Specification of Letters Patent.
Patented June 8, 191 .5.
Application filed uly 30, 1909. Serial No. 510,4;68.
To all whom it may concern Be it known that l, GEORGE BROWNING, a subject of the King of England, residing at Chicago, in the county of (look and State of Illinois, have invented certain new and usefulv Improvements vin Stropping-Machines, of which the following is a description.
My invention relates to devices for stroppin or sharpening a razor or other cutting bla e, and for this purpose is provided with improved stropping elements and with means or holding the blade to be sharpened in the mostadvantageous position for the convenient and accurate application of the sharpening mechanism.
The object of my invention is to provide a simple, convenient and efiective device oftbe kind described, and to this end consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.
In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts: Figure l, is a side elevation of my device. Fig. 2, is an end elevation of the same. Fig. 3, is an elevation of my device showing the end oppositethat shown in Fig.2. Fig. 4:, is a section taken substantially on line l4 of Fig. 1. Fig. '5, is a section of the blade holder of my device taken substantially on line 5-5 of Fig.4. Fig. 6, is an enlarged sectional detail, showing the base holder and coiiperating parts. Fig. 7, is a perspective detail of the blade holder. Fig. 8, is a perspective detail of a distance piece for adjusting the position of a blade: in the blade holder. Fig. 9, is a fragmentary view showing a portion of a blade holder with the distance piece shown in Fig. 8 in operative relation thereto.
In the preferred form shown in the draw ings a suitable frame is provided consisting of a pair of substantially vertical end members l and 2 rigidly connected near their lower and upper ends by the transverse members 3 and 9 respectively. in the form shown each end member is provided at its lower end with one or more parts 4 bent inward to a position substantially parallel to the member 3 and adapted to serve as feet or bearings for the frame. If desired a pad 5 of rubber or other suitable material may be provided, extending through a suitable opening in each part a or otherwise conventhe form shown, each member is provided iently secured in Position to serve as a cushion to prevent slipping or marring the surface upon which my device is resting. A pair of substantially parallel rollers or members 6 and 7 are rotatably mounted in suitable bearings upon the end members 1 and 2 each provided with a gear 8 rigidly secured thereto and arranged to cooperate to rotatively connect the members so that a rotation of one will produce a corresponding rotation of the other. The stropping or sharpening ele-, ments may be of any desired construction, and mounted upon or secured to the members 6 and 7 in any desired manner. In
with a pair of suitably formed plates 10-10 slightly spaced from each other and-arranged to extend longitudinally thereof. The central portion of each plate is formed to clamp upon the member with a part 11 projecting radially at each side, adapted to engage a suitable stropping or sharpening element between them. As shown a plurality of screws or bolts 12 are provided in the extended portions of the plates 10 adapted to draw I the plates together to clamp the stropp'ing elements in position upon the member.
The stropping orsharpening elements each preferably consists. of a substantially flat sheet or plate 14: of soft rubber or other suitable resilient'material rigidly clamped in a radial position between the extended portions 11 of the plates 10 with its periphery or outer edge projecting beyond the plates. A suitable covering er leather or other stropping material 15 is arranged to inclose the outer'edge of the sheet 14 and extends into the space between the sheet 14% and ate 10 to secure the same in position. 95
In he preferred construction the plates 10 are so formed that the stropping elements are arranged spirally upon the members and extend longitudinally thereof substantially the entire length of the members. 100
that a blade 18 extending into the space be- 105 tween the members will have its opposite sides engaged alternately. In the preferred construction shown, the stropping elements extend slightly farther radially from the axis of the member at one end than at. its 110 opposite end, so that the pressure against the side of the blade increases slightly from one end of the cutting edgeto the other and by operating upon a larger portion of the Any suitable means may be provided for rotating the members 6 and 7. In the form shown one end of the member 6 projects slightly beyond the end member 2 and a pinion 19 is mounted upon the projecting portion. A gear 20 is rotatably mounted upon members. The end of each arm is also prefa pin 13 or other suitable means upon the end meifiber arranged to mesh with the pinion 19. A crank or other convenient means 21 is provided u on the gear 20 for rotating the same so t at by turning the crank the member 6 will be rotated preferably at a speed considerably greater than the gear 20. j
. The blade 18- to be stropped or sharpened may be held in position to be operated upon by the stropping elements in any desired manner. In the form shown a pair of arms 22 and 23 are provided upon the end members 1 and 2 respectively each rigidly secured thereto in any suitable manner. The upper end of the arm 22 is provided with a central slot or recess 24extending longitudinally of the arm of suitable Width to permit any projecting portion, as-for example, the handle or other part upon, or attached to, a
blade to extend to the space beyond the end erably provided with a central depression 25 arranged to cooperate with a suitably formed transverse plate26 having its end formed to engage the recesses 25 to support the plate inposition and permitfits lateral movement. The extremities of the plate 26 are also preferably increased in width slightly as at 27-27 to provide suitable shoulders to engage the sides of the recesses 25 to prevent longitudinal movement of the member 26. In the preferred construction shown, aresilient clamp 28 is provided of suitable form to engage a blade intermediate its edges leaving sufficient space between the walls of fthe clamp and that portion of the blade extending into the clamp to permit a limited lateral movement of the edges of the blade so that while the blade is held firmly in the clamp, itscutting edge is free to move laterally to adjust itself to the stropping elements.
The clamp 28 may be adjustably secured to the plate 26 in any convenient manner. In the form shown, the clamp 28 is rigidly secured to a back plate 29 extending longitudinally beyond the ends of the clamp. A pair of posts or pins 3030"are provided upon the upper or rear side of the back 29 adapted to fit in suitable sockets 31-31 upon the plate 26. A set screw 32 or other convenient fasteniiig means is provided upon each of the sockets 31 adapted to engage a pin 30 when positioned in the sockets to firmly hold the same in position. In'the form shown a part 33 is provided upon the back 29 arranged to engage the extremity of a blade positionedin the clamp 28 to indicate proper position in the holder, and to prevent its longitudinal movement during the stropping operation. a
In the preferred construction a pin or projection 34 is provided upon the plate 26 adapted to coiiperate with a suitably formed slot 35 in the arm 23 to prevent rocking or tipping of the bar 26 when the device isgin operation.
In the form shown, a provided extending across the space between the members I and 2 and having a part at each end adapted to closelyfit above the extremities of the plate 26 to prevent its displacement from the recesses 25. A disk provided with a suitablyformed'notch or depression 41 in its. periphery is rigidly secured to the member 6. A part 39 is prolock or cover 37lisvided' upon one end of the lock. 37 adapted I 'to engage the notch L1 to prevent rotation of the members 6 and 7- while the lock 37 is I that after the blade holder is positioned in my device the lock 37 must be closed or moved into position to prevent displacement of the plate 26 before the stropping elements can be operated.
1 In the preferred construction a spring actuated dog 43 is provided to engage the teeth of the gear 8 or other convenient part upon the members so that the stropping elements cannot be rotated in a direction to out or injure the stropping surfaces nor a blade being sharpened by engagement of the stropping elements with the cutting edge of the blade. 7
Where it is desired to strop a blade narrower than that for which the clamp28 is in tended or where it is desirable for any cause to have the edge to be stropped project farther from the clamp 28, the distance piece 44 shown in Figs. 8 and 9 may be employed.
.In the preferred construction shown, the
