GEOSSCIJ'T-SAVJ HANDLE.

Application filed May 31,,

To all whom it may concern:

Be it known that 1, Bonner G. GAoNoN, a citizen of the United States, and resident of Eagle Lake, in the county of Aroostook and State of Maine, have invented a new and useful Crosscut-Saw Handle, of which the following is a specification.

This invention relates to improvements in saw handles, and particularly to a removable saw handle, adapted for use on cross cut saws.

An object or" the invention resides in providing a saw handle having means for re movably locking the end portion of a saw thereto.

Another object of the invention resides in providing a saw handle structure, wherein a handle portion is formed with a hollow sleeve receiving and housing a spring member attached to the tension adjusting means at one end of the handle portion, while the other end is attached to a split bar member, movably mounted in the other end portion of the handle, and having the slot therein arranged in alignment with the slotted end portion of a saw receiving member, said bar member having a locking lever at the end adapted to engage one edge of a saw, for looking it in the saw receiving member to be held therein by the tension of the spring housed within the handle.

The invention also includes other objects and improvements in the details of construct on and arrangement of the parts, which are more particularly pointed out in the following description and claims, directed to a preferred form of the invention, it being understood. however, that various changes in the specific construction, and arrangement of these parts may be made, without departing in any way from the spirit and scope of the invention as described and claimed.

In the drawing, forming a part of this application Figure 1 is a side elevation of the end portion of the saw equipped with a handle constructed according to this invention.

Figure 2 is a vertical transverse sectiona1 view, through the saw handle, the looking lever being in released position.

Figure 3 is a vertical sectional view, taken at right angles to the section shown in Figure 2, through the saw handle.

The improved handle includes a hollow handle member 1, which is formed with an 1923. Serial N0. 642,702.

enlarged bore 2, opening through one end thereof and communicating with a smaller bore 3, at the outer end of said handle member. The smaller bore 3 receives the cylindrical portion 4: of an adjusting memher 5, adapted to adjust the tension of the spring 6, housed within. the bore 2, through the screw threaded connection with the threaded rod 7, having connection with one end oi the spring 6. It will be seen that the rotation of the adjusting member 5 on the end of the handle will effect an axial movement of the screw threaded rod 7, in order to pull the spring through the bore 2. The opposite end of the handle is provided with a reduced outer diameter for mounting a saw receiving member 8, provided with a slot 9 for receiving one end of the saw 10. The inner end of the slotted portion is provided with a plurality of transverse ridges, as indicated at 11, for engaging the end of the saw, and have a bighting action thereon for effecting the rigid mounting of the handle on the end of the saw against slipping. A slotted bar member 12 has the slot therein arranged in alignment with the slot 9 of the saw receiving member 8, and one end of which is connected with one end of the spring 6, while the other end pivotally mounts the end of a slotted lever 13, provided at 1 1, with a pin connection between the slotted end portion which is movable in an eccentrio relation with the pivot 15 of the lever with the slotted bar member, so that said pin is adapted to engage the opposite end of the saw, from that seating against the toothed portion 11, in order to effect the tensioning of the spring 6. for locking the handle on the saw. The lever 13 is of angular torm as indicated in the drawing, having a handle portion 16, at which point the slotted portion is joined. The angular portion is adapted to fit around the end of the saw 10, in the manner illustrated in Figure 1, so that the pin 14 will pass beyond the line or" pull 01" the spring 6 on the pivot lfn in order that the lever will be held in the position shown in Figure 1. The spring 6 may be tensioned by the setting of an adjusting screw'5 to exert a desired pull on the slotted member 12, in order that the saw 10 will be firmlv'held in said saw receiving member, while the same is in use.

It will be seen that a readily detachable or attachable saw handle has been provided, which will be securely held on the end of a saw, during the normal use of the same, through the tension of the spring 6, and the cooperation of the pin 1% and the knife at the roughened edge 11 of the slot 9, in the saw receiving member.

What is claimed is:

1. A saw handle, comp-rising a hollow handle portion, a saw receiving portion mounted on one end of said handle portion and formed with a slot for receiving a saw, a slotted bar member mounted in the handle portion and saw receiving member also adapted for receiving the end of the saw, a resilient member mounted in the handle portion and connected with the bar memher, and an adjustable connection with said resilient member and the other end of the handle, and a rocking lever carried by the outer free end of said bar member adapted for cooperation with the saw receiving member for looking a saw therein.

' 2. A removable saw handle comprising a handle portion formed with a central bore, a coil spring mounted in said bore, an ad- -a lever pivoted to the slotted end portion of said bar member, having a pin mounted eccentrically with the pivotal connection of the bar member, for engagement with the edge of the saw, said lever being operable in one position to effect the engagement of said eccentric pin with the edge of a saw, for looking it in the saW receiving member through tensioning the coil spring, and adapted to release the handle from said saw, in another position thereof.
