UNITED STATES ALBERT W. 'STOPPEL, OF CHICAGO, ILLINOIS.
BLADE-STROPPING DEVICE.
Application filed October 31, 1925. Serial No. 65,987.
, the use of the invention.
Fig. 2 is a fragmentary sectional view taken longitudinally through the device.
Fig. 3 is a. cross section through Fig. 2 but with the parts in an altered position.
Fig. at is a fragmentary view illustrating the blade carrier in partially withdrawn position.
Like reference characters denote corresponding parts throughout the several views.
The reference numeral 1 denotes the casing, oblong in shape and having one rounded closed end 2 provided with the ring 3 adapted to be engaged with a hook 4 in a wall or other support. The front end of the casing is formed with a transverse perforation 5 to receive the strop 6 and the top of the casing with a perforation 7 for the win dow 8. The sides 9, 10 of the casing are formed respectively with the rounded outwardly bulged diametrically opposed portions 11, 12 perforated centrally to receive the rotary sleeve 13 extending transversely of the casing and provided with the head 14 to prevent its withdrawal from the casing in one direct-ion, said sleeve being formed with a longitudinally extending slot 15 extending from one end almost to the said head 14 and with an integral ear 16, adjacent its slotted end, provided with a button 17 that extends out through a semi-circular slot 18 formed in the bulged portion 11, said slot registering with a di'ametrical slot 19 in said portion 11.
The said, sleeve 13 is provided, adjacent the head 14:, with the diametrically opposed springs 20, 21 the outer ends of which are secured to the casing side 10 whereby said sleeve is yieldingly held against oscillation. A blade carrying shaft 22 is formed with recesses 23 separated by bosses 24 whereby a razor blade 25 of the Gillette type is carried, said blade lying in said recesses and the perforations of said blade receivin said bosses 24, said shaft 22 and blade being adapted for insertion in the said sleeve 13, the blade passing through the perforation 19 into the slot in said sleeve. By reference to Fig. 3 it will be noted that with the sleeve 13 in normal position, at which time the springs 20, 21 are'contracted, the button 17 is disposed in the slot 18 substantially in alignment with the slot 19. The blade 25 is introduced into or removed from the casing by manually turning the shaft 22 by its outer end until the button 17 is disposed in one end of the slot 18. This movement expands the springs 20, 21 and positionsthe blade in the plane of the slot 19 through which it will pass as the shaft 22 is manually withdrawn from the sleeve and casing. The springs 20, 21 will now re-position the sleeve 13 disposing the button again opposite the slot 19.
Referring again-to the strop 6 the same is, in efiect, an endless strop, the ends being connected by the leaves 26, 26 of a hinge, the pintle of said hinge pivotally carrying the handle 27. The strop is introduced into the casing, one side of the casing then being removed, and placed about the support roller 28 that extends transversely of the closed end of the casing, its axis being supported in the casing sides, said strop passing between a pair of spaced guide rolls 29, 29 disposed centrally and extending transversely of the casin and also between a similar pair of space guide rolls 30, 30'at the front end of the casing, said strop pass ing about the sleeve 13 and-blade 25, through the perforation 5 in the casing and about a roller 30 carried by a hand grip 30.
The strop is formed withthree spaced substantially cup- shaped perforations 31, 32 and 33, said perforations each being of a. diameter slightly greater than the length of the blade except at the contracted end of the perforation, the perforations 31 and 33 being equidistant from perforation 32.
In operation the device is supported at one end by the ring 3 and hook 4, the operator manually supports the other end by the hand grip 30' and with his other hand he moves the handle 27 to and from the casing 1. This movement may start from the position illustrated in Fig. 1 wherein the perforations 32 and 33 in the strop are aligned and the blade extending through both. The handle 27 will now be movedtoward the roller 30 thus positioning the blade as shown in Fig; 2 with the strop opervati vely engaging opposite sides of both edges of the blade until the perforation 31 is aligned withthe perforation 32; the blade will now protrude through both of said openings and the sprlngs 20, 21
will dispose it at right angles to the strop.
' The handle 27 is now at the end of its movement toward the roller 30 and its next movernent will return it into proximity to the casing, this movement inclining the blade 25 in a direction the reverse to that shown in Fig. 2 and permitting the strop to operatively engage with the relatively opposite sides of both cutting edges.
and away from the casing 1 stro'ps bothsi'des of each cutting edge of the blade until the blade is sharpened w'hen' it may be removed.
What is claimed is:- 1.' In a'blade stropping device, a casing open at one end, a support roller in said V casing, blade holding means within said casformed with a plurality of perforations adapted to align one with the other as they reach said blade holding n'reans, and then to receive the blade to reverse the position of the same, and an operating handle for said strop.
2*. In a blade stropping device, a slotted easing. open at one end, a support roller in saidc asing, blade-holding means within said casing yieldingly" retained in a predetermined position with respect thereto, said means comprising a rotary shaft carrying the blade and adapted together therewith for insertion or removalthrough said slot casing, a hand grip, a roller carried'thereby, an endless strop extending through the open end of said casing and engaging with said last named roller and the said support roller and associated with said blade-holding means, said strop being formed with a plurality of perforations adapted to align one with the other as they reach said blade-holding means and then'to receive the blade and This lIlOVGll'lGIltl of the handle 27 back and forth or toward reverse the position of the same, and an op erating handle for said strop.
3. In a blade stropping device, a slotted casing open at one end, a support roller in said casing, an oscillatory sleeve in said casing, slotted to receive the blade, springs connecting said casing and sleeve for yieldingly retaining the latter in a predetermined positionpa bu tonmovable with said sleeve and extending through a slot in said casing, a rotary shaft, adapted to telescope within said sleeve, recessed to receive the blade, a hand grip, a roller carried thereby, an endless strop extending through the open end of said casing and engagingwith said'la'st named roller and with the support roller and associated with i said blade-holding means, said strop being formed with three spaced perforations, two of said perforations being equidistant from the third and being adapted alternately to align with said third perforation in the plane of said sleeve to receive the blade to reverse the position of the same, and a handle for said strop.
4. In a blade stropping device, a slotted casing open at one end, a support roller in the closed end thereof, an oscillatory sleeve at the open end of said casing slotted ion-gitudinally to receive the blade, diametrically opposed contractile springs engaging. said sleeve and the casing, an earintegral with the slotted end of said sleeve, a button carried by said ear and extending through casing slot, a rotary shaft recessed to receive the blade and adapted for disposal in said sleeve, guide rollers in said cash-1 a hand grip, a roller carried thereby, an end less strop extending through the open end of said casing and'passing between said guide rollers and engaging with said, last nained roller and with said support roller, said stropbeing -associated withsai'd sleeve and formed with three spaced perforations, two of said perforations being equidistant from the third and being adapted alternately, as said strop is moved back and forth, to align with said third perforation, said strop engaging directly with the edges of the blade as it oscillates, the perforations in said strop receiving said blade in their aligned position to reverse the position of the blade and a handle for said strop. i
In testimony that I claim the foregoingas my own I have hereto affixed my signature.
