OTTO KAMPFE, OF BROOKLYN, NEW YORK.
SPECIFICATION forming part of Letters Patent No.
788,836, dated May 2, 1905.
Application filecl December 10,1903- Sarial No. 184,571.
To all whom, it 77mm concern:
Be it known that I, OTTO KAMPFE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Razors, of which the following is a specification.
My invention relates to razors, and more particularly to that class of razors in which the blade instead of being integral with the shank is removable therefrom.
My preferred form is illustrated in the accompanying drawings, in which similar reference-letters designate corresponding parts.
In the drawings. Figure 1 is a side view showing the blade in place. Fig. 2 is partially a side view and partially a cross-sectional view of the same construction shown in Fig. 1, showing the blade removed. Fig. 3 is a top view of the same, and Figs. 4, 5, and 6 represent a slightly-modified form. Fig. 7 shows a blade of a form especially adapted for use with the construction shown in Figs. 4, 5, and 6.
A represents a razor-handle of any suitable shape, and B a shank pivotally secured thereto and provided with whatIshall call a bladeholder O, which will preferably be integral with the shank.
The blade-holder O is shown as comprising a bottom or back portion 0 and side portions (1, extending upwardly from the back portion and preferably integral therewith. These back and side portions form what may be called a pocket or rest for the heel of the blade.
At the outer end of the blade-holder is provided an abutment 0 for the outer end of the blade D when the same is in place. This abutment 0 may vary to a great extent both in shape and construction, but will preferably be adapted to prevent sidewise or turning movement of the blade as well as to act as a stop for the end of the same, thus preventing endwise or longitudinal movement thereof. For example, in the form of device, shown in Figs. 1, 2, and 3 it comprises a stiff metal end piece provided at its upper end with two inwardly-extending lugs 0 0 The outer end of the blade when in position will evidently rest against the straight portion of the abutment, and the lugs o a will further tend to support said blade against any tendency to a sidewise or twisting movement.
In the construction shown in Figs. 4, 5, and 6 the abutment c is shown as comprising a piece of metal provided with a hole or aperture. In this latter case the outer end of the blade D may be provided with a pin, Fig. 7, adapted to engage with the aperture in said abutment and is, furthermore, slightly out out or provided with a recess d. This recess is adapted to receive the abutmento. In other words, the shoulder d", forming the upper limit of this recess. will rest upon the upper edge of the abutment, and consequently will tend to prevent any sidewise movement of the blade. Such sidewise movement may be prevented by a great variety of devices provided on the abutment or partially on the abutment and partially on the blade.
E represents a lockingdevice, shown as arranged at the inner end of the blade-holder and adapted to be brought at will into or out of engagement with the inner end of the blade D. As shown, it is pivoted at the point e and is swung on its pivot into or out of engagement with the blade. Preferably it will be so constructed that when it is in engagement with the blade it will both bear against the end of the same and also prevent any sidewise or turning movement thereof. This latter result may be accomplished in a variety of ways. For example, in the construction set forth in Figs. 1, 2, and 3 the locking device is provided at its inner end with two lugs or extensions adapted to overlap the inner end of the blade, the solid inner end of said locking device cotning in contact with the inner end of said blade, and thus insuring the outer end of said blade being forced into contact with the inner surface of the abutment 0 Preferably the inner end of the blade used in this construction will be slightly beveled or cut at an angle and the outer end of the looking device will preferably be similarly beveled or out at an angle, so as to insure a tighter closure.
In the construction shown in Figs. 1, 2, and 3 the locking device is furthermore provided with a downwardly-extending tongue or projecting central portion which extends substantially to the edge of the pocket of the bladeholder and which fits into a socket arranged intermediate the shank proper and said pocket, thus securing a firmer and more accurate adjustment of the parts. In the construction shown in Figs. 4 and 5 this downwardly-extending tongue or projecting central portion is cut off, as shown in Fig. 4, and the upper portionof the locking device is slit longitudinally for a short distance, thus allowing the edge of the blade to project through the same and to be gripped by the ends of the locking device. Of course this slit afiords resiliency to the two end portions of the locking device.
Of course my invention can be applied not only to actual shaving devices, but also to stropping and honing machines, and, in fact, to any devices for holding a blade.
What I claim as new is 1. The combination with a blade-holder of a blade supported thereon, an abutment for one end of said blade provided at one end of said blade-holder, and a locking device pivotally secured to said blade-holder and adapted to be swung into or out of engagement with the other end of said blade and provided with \means for preventing sidewise or turning movement thereof.
2. The combination with a blade-holder of a blade supported thereon, an abutment arranged at the outer end of said blade-holder adapted to support-the outer end of said blade, a locking device pivoted to the said blade-holder and bearing against the inner end of the blade proper to support the same, and means for preventing any sidewise or turning movement of said blade when said locking device is closed.
3. The combination with a blade-holder of a blade supported thereon, an abutment for OTTO KAMPFE.
