HANDLE FOR TooLs.
SPECIFICATION forming part of Letters Patent No. 531,882, dated January 1, 1895.
Q Application filed Tune 9, 1893. Serial lie-477,105- (No modeLl which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.
'My invention relates to a handle for tools, andhas for its object to provide a handle in which the usual jar to the hand is avoided when making a blow and further to increase theeflfect of the blow.
A further object is to oonstruota handle as an article of manufacture capable of being secured to a portion of the handle of tools already constructed.
\Vith these objects in View, my invention consists in the peculiar construction of the several parts and their novel combination and arrangement, all of which will be fully explained hereinafter, and pointed out in the claim.
In the drawings: Figure l is a side elevation of a hammer providedwithmy improved handle. Fig. 2 is a like view showing the hatchet, provided with a handle, in which a coil of fiat metal is employed. Fig. 3 is an elevation of the handle, the tool beingremoved, one ferrule being in section. p
In the use of any tool in which an impact is given by means of a blow upon a handle, there is more or less jar to the hand, and in some classes of work this result is of the greatest, and is frequently attended with injury to the hand. I have overcome these difficulties by interposing a coiled spring betweenthe tool and the handle grasp whereby the jar is practically avoided, and a heavier blow given than would be the result with the same powerexerted upon an inflexible handle.
In ordorto adapt the handle to all classes of tools, the hand grasp and portion to enter the tool are connected with the spring by means of ferrules, whereby the spring and 'posite end being supplied hand grasp may of manufacture, and the handle of a tool of present construction can be cut off, leaving a sufiicient length connected with the tool to enter and be attached to the spring.
be constructed as an article 1 designates the tool, a hammer being shown and a hatchet in Fig. '2.
2 designates the portion of the handle within the tool; 3, the hand grasp, or a portion of handle grasped by the hand and a the intermediate coiled resilient portion of the hendie which may be Eormed of wire, or a fiat bar properly coiled. V
In attaching the handle to a tool the portion 2 is properly secured in the tool, the opwith a ferrule 5, formed with a spiral corrugation internally into which the spring is screwed as shown in Fig; 3, the inner end of the hand grasp,beingprovided with a like ferrule 5, into which the opposite end of the spring screws, the ferrules being secured to the projecting end 5., and the hand held 3 by pins-6. f
It will beseen that my invention is equally well adapted to long handles, as those employed in sledges, stone hammers, &c., the spring being located near the tool with suiiicient rigid projection 2 to cause the face of the tool to strike squarely.
It will be apparent ithat my invention is adaptable to various uses, as, for instance, 1 may form a base ball bat in the same man ner, the lower end representing the tool.
What I claim is- As an article of manufacture, a handle for tools comprising a single rigid section for insertion into the eye of a too], a single rigid hand section, a ferrule upon one end of each section, having a pin passed therethrough to secure the ferrules in place upon the sections, each ferrule having an internal spiral corrugation to receive and secure each end of an intermediate coiled spring section.
In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses.
