Specification of Letters Patent.

Patented June 30, 1908.

Application filed October 4, 1907. Serial No. 395,880.

Be it known that I, LEONARD B. GAYLOR, a citizen of the United States, and a resident of the city of Boston, county of Suffolk, State of Massachusetts, have invented a new and useful Safety-Razor-Stropping Device, of

which the following is a specification, reference being had to the accompanying drawings, in whichp Figure 1 illustrates a plan v1ew; Fig. 2 illustrates a side view; Fig. 3 illustrates an end view; Fig, 4 illustrates a side view of the A, A,'a.re round pins, greferabl blade-holding pin; Fig. 5 illustrates the device in operation.

rec to' revo ve on forming a cage, which is tube G, which passes through the plates B, B,

and also asses throughthe handle frame J. A knurled nut H, is made fast (permanently to the outwardly projectin en of the tube 0, and is engaged with the frame J by means of recesses I, which fit over a pin It, which projects from the frame J. There are two of these notches or recesses I, directly opposite each other. Spaces M, M, are left between the plates B, B, and the frame J, so that by springing the .frame J, slightly together,

these s aces are closed, and the nut H, re-

leased rom the pin R. Thus it can be .turned one half revolution to the other notch presenting the other side of the razor blade towards the leather strop. The handle rod K turns freely in the frame J.

.L is a handle fast on the handle rod K. In Fig. 4 I show the blade holding pin F.

than half its length. Where it passes over the blade G, and through-two or more looplike ortions D, D of the tube C, it has a smal knurled ball". secured to the head for convenience in pushing it in or out, as the blades are fastened orreleased. The loops D, D, pass through holes made in the blades. In blades of the so-called Gillette safet razors, the holes made in the blades througfi which the clampingbgbogs pass, ma be used and O, are ins which hold the tube C, and handle rod respectively in place in the I frame J.

The action of this device is shown in Fig. 5.

fThe razor blade G is shown in the position of being drawn along the strop towards the left,

are smal washers the handle rod at K being held in the hand offthe operator to effect this movement. It will be noticed that when the motion t0 theleft is stopped, and a movement to the right begins, the first action is a rolling movement of the tube 0 on the strop leather P, which.- immediately lifts the right hand edge of the razor blade G away from the strop, and brings in contact the lefthand edge of the blade before any forward motion is given to the cage, A, A, B, B, thus rendering it impossible'under any circumstances to cut the strop leather with the blade, no matter how care.- lessly the operator may work the handle.-- The device is absolutey automatic. simply necessary to work the handle back and forth, drawing the cage the length oftho strop leather and back again as rapidly as desired. v

The function of the cage is merely to steady and guide the blade as it is drawn 7 along the strop leather. It may be omitted and the sharpening action still be performed satisfactorily. The cage rods A, A, also prevent the leather from being marred or roughened by the loops D, vD, when the blade is turned over by the thumb nut H, so that they are turnedtowards the leather.

The device is extremely simple and has'a very perfect action which is accomplished without any'rollers, cog wheels, springs, or any 'destructible devices, and it IS exceed ingly neat in appearance, and it sharpens the blades so that they-are better, if anything, than when they are new. It is a well known fact that these thin blades will only give two orthree satisfactory shaves without sharpemng. Owing to the fact that the blades are held along their central line with equal rojection J laterally beyond the rock-shaft at either side, .9 the edges of the blade are alternately pre sented to the strop leather at a determined and correct angle, which cannot vary; thus very true edges are imparted to the blade. The amount of pressure with which the ed es of the blade are brought in contact with t e strop dependsu on the len th of the lever or a frame J. This has been celculated by prac-- tice and gives the best results in about the proportions shown in the drawings. It will be obvious to those who are familiar with such matters that modifications may be made in the details of construction of the said frame with the rock shaft and to disconnale nect it therefrom and means to clamp a razor blade upon the rock shaft.

. 2. The combinationof a cage embodying side lates and cross pins, a rock shaft jourd in the side lates, a handle frame sup orted onthe roc shaft, means on the hane frame adapted to engage co-acting and o positely locating devices on the rock shaft, whereby the said frame and shaft may be connected with and disengaged from each other in directly reversed positions and means to clamp a razor blade upon the rock shaft.

3. In a device of the class' stated, a rocking shaft having loops on one of its sides which are adapted to pass through perforations in a two-edged razor blade, means adapted to pass through the loops and clamp the blade to the shaft and means to rock the shaft.

4. In a device of the class stated, a hollow rocking shaft rovided with laterally projecting partsa apted to pass through perforations m a two-edged razor blade, a holding pin adapted to enter the shaft and pass through said projecting parts above the blade and clamp it to the shaft, and means to rock the shaft.

5. In a device of the class stated, a hollow rocking shaft having parts removed for the reception ofa two-edged razor blade, a pin adapted to enter the end of the shaft, pass above the blade and engage with other parts of the shaft, thus clampmg the blade thereto.

6. The combination of a cage embodying side (plates and cross pins, a rock shaft journale in the side plates, the cross' pins and rock shaft being in the same plane, a handle frame supported on the rock shaft, means to connect said frame with the rock shaftand disconnect it therefrom andmeans to clamp a razor blade on the rock shaft. I

7. The combination of a cage embodying side (plates and cross pins, a rock shaft j ourin the sideplates, a handle frame supnale ported on the rock shaft, means to connect said frame with the rock shaft and disconnect it therefrom, loop-like devices upon the rock shaft and a removable clampln pin adapted to assthrough said loops and 0 amp a razor bla e to the rock shaft.

8. In a device of the class stated, a rocking shaft, means to j'clam a two-edged razor blade centrally on sai shaft and a handle frame or support extending below the shaft adapted to rock the shaft and blade when pressed in opposite directions so :as to alternately present the opposite edges of the blade to the strop. r

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
