FERDINAND G. HENRY, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS,

TO WALDEN KNIFE COMPANY, OF WAL YORK.

DEN, NEW YORK, A. CORPORATO'N OF NEW STR-OPPING MACHINE.

Application filed July 16,

To all whom t may concern.'

Be it known that I, FERDINAND G. HENRY, a citizen of the United States, residing atk New York, N. Y., have invented certain new and useful improvements in Stropping Ma-` chines, of which the following is a clear, full, and exact description.

This invention relates to stropping ma chines, and is herein shown as embodied in a stropping machine designed to strop the thin removable razor blades now employed with various types of safety razors. It will be understood, however, that the invention is not restricted to the particular embodiment or uses herein illustrated and described, and that many features of the invention are of general utility in 'the art to which the invention relates.

A general object of the invention is to provide a stropping machine which will automatically present the work to be stropped to the stropping mechanism, effect the stropping of the work, and then remove it from the stropping mechanism.

More particularly, the invention aims to` provide means for automaticallypresenting, in succession, to a stropping mechanism a series of thin blades to be stropped, effecting the stropping of these blades automatically, then removing them from the stropping mechanism, and preferably delivering them to a stack or galley in such manner that they can readily be handled for suoli further operations as are to be performed on or in con nection with them. I

An important feature of the invention is the novel arrangement of the strops, whereby the abrasive cut of each is in a direction oblique to the cutting edge of the blade or other work to be stropped.

Another important feature of the invention is the novel means for delivering the blades to the stropping mechanism by an endwise movementthat is, by a movement parallel to the cutting edge. n

The invention also comprises novel means for presenting a supply of blades to the blade l feeding mechanism after the stropping operf ation, and retaining 'them in convenient con-` dition for presentation to other machines, or even for manual manipulation.

Other important features and objects of the invention will appear from the following 14920. Serial No. 396,667.

The illustrated machine comprises side frame castings 2, connected by cross-rods Ll,

these castings supporting a table top 6, prefy erably having a guard` flange 8, upon which top are carried the various supports for the blade holding galleys,pblade feeding mecha? nism, blade holder, and the upper supports for the endless blade strops. v

The stropping means of the present invention comprises two endless blade strops 10, 12, the strop 10 passing over a driving pulley 14, carried upon a shaft 16, having its bearings in a bracket 18, attachedto the underside of the table top 6, the strop 10 also passing overlan idler pulley 20, mounted l, partsl of this view being CFI upon a shaft 22, carried in a yoke 24, having a threaded extension 26, adjustably held upon a cross-piece 2 8 by nuts.;.30 upon oppo.- site sides of the crosspiece. The crosspiece 28 is carried upon upright supports 32 mounted uponY the tabletop 6.

The shaftvlcanrieslloutside the bearingsiny bracket 18 a grooved pulley 34, over which passes a belt 86 traveling in the groove of a. Second grooved pulley 38 upon the main driving shaft 40 of the machine. Themain driving shaft 40 of the machine has its bearings in brackets 42' and'K 44preferably cast' integrall with the associated' frame member 2, and at one end the shaft isprovidedl with a driving pulley 46'connectedto any suitable source offpower, and'either directly connectedf to the shaft 40V through suitable clutch mechanism 48^eontrolled`-by alever 50, this mechanism notI being specifically shownv and descriloedysincel it` constitutes no partv ofrthe present invention.

The other strop 12 likewise passes. over, a guide pulley 52supp-orted upon Va shaft hav- 'l ing its bearings in a,brae,ket54, and'earrying at one end a 'grooved pulley 564v connected by a belt 58 to a second grooved pulley 60 onl. the driving shaft4 40, the strop 12 also passingover an idler pulley 62-earried upon a shaft 64, in a yoke 66, having a threaded extension68, adjustably held in the cross.

piece 2,8loyEl nuts 70, in the same. mannerI as the extension 26pofrthe yoke 24:

By suitably adjusting the yokes 24, and;

66,upon the crosspiece 28, the desired degree oftautness may be given to the strops. The proper alinement of the yokes is preferably r'naintained'by guide-rods 72rextending. from th-e upper ends yof the yokes 24v and-66, and guided inopenings in the crosspiece 2,8.

