United States Patent SAFETY RAZOR Angelo Anastasia, Monterey, Calif.

Application April 16, 1954, Serial No. 423,715

2 Claims. (Cl. 30-605) This invention relates to a safety razor and has for its primary object to releasably hold a razor blade in the head of the safety razor without requiring the use of screw threads or the like in the razor construction.

Another object is to resiliently hold the movable clamping jaws of the safety razor in clamping engagement with the blade thereof and at the same time facilitate the rapid opening of the jaws for permitting the interchanging of the blades of the razor.

Another object is to releasably hold the jaws out of clamping engagement with the blade during the interchanging of the blades.

A still further object is to afford adjustment of guards relative to the cutting edges of the razor blade and to enable guards of different types to be employed.

The above and other objects may be attained by employing this invention which embodies among its features in a safety razor of the type having stationary blade supporting jaws and blade clamping jaws carried by the stationary jaws for movement about parallel axes adjacent the edges of the stationary jaws, a plunger movable between the stationary jaws and operatively connected with the movable jaws for moving the movable jaws into clamping engagement with a safety razor blade mounted on the stationary jaws, and a spring engaging the plunger to yieldingly advance it away from the stationary jaws to hold the movable jaws into clamping engagement with a razor blade supported on the stationary jaws.

Other features include a push button for moving the plunger against the efiort of the spring to open the clamping jaws and facilitate the changing of razor blades, and releasable means for holding the plunger advanced against the effort of the yielding means.

In the drawings:

Figure l is a perspective view of a safety razor embodying the features of this invention;

Figure 2 is a top plan view of the razor illustrated in Figure 1;

Figure 3 is a transverse sectional view taken substantially on the line 3-3 of Figure 2;

Figure 4 is an end view of the razor showing the blade clamping jaws open; and

Figure 5 is a fragmentary perspective view of a mod].- fied form of guard.

Referring to the drawings in detail, a tubular handle is provided adjacent one end with an interior shoulder 12 and carried by the adjacent end of the handle are outwardly extending stationary blade supporting jaws 14 carrying adjacent their outer ends depending arms 16 in which are pivotally supported movable blade clamping jaws 18 which move in intersecting arcuate paths about spaced parallel axes on opposite sides of the handle 10. The structure so far defined is conventional with certain types of safety razors in which the blades are interchangeable without separating the head from the handle.

Mounted for longitudinal sliding movement through the interior of the handle 10 is a plunger 20 carrying adjacent its end which projects through the end of the handle 10 adjacent the stationary jaws 14 with a cross head 22 which is operatively connected to the movable jaws 18 so that as the plunger moves longitudinally within the handle 10, the jaws 18 will be moved about the spaced parallel axes previously referred to. Carried by the plunger 20 and extending through the end of the handle 10 remote from the stationary jaws 14 is a push ice button 24 having an annular groove 26 extending therearound which defines a shoulder 28, the purpose of which will hereinafter appear. Pivotally mounted as at 30 in the handle 10 adjacent the end thereof remote from the stationary jaws 14 is a latch 32 having a tongue 34 WhlCh is urged toward the push button 24 under the mfluence of a torsion spring 36 so that when the push button is pressed inwardly relative to the handle, the tongue 34 will engage the shoulder 28 to hold the cross head 22 projected beyond the opposite end of the handle 10. Extending through the plunger 20 intermediate the ends thereof is a cross pin 38, and surrounding the plunger 20 between the cross pin 38 and the shoulder 12 1s a compression coil spring 40 which exerts yielding pressure on the plunger 20 in a direction to hold the movable clamping jaws 18 in clamping engagement with the razor blade B resting on the stationary jaws 14. It will thus be seen that the razor blade B will be clamped in place under the influence of the spring 40 and cannot be released until pressure is exerted on the push button 24 to move the plunger 20 against the effort of the spring 40 and the jaws 18 about the spaced parallel axes.

Carried by the movable jaw members 18 and extending outwardly from opposite ends thereof in substantial parallel relation thereto are supporting sleeves 42 carrying set screws 44 which extend into the sleeves 42 in perpendicular relation thereto. In one form of the invention a guard designated generally 46 comprising a supporting bar 48 carrying adjacent opposite ends arms 50 is mounted on each jaw 18 by entering the arms 50 into the sleeves 42 and tightening the set screws 44 to hold the bar 48 at a selected distance from the edge of a razor blade clamped between the jaws 14 and 18. In this type of guard the bar 48 is provided between the arms 50 with roller disks 52 which serve as guards for the adjacent edges of the razor blade B and owing to the fact that they are rollers, the gliding of the razor over the face is facilitated.

A modified form of guard designated generally 54 comprising a solid guard bar 56 carrying outwardly extending arms 58 may be employed in place of the guard 46 by extending the arms 58 through the sleeves 42 and securing them therein by set screws 44.

In use, it will be evident that the clamping jaws 18 will be held in clamping relation to the stationary jaws 14 under the influence of the spring 40 and when it is desired to insert or remove a razor blade B from the razor, pressure is exerted on the push button 24 to move the plunger 20 against the elfort of the spring 40 and the clamping jaws 18 in the position illustrated in Figure 4. With the jaws 18 in this position, a blade B within the razor may be readily extracted and a new one substituted therefor and upon exerting pressure on the latch 32, it will be moved against the effort of the torsion spring 36 to extract the tongue 34 from the groove 26 and move it out of engagement with the shoulder 28 to enable the plunger 20 to move under the influence of the spring 40 and close the clamping jaws 18 on the blade to clamp it against the supporting jaws 14.

From the foregoing, it will be obvious that the blade may be easily and quickly removed from the razor and a new blade substituted with but a minimum of elfort on the part of the user.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

1. In a safety razor of the type having a tubular handle, stationary blade supporting jaws carried by the handle and extending laterally outwardly therefrom adjacent one end thereof, blade clamping jaws carried by the stationary jaws for movement about parallel axes adjacent the edges of the stationary jaws remote from the handle from an inactive position in which they extend outwardly from the stationary jaws to an active position in which they overlie the stationary jaws, a plunger mounted in the handle for movement longitudinally therethrough, means carried by the plunger and operatively connected to the blade clamping jaws for moving them to inactive position when the plunger is advanced toward the end of the handle remote from the stationary jaws, means for moving the plunger away from the stationary jaws and the movable jaws into clamping engagement with a blade supported on the stationary jaws comprising a spring carried by the handle in surrounding relation to the plunger and operatively engaging said plunger for yieldingly advancing it toward the end of the handle remote from the stationary jaws, a. push button carried by the plunger and extending through the end of the handle remote from the stationary jaws, said push button having an annular shoulder intermediate its ends, and a spring advanced manually releasable latch carried by the handle for engaging the shoulder and holding the plunger advanced toward the stationary jaws and the movable jaws open against the effort of the spring.
