To all whom it may concern: I
Be it knownthat I, SIDNEY L. 'LONG, a
citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Devices for Stropping Razors, of which the following is a. specification. I
My invention relates to devices for stropping razors, and particularly so-called safety razors; and its object is to provide a 3 simple, cheap, and efficient stropping device adapted to be successfullyoperated by an unskilled and un'experienced person.
My improvements are illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of a razor I stropping deviceor machine embodying my screw and thumb nut 3; v The operating mal or inoperative position.
improvements. -Fig. 2 is a vertical lon itudinal sectional view of the device of F g. 1. Fig. 3 is a plan view ofv the same, with the upper strop partly removed. Fig. 4 is an enlarged view of the middle portion of Fig.- 2, with "portions broken away, and showing a razor blade and its holder in norsim'ilar view showing the blade held'in contact with the upper strop. .Fig. 6 is a side elevation, showing the side of the device opposite' that shownin Fig. 1. Figs. 7 and. 8 are detailviews of the cross-.hea'dand its guides employed for actuating the razorholder, showing the, trip for the latter in its 'two extreme positions. Fig. 9is a detailof the cross-head. And Figs.,10, 11, and 12 -are detail views of the razor clamp or holderji v In the drawings 1 designates a frame or casing having two sides and a bottom, but
open at the ends and top, and preferably made of metal; and 2 a handle attached to the bottom of the casing, preferably by a shaft 4 is journaled in the sides near one end of the frame and on the opposite ends of the shaftare crank arms 5'and 6; and the. crank 5 is provided with a handle 7 forturnin the shaft to operate the device. -Between t e latter crank and the casingadriving pulley 8', having two grooves, is secured on the shaft; and belts 9 and 10 extend therefrom. to two pulleys 11 and 12 onv shafts 13 and 14: journaled, one above the other near the other ends of the frame, one ofthe belts, being crossed td' cause the two driven pulleys tgrun in opposite directions.
Fig. 5 is' a.
and the shafts, 13, 14, 15, and 16, are provided with rollers, 17, 18, 19 ,and 20,'on which are arranged the two endless strops 21 and 22, one above the other, '=with a suitable space between their adjacent surfaces for the razor holdin device. It will be apparent that under this! construction the operatlon of the crank shaft will cause the ad.-
jacent belt surfaces-to travel in the sarrle direction.
For convenlence' of access to the interior curved slots 23 are provided 1n the casing Corresponding shafts15 and 16 are journaled near the opposite endlof the casing,
for inserting and removing the ends of the shaft 15- (or the trunnions of the roller 19), so that the upper strop can be readily removed, as indicated in Fig. '3.
intermediate the-two .strops, and its construction is as follows: A base plate 28 is centrally pivoted to '-the frame, sides by- I means of a rocking'rod 29, and is provided at its'oppositeedges witha pair of inwardly projectlng llps 3,0 for receiving a loose upper plate, or clamp jaw, 31. The razor blade .32 is placed between these two plates or jaws, and the upper jaw is held in place and adapted/to exert the required pressure upon the bla e by a lever 33 pivoted by a pm'tle 34'to 'thelg'aw 31- and provided with, a lateral flange or short lever arm 35 which bears upon thelsurface of the under jaw: 28,
when the longer lever arm is'turned down-- ward, as from the osition shown in Fig 10 to'that shown in ig. 11. As the lips' 30 offer resistance-to the upwardmovement of the pivoted end of the jaw the other end obviously will exert pressure upon the razor blade. By turning the :levertdthdpositioh shown by'broken lines in Fig.1!) the aw. 31 and its lever can lie-"removedforiplacing' or removing the blade. coil spring36', with one endconnected toafstud 37 on't'he frame loo and the other connected to alaterally ex.- 1
tending pin.38 secured to1-the jaw plate 28, serves to hold the clamp and'blade in middle or normal position, asshown in Fig. 4, when the machine is not-in operation.
Forrocking. the clamp or holder to preis. rocations of the cross-head carry the block seiit -t-he blade alternation to the strops,
the 'pin' 38'is projected through a slot39 in the casing I to position to be engaged and i the 'reci' rocations and is connected by a pitman. 42 to the crank-arm 6 'on the driving-shaft, so as to jreciprocate when the'strops are operated.
On the inner side of the cross-head is formed f r-attached a block 43 of rhomboidal shape jand'arran'ged in position to engage the'pin i 3 8'with itsfinclinediends- 44 and thereby raise or lower it tothe plane of the upper orlower surface of. the block. The recip- -43-beyond the points of contact with the pin 38 and when'the latter is thus disengaged the tensionof'the spring 36 upon the. pin
restores itand the clamp itserves'to vibrate p to normal or middle position, and the pin is then in position tobe again engagedand actuated by the block. By these. means the 1 clamp is tilted on its "axis to opposite inclinations and there'heldpredetermined and equal periods, during the movements of the .'block- 43 past the pin or trip 38, and the ;razo r is thus presented in alternation to the aetion'of the upperand lower 'strops' at provided for locking the equal inclinationsand during equal periods .0 operation. To-prevent the strops from run in reverse direction and being cut by t e razor a ratchet and do device 45 is against such reverse movement.