The- strops 10 and 12 ,preferably travel in planes substantially parallel to each'V other invtheir operative paths. of travel andare preferably spacediap'art such a distance that the blade heldin-ian oscillating blade holder 74, arranged midway` between the strops to osoillate about an axis substantially parallel 'to the planes of the strops in this region., Will be presented to each strop at suoli anv inclination to its plane as will produce the desiredbevel upon the blade from the stropping operation, the blade holderbeing prefi erably operated to presentV one side Pofthe blade to one strop, and thento oscillate linto position to present the other side` of the blade tothe other strop, the blade, being preferably given equal'bevels upon its two.

sides, although it will be understood that the invention is not restricted in this respect. p

vThe blade holder 74 .as shown particularly in Figs. l and;5v of the drawings, is carried upon arockshaft 76 having its bearings in ears 78 and 80, depending respectively trom the supports 82 .and 84, upon which' are carried the supply and receiving galleys 86 and 88 and also the blade-guide and fceding mechanism hereinaften to be described. The blade holder itself, as shown in Fig. 6 of the drawings. comprises a wedge-shaped piecevhaving a blade receiving slot 90 in its upper edge, this slot being'l somewhat enlarged at its blade receiving end, as shown at: 925s@ as to facilitate guiding the blades into the holder. Spring blade retaining j aWs94 projectI through transverse openings 96 into the slotk90 to such an extent that the blade forced endwise into the slot must engage and-press these jaws apart, thus causing thev jaws to hold the blade firmly in the holder 74 for the stropping` operation. The construction of the blade holder and the mannerof"deliveringblades into the holder constitute important features ofthepresent invention.

The blade holder isrigid' with therockshaft 76, and is rocked by saidlshaftf to present7 the blade first to one strop and-then the other'by means hereinafter to be described, this means preferably stopping with the blade holder in the position shown in Fig. 5. In this position it willbe notedlthat the blade holder iscentered for the feeding operation by means ofl a ball 98 pressed by a spring 100 into a notch 102 in one of the blade guidesA 104. Inthis position ofl the blade holder, itI will be seenthat the slot il() ofthe blade holder is in line with `the guide- Way 106 in the guide 104, in which guide- Way the bladel feeding slide 108 travels. The slide 108, which is preferably a strip -olf steel of approximately the thickness-or possibly slightly more or less than the thickness-ofthe blade to vbe fed, is connected to athreadedextension 110 adjustably held by means of nuts 114 in a slide 116, traveling upon a guide` rod'118, carried-by a bracket on the table 6, anda secondbracket' l22 on oneof the uprights 32. Theslid-e 108 is operated by mechanism, hereinafter to be described, first to push the razor blade along the guide-way 106 into the slot 00 in the blade holder 74, then to withdraw slightly while the blade holder oscillates between the strops to present the blade alternately lirst to one strop and then to the other, and then` after the stropping operation-when the blade holder has returned to the position shown in Fig. -again to move forward and to force the` blade from theslot 90 in the blade holder 7 4, into the guide-Way 124, in a second guide 126, from which the blade is then pushed by an oscillating pusher 128 into the receiving galley 88, the pusher 128 being segment-shaped, having depending lugs 130 Which increase the width of its pushing face. and being carried upon an arm 182 attached to a rockshaft-184, `having its bearings in brackets 136'upon the table top 6.

The blade feeding mechanism, the blade Sli ill)

lou

lll)

of the cam.

holder, and the pusher for pushing the blades into the receiving galley are operated from cams carried upon a transverse earn shaft 188 driven from the main shaft 40 by n'ieans of a worm 140 engaging a worin wheel 142 upon the cani shaft 188. Extending parallel to the camshaft 138 is a stationary shaft 144, upon which are mounted several levers which cooperate with the cams upon the cam shaft 188. l

The feeding slide 108 is operated from an edge cam 146 on the cam shaft 138, this cam engaging a cam roll 148 upon a lever 150 fulcrumed upon the stationary shaft 144 and forked at its upper end at 152 to embrace the slide 116 which it engages between lugs 154 upon the two sides of said slide. .p lt will be noted that cam 146 (see Fig. 9 of the drawings) has a concentric portion 156, which is the part that is engaging the cam. roll 148, while the stropping operation is taking place. Following this concentric portion in the direction of rotation of the cam is the highest point 158 on the cam, which effects the blade ejecting movement of the slide 108-that is, the movement that forces the blade from the slot 90 in the holder 74 in front of the pusher 128 into position to be pushed Ainto the galley 88.

* Following the highest point 158 on the cam is the lowest point 160, which permits the slide 108 to withdraw beyond the delivery end of the galley 86 to engage another blade to be moved intok the slot 90 in the blade holder. rllhis movement of the blade into the blade holder is effected by the part 162 of the cam, following whichit will be noted there is a slight withdrawalmovement down to the level of the concentric part 156 The cam roll 148 is held in engagement with the cam 146, to 'cause the lever 150, to follow the curvature of the cam, by the action of a spring 164, connected at one end to the lower end of the lever 150, and at its other end to one of the cross-rods of the machine frame.

The oscillation of the blade holder 74 is effected from an edge cam 166 on the cam shaft 138 by connections now to be described. Upon one arm 168 of a bell-crank lever,

fulcrumed on the stationary shaft 144, is car! ried a cam roll 170 engaging the cam 168, this cam roll being held in engagement with said cam by means of a spring 172 connected at one end to the other arm 174. of said bell-crank lever, and at its other end to one of the cross-rods 4 of the machine frame. The arm 174 of said bell-crank lever is also connected by a link 176 `to an arm 178 of a second bell-crank fulcrumed upon a stationary shaft 180 carried by brackets 182, the other arm 184 of the last` mentioned bell-crank having its end bored to receive a rod 186 pivotally connected at `its upper end to an arm 188 attached to one end of the rockshaft 76 upon which the blade holder 74 is carried. A. yielding connection is provided, between the bell-crank arm 184 and the rod 186, comprising springs 190 and 192 surrounding the rod 186 above and4 below the arm 184 and confined between a collar 194 fastened to the rod 186 above the arm 184 and nuts 196 screwed upon the lower end of the rod. The stroke imparted to the arm 184 by the cam 166 is preferably' more than enough to oscillate the blade holder from one strop to the other, the remainder of the stroke being taken up by one or the other of the springs 190, 192, thus placing a yielding pressure upon the blade as it is held against the strop. The amount of this pressure cany be varied by adjusting the nuts 196.

The pusher 128 is operated from a cam 198 `carried on the cam shaft 138, this canikl i' engaging the cam roll 200 on the upper end of the lever 202 fulcrumed on the stationary shaft 144. Cam roll 200 is held against the cam 198 by the action of a spring 204 con-- nected at one end to the lower end of the lever 202, and at its other end to one of the frame cross-rods 4. A link 206 connects the lower arm of the lever 202 to one arm 208 of a bell-crank fulcrumed on the stationaryshaft 180, the other arm r210 of said bell-crank being connected by link 212 to an arm 214 on the rockshaft 184, which carries the Vpusher 128. f

