to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. i

This invention relates to new and useful improvements in. stropping devices for razor and other blades; and it consists in the construction and srraiigement of parts hereinafter fully set forth, and pointed out pen ticularly in the claims.

The objects of the invention to provide simple and elliciont means for turning the blade of the razor {it the beginning oi a stroke so that the edge cl" he blade will be automnticnlly brought into contact with the stroppingsurface and will stand in a direction opposite to that in which the blade is moved.

A l'urtl'icr set is to provide means for au 'tomatically returning the blade-holder to en rest.

A further object is to provide means for supporting the handle oi the razor when the blade is in the holder in the operation of stropping.

The above objects are attained by the structure illustrated in the accompanying drawings, in whicl Figure 1 is an elevation showing my im proved stropping devic with a razor in po sition therein. Fig. 2 is a transverse section as on line 2 2 of Fig. 1.. fl is a transverse section as on line 3 ct l i 1, showin g by dotted lines the movement or e bladeholder. 1 is view similar to Fig. 3, showing by solid lines the blade-holder swung to one side, so as to bring the edge of the blade into contact w th the surface of the strep. Fig. 5 is a transverse section on line 5 5 of Fig. 1. Fig. 6 is an enlarged vert cal section through one end of the blsdeholder, the friction-roller, the gem" ig, and other parts, through the medium of which the swinging oi the blade-holder is accomplished.

Fig. 7 is an enlarged viewyin longitudinal section, through the blade-holder, showing the slidable spring clamping-arm which is adopted to support the handle of the razor.

Fig. 8 is a fragmentary view in perspective of the spring-jaws at the end of said arm.

Referring to the characters of reference, 1 designates a ei-shaped frame between the ends of which is journaled the friction-roller 2, which is made fast to its journal-pins 3. Fixed to and extendin nearly the entire length of the frame 1 is a. blade-holder 4, comprising diverging spring sides which are adapted to clamp between them the' blade 5 of the razor, which is inserted endwise be 'tween said spring sides. Fixed upon one of the journal-pins 3 is a gear-wheel 6, which meshes with a like wheel 7, fixed to a short shaft 8, whose ends are journaled in the opposed plates Qsnd 1.0, which are held together by the binding screws or bolts 1 1. The shaft 8 projects through the plate 10 and receives upon the end thereof the arm 12. This arm is provided in its upper end with a slot 13 and with a recess extending downwardly from said slotin which is seated the coiled sprin 14. Fixed to and projecting from the frame 1 is apin 15, whose outer end lies in the slot 13 in the arm 12.

In the operation of this device the frictionroller 2 is pressed upon the leatherstrop 16, and by means of the handle 17, which projects from end is secured in the plate 10, the device is moved longitudinally of the strep. At the inception of the movement in either direction the roller 2, because of its contact with the strep, willturn slightly, thereby turning the gears 6 and 7 and swinging the ern'i 12. The movement of said arm is imparted to the frame 1 and the blade-holder through the medium of the pin 15, which lies in the slot of saidv arm, whereby as the device is moved in one direction along the surface of the strep the frame and blade-holder, be cause of the interposed gearing, are swung in the opposite direction, csusing the blade to move into contact with the surface of the' strep, as shown in Fig. 4. At the termination of the stroke in one direction and the in ception of the return strokev the frictionroller 2 is rotated slightly in the opposite direction, thereby swinging the blade-holder to the opposite side, as shown by dotted lines in Fig. 8. Because of theprcsence of the coiled spring 14 the blade-holder is returned to an upright position whenever the pressure upon the strop is relieved, thereby preventing a possible cutting of the strop, as the blade is always raised from contact with the surface thereof whenever the device is arrested in the operation of stropping.

Lying within the blade-holder is a s ringarm 18, which is made to slide longitu inally of the holder and is confined in place by the rivet 19, (see Fig. 7,) which passes throu h a slot 20 in the bottom of the holder. At t e outer end of said arm are the opposed springjaws 21, which are adapted to embrace the handle 22 of the razor," The purposeof said spring-arm, with its clamping-1 ayvs, is to support the handle of the .razor when strop ing. in most razors the handle becomes -oose upon the rivet which secures it to the tang of the blade, and if the handle were not supported it would fly around in the operation of strbpfping to such an extent as to materially skill/91.

ere with the operation, Within the center of the spring-arm is a ii-shape point 23, which when the arm is drawn outwardly engages the tang of the blade, so as to throw the end of the arm downwardly and present the jaws 21 in proper position to grasp the han- .ing

' ab e spring-arm in the blade-holder, said arm dle, as shown in Fig. '1. The adjustahility of the spring-arm enables it to be drawn outwardly such distance as to accommodate any length of blade and handle, and when not in use may be shoved inwardly out of the way, as shown in Fig. 7.

Having thus fully set forth my invention, what I claim as new, and. desire to secure by Letters Patent, is

1. in a blade'stropping device, the combi- 3. In a blade-stropping device, the com-' bination with the movable blade-holder, of a friction-roller, a gear-wheel thereon, a second gear-wheel meslnng therewith, a shaft upon which said second gear-wheel is fixed,'a movable arm fixed to the end of said shaft, said arm having a slot therein and a socket extending from said slot, a coiled spring seated in said socket, and a pin u on the bladeholder lying in said slot an engaging said pin.

4. In a stropping device, the combination of the blade-holder having a longitudinal slot in the bottom thereof, a friction-roller, means connected with said roller-for swingthe blade-holder from side to side, a slidhaving a rivet enga 'ing in the slot in the bottom of the blade wider and having jaws adapted to clamp the handle of the razor.

, In testimony whereof- I sign this specification in the presence oftwo witnesses.
