HONING MACHINE. APPLICATION FILED JULY27, 1905.
"No. answer.
To all wlumt it "may concern.-
Be it known that i, Cnamrns F. BOLDT, a
I citizen of the United States, residing at Dedo declare the following troit, in the county of Wayne, State of Michigan, have invented certain new and usefiil Improvements in Horling-iviachines; and I to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the, same, reference being had to the accompany ing drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to a machine for honing razors; and. it consists in the construction and arrangement of parts hereinafter fully set forth, and-pointed out particularly in the claims.
The object of the invention is to provide simple -and efficient means for honing the blade of a razor by the rotation of cylindrical stones and to provide for steadyingthe razor when being operated upon and directing it properly between the stones.
The above object is attained. by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a machine embodying my invention, showing a razorblade in. position for honing. Fig. 2 is an end elevation of Fig. 1, the tang of the blade being in section. Fig. 3 is a plan view of the machine. Fig. 4 is an enlarged transverse section as on line 4 of Fig. 1.. Fig. 5 is a pers ective view of the slotted guide-plate in whic the blade is held while being honed.
Referring to the characters of reference, 1. indicates a suitable frame in which are journaled the shafts 2 and 8, respectively, upon which thecylindrical honing-stones i and 5 are mounted. The shaft '2, as shown by dotted line 6 in Fig. 1, passes through horizontally-slotted openings in the frame, thereby permitting said shaft and the cylindrical stone 5 to be moved toward and from the are alwa s maintained in coi'itie'uous workin o b relation.
Upon the projecting ends of the shafts 2 and 3 are the grooved wheels 8 and 9, re spectively, and mounted. upon a short our- Specification of Letters Patent. 7 Application filed ly 71 905- serial NO- 271,4;77.

rial-bolt 10, which is adapted to adjust vertically in a slot 11, (shown by dotted lines in Fi 2,) is a grooved idle wheel 12. Journa ed at 13 at the end of the frame is a rooved driving-wheel 14, having a projecting handle 15, through. the medium of which said wheel may be rotated. Passing around the driving-wheel, over the idle wheel 1.2, and under and over the grooved wheels 8 and 9, respectively, is a driving-belt 16, whereby through the rotation of the driving-wheel the shafts 2 and 3 and the cylindrical grindingstones 4 and 5 thereon are caused to revolve in unison in opposite directions. By an adjustment of the idle wheel 12 a proper tension upon. the belt may be made.
It is necessary that the blade 17 of the razor be presented squarely between the grinding-stones and held perfectly in position during the operation of honing to obviate grinding more upon one side than the other. This result is accomplished by means of the supporting-plate 18, having a longitudinal slot 19 therein, through which the blade" of the razor is adapted to extend. At the ends of said plate are the hangers 20, having the angular end portions 21, provided with squared apertures 22, adapted to receive the posts 23, projecting vertically from the ends of the frame. Surrounding said osts arid confined between the angular en portions of the hangers and the top of the frame are the coiled compression-springs 24, whereby the plate 18 is normally held suspended, but permitting said plate to be depressed, so as stones. 1
A small grooved wheel 25 is mounted on the 'hub of the driving-wheel to enable the machine to be driven by a motor, if desired.
The driving-wheel being turned to the right, the stones will be rotated in the direc tion indicated by the arrows, so that the ac tion upon the blade is upward, away from the edge, enabling the razor to be honed as desired by applying sufficient downward pressure to the blade to hold it in contact with the stones. Oil, soapy water, or other suitable lubricant may be placed upon the stones during the operation of boiling.
, Instead of using the belt 16 and the grooved wheels 8- and 9 the shafts carrying the cylindrical stones may be driven by a train of gearing without departing from the spirit of my invention.
Having thus fully set forth-my invention, what I claim as new, and desire to secure by Letters Patent, 'is
1. Ina razor-honing maohinathe combination of the cylindrical stones, rotatively mounted and held .yieldingly in peripheral contact, a supporting-plate for the razorblade to direct the blade between said stones, and springs for supporting said plate to allow of a' Vertical movement thereof.
2. In a razor-honing machine, thecombination of ,ithe shafts, the cylindrical stones thereon, springs connecting the ends of said shafts, a driving-Wheel, pulleys'upon said 1 shafts adapted to carry a belt from the driving-wheel, an idle Wheel engaging said belt, and means for directing the blade to the 'grindingstones and permittin'giof a vertical reciprocation thereof.
'3. In a razor-honing machine, the combi- CHARLES F. BOLDT. Witnesses E. S. VVHEELER, I. G. HOWLETT.
