SAFETY-RAZUR.

Specification of Eetters latent.

A plication filed June as, 1969.

Patented 315, lllllth Serial. No. soaoae.

To all whom it may concern:

Be it lznown that l, Lronnr. D. Sermon, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Safety- Razors, of which the following is a speciiication.

This invention relates to safety razors, and

1 its'object is to provide blade locking means operated by the handle of the razor, which operation is easily efiected by a pressure on the handle which releases radial arms normally held in locking contact by a spring or other similar means, as will be more fully described in the following specification, set torth in the claims and illustrated in the drawings accompanying this specification.

Figure l is a perspective view of the improved. razor. Fig. 2 is a similar view but showing the razor reversed and the parts released and separated. 3 is a vertical sectional view. Fig. 4 is a sectional view of a modified construction. The present invention is-adapted to scour the immediate release of the razor blade by the separa'tidn oi the parts with a simple operation efiiected while in the hand of the user by simply pressing on the handle of the razor when in its reversed position, and

thereby releasing cross arms which may be turned so that they are free from their normal engaging means and the parts may then be separated.

The razor comprises the cap plate 5 sli htly curved longitudinally and having at either end, depending sides 6 with inner projections 7 and lugs 8, the projections and v lugs being adapted to engage notches 9 in an the ends of the blade 10 and notches 11 in the guard plate 12, the latter having the guard teeth 13 usual in this class of instruments. The guard plate 12 is also provided with a central stem 14: with a reduced portion 15 near its base and adapted to enter.

and play within the tubular handle 16. The stem is retained within the handle by a set screw 17 which engages a shoulder 18 as shown in Fig. .3. An outward pressure is given the stem by the s ring 19 confined between the inner end 0 the handle and the u per end of the stem. The stem and guard p ate are therefore free to move a short distance, but are normally pressed outward. 7

When the guard plate is placed upon the cap plate, so as to confine the blade between by Letters Patentis:

the two, and the guard plate is l-eld in place by means or the lug 8 which enters the notch. 11, there is no possibility of rotation of these parts and the handle with its cross arm 20 occupies a position similar to that shown in Fig. 2 but when pressure is plied to the handle, it is forced down upon the ganmd plate so that the cross arm 29 may be swung around to pass beneath the projections 7, where it is held by the beveled lower sides 21 of the projections which enter the notches 22 at the outer ends of the cross arm. The handle is then released and the pressure of a spring 19 is exerted to re tain the projection 7 in the notches of the cross arm and prevent its rotation, while pressure is also exerted by the spring to cause the guard plate, the blade and cap plate to be held together rigidly.

In the modified form shown in. Fig. 4;, the guard plate 23 carries a stem 2% which. fills the tubular handle 25 and makes contact with the interior of a cap 26 which is screwed upon the upper end of the handle so as to force the stem downward and cause the guard plate to exert a pressure on the blade 2! and cap plate 28. The handle in this form also carries the spring cross arm 29 which engages the inward projections 30 on the cap plate and are similar to those already described as being adapted to fit notches in the outer ends of the arm.

This razor is of few parts and very simple in construction. It may be operated by one hand and the parts quickly separated so that a new blade may be inserted when found desirable.

It is obvious that other modified forms may be adapted wherein a spring cross arm may be used in connection with the handle to exert a pressure to hold the guard plate against the cap plate so as to firmly confine the blade between same, without departin from the essential features above describe.

What I claim as new and desire to secure 1. In a safety razor, the combination with a cap plate having depending sides with inward projections and retaining means comprising lugs adapted to position the blade, of a blade with notches and a handle with a guard plate separable therefrom and locking means comprising a cross arm with u ward notched ends adapted to engage w1th and embrace projections on the under sides of the end faces of the inward projections on the depending sides and confine the blade between the cap plate and the guard plate.

2. In a safety razor, the combination with a cap plate having de ending sides with inward projections, a lade with notches, a guard plate with notches to pass over the projections, blade positioning lugs, a stem on the guard plate, a hollow handle to receive the stem, a cross arm at the lower end of the handle with notches in its outer ends to engage the end faces of the projections and a spring within the handle adapted to position the guard plate against the blade eeaaie blade positioning lugs, a guard plate with notches to pass over the rojections, a sten; on the guard plate, a ho low handle to re ceive the stemfa cross arm at the lower end of the handle with notches in its outer ends to engage the end faces of the projections and a screw cap adapted when screwed onto the upper end of the handle to engage with the upper end of the stem and position the guard plate against the blade and the ends of the cross arm against the end faces of the inward projections on thedepending sides. A

In witness whereof, l have hereunto set my hand this 24 day of June, 1909.
