Application filed January 5, 1906- Rencwed-Februa'ry 28. 1907. Serlal No. 359.743.

To all whom it may concern:

Be it known that I, ELMER CLIFTON SHA- VER, a citizen of the United States, residing at N ew York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shopping- Machines; and I do hereby declare the foltion of the invention, such as will enable to make and use the same.

My invention relates to stropping-machines; and its object is to providea light and simple device of this character which can be quickly placed upon a strop and which is particularly adapted for stropping razorthough, if preferred, the machine can be as safety-razors.

Theinvention consists of a carriage having a blade-holder extending from side to side. thereof and adapted to swing from side to side, said holder being actuated by a gear which engages a rack connected to a handle to which the carriage is pivotally connected. The-holder is so mounted and constructed ment therewith and held thereby, and by pulling the carriage back and forth by means of the handle the holder will direct the blade downward upon the strop, so that the same will be drawn. thcreover with the carriage and without injuring the strop.

The invention also consists of so disposing be directed longitudinally thereon without The invention also consists of'certain other tion of parts which will be hereinafter more In the accompanying drawings I have shown the preferred form of my invention.

In said drawings, Figure'l is a perspective view of my improved stropping machine, the strop being shown by dotted lines and a razor also being indicated by dotted lines in positionupon the holder. Fig. 2 is a section through the machine and strop and showing chine is traveling in the direction of the arrow the blade (if the razor also being shown Fig. 2, but showing the positions of the parts when the device is moving in a direction opposite'tothat indicated by Fig. 2, the direction of movement being shown by the arrow.

' Referring to the figures by numerals of reference, 1 is a handle having a cross-strip 2 secured to one end, and disposed at one-end of this strip is an ear 3, while at its other end is an arm 4, which terminates in an open frame 5, the upper ortion of which is toothed to form a rac 6.- Pivoted to the ear 3 and to the. lower portion of the arm 4 are arms 7, which extend downward from side plates 8. These plates and arms constitute the sides of the carriage of the machine, and the two plates 8 are connected by rods 9, on which are disposedv sleeves 10,- which constitute 'rollers.' Connecting the central portions of the plates 8 at their upper edges is a rod 11, to which is permanently connected a clip 12, formed by bendinga' strip of sheet metal upon itself into substantially a U shape, and the sides of this clip taper toward each other, so as to firmly clamp the blade 13 of a razor and hold it against displacement. One end of the'rod 11 extends into the frame 5 and has a gear 1 1 fastened to it and which meshes with the rack 6. It. will be noted that the upper edges of the side plates 8 are recessed at opposite sides of the rod 11, and this is for the purpose hereinafter more fully set forth.

Inusing the machine hereindescribed a be noticed that the handle :1 hangs directly under the center of the strop, and therefore ward the carriage is moved evenly over the surface of the strop and. will not twist the same. When the handle is drawn toward the operator, as shown in 2,'the frame 5 when the same is pulled backward and for- ICC will-be swung away from the operator and will cause the gear'14 to rotate so asto swing the blade upon the stro as shown in Fig. 2.?

The carria 'e will thereforebe drawnin the direction 0 the arrow in said figure, and the edge of the razor Wll'l be carried over the surface of the strop. -When it ,'.lS desired to move the carriage in the opposite direction,- the handle 1 is swung away from the ofperatoi', and this causes a piomptreversalo the positions of the frame-5 gear 14, and holder l2, and all of the parts will assume the posinary form of razor, it will be understood that raised out of contact with the strop, or the holder from being lifted: "The side plates 1 1, when the blade is turned from side to side.

tion shown in Fig. 3 during the movement of the carriage in the direction of the arrow said figure.

While I have shown and described this machine for use in connection 'With the ordi- 1 it can also be utilized for stropping the blades of safety-razors. .I attach considerable importance to the fact that the machine can be used for stropping both forms of blades.

Another important feature of this device is the fact that the holder 12 can-be uickly reason that the rollers travel upon the strop and there is nothing to prevent the are recessed at their upper edges, as shown and described, so as to accommodate the shank of a razor-blade, suchas shown in Fig.

This is particularly desirable should the strop be loose and necessitate the blade swinging below the level ordinarily required in order to come in contact with the strop.

. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isa In a stropping-machine, the combination with a pair of plates and a depending arm .rigidwith each plate; of a pair of rollers be tween said plates one at each end thereof, a

blade-holder rotatably mounted between said platesfa gear at one end of said holder and integral therewith, a cross-strip below said blade-holdenan ear at one end of said strip, an arm at the oppositeend 'of said strip, means to piVotally secure said strip to the depending arms, a frame integral with the upperend of said arm, said framehaving an opening therein, a rack at the upper edge--
