PATENT JOHN A. BUTLER, OF SOUTHINGTON, CONNECTICUT.

RAZOR-STROPPER.

SPECIFICATION forming part of Letters Patent No. 792,117, dated June 13, 1905.

Application filed May 4, 1904. Serial No. 206.324.

To all whom, it may concern: 7

Be it known that 1, JOHN A. BUTLER, a citizen of the United States, and a resident of Southington, in the county of Hartford and State of Connecticut, have invented a new and Improved Razor-Stropper, of which the following is a specification.

My invention relates to the class of devices employed for the purpose of holding a razor and for properly locating the same on a strop in the stropping operation; and the object of my invention is to provide a device of this class that shall properly turn the razor as it it drawn along the strop and that shall also give the required lateral movement to the blade with respect to the strop, the mechanism being so constructed that the operation of the parts shall be free and easy and requiring little exertion on the part of the operator. A form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a top or plan view of a device embodying my invention with the parts shown in normal position. Fig. 2 is a bottom View with the frame swung to one side. Fig. 3 is an edge or side view of the device. Fig. 4 is a view in vertical section through all of that part of the device excepting the handle. Fig. 5 is a view in crosswise-section through the bend in the frame supporting the pinion-shaft looking toward the blade-holder.

In the accompanying drawings the letter (t denotes a handle of proper shape to be readily grasped by the hand, and in this handle is secured a support upon which the frame is mounted. This support consists of a shank 7/ and an operating-arm 7), the shank being located on one side of a pivot and the arm 7) projecting on the opposite side of said pivot.

The frame is pivotally mounted on the support, having a swinging movement on the pivot c. This frame includes a pivot-plate (Z, a spindle-supporting bend cl, and a rack-supporting bend (Z and fingers or rests (Z The pivotplate (Z is constructed of suitable form to receive the pivot 0 and also afford a proper hearing on the support. The spindle-supporting bend Z is preferably of inverted-U shape when seen in edge view and is formed integral with the pivot-plate (Z, all the parts of the frame, in fact, being preferably integral and formed of a piece of sheet metal struck up to the desired shape. The rack-supporting bend (Z is also of U shape, as shown in Fig. 3, and extends across the frame preferably from side to side. The fingers or rests 6Z3 extend from the rack-supporting bend (Z lengthwise of the device as a whole, as shown in Figs. 1 and 2 of the drawings. A guide cl" also projects from the frame and may be formed integral therewith or separately secured thereto, as shown, this guide extending from the frame in a lengthwise direction and having laterallyextending arms (Z A spindle c is mounted in the spindle-supporting bend (Z, one end of the spindle being located in one of the arms of the bend and the other end extending through the opposite arm of the bend and supporting a pinion f. There is also secured to the spindle c or to the hub f of the pinion f a blade-holder g. In the form of the invention as shown herein the bladeholder is provided with a socket-piece which is passed over the hub f of the pinion f, closely embracing the same, so that the hub and the blade -holder shall have a rocking movement together. The blade-holder has a recess formed by the sides in which a blade It is clamped and frictionally held, so that it may be readily removed from the grasp of the side parts 9.

A rack z' is mounted in the rack-supporting bend (Z of the frame, this rack having free lengthwise movement in the slideway in the bend. The upper edge of the rack is toothed to engage the teeth on the pinion f. The 0perating-arm 1) extends into a recess a" in the rack 2', passing through a recess cl in the racksupporting bend (Z of the frame. A spring k is wrapped about the spindle c, the arms of the spring extending on opposite sides of the operating-arm Z) and tending normally to hold the frame in a position with said arm projecting through the crosswise center of the frame.

In the operation of the device the stropper is placed upon the strop, the fingers or rests d resting thereon and the guide (Z located against the edge of the strop. As the handle (Z is moved in one direction the contact of the fingers (1 with the strop causes the frame to be swung to one side on the pivot c. This swinging movement of the frame on its pivot causes the rack i, by reason of the engagement of the arm 7) with the recess in the rack, to be "moved lengthwise in its socket in the rack-supporting bend (Z This lengthwise movement of the rack imparts a rotary movement to the pinion f, and consequently to the blade-holder g. It will be noted that the lengthwise movement of the stropper on the strop will have begun before the rotation of the blade-holder has been caused to an extent to bring the blade in contact with the strop, and the swinging movement of the frame also locates the blade in a diagonal position with respect to the strop.

The location of the rack in the recess in the bend (Z enables the rack to have a free and easy movement without any danger of cramping or wedging, and the engagement of this loosely-mounted rack with the pinion and the construction of the parts is such that an extremely free movement is imparted to the blade-holder, so that there is practically no resistance whatever by reason of the movement of the rack and blade-holder to the movement of the device as a whole along the strop, such movement therefore being unobstructed and practically as free as is the movement of a razor along a strop, it being readily understood that in the proper stropping of a razor to attain the best results the movement of the hand to cause the blade to be passed along the strop must be free and unobstructed.

' By the construction of my improved stropin that the rack is loosely mounted to slide in the frame and is not secured thereto, as in prior devices.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A handle, a frame pivoted to the handle,

a blade-holder mounted in the pivoted frame, a pinion operatively connected with the bladeholder, a rack loosely mounted to slide in the frame in engagement with said pinion, and connections between the handle and said rack.

2. A handle, a frame pivoted to the handle, a blade-holder mounted in the pivoted frame, a pinion rigidly connected with the bladeholder, a rack loosely mounted to slide in the frame in engagement with said pinion, and an arm extending from the handle in engagement with said rack.

3. A handle, a frame pivoted to the handle and having rests, a blade holder rotatably mounted in the pivoted frame, a pinion rigidly connected with the blade-holder, a rack loosely mounted to slide in said frame in engagement with said pinion, and connections between the handle and rack to impart movement to the latter.

4. A handle, a frame pivoted to the handle, a bladeholder, a pinion operatively connected with the blade-holder, a rack mounted to slide in the frame and in engagement with said pinion, and connections between the handle and said rack.

55. In a razor-stropper, in combination, a handle, a frame pivotally mounted on the bandle and including a rack-supporting bend, a rack mounted in said bend, connections between the handle and rack for reciprocating the latter, a pinion mounted in the frame and in engagement With the rack, and a blade holder operatively connected with said pinion.

6. In a razor-stropper, in combination, a handle, aframe pivotally connected to the handle and including a spindle-supporting bend and a rack-supporting bend, a spindle mounted in the arms of the spindle-supporting bend, a pinion borne on said spindle, a rack mounted in a recess in the rack-supporting bend and in engagement with the pinion, an arm projecting from the handle in engagement with said rack, and a blade-holder operatively connected with said pinion.
