SAFETY-RAZOR.

Specification of Letters Patent.

Patented July 24], 1915..

To all whom it may concern:

Be it known that 1, WILLIAM F. Gnosoriorr, a subject of the Emperor of Germany, residing at Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Safety- Razors, of which the following is a full, clear, and exact description.

This invention relates to an improvement in safety-razors, but more particularly to an improved arrangement of latches arranged to secure the cutting-blade in position on the frame and to hold the cover-plate of the razor-frame firmly closed, the loweredgeiof the plate contacting with the cutting-blade adjacent the cutting edge thereof. Y

The latches above referred to are secured to the cover-plate and move with it, said latches being arranged to engage both the bodiment of theinvention,

top-plate of the frame and the heel of the cutting blade.

These being among the objects of the present invention, the same consists of certain features of construction and combination of parts to be hereinafter described and finally claimed with reference to the accompanying drawing, illustrating a suitable emin which- Figure 1 is a top plan view of a razor frame embodying my improvement; the cover-plate being in open position; Fig. 2 is a similar view of another embodiment of my invention; Fig. 3 is an enlarged crosssectional'view of the form illustrated in Fig. 1, the section-being "taken on a line 3-3 in Fig. 1, the cover-plate being closed; and Fig. 4 is an enlarged fragmentary sectional view of the form of device illustrated in Fig. 2, the section being taken on a line 4.4 in Fig. 2, the cover-plate also being closed.

Referring to the'drawing, arsafety razorframe is indicated'by 1 consisting of a body portion 2 carrying a guard 3 which holds the blade 4. The guard 3 is provided with the usual stops 5 and 6 for the blade 3. i

The invention consists chiefly of an arrangement of latches to securethe blade 4:

in posltion and to hold the pivotal coverlate 7 in closed position as shown in Fig. 3. The cover-plate 7 is pivotally secured to the uard 3 as at 8 and 9 and contacts with the blade 8 adjacent the cutting edge 10 of the blade- The cover-plate 7 is provided cover-plate under tension.

with an inwardly projecting edge 11 which edge bears against the blade as shown in Fig. 3.

To hold the cover-plate 7 in closed position and to hold the blade 4 down against the stops 521ml 6, I provide a resilient looking member 12 which is firmly secured to the inner surface of the cover-plate 7. The locking member 12 consists of a resilient tongue or projection 13 carrying an auxiliary resilient tongue or projectionl l, the tongue lfbeing preferably struck out of the tongue 18. The function of the tongue 14 is to perform the dual rele of holding the blade 4 down and to hold the coverplate 7 closed, while the tongue 13 gives to the locking member, as a whole, the proper spring or resilient action.

7 As can be seen in Fig. 3, the locking mem ber' 12 is'arranged or located to pass under the upper portion of the body 2 of the frame, and to permit of such passage I provi'de'the frame or body 2 with a slot or opening 15 through which the locking member 12 will pass.

To cooperate with the lock 14, to secure the cover-plate in closed position, I provide the body 2 with a struck down projection-16 which will engage a recess 17 in the tongue or lock'll when the cover plate is closed. lVhen in the closed position the tongue or lock 14 will bear upon the heel 18 of. the cutting bla-de, as shown in Fig. 3. fhe is provided with a projecting portion '19, by which means the said coverplate'can be swung outwardly and opened.

When the cover-plate 7 is in the open position,ithe locking member 12 will be positioned slightly out of alinement with the under surface 20 of the frame; that is to say, it will be located slightly above the line of said under surface; hence when the coverplate is closed, the lip 21 of the locking member 12 will strike the upper edge of the opening 15 and a continued closing movement of the cover-plate will cause the looking member 12 to springdownwardly, whereby the said locking member (is placed When-the socket 17 in the tongue 14 alines with the projection or keeper 16, it will snap into place and at such time the freeend 22 of said tongue will bear upon the heel 18 of the cutting-blade. When the cover plate is forced inwardly and closed the tongue 14 will be placed under tension as soon as it contacts with the heel of the cutting-blade. of the tongue 14 and heel of the cuttingblade adds greatly to the locking efiiect of the keeper 16 and recess 17 in the tongue 14.

In the embodiment of my invention illustrated in Figs. 2 and l, the resilient locking member 23 is provided with the auxiliarywith a recess 26 which engages tongue 2% carrying a supplemental tongue 25. In this form the tongue 25 is provided the projection or keeper 16, while the auxiliary tongue 24 bears upon the heel 18 of the cutting blade. The action of this latter form of locking means is substantially the same as the action of the locking means 12.

In both forms of my invention the resilient tongues bear upwardly upon the razor-frame and downwardly on the cutting-blade.

Having now described my invention what I claim and desire to secure by Letters Patent is:

p l. A safety-raZor-frame, comprising a bodyv portion, a guard carried thereby adapted to support a cutting-blade, a coverplate for said blade pivotally secured to said frame, a locking device carried by said cover-plate consisting of a resilient projectin'g'member adapted to engage said frame, and an independentl-y'acting resilient tongue carried by the projecting member adapted to bear upon the heel of the cutting-blade, the said tongue being substantially in the same plane with the projecting member.
