RAZOR-HONING MACHINE.

Specification of Letters Patent.

Application filed February 8, 1911.

Patented June 18, 1912.

Serial No. 607,284.

To all whom it may concern Be it known that I, JOHN KAYETAN, a citizen of the United States, and resident of Cold Spring, in the county of Putnam and State of New York, have invented cert-ain new and useful Improvements in Razor- Honing Machines, of which the following is a specification.

This invention relates to the sharpening of razors, and its object is to provide a means for holding a razor against a revolving honing stone or stropping roller, the means being in a variety of ways adapted for varying shapes and sizes of razors, in a manner that will make it possible to handle many razors in a short time.

The means are set forth in these specifications and the accompanying drawings, in which like letters and numbers refer to like parts throughout the several views.

Figure l is a side elevation of the machine. Fig. 2 is a front view of razor clamping devices detached from the machine. Fig. 3 is a plan of the inner parts of the lower clamping arm. Fig. 4 is a transverse section of the upper clamping arm. Fig. 5 is a plan of the inner parts of the upper clamping arm. Fig. 6 is an elevation of parts shown in cross-section in Fig. 4:. Fig. 7 is a front elevation of the razor blade auxiliary adjuster. Fig. 8 is a cross-section of the adjuster support. Fig. 9, Sheet 2, is a plan of the machine. Fig. 10 is a rear elevation of the machine.

Figs. 1 and 9 show the machine to be mounted upon a base I) that is recessed on its surface, as at 72, to receive a sliding block 73. Upon this block is secured a post p p and standards 8 8 The block is movable within the recess by means of the screw it which screws through the broadened base of the post, and is held from lateral movement'in the bearing is. The screw is turnable by the crank j.

About midway of the base are standards 0 0" which support the shaft 7, and upon the shaft is a drlving pulley 74, and an abrading or honing roller 1". Beneath the roller, inclosing the under part of the roller, is a box 6 for holding 'oil, water or other lubricant for use on the roller. The box has flanges 36, Figs. 1, 9, 10, on its bottom that extend within grooves in the standards 9. A rod 31, Figs; 1, 9, fast to the front of the box has an end support 32 fast upon the base Z). A nut 34 is on the rod next the box, and a spring 33 upon the rod is compressible by means of the nut. Within the box a stone 30 is held by a screw 35 in a bracket 35 the stone being designed to be kept in contact with the roller to keep back a superfluous quantity of lubricant, and at the same time help to maintain the regularity of the surface of the roller. The pressure of the stone against the roller is controllable by means of the nut and the spring.

. A description of the standard .9 and the parts supported by it will apply also to the standard 8 as one is a duplicate of the other, except that one is right handed and the other left handed. Upon the standard 8, which is fast on the block 73, is a sliding arm a, Figs. 1, 9, and 10, and in detail in Figs. 2, 3. Mounted'upon the arm is a block afi'see also Figs. 5, 6, hinged thereto by means of the lug 66' on the arm, the recess 69 in the block, and the pint-1e 67, Fig. 1. The block and arm are held closed by the catch 22, pivoted on the arm, and the pin 23 on the block. A handle 24 is provided on the catch. These two parts constitute a vise or clamp for holding the razor, and they are made vertically adjustable upon the standards by means of a lug 58 on the arm, which passes over a screw 60 that is fast on the base of the standard. A spring 61 rests upon the lug, and a nut 62 on the upper end of the screw is for adjusting the tension of the spring which always has a downward thrust upon the lug. A nut 59 under the lug is to regulate the amount of the downward pressure when the razor is in contact with the honing roller.

The means for holding the razor are in the ends of the clamping arms. A base piece or anvil 1 has a semi-circular seating in the arm a, and its flat surface may be held level or be turned to an angular position as shown in Fig. 1. An arm 2, Figs. 1, 3 and 9, is fast to the anvil and has a ver tical swing upon the screw-stud 3. A lever 5 is pivoted to the arm a at 6, and the long end of the lever engages with the arm 2 by passing through the lug 4 which is a part of the arm 2. The short end 7 of the lever 5 is'acted upon by a screw 8 in the projection 12 on the arm a, and a spring 11 keeps this end of the lever against the screw. By means of the screw the posit-ion of the face of the anvil is regulated.

Immediately above the anvil 1 is a like anvil i reversed in its position. Figs. 4, 5, 6, show the details relating to this upper anvil. Fig. 4 shows a recess 29 in the block a fitted with a round guide 15, concaved in its outer end to fit the convex surface of the part 2', which has a lug 13 upon its conveX side extending into a slot in the guide. The lug is slotted and through the slot is a pin 14. Thus the anvil is turnable in its seat in the guide, and is manipulated by a lever 18 fast to one end and extending up the side of the block a A guard 19 keeps the lever in place, and limits the downward movement of the guide and anvil. The razor to be honed is held between the anvils, and to facilitaterthe holding the anvil is normally thrust downward by the spring 16, Fig. 4. For compressing the upper anvil against the lower a screw 17 is provided. At 71, Fig. 1, the position of the razor shank between the anvils is shown.

