SPECIFICATION forming part of Letters Patent No. 3221165, dated July 14, 1885.

' Application filed March 13, 1885. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM H. DESSUREAU, of Otsego Lake,0tsego county,l\lichigan, have invented a new and Improved Combination- Tool,,of which the following is a full, clear, and exact description.

, My invention relates to a combination-tool designedmore especially for fitting crosscutsaws; and the invention consists of a tool constructed as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my new and improved combination-tool. Fig. 2 is a side view of the opposite side of the tool. Fig. 3 isa plan view, of the tool, and Figs. 4 and 5 are transverse sectional elevations taken respectively upon thelines x x and y y of Fig. 1.

A represents the main body of the tool. This is formed at one end with the screwdriver B, and at the other with the hammer O and slot D, which latter serves as a saw-set to bend the teeth of a crosscut-saw. At one edge the body A is formed with thin projections E, the points a a a of which are on the same plane, while the point b is set back from the line of the points a, and is provided with the set-screws b, to serve as a gage to measure the set of the saw-teeth. Upon one side the body A has the graduation-marks c in inches and parts of inches madeupon it, and upon the other side at the upper edge of the tool the body A is formed with the thin flanges d, which serve to support the tool upon the points of the cutting-teeth of the saw while the plate F is being used to gage the raker-teeth of the saw. The plate F is fitted in a recess, f, formed at the upper edge of the body A, and it is held in place by the set-screw f, that passes through a slot, f in the vertical plate portion f 3 of the plate F, and enters a screw-threaded opening, f ,made in the body A. By means of the set-screw f and slot f the plateF may be raised or lowered as circumstances require, to suit the desired length of the raker-teeth of the saw. The

' horizontal portion f of the plate F is formed with theloop f to receive and hold a flat file saw to uniform length, and the lower portion, f of the loop f is provided with aset-screw, g, for holding the file in place in the loop. The body A is cut back slightly, as shown at h, in linewith the loop f, to form a clearance or space for one edge of the file,and the points a of the body A are ribbed, as shown at t, and just below the set-screw f is formed the rib i, the outer edge of which is on the same plane with the ribs 1'', so that when a file is placed in the loop f and held by setscrew g the ribs 1' t" may be placed against the flat side of the saw and the file brought squarely upon the points of the cutting-teeth of the saw, (the teeth entering the space j )and the tool and file moved evenly along the points of the cutting-teeth tofile them all to the same length. A slot,k, is formed in the horizontal portion of the plate F,in line above the space j, so that the rakerteeth of the saw may be caused to project up through this slot, sothat a file may be passed over them above the plate F to file them down to the proper gage, the upper surface of the plate F serving as a guide or gage for this purpose. Upon the side of the tool that has the graduations c are formed the two horiz'ontal marks, Z, which serve as guides for setfor filing the points of the cutting-teeth of a ting the plate F, the lower mark being the gage for soft wood, the upper one for hard wood. The cutting-teeth of the saw being filed down to the proper length in order to fit the raker-teeth, the plate F will be adjusted to the proper position according to marks Z, and securedby the set-screw f. Then the tool will be placed upon the saw so that the flanges (I will rest upon the points of the cutting-teeth, so that one or more of the rakerteeth will reach up through the slot is, and then a file will be applied to the points of the raker-teeth until they are filed down to alevel with the uppersurface of the plate F. All of the raker-teeth being treated in this manner, they will all have the proper relative length to the cutting-teeth.

In setting the cutting-teeth the slot D will tool at right angles to the length of the saw against the side of the saw, so that the projections at a a will come flat against it,and then the tool will be moved along the saw-blade with the end of the screw 72 in line with the points of the teeth, which will indicate the degree of set of each cutting-tooth. In this manner it will be seen that with this tool and a file a saw can be easily and accuratelyfitted; and the tool is adapted also for use as a screwdriver,measure, and hammer, so that the tool is very useful, and it is at the same time cheap and durable.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. The combination, with the body A of formed with the loop f for holding a file, substantially as and for the purposes set forth.

3. The body A,f0rmed with side flanges, d, in combination with the plate F, having slot k, substantially as set forth.

4. The body A, formed with flange i 2", in combination with plate F, formed with loop f, for holding a file, substantially as and for the purposes set forth.

5. The combination-tool herein shown and described, consisting of the body A and adj usting-plate F, the body formed with flanges d, screw-driver B, hammer 0, slot D, graduations c d, recess f, projections a b, the latter having set-screw b, the plate F being formed with the slot hand loopf, substantially as and for the purposes set forth.
