of Letters Patent No. 281,158, dated July 10, 1883. application mea March 15, issa. (No man.;

To @ZZ whoml t may concern:

. Be it known that I, FREDERICK A. S'rncnnn, of Cincinnati, in the county of Hamilton and State of Ohio, have inventedrcertain new and useful Improvements in looden Shovels, of which the following is a specification.

' The invention relates particularly to that class of wooden shovels termed ,maltshovels, and used for the turning of grain in the inalting-chamber or elsewhere, in preparing it for brewing, but is adapted for very general app'lication where wooden shovels are used.

Heretofore these malt and kindred shovels have been made either of asingle piece of Wood, both handle and blade being integral, which involved great waste and loss of mat-e5 rial, since the piece from which theshovel was formed must be selected with reference to procuring both handle and blade practically With-- out flaw, and much or all of the breadth alongside the handle must be sacriced; or else the blade has been made of one piece, of sufficient width and length for the purpose, and of course chosen, as before', with reference to its freedom from flaw or blemish, and the handle of ascparate piece riveted to the blade. In these latter, besides the still present margin ofwaste, the joint between handle and blade is liable to soon become loose, and the metallic fastenings necessarily used rapidly increase the defeet by their constant abrasion as the parts workagainst each other. When the blade is of an integral piece, also, vthe shovel becomes worthless as soon as the :edge or toe is worn thin or uneven, and must be thrown away. To remedy this it has heretofore been proposed to apply a removable toe, which, when worn, can be detached and replaced byv another. In order to attach'this toe, ametallic socket has been riveted to vthelower edge of the blade, extending transversely thereacross and receiving the rear or inner 4part of the toe-piece, which has invariably been of slight depth', in

itsgroove or dovetaihwhich runs from side to "Iside of said blade. Y. joint the full width of the blade, and besides There is thus a metallic the greater cost due to such a construction and the wear incidental to the wooden surfaces v from the abrasive action ofthe material being and its securing-rii-fets; when, too, the union of said socket with the blade once becomes insecure, the shovel is practically beyond repair.

Instead ofthe constructions above explained, I propose to form the wooden blade of the shovel of several pieces, united by (loWel-pins or equivalent means, and bound by metallic straps on the lateral edges, the handle being a prolongation of a central piece bound up with others in the vbody of the blade. This permits small pieces of material, which are readily found without defect or blemish, and which otherwise would be wasted, to be worked up in the shovel; or, in cutting large stock, it enables all defections to be avoided and the perfect parts to be laid out and utilized to the greatest economy and advantage. It also insures an all-wood joint between the handle and blade of the strongest character, making the handle practically integral with the blade, and distributing the strain as if it were actually integral. I also propose to uniteto a handleand blade, either of such construction or formed in one integral piece or otherwise, a removable toe-piece, connected with the edge of the blade by means of dowel-pins, and fun ther secured and fastened by tongued or recessed prolongations of metallic bindingstraps, which embrace the lateral edges of both blade and toe-piece, and by catches or screws passing through said prolongations into the material of the toe-piece.

In the drawings, Figure l is an elevation of a wooden shovel, wherein, for the purpose of illustration, the handle and blade are integral, showing one form of binding-strap and fastening for securing the removable toe-piece; and Fig. 2, a transverse section of the same. Fig. 3 is a like elevation of a shovel, wherein the handle and blade are made in a number 'of pieces, and, by way of further illustration, a different but equivalent form of binding-strap and catch or fastening for retaining the removable toe-piece is shown; and Fig. 4, a transverse section of the same.

Ais the blade, andB the handle, of a wooden shovel. So far as the use of the removable toe is concerned, these may be made together, of a single piece, as in Fig. l, and the toe secured thereto by either form of binding-strap shown ,in the figures and hereinafter described, or

IOO

l i i 2s: iasl their equivalents. For reasons previously y given it will, however, be often desirable to construct handle andblade of multiplex pieces; and in Fig.4 3 I have-indicated the` best mode of doing thisA as yet known to me. In said iigure the blade is ,composedof three piecesa central piece, I), integral with the handle, and two iivanking pieces, a-rights and leftsjoined to the iirst by dowel-pins a through their meeting edges. To more firmly bind them together metallicstraps G are applied to the external lateral edges of the blade, running from the base of the handle proper down toward the working-edge, and secured by nails or screws c, passing into each individual piece. Should a removable toe not be employed, these three pieces, with their binding-straps, may constitute the whole shovel; or a fourth permanent piece, corresponding to the toe D herein shown, and, like it, integral the whole width of the blade, may be applied at the end of the three sections, and united with them. by dowel-pinssuch as the pins d-passing into each section, thus preventing` said sections from spreading apart at their lower ends. The straps C will of course be prolonged to em` brace the toe-piece, and secured thereto by nails or screws. Preferably, however, the toepiece will be removable, whether from this sectional blade or from the integral blade, and to this end it will not be glued or permanently fastened to the dowelpins d, projecting from the bottom edge of the blade, but will be provided with sockets to snugly receive the ends of said pins, else, but less conveniently, the pins will be permanently secured to the toepiece and sockets formed in the blade. It will also have at its lateral edges y either a bulge or rib, d', to take into the quasi-tubular sleeves c', afforded by extensions or prolonga tions of the metallic binding-straps, or an equivalent groove, d2, to receive a tongue or dovetail, cl, from such extensions. Whichever is used, the sleeve or the tongue, it will be advisable to give it sufiicient length to inclose or take into a portion of the blade proper, so that the parts may be well braced at the point of union. As thus constructed, after the toe has been inserted and driven home, it will be secured for the period of its usefulness either by screws c, such as before mentioned, passing through the binding-strap and into its body, or by spring pins or catches c, entering into it through said straps, and composed, for eX- aniple, of a plate-spring riveted at one end to the strap, and a pin borne on the other end of said spring and entering through a snug bore in the strap into a socket in the toepiece. When the toe has become so worn as to no longer be of use, the fastening-screw will be removed or the catches withdrawn, and it will be pulled out and replaced by a new one of identical shape or construction, which will be secured by the screws or catches, as before.

It is evident that instead of the dowel-pins connecting the blade and removable toe-piece:

`a tongue and groove extending'transversely along the edges ofthe two maybevused, the lateral binding-straps remaining the same;

and, also,that when dowel-pins Vare employed the position of the metallic straps may, under some circumstances, be changed to bring them beneath the tongue and toepiece,instead of at the lateral edges. Such modiiications, therefore, although not deemed so invariably desirable as the hereinbefore j-described constructions, are to Y be considered vwithin the principle 'of my invention.
