SKIVING TOOL Filed March 17, 1953 SKIVING TOOL Max Pill, Pomona, Calif.

Application March 17, 1953, Serial No. 342,910

7 Claims. (Cl. 30-283) This invention relates to a tool to skive leather and similar materials.

An object of the present invention is to provide a skiving tool embodying novel blade-mounting means enabling quick, safe and easy attachment to or removal of a blade.

Another object of the invention is to provide a skiving tool in which the blade is held under resilient flexure to conform it to the support frame over which it is so held.

A further object of the invention is to provide, in a skiving tool, adjustable gauge means to enable variation in the depth and/ or angle of the skiving cut of the blade of said tool.

The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

Fig. 1 is a front elevational view of a skiving tool according to the present invention.

Fig. 2 is a side elevational view thereof with the handle broken away.

Fig. 3 is an end view of the tool as in Fig. 2.

Fig. 4 is a longitudinal sectional view as taken on line 4-4 of Fig. 1.

The skiving tool that is illustrated comprises, generally, a handle 5, a support plate 6 across one end of the handle and against which a blade 7 is adapted to be pressed, resilient means 8 to engage the ends of said blade to resiliently press the latter against support plate 6, and a gauge 9 adjustably carried by the handle and operatively associated with an end of the support plate to vary the depth and/or angle of the skiving cut performed by the tool.

The handle is formed of a length of preferably squaresectioned rod bent at one end 10 to form sides 11 which are spread apart at the end opposite to end 10 and are somewhat closer together adjacent the latter end to accommodate the hand. At their free ends, sides 11 are angularly bent as at 12 out of the general plane of the handle.

The support plate 6 spans between side ends 12 and is permanently connected at its ends to said ends 12. As shown particularly in Fig. 3, plate 6 is transversely convexly bowed and is formed with a bend 13 to forwardly offset its blade-supporting portion 14 with respect to portion 15 thereof. An elongated opening 16 extends across the plate 6 and is so located that one portion thereof is formed in portion 14 and the other in portion 15. Because of the transverse bow in plate 6 and the bend 13 therein, the

portions

14 and 15 are quite inflexnited States Patent 0 2,735,180 Patented Feb. 21, 1956 ible although only the ends of the former portion are connected to handle ends 12, as shown in Fig. 2, wherein it is seen how the main portion of the handle extends angularly away from said portion 15. Along its upper edge, plate portion 14 is provided with stop blocks 17 that serve as position-limiting abutments for blade 7. Said blocks are located with respect to slot 16 and bend 13 according to the width of blade 7 to bring the cutting edge 18 thereof slightly above said bend when said blade is located with the opposite edge 19 against said blocks.

The blade 7 preferably comprises an elongated member of rectangular form, the one shown being the blade used in the Schick repeating razor. Since such blade can be obtained in the open market, the same is, therefore, quite inexpensive as compared to specially made blades.

The resilient means 8 is carried by each handle side 11 and, except for being oppositely formed on each side, is the same on both sides. Each said means comprises a generally C-shaped clip member 20 fitting over each end 12 and of suflicient front-to-back depth to slide laterally relative to said ends, as shown more clearly in Figs. 2 and 3. Each member 20 has a side wall 21 that connects a front wall 22 and a back wall 23. A guide wall 24 extends from wall 23 parallel to wall 21 and in a direction toward wall 22.

Walls

21 and 24 are spaced to slidingly fit over end 12, while

walls

22 and 23 are spaced to allow for the mentioned sliding movement of member 20.

A resilient arm 25 fixedly extends from each wall 24 and is connected to each respective handle side 11 as by an end 26 thereof extending into a hole provided in each said side 11. Thus, each member 20 is carried on the free end of arm 25 and the latter constitutes a spring means that is normally biased or tensioned in a direction to cause wall 22 of said member to resiliently press against plate portion 14 where the latter is connected to handle ends 12.

From the foregoing it will be clear that the walls 22 normally press the ends of blade 7 to flex the latter over the curvature of plate portion 14 in the manner shown, and that, by pressing walls 23 of members 20 forwardly or to the left, as shown in Fig. 2, the blade is released for replacement.

The gauge 9 is adapted to be removably attached to either handle side 11, as desired, thereby enabling tilting of the tool to proper position by both rightand lefthanded users. As shown, said gauge comprises a member 27 held in general alignment with one or the other handle side 11 by a spring clip 28 that frictionally and slidably engages the side 11 to which applied.

The upper end 29 of member 27 is forwardly offset so as to be forward of plate portion 15 and so that one of several notches 30, formed in said end 29, is engaged with the lower edge 31 of portion 15. Since gauge 9 can be slid along side 11, end 29 of member 27 can be adjusted to various amounts of forward protrusion relative to the cutter to, thereby, adjust the tilt or angle of presentation of the cutter edge 18. Such tilt is represented by line 32 of Fig. 3.

While I have illustrated and described what I now contemplate to be the best mode of carrying out my invention, the construction is, of course, subject to modification without departing from the spirit and scope of the invention. It is, therefore, not desired to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.

Having thus described the invention, what I claim and desire to be secured by Letters Patent is:

l. A skiving tool comprising, in combination, a handle having transversely spaced generally parallel ends, a blade-supporting plate affixed to and spanning said ends,

means to clamp a blade to said plate, and a tool-tilting gauge adjustably carried by one of said handle ends and limited by engagement with the support plate to vary the angle of presentation to a piece of work of the blade.

2. A skiving tool comprising, in combination, a handle having transversely spaced generally parallel ends, a blade-supporting plate atfixed to and spanning said ends, means to clamp a blade to said plate, and a tool-tilting gauge adjustably carried by one of said handle ends and limited by engagement with the support plate to vary the angle of presentation to a piece of work of the blade, said gauge being adapted to be removably mounted on each said handle end, selectively.

3. In a skiving tool having a handle and transversely spaced ends extending therefrom, the combination comprising a support plate aflixed to and spanning the space between said ends, the plate being adapted to support a cutting blade, a clip slidably mounted on each end, the clips being larger than said ends to provide lateral play between each clip and the respective end, the clips being slidable laterally for the reception of a cutting blade, and spring means for pressing the clips against the cutting blade in a direction to urge the blade toward the support plate.

4. In a skiving tool according to claim 3, in which the 25 support plate is curved between said ends for the support of a blade flexed lengthwise between said ends, and the spring clips being biased to hold the cutting blade in said flexed position.

5. A skiving tool comprising a handle having two spaced parallel ends, said ends being bent at an angle to the plane of said handle, a plate aflixed to and spanning said ends, said plate having at least one stop block against which a blade is adapted to be positioned, a pair of laterally movable clips fitting over each of said ends and engaging said blade, and a resilient member biased to hold each of said clips against said blade and said plate.
