.SPECIFICATION forming part of Letters Patent No. 469,893, dated March 1, 1892.
Application filed May 28, 1891. Serial No. 394,364. (No model.)
To all whom it may concern:
Be it known that I, OTTO W. CASTNER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements-in Razor-Strops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,- and to letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in that class of razor-strops commonly known as suspension-strops, and has for its object to provide a cushioned razor-strop of the character mentioned of simple design, the eifect'- ive surfaces of which will not become curved or warped out of shape or drawn to 'such an extent as to impair their operation or become broken when the tension is increased.
In strops heretofore made the pads or cushions and the part forming the stropping-surface were under the control of the tension device, so that when the tension of the'stropping part was increased the cushion or pad was correspondingly extended, and when the tension was decreased the stropping part, by
' reason of its resiliency, would return to its normal position, while the pad or cushion, owing to lack of resiliency, would remain in its stretched condition, leaving the stropping-l surface with less material under it after each operation. I'propose to remedy this objection by making the pad or cushion wholly independent of the control of the tension-adjusting mechanism, so that when the stroppingsurface is stretched the position or length of the pad or cushion will not be altered. The invention therefore consists of constructions and combinations whereby this result is accomplished, and of minor details, all as will hereinafter be set forth .in the specification, and pointed out in the claims.
In the accompanying drawings, Figure l is a longitudinal section through a razor-strop constructed in accordance with my invention. Fig. 2 is a transverse section on the line Fig. l. Fig. 3 is a perspective sectional view of the strop from the handle end; Fig. 4, a l detail in section, showing the manner of connecting the leather and canvas sections.
Like letters of reference indicate the same parts.
The frame-work or tension-adjusting portion of the strop may be of any desired construction, the ordinary form shown being preferred, however, and consists of the two end 6o bridge-pieces A A, around which the strop proper passes, the rods a ct, abutting against the outer bridge-piece, passing through the inner bridge-piece and connected by the crosspiece a and the screw-shaft A', carrying the 65 A handle and passing through the cross-piece c and engaging a screw-threaded aperture in the inner bridge-piece. Vith this construction, when the handle and screw-threaded shaft are turned the bridge-pieces are moved 7o toward or from each other, as will be readily j understood.
As `before stated, the strops proper are padded and so constructed as to prevent any undue strain being brought to bear on the stropping surfaces or pads themselves. At the same time the said pads are kept extended and in proper condition for use under all conditions, and in order to accomplish these desirable ends a relatively heavy strap or ten- 8o ,sion band is provided, which passes around both of the bridge-pieces and practically takes up all the strain, and the pads are mounted on this tension-strap, being kept extended and taut thereby.
In the drawings, C indicates the tension or supporting strap, made of relatively heavy, and thick material of substantially thewidth of the strop and passes around both of the.; bridge-pieces, the ends being united and 9o lapped at the handle end, where the rodspass through the same to afford additional security, practically forming an endless band. This strap C is covered by a sheet of any suitable stropping material E, havingastrop- 95 ping -surface, and preferably made in the form of an endless tube, which wholly incloses strap C. The longitudinal edges of the covering E are brought together under the strap C, as at e. (See Fig. 2.) When roo formed in the manner shown, the strop `is preferably provided with two stropping-surfaces of dierent material. In the present instance one is composed of a leather tube and the other of canvas, the former having its stropping-surface coated with a suitable abrading material and the other also properly treated to give the best results, The
ends of these tubes a're'secured together by inserting the ends of one into the ends of the other. In the present instance theends of the canvas tube are inserted in the ends of the leather tube, both being of sufficient M length to carry them partly around the vbridge-pieces to give the jointthe necessary strength. The covering,r willthus beun` der the control of the tension-adjusting d'evic'e. Between the upper part of the coverin'gandl upper'sid'e of the tensienstrap i'sthe pad oi cushion 19,06 any ordinary or preu fet-*red* material, the ends and` edges being. taV pered or thinned down to give proper slope to thestropping-snrace of thecover; The pad or* eushionl rests uponthe strapG, andlitsrends terminate witln the ends of the stro'ppin alsor` fabefsof that its' ends willl notoverlap the' bridge; and thus beVl undercontrol of t-heten'- siondeviee. In other wordsglthe' pad or cushfioni deesnot extend toK the bridge-pieces, which press; against they cover and the strap alilicll ed 0f the strop and Would Stretch the pa'dior cushion if. the latter overlapped thefbridgeip-ieees; Inside of the' whole band. time torlned asecon'd or finishing"strapy F is placed; and` servesas' an additional supportforthe'pads; bntmore particularly'as-a;bi'nld'er i'orthel edgesof the sheetsl which? form the stropping-surfaces after they passy beneathi thefsnpportingstrap', givin-g5 aneatantl substantiat finish-to they whfole strop*7 the edgesof the? inishingstrop of course being.' beveledl dovnto make neat joints at each side.
It will' of course.befund'erstoedI thattlhe spe-A eifefs't'rueture jrnst described may be changed considerably and; the pads formed and secured in; pbs'itioni ifn' any well-known manner com` :nonn to strcps of the n'cnfsuspension classwithout* departing from they spirit of my in*- ven'tiomit only being' essential that ai sup'- pofting'and tension strap be employed to relieve the direct strain on the stroppinglsulrfaces;I although said pads and surfaces should be` soY constructed as to be kept reasonably tant in* order tofpreveutwrinkling or working out'- o'f shape.
Over the endsand outside of all the parts the usual iinishin'gloops-G-y are app`1ied,if de'- sired, toaft'ord a" little additional strength at the points Where the partsl join .and also to cover up the ends or rough edges of the tubes.
The suspended tension and` supporting strap C, it will be seen, is of substantially the width of the strop, and in addition to relieving the tension on the pads and surfaces serves to hold thesame' extended laterally, preventing all danger of the strop becoming .warped or bent out of shape when worn or through rough usage.
By employing the padded surfaces the wellknownfadvantages incident to the use of the same are secured, and by making the strop a suspension'andl adjustable one the same may be held as taut as desired without impairing the stropping: qualitiesinthe leas-t.
