Patented June at, Ziftftt Application filed September 24, 1917. Serial No. 193,049.

To ale whom it may concern:

Be it known that I, WILLIAM P. citizen of the United Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in Sash Tools, of which the following is a specification.

The invention relates to a new and useful sash tool and has for its object the removing of putty from window sash.

A further object is to provide a device that CASEY, 21/ States, residing at 1 can be operated by hand or power means.

In the drawings Figure 1 is a perspective view of the tool in operation; Fig. 2 an end view of the frame; Fig. 3 a detail of the cutter and shaft; Fig. 4 a sectional view of a modified cutter and Fig. 5 an end view of the cutter. H

' The tool comprises a frame 1 of rectangu lar form having longitudinal slots 2 formed therein and bearing bosses 3 formed therewith. The bosses 3 are bored axially to a comparatively large hole and eccentric bushings 4 are fitted therein, the bushings have a. bearing hole 5 offset from the center for the purpose of varying the position of the axis of the bearing 5.

A shaft 6 is fitted to journal in the bearing holes 5 and has a shoulder 7 and nut 8 on one end and an actuating crank 9 fitted to the other end. Toothed cutters 10 are fitted on the shaft 6 against the shoulder 7 and secured thereon by means of the'nut 8. The cutters are preferably made in three sections and punched from sheet metal, so the teeth may be divided or broken in their regularity which is found to give better cutting qualities, the teeth being formed as shown in Fig. 5. The shaft 6 is journaled in the bushings 4 When assembled as shown in Fig. 1 so that by revolving the crank 9 the cutters 10 are also revolved.

For gaging the position of the tool when in use a gage 11 is fitted to the under side of the frame 1 and secured against same by means of bolts 12 and thumb nuts 13 so that the position can be set to suit the work.

For the purpose of feeding the tool along a handle 14 is fitted on the frame and held by effect more satisfactory results.

bolts to the slots 2 so it can be varied to give the proper balance of forces. 7

In case it should be desired to actuate the device by turning the crank in the opposite direction, or to the right a pair of gears can. be mounted one on the shaft 6 and another fitted to the crank which can be journaled thereabove.

In some cases where putty is very hard to remove it has been found that the replacing of the standard cutter with a set of cutters of the modified form shown in Fig. i will These are made similar to the cutters 10 except the teeth are beveled on their sides at 15. The flat teeth, however, are used where the material to be removed is not too hard.

In operation, the frame is rested on the window sash and the gage 11 is set so the out ter will cover the path of the putty and the eccentric bushings 4: turned to give the proper depth of cut just so the teeth will clear the glass as shown in Fig. 3.

The crank is now turned While the frame is being pushed along and the cutter engages the putty and removes it in a clean fashion, the tins or points are also removed so that by moving this tool once around the sash the glass can be lifted out.

While the tool is shown in hand form it is obvious that it can be driven by power by attaching a flexible shaft to the shaft 6 in. place of the crank 9 or any other convenient mechanical connection or transmission. The set screws 16 are for locking the eccentric bushings when properly adjusted and as most sash has a standard depth this adjustment is seldom required.

I claim:

1. A sash tool comprising a frame, a guiding attachment adjustably fitted to the frame, a revoluble shaft journaled in the frame and having toothed cutters removabiy attached thereto, and means for laterally adjusting the axis .of the shaft within the frame comprising eccentric bushings fitted between the shaft and frame.

2. A sash tool comprising a frame, a adjustably fitted thereto, a cutter shaft journnaled in-the frame, the said shaft being capable of adjustment with reference to the frame and an adjustable handle fitted to the frame.

3. In a sash tool the combination with a frame having a handle attached thereto, a guiding device adjustably attached thereto, eccentric bushings fitted in the frame, a shaft m t we 1 jonrnaled in the bushings and having a cutter mounted thereon and means for actuat- 10
