COMBINATION MAT CUTTER AND BEVELER Filed Jan. 29, 1932 van@ lima-4 INVENTOR MLU/7M d/V-CQNN Patented May 16, 17933 UNITED STATES WILLIAM J. MCCANN, oF LAKEWOOD, omo

COMBINATION MIAT CUTTER A ND BEVELER Application filed January 29, 1932. Serial No. 589,650.

This invention relates to a beveling tool for cutting a beveled edge or straight edge on mounting boards, 1mats and the like.

One object being to provide a smooth and 5 even cut either on a beveled edge or straight edge.

Another object being to provide a setting screw and guide which permits an accurate setting of the cutting blade at any desired angle.

Further advantages may be noted from the following description and accompanying drawing, in which Figure 1 is a perspective View 0f the cutting and beveling tool in operation; Fig. 2

is a sectional view of the guide with the cutting and beveling tool in elevation and set at a 60 degree angle; Fig. 3 is a front elevation; Fig. 4 is a rear elevation partly in section;

Fig. 5 is a perspective view of the rear; Fig. 6 is a modilication of the manner in which the cutting and beveling tool is slidably mounted upon the guide.

Referring specifically to the drawing, the

cutter and beveler consists of a handle 10 with a shoulder which connects with a flat flange or plate 11 at its lower end, a pivot pin 12 with a lock washer 13, screw head 14 and a flat cutting blade 15 held or locked between the flatlange 11 of the handle 10 and a hinge plate 16, the lower end of which forms a tube 16a through which the pin 17 extends. The pin 17 has a head 18 at one end and is threaded at the other end.

An adjusting screw nut 21 with notches 22 for setting the degree of angle is screwed on the threaded end of the pin 17 and locks the cutter and beveler at the angle desired by screwing the nut against the side wall 2O of the guide bed 19. s

The underside of the guide bed 19 Imay be so constructed as to form a T 23 as shown in Fig. 2, or a modified form 23a, as shown in Fig. 6, or any similar form may be used,

the guide 24 may be constructed of a wood or metal core A with a metal binding B and groove C as shown in Fig. 2, or itv may be constructed entirely of wood with a groove I) as shown in Fig. 6. The grooves are cut in the manner shown to facilitate the sliding of the cutter and bevelerbed in the guide.y

By'pivoting the handle 10 on the pin 12 to the desired position on the mat board 25 and tightening the screw head 21, a clear accurate cut or bevel may be attained by drawing the cutter and beveler along the groove in the guidethe distance required to make the cut or bevel. Y Either an inside or outside cut or bevel may be made.

It is to be `understood that I do not limit myself to the exact design and arrangement of the parts shown in the accompanying drawing and described above, for it is evident that I may make various changes without eX- 05 ceeding the scope of the appendedclaims.

I claim:

1. A combination mat cutter and beveler comprising a guide strip provided with a beveled edge, a bed having a sliding engage- 7 ment with said edge and movable along the same, a blade holder andhandle hinged to K the lower edge of the bed, a blade and means to clamp the blade in the holder with its edge projecting beyond the same, and below the guide, said means comprising a pivot at a right angle to the axis of the hinge, permitting the handle'and blade to be tilted to apply the corner of the blade to the mat.

2. The combination stated in claim 1, said 30 clamping means and said pivot comprising a screw connecting the bladey holder to the hinge. e

In testimony whereof, I do alliX my signature.

WILLIAM J. MoCANN.