In front of the anvil 1 is an adjustable jaw 26, Figsal, 3, 9. It has a plain front face, while its back is tapered from its center to each end, and it is supported on a central pivot 27, Figs. 1 and 3. The jaw has a solid backing at its center, and is movable on its pivot by means of the screw 25, and a spring 28, Figs. 3 and 9, holds it normally against the screw. The object of this jaw is made plain in Fig. 9, in which the shank of the razor, 71 is shown to be secured. Uusually the shank of a razor is not parallel with the edge of the blade, so that to adjust the razor blade parallel with the roller 1", adjustment has to be provided in the shank clamping means. Fig. 9 explains clearly the object of the adjustable jaw. To hold the razor'shank against the jaw solidly, in the arm a is a sliding clamp 9, shown particularly in Fig. 3. The clamp is swiveled at 68 to a screw 10, which extends to the rear of the arm a.

In Fig. 9 it will be seen how this clamp is pushed forward to secure the razor shank against the adjustable jaw. The anvils are recessed, as at 20, Fig. 4, to admit of the advance of the clamp 9. This is made necessary by the varying widths of razor shanks. It is thus shown how there are several points of adjustment to bring the razor to a proper position on the honing stone, namely, the adjustable anvils the movable clamp 9, and the adjustable jaw 26. The object of making all these parts movable by means of the screw 72. is, that they may be 'moved back, away from the roller 1" during the setting and all but the finer adjustments of the razor. With a like object the razor holding arms are adapted to be raised and lowered, by meansshown in Figs. 1, 9 and 10, and particularly in Fig. 10. Crank-levers 56 lever 56. manipulatmg these several parts. The crank,

56 are pivoted at 57 57 to the standards.

.9, .9 with their short arms 56 56 under the edges of the arms a, (f. In the post p is a shaft 53, and on the inner end of the shaft is a cross-arm 52. The upper end of the cross-arm at 63 is connected by the bar 54 with the long arm of the lever 56 at the point 64. The lower end of the cross-arm at 65 is connected at 64 with the long arm of the A crank a on the shaft is for in the position shown causes the lifting of the arms a a as shown. Turning the crank the way of the arrow allows the springs 61, 61 to force the arms a, a downward to contact of the lugs 58, 58 with the nuts 59, 59 and these nuts are manipulated to adjust the contact of the razor with the honing roller.

In honing a razor it is operated upon on both sides, which is the object of duplicating the holding means described at the ends of the honing roller, and the practice should be to give each side equal treatment, for which purpose an indicating bell is provided, as in Fig. 10. A bell is held to the standard 0. A lever 77 pivoted to the standard is operated by a pin 76 in the shaft f. A spring 79 holds the lever 77 normally against the stop 78. A clapper 80 strikes the bell at each revolution of the shaft By counting the bell strokes, the same number of revolutions of the honing roller may be given upon each side of the razor, the razor being moved to and from the roller by means of the crank 2.

Upon the post p is a slide at with a grooved cross-arm m Figs. 1 and 9. An arm 7 slides in the groove of the arm m and is slotted to pass over the upper end 19 of the post p, and also the holding screw 50.

A set-screw 51 secures the slide in position, and the nut 49 holds the arm n in position. The forward end of the arm 'n carries a spindlet that can be raised and lowered in its socket, and is held by the screw 44. To prevent turning sidewise the end of the screw 44 is seated within grooves 45', Figs. 1 and 7, in the spindle. As the spindle is reversible a groove is provided on opposite sides of the spindle. Abracket 0 p on. the end of the arm a affords a guide for the screw 46 which is fast in the spindle t. A spring between the bracket arm 37 and the end of the spindle and a nut 48 above the bracket arm makes the spindle vertically adjustable by means of the nut when the screw 44 is loose.

The lower end of the spindle t is provided with a'sliding holder for a fingerpiece w. A front view of these. several parts is given in Fig. 7, a side view in Fig.1. A casing u is fast to the spindle and has a drooping flange 70. WVithin the casing u is another casing '12, within which the finger piece is pivoted at 43. The casing o is moved back and forth in the casing to by the screw 38, which screws into the spindle t. The bar y connects the casing '0 with the arm (Z which slides in the spindle t. A screw 39 is pivoted to the finger piece to and extends upward through a bearing in the end of the arm (Z. A spring 40 on the screw bears against a collar on the screw, forcing the screw downward, so that the raising and lowering of the finger piece is controlled by the nut 41. This device is midway between the razor clamping arms, as shown in Figs. 9 and 10. When the razor is in place on the honing roller this auxiliary blade adjustment is lowered and the flange 70 is brought against the back of the blade, as in Fig. 1, and what is called the finger piece can be lowered upon any part of the width of the blade between the back and edge, and the pressure that will be exerted upon the blade is 0011- trollable by the nut 41, the position. of the flange 70 being controlled by the screw 38. The upper end of the post p is narrowed as at 19 Fig. 8, to fit the slot in the arm n to avoid undue width and heaviness that would be required in the arm n if it were fitted over the full width of the post p.

The various operations required to set and adjust a razor for sharpening having parts, it is not necessary to repeat them.

For stropping a razor a leather or other bufiing roller may be substituted for the honing roller, and for this use the lubricant box 6 can be dispensed with. For some kinds of work the stone 30 will not be required in the box, when of course the sliding features of the box and the spring adjustment would be discarded. It will not be essential in all cases that the indicating bell be used. In some uses the auxiliary adjusting devices will not be required, so that it is plain that I do not wish to be confined to the constructions I have shown, nor to the exact forms shown, so long as I do not depart from the principles of my invention.
