DEVICE FOR HONING AND STROPPING RAZORS.

SPECIFICATION forming part of Letters Patent No. 759,626, dated May 10, 1904.

Application filed January 27,1904. Serial No. 190,776. (No model.)

. simple and effective mechanism for producing the required oval or elliptical movement of a razor or other blade over a sharpening-sur face.

A further object of the invention is to provide mechanismof novel construction so arranged with relation to a yieldingly-supported hone as to insure the movement of the blade being sharpened over the entire surface of the hone, thereby avoiding undue wear upon the latter and the consequent formation of ridges or uneven places thereon.

A further object of the invention is to provide effective means for securing a uniform frictional contact between the blade and bone, thus avoiding uneven wear upon different portions of the sharpening-surface and equally distributing the weight or hearing contact throughout the edge of the blade.

In addition to the general features above outlined the invention consists of the novel devices hereinafter described for guiding and cushioning the moving parts of the mechanism and for preventing the accidental displacement of the operating handle or lever while the-razor or other implement is attached thereto.

The construction of the device will now be specifically described in connection with the accompanying drawings, in which- Figure 1 is a top plan view ofthe invention, showing a razor attached thereto in position for honing. Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is a detail section on the line 3 3 of Fig. 1. Fig. 4 is a section on the line 4 4 of Fig. 1. Fig.

5 is a top plan view of the vibrating plate constituting an element of the mechanism dctached from the disk to which it is pivoted.

Fig. 6 is a transverse vertical section of said plate on the line 6 6 of Fig. 5. Fig. 7 is a detail perspective view illustrating the means for detachably securing the inner end of the operating-handle to the movable rod of the device. Fig. 8 is a perspective View of one of the supporting-holders of the hone. Fig. 9 is a perspective view of one of the bracketbearings of the hone-holders. Fig. 10 is a plan view of a modified embodiment of the invention adapted for the sharpening of safetyrazors, and Fig. 11 is a section on the line 11 11 of Fig. 10.

The reference-numeral 1 designates a base serving as a support for the hone and operating mechanism and preferably provided with rubber feet or pegs 2. Obviously, however, a table or any other suitable support might be substituted for the base-board shown.

3 designates a disk pivotall y supported upon the base 1 by means of a bolt 1', extending centrally through the disk and through the chase, the under surface of-thc latter being countersunk to accommodate a nut 5, for securing the bolt 4. A flanged wear-plate 6 is interposed between the base and the disk 3, as best shown in Figs. 2 and 3.

The disk 3 is formed with a vertical opening7 in rear of the center, through which ox tends a post 8, having a transversely-bored head 9 to receive the rear end of a iftitll ld, a coilespring 11 encircling said rod between the head 9-and a cross-pin 12, extending through the rod. To the opposite sides of the. lower end of the post 8 are secured the inner ends of coil-springs 13, said springs'being located in a recess 14:, formed in the upper surface of the base and having their outer ends secured to the adjacent end walls of the recess 14:, Fig. 3. The function of these springs is to retract and equalize the rotary movement of the post 8.

15 designates a plate resting on the disk 3 and pivotally secured thereto by a pivot screw 16. This plate is formed with stop-lugs 15 and an elongated slot 17, through which latter extends the upper end of the pivot-bolt of the disk 3, thus affording said plate a limited lateral vibrating movement without moving the disk.

Pivotally secured upon the plate 15 by a screw-pivot 18 is an arm or link 19, having eccentrically pivoted upon its upper surface a small disk 20, from which projects eccentrically a pin 21, the latter extending through the rod 10.

22 designates the operating lever or handle of the device, having a bend or offset 23 adjacent to its outer end to accommodate the handle of the razor, as shown in Fig. 1. This handle 22 is detachably secured to the forward end of the rod by means of a couplingsleeve 24:, secured by a set-screw 25 to the rear end of the handle and formed near its rear end with an L-shaped slot cooperating with a cross-pin 26, extending through the rod 10 to form a bayonet-joint.

1 A weight 27, having an eye extension 28, is

secured upon the sleeve 24: by a set-screw 28.

The handle 22 is provided near its outer end with a spring-clip 29, which firmly clamps the "razor-blade in position against the handle, as illustrated in Fig. 1.

The hone or sharpening device is of the rectangular shape shown and is yieldingly supported in front of the disk 3 by means best shown in Figs. 8 and 9. The hone is supported in an inclined position with relation to the disk 3, its supporting means comprising end clips or holders'30, embracing the ends of the hone, and each having an outwardly-projecting pivotlug 31, fitting a bearing-slot 32, formed in the vertical member of an adjustable anglebracket 33,said brackets being secured at opposite sides of the base and bored to receive adjusting-screws 3 1 to facilitate the vertical adjustment of the hone-pivots. This manner of suspending the hone permits it to move freely on its pivots, withthe result that the edge of the blade being honed is always in proper contact with the surface of the hone. The stone may also be removed or adjusted without removing the bearings.

The operation of the mechanism constructed as thus described will be readily understood.

After the razor or other blade is placed in position upon the handle the latter, together with the rod 10, is given a longitudinal thrust against the tension of the coil-spring 11. The connection of the rod 10 with the small disk 20 bymeans of the pin 21 revolves said disk 20 as the rod and handle are moved laterally. This lateral movement of the rod is permitted by the pivotal movement of the arm or link 19 and plate 15. The movement of the arm or link 19 upon the plate 15 is limited by the lugs 15, and when said arm strikes one or the otherof said lugs the lateral strain is imparted to the plate 15 and through the intermediacy of'said plate to the disk 3, causing the latter to partly turn on its pivot. Thus the move- 1 ment of the operating-handle, aided by the An important result of the construction and relative arrangement of the mechanism is that all portions-of the hone-surface are brought into contact with the edge of the blade during the manipulation of the handle or operatinglever, and it will be apparent that the blade may be readily reversed without detaching the operating-handle from the rod.

A distinguishing characteristic of the invention is that it avoids the employment of gearing, belts, and crank-handles, the operation of the handle carrying the blade simulating the ordinary hand manipulation of a razor and accomplishing the same result, but in much less time, much more accurately, and with appreciably less labor.

It will be apparent that when the razor is in position upon the handle 22 the back and edge of the razor will bear on the stone at the same time and the handle not come in contact with the surface of the stone at any point. It Will also be apparent that the handle 22 cannot be accidentally disconnected from the rod, as the blade will prevent the turning of the handle to the position required for the separation of the handle and rod, and the blade must first be removed before they can be separated.

In the modification shown in Figs. 10 and 11 the handle 22 is straight and the springclip 29 to receive the razor-blade is located near the rear end of the handle, these variations in structure being necessary to adapt the device for supporting and sharpening the short blade of the so-called safety-razor.

, I would have it understood that the invention includes, in addition to the construction illustrated in the drawings, all such modifications and changes in-the details as may fall within the scope of the invention as defined by the claims.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
