SAFETY-RAZOR.

Specification of Letters Patent.

Patented June 4, 1907.

Application led August 10, 1906. Serial No. 329,965.

To all whom zit-may concern.:

Be it known that I, JOHN J .'MEEHAN, a citizen of the United States, residing at 1754 Lawrence street, in the city and county of Denver and State ofl Colorado, have invented certain new and useful Improvements in Safety- Razors; and I do declare the following to be a full, clear, and exact description of the in.

vention, such as willenabl others skilled in. the art to which it appertains to make and use the same, reference being had to the aocompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in safety razors of the class set forth in .my application, Serial No. 261,764, iiled May 23, 1905.

My present invention relates to certain improvements in the detail/s of construction, though the general construction, as well as the principle of operation, remain the same as set forth in the original ap lication.

The general construction o the device includes a guard com osedI of two distinct members, together with means for laterally separatingthe members, whereby more or less of the edges of the double edged blade may be made available for cutting purposes. The invention is also of suiiicient scope to include a blade composed of two laterally adjustable members used in connection with a stationary guard, since the same rinciple of operation may be employed to 'lfaterally adjust the blade members, giving the same results'attained by the lateral separation or bringing together of the guard members. In the drawing, however, the divided guard is illustrated as it is believed to be the preferred'form of construction, but it must be understood that the invention is not limited thereto. Y

Having brieily outlined my im roved construction, I will proceed to descri e the same in detail, reference being'made to the accompanying drawing, in which is villustrated an embodiment thereof.

In this drawing, Figure 1 is a view illustrating my improved safety razor with all the parts assembled. Fig. 2 is a similar view as seen from the opposite side. Fig. 3 is a view with the backing late and the handle on the corresponding si e removed, exposing the blade and a portion of the guard. Fig. 4 is a cross-section taken on the line 4-4, Fig. 1. Fig. 5 is a longitudinal section taken through the guard plate. A Figs. 6 and 7 are cross-sections taken on the lines 6-6 and 7 7 respectively, of Fig. 1..

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the handle, which is composed of two

parts

6 and 7. The part 7 of the handle is provided with an extension 7A, which engages the guard on one side. The blade 8 engages the guard on the opposite side from the handle part 7A;

while the bladejis held in place on the guard by a backing plate 9.

enter a' counterpart recess formed in the handle member 6, the extension I 9A being beveled to hol'dit in place wheninserted, except by movement 1n the reverse direction from'that in which it entered the recess. The edges of this projection are beveled to extend underneath the edges of the recess as indicated by dotted lines in Fig. 1. The extremity of the backing plate opposite the projection 9A is provided with a hook shaped part 9B, which is also beveled to engage a counterpart recess formed inthe handle extension 7A. The hook 9B passes around one end of the blade 8. TheA backing plate is held in place by the two parts 9A and 9B, Which fit tightly into their respective recesses in the respective handle members. At the same time the backing plate is readily removed by a longitudinal movement, whenever it is desirable to remove the blade. The blade is further held in` place by small studs This backing plate is provided witha projection 9A, adapted to 10, with which the handle extension 7A is provided. These studs project between the two members of the guard, the latter being recessed on opposite sides of the studs, so that the studs shall not interfere with the closing movement of the guard members.

The guard is composed of two members 12, with which the blade 8 is in contact on one side, asheretofore explained. The portion of these guard members engaged by the blade is provided with teeth 12A or'opposite sides, since the blade 8 is providediwith two cut.- ting edges which when the razor is in use are interchangeablefsince either may be used at pleasure. Thei'guard is further provided with extensions 12B, which are located between the handle members and are provided IOO with inclined slots 12C, through which project small pins or studs 13, with which-.the handle member 7 is provided. The toothed parts of the guard are also rovided with 'inclined slots 12C, through W ich pass small pins'lS. rThese slots are arranged and inclined as shown in the drawing, whereby when the guard members are moved longitudinally in one direction, they are caused to separate or move away from each other laterally; Vwhile when they are'moved longitudinally in the opposite direction, they are caused to approach each other laterally, whereby the guard is so regulated that the outer edges of the blade shall be-nearer or farther away from the outer extremities of the teeth of the guard. l

Near the extremity of the handle extensions of the guard members, each member is provided with a recess 14, the two recesses together forming a sort of socket for the head 15 of an adjusting screw 16, to which is applied a milled nut 17,.which passes through o enings 18 formed in the handle members, t e opposite edges of the nut protruding from the handle members whereby the nut is accessible to the user for purposes of adjustment. By turning this nut, it is evident that the screw will be moved longitudinally in one direction or the other, according tothe direction in which the nut is turned. If the nut is turned to move the screw toward the right, referring to Figs. 1, 2 and 3 of the drawing, the guard members will be moved in a corresponding direction and will be made to a proach each other by virtue of the inclined slots formed in the guard members and engaged by the pins of the handle member, as heretofore described. While if the nut is turned to move the screw toward the left, the guard members will be separated laterally by virtue of the inclined slots and pins, as will be readily understood. It will of course be understood that the nut 17 is retained by the handle andprevented from movement longitudinally on the shank of the screw. This being the case, as the nut is turned the screw will be moved longitudinally in the one direction or the other, for the pupose heretofore explained. l

hen the parts are assembled, the two handle members are connected by screws 19. From the foregoing description the use of my improved device will be readilyunderstood. Assuming that the arts of the device are assembled and the b ade in position, it is only necessary to rotate the screw 17, in order to adjust the guard members laterally, so that the outer extremities of their teeth shall be nearer or farther away from the edges of the cutting blade. ready for use. After shaving the backing plate may be quickly removed by placing the thumb upon the `roughened part 9C thereof and moving the latter longitudinally The device is then' toward the left, referring to Fig; 1. The

blade may then be lifted off from the studs.

members longitudinally, whereby they are` given a lateral movement toward or away from each other, as' may be desired.
