HONING AND STROPFI'NG DEVICE.

Application filed October 17, 1927. Serial No. 226,698.

This inventio-n relates to new and useful improvements 1n honing and stropping devices.

In common practice, razors are honed and stropped by having the two straps attached to some stationary object having a hook for engagement with an eyelet turnably mounted in a clip thatiirmly holds the two straps together at one end, while the free ends are held by t-he hand to keep them in a taut position while the razor is being sharpened but should the straps be too slack they may turn and by one st-roke the straps are cut which eventually necessitates the replacement of the straps by new ones.

It is one of the objects of the present invention to provide a honing and stropping device that will hold the straps in aA taut condition throughout the operation of sharpening a razor.

It is a further object of the invention to mount the straps in Vsuch a manner that they may be alternately turned and kept in the same taut condition by the actuation of a push rod.

Another object of the invention is to provide a honing and stropping device which does not necessitate the finding lof some convenient object to hang one end to, during the stropping of .a razor. v

With these and other objects inview, the invention consists'in cert-ain novel features, construction and combination of parts hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art to which the. invention pertains.

The invention will be clearly understood from the accompanying drawing, illustrating the invention in its preferred form, and the fol-lowing detailed description of the construction therein shown.

In the drawing e Figure 1 is a perspective view of my improved honing and stropping device.

Figure 2 is a vertical longitudinal sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a vertical transverse sectional view on the line 3 3 of Figure 2.

Figure 4 is a' horizontal sectional view taken on the line 4 4 of Figure 2.

Figure 5 is a detail perspective view of one of the T-shaped keys.

Referring more particularly to the drawing, the reference numeral 10 designates my improved honing. and stropping-device in its entirety which includes an elongated base 1l having a U-shape brackete12 mounted on the upper face thereof. The ears 13 and 14 of the bracket constitute bearings or supports for a turnably/mounted stropping and honing element 15 of aA construction now to be described. i

The stropping and honing element 15 consists of an elongatedl plate 16 abutting a T- shaped key 19 at opposite ends and a` bearing nut 17 which is turnablyA mounted in the ear 14 of the bracket and is fixed to the key by a removable pin 18. The opposite end of the plate 16 also abuts the inner end of a similar T-shaped key 19 which has its shank v extending through and fastened to a segmental gear 20 by a set screw 21. The gear 2O isy provided with a hub 22 which has its bearing on the ear 13 of the bracket in axial alignment with the bearing nut 17 `mounted in the opposite ear 1 4 thereof. e

Attached tothe plate 16 and the T-shape keys 1,9 are honing and stropping. straps 23 and 24 respectively, and which are removably applied for replacement when worn. In app-lying the above straps, plate 16 is removed from its bearings and the adjacent ends are attached to the keys 19 while in'an elongated condition by bolts 25. Interposed between the keys and the ends of thestraps are metal f washers 26 while bendable .plates y27 are placed between the ends of the plate 16 and the strap ends. The straps are then folded down and pulled taut softhat the metal plates 27 overlie the heads of the. bolts and retaining nuts to prevent wear between the bolt heads and nuts, and the straps. The opposite ends of the straps are identically fixed and any slack which might have originally existed has been arrested.

For the purpose of actuating the element 15 to alternately reverse the straps, I provide a sliding rack member 28, the teeth of whichy engage the teeth of the gear segment 20. A housing 29 is removably applied to the end of the base 11 and co-acts with the ear 13 for completely housing the gear segment and rack to exclude dust and dirt from the working parts. For guiding the rack member 28 in its lateral movements, I provide a iange or rib 29 which projects from the outer face of the ear 14 into a. groove 30 provided in the inner side face of the rack member. Motion is imparted to the rack member by themanual actuation of a push bar 31y extending from one of the sides of the base 11 and which has its inner end pivotally connected'to one end of a pivoted rock lever 32V disposed Within a recess 33 in the base.A The llower end of the rack element 28 is notched as at 34: for freely receiving the free end of the rock lever to cause the same to be moved in opposite directions. A leaf spring 85 is fixed to oneivall of the recess and has its free end abutting the side of the rock lever 32 to which the push bar 31 is connected; The spring normally holds the ack member 28 in a position at the limit of its movement in one direction so that the honing strap 23 is `normally on top, as this is the `first strap to be used When sharpening a straight blade razor. After the honing operation which is performed by holding the device in one hand of the operator with his thumb on the manipulating end of the push Y bar 31, the operator pushes upon the push bar causing the actuation of the. rock lever 32 against the action of the spring ivhich in turn moves the rack member 28 to the limit of its movement in an opposite direction, thus imparting a. half revolution to the stropper element through the actuation of the gear segment 20. The stropper strap is now face up and may be used to complete the razor sharpening operation. When finished, the operator releases the pressure upon the push rod 31, whereupon the spring 35 causes the parts to automatically return to normal position.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied Without in any Way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the Whole of my invention limited only by the appended claims.

lVhat is claimed as new is 1. In a razor sharpening device, a rotatable stropping element having different stropping surfaces on opposite sides thereof, spring means normally holding one of said stropping surfaces face up, and manually operable means for imparting a turning movement to said rotatable stropping elcment against the action of said springmeans to reverse the position of said stropping surfaces, said last means including a gear segment iixedly attached to` said stropping element, and slidable rack member co-acting therewith.

2. A razor sharpening device comprising a bracket, a stropping element turnably mounted in said bracket and h aving different sharpening surfaces on opposite sides thereof, 'a gear segment on one end of said stropping element, a slidably mounted rack member engaging said gea-r segment, a rock lever having one of its ends extending` into a notch in said rack member, and a push rod pivoted to the other end of said rock lever, substantially as and for the purpose specified.

A razor sharpening device comprisingl a bracket, a. stropping element turnably mounted in said bracket and having different sharpening surfaces on opposite sides thereof, a gear segment on one end of said stropping element., a slidably mounted rack member engaging said gear segment, a rock lever having one of its ends extending into a` notch in said rack member, and a. push rod pivoted to the other end of said rock lever, and a spring ac ting against said'rock lever to hold said rack member at the limit of its sliding movement in one direction.

In testimony whereof I have affixed my signature.
