Application filed January 2819,6.'7Serin1i1\Io..84,269.v I,

'z The purpose; of this invention is to pro'- vide ,an improved Y and simplified `form of device .for sharpening blades,-such as safety razor blades, which can be collapsed into compact form for carrying in thepocketor toiletl case.v lIt consists ,in the elements and features; of construction shownI and described as indicated in the claims.

In the drawings f Figure 1 is a` perspective view otadevice embodying vthis invention in 4the'form for use,and illustrating theI manner of vhandling lthe strop and theblade in sharpening the latter. 4

Figure 2 is a rear side. elevation of the der-ice' collapsed for storing when out of use. Figure 3 is a section atthe line 3-3 on Figure 2 showing,` however, the handle set at operating position 'as in Figure 1 instead of folded intocollapse'd position as in Figure .2.

Figure 4 is affront side elevation ofthe device collapsed.

Figure 5y is a larged scale of the extensibleand collapsible connection between the ends of .the strop plate for flexing the latter, showing thesame at contracted position. t Figure 6 is a sectional direct side elevation of the implement.l with thestrop blade flexed. in fornilt'oruse, section being ymade at theV middle part of the length of the contractibleiand extensible connection ,through the locking feature. i,

.Figure 77's a sect'on at the line 7T-7 on Figure 6. v L g v 'Y he implement shown in the drawings comprise-s a spring plate,-10,l adapted to be iiexed as shown in Figures 1 and 6 into approximately half cylindrical form, and to react from such lexure to its normal straight or flat form, said spring plate having at the side which is flexed convex for service, covered with a strop leather, 11, or in any Way suitably surfaced Jfor sharpening a blade. The opposite ends of the spring plate are connected together by an extensible and contractible connection consisting, as shown, of two interlocking slides, 12 and 13, whose interlocking is eected by folding the lateral margins of the slide, 12, over the corresponding margins of the slide, 13, as may be seen in Figure 7 the remote ends of the two slides being hinged to the opposite ends respec* tively ot' the spring plate, 10, as may be understood mostk clearly from Figures 5 and detail section on an en-V ;p ATENT ovl'fFlxC El.

6. i, The interlockedslides are dimensioned v longitudinally fory lapping. upon each other a distance nearly ,half the length oteach when they are extended so as tov liejlat upon the back sideot' the straight-extended spring plate as seenin' Figure 3. y

The outer slide, 12, has an aperture, 14, i

near. its hinged end as ,seen inFigure 5,;and the inner slide, 13, is slitted as indicated at 15, `15,'to form a tongue, .16, whose Jfree end is reflexed upon itself as seen at 17, forming a prot-rusion from the under side .of the tongue which is dimensioned for engaging the aperture, 14, in the slide, 12, this vengagement occurring whentheslides are interlapped to the full extent contemplated for y drawing toward each other the oppositeendsof the spring platefor -lexingthe glatter to the curvedcondition for service as shown .in Figure l. A l

.Upon the outer or back side of the outer slide, 1, thereis pivotallyl mounted a stirrup or offset bracket, 20, vfor .carrying a handle, 21. The handle is securedto the stirrup byineanswof a headed bolt, A22, which is screwed through a suitablyA threaded aperture in the bracket, 20, and at the same time screwed into the end of theihaiidlefor permanent connection tothe latter. Tlie'under sideot the head22a, of the bolt when the latter is screwed in permanent` position into the handle. is spaced from the end of the handle a distance in excess of the thickness of the'bracket'through" which it is screwed ythe handle is extended perpendicular to the slides for use of the device as seen in Figures 1 and 3;y and the slide,13, has an aperture, 13b, which registers with the aperture, 12b, when the slides are interlapped for contracting the connection which they form between the ends of the spring plate for ilexing the latter to form for service; that is to say, at the interlapped position at which the tongue, 16, of theinner slide, 13, engages the aperture, 14, of the slide, 12, as seen in Figure 5; and when the slides are thus interlapped and locked for flexing the spring and strop surface, the handle having been swungfroni position shown in `Figure 2 lat against the back side of the slidesto position it perpendicular to the slides as seen in Figures l and 3, the handle is Screwed in through the bracket to thrust the head 22 of the bolt, 22 through the registered apertures, 12b and 13b of the slides, thereby, first and primarily,

securing the handle in its perpendicular posit-ion with respect to the slides, and sec- .ondly, securely l`locking the slides at vinterlapped and contracted posit-ion, supplement ing in fthis respect the service performed by the'engagementof the tongue, 13b, oi the slide, 13, with the aperture, l2",of the slide, l2.

"The mode of operation and use of the device will be understood from the foregoing description of ftheconstruction Without l;t'ur ther explanation.

1.An implement for `the purpose indicated and the like, comprising in `combination a spring plate suitaced at one side for Vsharpening purposes, and adapted to 'be flexed convex at that side; slidingly en,- gaged slides havingtheir remote ends hinged respectively -to the opposite ends of the spring plate, and extending at theiopposite side of said plate, and-means for "locking said slides at contracted `position for `holding the plate ilexed. y

2. An implement for the purpose indicated and the "like comprising in combination aV spring plate surfaced at one side for adapted by the :pivoting of themount to be set perpendicular to 'the spring plate, said outer slide having an aperture allgned with thehandle .at the .perpendicular position of the latter, the 'handlehaving a terminal and being adapted to-be screwed through the mount for engaging said terminal in said aperture ffor :locking .the handle at said perpendicular position. i

lIn the fconstruction defined `in Aclaim 2, the inner slide havingan-aperture positioned `'orlregistering with the aperture in the outer slide at the contracted position of said slides,

and theterminal of the handle `being dimeni s'ioned :fori-extending into said `aperture when screwed into the aperture o'i'lthe outer slide, whereby the =handle fat. `said perpendicular position serves to lock theslidesat contracted position. I y y f il. An implement `for the purpose .indicated and the Alike'comprisi'ng ai'spring plate having a strop leather Amounted upon `one tace and adapted to be curved convex at that face; interlockingslides Vhinged atftheir oppositevends tto the opposite ends of the springplate for extending along `the side of the latter-opposite thestrop leather and interlapped upon each other when thus extended upon the spring plate at straight extended position of the latter, theouter- `flapped slide `having at its outer Isidea Emount for a handle and an aperture opposite vsaid mount, the *handle being engaged with the mount for alignment with the aperture for protruding thereinto, the innerslide `having an aperture positioned for registering with the first mentioned aperture 'wheni'theslides are inter-lapped for `shortening the connection between theiriopposite'ends and bowing the spring plate, iand the handle being adapted to `be thrust through the registeredapertures lfoifloclx'ing the lslides `at `interlapped and spring-,plate bowing position.

"In 'testimony whereof I have hereunto set my hand at Chicago, Illinois, this 25th `day of January, i926. l
