SAW-TABLE GAG E.

SPECIFICATION forming part of Letters Patent No. 562,330, dated June 16, 1896.

Application filed October 19, 1895. Serial No. 566,245. (No model.)

To all whom it may concern.-

Be it known that I, FRED HOLMES, a citizen of the United States, residing at City Point, in the county of W'aldo and State of Maine, have invented certain new and useful Improvements in Saw-Table Gages, of which the following is a specification.

This invention relates to the class of woodsawing, and particularly to a saw-table gage, and the novelty will be fully understood from the following description and claim when taken in connection with the annexed draw ings.

The object of the invention is to provide an improved saw-table gage, simple in operation, producing results in measuring the material to be sawed without the loss of time and labor commonly expended in operating this class of gages.

A further object of the invention is to provide improved means for operating the gageblook, to move the latter back and forth in small and great degrees by simply operating a pivoted handle connected to the said block without the operator leaving his post, and to enable him to leave one hand upon the material while the gage is operated.

A still further object of the invention is to provide such connection between the gageblock and its operating-handle that no lost motion is experienced and simultaneously with the least movement of the handle the gage-block is moved.

Other objects and advantages accruing from my improved mechanism will be hereinafter more fully described, and set up in the appended claim.

The invention consists in the novel oonstruction and arrangement of parts and essentiallyin the means for connecting the gageblock with the operating-handle.

In the accompanying drawings, forming part of this application, Figure 1 is a perspective view of a saw and its table with legs removed, showing my improved gage. Fig. 2 is an enlarged longitudinal sect-ion of a modifled form of handle with means for locking the same. Fig. 3 is a perspective view of part of the sliding bolt and its rectangular head or tooth.

The samenumeral references denote the same parts throughout the several figures of the drawings.

The saw-table 1 of common construction is secured upon a frame 2 of ordinary construction. The saw 3 is revoluble through the table upon a shaft 4:, having a pulley 5.

Firmly bolted to the table 1 are two boxes 6, having oil-cups 7, said boxes being adapted to receive and allow to slide through them the gage-block rods 8, one end of which is free and the other end secured to the gage-block 9 in the same plane with the rod-opening in the boxes. This block 9 may be of any desired shape or thickness, with its bottom edge seated upon the surface of the table. Located centrally between the rods 8 in the block 9 is a screw-eye 10, having one end of the connecting-rod 11 pivoted thereto, the other end of the said rod 11 being pivoted to the operating hand-lever 12. This lever 12 has a slot 13 at one end, through which extends into a pillar 14 the pivot-bolt 15, and near its other end is secured a rest 16, which engages the notches 17 of the bar 18. The rest 16 is prevented from rising out of the teeth by the keeper 19, secured to the table 1. By this construction and arrangement the handle is pivoted in the same plane with the rods 8 and screw-eye 10, and the connectingrod also being in the same plane, there is no friction between the parts and no lost mo tion in operating the gage-block, it only being necessary in order to move the gage-block to push the handle inward upon its pivot 15 until the rest 16 disengages the notched bar I 18, the handle then being free to be moved on said pivot, carrying the gage-block to any desired position. Then to lock the handle and hence the gage-block, the handle has only to be pulled until the rest 16 engages one of the notches 17 of the bar 18.

Referring to the modification shown in. Fig. 2, the handle 20 has a pivot-hole 21 at one end, and near its other end a slot 22 with a bolt 23 operated therein. Said bolt is screwed into the head 24: of the spring 25, and the boltcollar 26 keeps the spring bound to the handle with sufficient play to allow the spring to be slid back and forth under the keeper 27. From the collar 26 the bolt is extended and provided with a head 28, having a rectangular projection or tooth 29 at right angles to the bolt to engage the notched bar. This form of locking the handle to the notched bar will be found desirable in large machines Where the strain is greater than in the firstdescribed mechanism.

It Will be observed that either of the handles can be released, operated and again locked by one hand of the operator, leaving the other hand free to guide and arrange the material to be sawed at the same time.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

FRED HOLMES. Vitncsses:
