SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed July 13, 1914. Serial No. 850,565.

To all whom it may concern:

Be it known that I, SAMUEL W. CHARLES, a citizen of the United States, and a resident of the city of Palo Alto, in the county of Santa Clara, State of California, have invented a new and useful Improvement in Safety-Razors, of which the following is a specification.

My invention relates to improvements in safety razors wherein the conjunction of a suitable extension of a razor guard with a similar extension of a razor blade pivotally mounted upon the extension of the razor guard permits the razor blade to be swung away from the guard and handle; and the object of my invention is to provide an improved safety razor wherein the blade may be readily swung away from the guard so that the blade and guard may be easily cleaned without removing the blade. 1 accomplish this by closed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, and in which Figure 1 is a front view of the safety razor with the blade disclosed in a closed position ready for use, showing a leaf spring secured to the upper edge of the guard an arranged to engage blade for the purpose of retaining the said blade in a closed position and the serrated edges of the guard extending below the edge of the razor. Fig. 2 is a view similar to Fig. 1 except that the blade is disclosed in an open position swung awa from the guard and disclosing the manner in which the said blade is retained in such position by means of the leaf spring which engages one of the rectangular extensions on the said blade. Fig. 3 is a side elevation of Fig. 1 disclosing the manner in which the blade is pivotally and detachably secured to the guard and held adjacent thereto, and Fig. 4: is an enlarged detailed sectional view taken on line X-X of Fig. 1 of the drawings in the direction indicated by the arrow, disclosing the manner in which the razor blade is pivotally and detachably secured to the guard.

Referring to the drawings, the numeral I is used to designate a suitable handle to the end of which is rigidly secured in any suitable manner, the guard 3.

The numeral 5 is used to indicate a recmeans of the device d1s-' razor blade 9 is pivotally mounted upon the the upper edge of the tangular extension at the upper edge of the said guard 3.

A leaf spring 6 is secured by means of the pins 7 to the upper edge of the guard 3 and at right anglesthereto, the end 8 of the leaf spring 6 being free to move, the purpose of which will hereinafter be more fully de scribed.

A razor blade 9 is provided with a rectangular extension 10 which is arranged to coincide with the rectangular extension 5 of the guard 8. To the extension 5 of the guard 3, adjacent'to the free end 8 of the leaf spring 6, is detachably secured a bolt 12, which is provided with a reduced threaded portion 14 adapted to be engaged by a suitable thumb nut 15 on the opposite side of the said extension 5, so that the said bolt 12 may be rigidly secured to the extension 5 of the guard by means of the said nut 15. The rectangular extension 10 of the bolt 12, so that when the said blade 9 is in the position illustrated in Fig. 1 of the drawings, the leaf spring 6 will lie along the upper edge of the razor blade 9 and the extension 10 thereof. The uper edge of the razor blade 9 is provided with a shoulder or recessed portion 16, which provides a recess into which a finger may be inserted for the purpose of opening the blade 9 when the said blade9 is closed, as shown in Fig. l of the drawings.

The razor is used in the ordinary manner and after shaving the operator may read ily and easily clean the blade 9 by rotating the same on the bolt 12 secured to the extension 5 of the guard 3, until the said blade 9 assumes the position disclosed in Fig. 2 of the drawings. The blade 9 is retained in this position by the tension of the free end 8 of the leaf spring 6, which rests against the flat surface of the extension 5, secured to the bolt 12.

By referring to Fig. 1 of the drawings, it will be observed that when the razor blade 9 is in a closed position that the leaf spring 6 will engage the upper edge of the said blade 9, while the free end 8 of the said leaf spring 6 will engage that portion of the extension 10 beyond the pivot formed by the bolt 12 and retain the upper edge of the blade 9 against the inner edge of the leaf spring 6. The blade 9 may be detached for replacing the blade with another one by unscrewing the thumb nut 15 from the reduced portion 14 of the bolt 12, the said bolt 12 may then be withdrawn from the extension 5 of the guard 3 and the razor blade 9 removed and another one secured in place thereof. The length of the unthreaded portion of the bolt 12 is slightly greater than the thickness of the extension 10 of the plate 9 in which case, when the said bolt 12 is drawn tightly onto the extension 5 of the guard 3, the razor blade 9 will be free to rotate on the said bolt 12 and will be held in position by means of the tension of the free end 8 of the leaf spring 6.

It is obvious from the foregoing that I have provided a simple, cheap and practical safety razor, wherein the blade may be easily and readily detached and moved to an open position for cleansing purposes, and have also provided means whereby the blade will be eifectively retained in an open or closed position.

Having thus described my invention what I claim as new and desire to secure by Letters atent is 1. A safety razor comprising a suitable handle; a guard secured to the handle and having a rectangular extension on the upper edge thereof; a razor blade having a rectangular extension coinciding with the extension on the guard and pivotally mounted upon, the rectangular extension of the guard; and a leaf spring secured to the upper edge of the guard and adapted to engage the upper edge of the extension of the blade.

2. A safety razor comprising a suitable handle; a guard secured tothe handle and having a rectangular extension on the upper edge thereof; a razor blade having a rectangular extension thereon arranged to coincide With the extension on the guard; a leaf spring secured to the upper edge of the guard and arranged to engage the upper edge of the blade and the extension thereon and to retain the coincidence of the blade and the guard; and means adapted to de tachably and-pivotally secure the razor to the guard.

3. A safety razor comprising a suitable handle; a guard secured to the handle and having a rectangular extension on the upper edge; a razor blade having a rectangular extension thereon arranged to coincide with the extension on the guard; a leaf spring securedto the upper edge of the guard and arranged to engage the upper blade and; one of the extensions thereon and to retain the coincidence of the blade and the guard; and a bolt detachably secured to the guard and adapted to pivotally engage the blade and retain the said blade on the guard.

4. A safety razor comprising a suitable handle; a guard secured to. the handle and having a rectangular extension on the upper edge thereof; and a razor blade having a rectangular extension coinciding with the extension on the guard and pivotally mount.- ed within the coinciding extension on the guard.

In Witness whereof I have hereunto set, my signature in the presence of two, subscribing witnesses this 6th day of July, 1914 SAMUEL W. CHARLES. Witnesses M. O. Honcns, I G. CHARLES HGDGES.
