' Application October 12, 1950, Serial No. 189,716
The object of our-present invention is to devise novel blade clamping devices, and, while particularly designed for clamping safety razor blades in position for cutting or scraping, the invention is not limited to such type of blade but can be used with any desired construction of blades adapted to be held between two clamping jaws.
A further object of the invention is to devise a novel construction and arrangement of two clamping members having tangs extending from their clamping jaws, one tang being insertable through the other tang, and the tangs exerting a spring clamping action against each other to clamp in position between the jaws a scraping or cutting blade.
A further object of the invention is to accurately position a blade in clamping position and provide means to facilitate the insertion of the tangs into a handle.
With the foregoing and other objects in view as will hereinafter clearly appear, our invention comprehends novel blade clamping mechanism wherein two clamping members have a novel construction and arrangement of tangs to effect the clamping of a blade between the jaws of the clamping mechanism.
It further comprehends a novel construction of clamping jaws or plates having blade positioning means and gripping means.
For the purpose of illustrating the invention, we have shown in the accompanying drawings preferred embodiments of the invention which we have found in practice to give satisfactory and reliable results. It is, however, to be-understood that the various instrumentalities of which the invention consists can be variously arranged and organized and the invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.
Figure 1 is a perspective view of blade clamping devices, embodying our invention.
Figure 2 is in perspective an exploded view of certain of the component parts showing the manner in which the blades are assembled.
Figure 3 is a top plan view.
Figure 4 is a section on line 4-4 of Figure 3.
Figure 5 is a side elevation of the clamping jaws.
Figure 6 is a perspective view of a portion of another embodiment of the invention, showing the clamping jaws as adapted to receive a different type of blade of the single edge type.
Similar numerals of reference indicate corresponding parts.
2 Claims. (01; 30-332) Referring to the drawings:
The blade clamping mechanism has two clamping members I and 2 respectively. The clamping member I has a clamping jaw :3 in the form of a plate having any desired contour, and, as shown, the clamping jaw is substantially rectangular. The clamping member 2 has a similar clamping jaw or plate 4, and these clamping jaws have flat inner faces to receive between them a blade 5 adapted for scraping or cutting. This blade in Figures 1 to 5 inclusive is shown as a safety razor blade of the double edge type.
Positioning and aligning means are provided for theblade 5 and for a double edge blade consist of two spaced dowel pins 6 fixed in one clamping jaw and apertures I in the other clamping jaw to register with the dowel pins.
The blade I has a tang 8 of less diameter than its blade and inclining outwardly and rearwardly from its blade. The tang 8 at its forward end portion curves downwardly to merge with its clamping jaw. The tang 8 has intermediate its ends a clearance opening 9 having any desired contour for its intended purpose and shown as rectangular.
The clamping jaw 2 has a tang lil connected to it by a downwardly curved neck H of less diameter than the jaw 2 and adapted to fit the opening 9 in the jaw I. The neck ll. connects with an intermediate portion l2 wider than the neck and having shoulders 13 and M at its forward portion which form fulcrums for the spring clamping action of the clamping jaws. When the tangs are pressed together they are insertable into the slotted, steel ferrule [5 of a grasping handle l6. To facilitate such insertion of the tangs into the handle, the clamping jaws may be provided with opening IT to provide a better grip of a finger and thumb of the user during such operation.
In the embodiment seen in Figure 6, the construction is the same as in the other figures except that the clamping jaws, instead of being provlded with dowel pins and apertures for positioning a double edge blade, are provided with grooves I8 and 19, respectively, extending across the jaws to receive the heel of a single edge razor blade and position it between the clamping jaws so that its scraping or cutting edge is presented exterior of the jaws. The forward edges of the clamping jaws are preferably beveled for clearance with the work.
In the operation, the scraping or cutting blade is positioned between the clamping jaws, the clamping members being assembled as shown,
the tangs pressed together and inserted into the handle. The shoulders 13 and [4 of the tang I0 press against the tang 8 to move the clamping jaws towards each other.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
1. A blade clamping mechanism, comprising a pair of clanipifigfifirfibers consisting of afir's't and a second mn'n'be'r,each member having a clamping jaw with a substantially fiat inner face to receive a blade and having a tang offset to wards the flat inner face of each jaWpthe-ta-ng of the first member having near its jaw a neck and shoulders at the outer erid bfthe' rieck; the
tang of the second member having an opening through which the tang of the firstmember ex tends with its shoulders overlying the opening and contacting the inner face of the tang of the first member to cam the jaws together when the tangs are pressed towards each 'other,-$md a handle into which the tangs are insertedwfien 4 pressed towards each other to effect the clamp ing action of the jaws.
2. The construction defined in claim 1, wherein the jaws have openings forming gripping portions for the thumb and finger to facilitate the insertion of the tangs into the handle.
