CHESTER BROGKEIIHURST, OF MAQUON, ILLINOIS.
HANDLE FOR CROSSCUT-SAWS.
Specification of Letters Patent.
Application filed August 23.1907. Serial 110.389.827.
Patented Jan. 21,1908.
T 0 all whom it may concern:
Be it known that I, CHESTER BROOKEL- HURST, citizen of the United States, residing at Maquon, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Handles for Crosscut-Saws, and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
The present invention has for its object to provide a handle, for cross-cut saws that. will possess strength and durability and simple and convenient in operation and firmly hold the saw-blade, enabling the saw to be used with both hands through the medium of a handle and a grip each being independent of the other thereby providing a solid, safe, substantial, ermanent and firm hold for both hands in t e operating of the saw.
The invention consists in a handle for crosscut saws constructed substantially as shown in the drawings and hereinafter described and claimed.
Figure 1 of the drawings is a perspective view of a saw-handle constructed in accordance with my invention, the end of the saw blade being shown in dotted lines. side elevation showing the vertical handle in section also the ends of the horizontal grip, the end of the saw-blade being shown in dotted lines. Fig. 3 a detail view of the sawblade holding bolt.
In the accompanying drawings A represents an upright or vertical handle of wood or other suitable material having a central bore a, a stationary fiat-sided screw-nut b which is let into the handle through a horizontal opening afterwards closed by a plug 0, and a suitable ferrule (1 connected to the lower end of the handle. A saw-blade holdingrod or bolt B extends up into the bore a of the handle A, and a certain length of its end is screw threaded to engage the screw threads of the nut I) and has a slot 6 to receive the end of the saw-blade as indicated in dotted lines. A horizontal bow-shaped grip C which is at a right angle to the handle A enables both hands to be used effectively when sawing, saidgrip having holes at its ends through which passes the saw-blade holding rod, said rod at its lower end having a head f and the ends g of the grip have grooved seats h for the edge of the saw-blade Fig.2 a-
After the saw-blade is inserted through the slot of the bolt or rod subsequent to the same being engaged with the holes in the ends of the grip and the screw threaded end of the bolt or rod engaging the screw threads of the bolt as shown in Fig. 2 of the drawing, by turning the bolt or rod in the proper direction the ends of the grip with the grooved seats will be drawn tightly against the edge of the saw-blade firmly holding it in position and the grooved seats preventing the grip from turning on the rod or bolt.
The employment of the grip in connection with the upright or vertical handle both hands may be brought into use when sawing, and after the saw has cut deep into the log or trunk of a tree the person can release his hand from the handle A and hold the grip C with one hand thereby preventing pinching the fingers between the handle and log or trunk, and also by the use of the grip amuch straighter pull from the back end of the saw is obtained insuring easier sawing and a straighter cut and preventing tipping or wabbling of the saw blade.
The two features of the device which are considered of importance in this class of saw handles, reside in the construction of the spring ends of the grip C and the cup-shaped ferrule. The grip C is constructed of spring metal so as to allow the ends thereof to yield when pressure is brought thereon by the saw and the inner sides of the ends 9 of the grip have the grooved seats h for the edges of the saw-blade so that the blade cannot turn laterally and loosen the slotted screw-rod B. The ferrule d is cup-shaped or formed with a chamber i for the purpose of allowing the spring end of the grip which bears against the ferrule to yield outwardly to enable the sawblade to be inserted between the grooved ends of the grip and enga e the slot in the sore w-bolt B, the space or c amber of theferrule for this outward yielding movement of the end of the grip and by a very slight turn I got the screw-bolt the saw-blade will be firmly tion renders the attachment both simple and eifective, the grip being constructed from a single piece of spring metal and free to act as spring clamps.
Having now fully described my invention, what I claim as new and desire to secure by Letters Patent, is
A handle for cross-cut saws comprising a grip constructed of a single piece of spring metal having its ends free to act as clamps and provided with grooved seats for the edge oi the saw-blade to prevent said blade from turning laterally when clamped thereby, and a handle having acentral bore, a stationary screw-nut, a slotted screw-bolt engaging the nut, and a ferrule upon the end of the handle cup-shaped upon its outer end to form a chamber or space to allow the end of the spring metal grip to yield when the end of the saw blade is being inserted in position, substantially as and for the purpose set forth. In testimony whereof I affix my signature in presence of two witnesses.