From the foregoing description of the connection between the pusher 128 and cam 198, it will be seen that the blade pushing movement of the pusher is edected by the action of the spring204, which causes the cam roll 200 to follow the shape of the cam 198. There is thus no danger of breakage of 'the machine in the event of clogging, due

to a blade becoming misplaced in the guideway. f

The blades to be operated upon are preferably carried to the machine in a portable galley, such as shown iin Figs. 2 and 8, the

galley in which the supply of blades to be treated is held being preferably identical in construction with that in which the blades are to be received after treatment,

whereby these galleys may be carried from one to another of a series of machines which I have designed for use in the manufacture of razor blades, the receiving galley of one machineMafter being filled-serving as the supply galley of the next machine, and vice versa.. These galley/'s are placed horizontally in the machine, being carried upon the supports 82 and 84 and, as shown, are located between pins 216 upon these supports and the respective guides 104 and 126. As shown in Fig. 8 of the drawings, each` galley has at its end---which serves both as a delivery I end and a receiving enr *spring retaining pawls 218 having shoulders 220 normally lou Ilo

projected over the side edges of the endnios't blade in the' galley. To facilitate delivery of the blades to the feeding mechanism, the: guide 104:v is provided-uponits face adjacent to the galley' S6 which holds'- the blades to be stropiiedwith pair of beveled pins or lugs 2.22, which engage correspondingly beveled faces of the pawls 219i blade in the line of blades inthe galley;

this armbeing carried` by a slide 226 guided on rod 228. The arm 224 is held constantly pressed against the endniostY blade in the line by the' action of a counterweighti230, carried on a cord 282, and passing over a pulley 234iand about a second pulley 236 nearv the forward end of the galley, whereby the weight ten-ds to pull the slide 226 toward the forward end of the galley.

llVhen one ofthe galleys is used as a receiving galley, the spring pawls 218 are left inl their normal position,l no spreading' means being provided? upon the guide 126,.

and therefore each blade must 'be pushed past the retaining shoulders 2.20 on the p'awls 218 by the'pusher128.V In the receiving galley it is only necessary to provide a sli'dable weight, such as the weight 238 shown in Fig.. 2,y this weigh-tv being forced alongv the galley by the action of the pusher 128 as it pushes thesuccessiive blades past the shoulders 220off the pawls 218.4

From the foregoing' description, the opl eration of the machine will readily be understood. As soon as the clutch 48 is operated to connect the pulley 46 with the driving shaft 16, thev endless st-rops 1() and 12 will be driven. by their driving pulleys 1l and 52, which in turn are driven from the shaft s()` by the` belts 36 and 58', these stropspreferably passing over backing plates 246 and 242 in the regionv where the stropping` operation ltralies place.

Starting the machine causes the cam shaft 138 tof rotate through its worm and gear' connection. with the sha-ft 40, whereby the feeding." sli-de willv be operated to engage theblade which has been forced into the guide 104l by the action of the' ounterweight 236 upon the arni224, and willy move this blade along. the guide into' thel slot 90 of the blade holder and between the spring fingers 94; Ags the `feeding slide 10S withdraws for a slight distance-but not enough to: uncover the mouth of the `galley SG-the blade holder will be oscillated by its connections with the cam 166 to carry the blade held between the spring fingers 94 in the slot 90, first against one of the strops 10, 12 and their against the other.

The stropping operation having been completed, the blade holder T-ilmoves to its intermediate position shown in Fig. .1, in which the slot' 90 is again in line with. the guide-ways 166 and 124i, at which time the cam roll 148 will ride upon the highest point 15S of the cam 146, and the slide 106 will be moved to eject the blade from the slot El() in the blade holder 7l, the blade being. carried forward into the guide 1241 until it is in line' with the pusher 128, which then op erates to push it past the spring shoulders 220 on the spring pawls- 21S` into the receiving galley 8S, this operation forcing the weight 288 along the galley 8S a distance equal t-o the thickness of one blade. In the meantime, the slide lO-following the movement of the cam roll M8 into the depression 160 of the cani 14,-6-has withdrawn far enoughv to uncover the end of the galley 86, thus permitting the weight 230 to act upon the arm 224 to force another blade into the guide-way 106 in front of the slide 10S. The operation is then repeated untill either the supply of blades is exhausted, or the clutch 48 is operated to disconnect the driving pulley 16 from the shaft l0.
