SAFETY RAZOR A NDBLADE Filed 001;,l 51, 1931 Patented May 2l, 1935 `lUNITED 4STATES PATEN r :OFFICE This invention relates to improvements .in
I safety razors and blades. l i
It is a primary object of the invention to pro-4 vide a razor frame 'with a cooperating blade '5 wherein the parts of therazor and blade will be properly guided during the assembling of the razor and wherein the blade will be securely and uniformly held in proper shaving position inthe frame.
It is a further object to provide a two-edged blade which will be of substantially universal application in being applied to various types of razor frames which may be constructed.
The above and other objects of the invention will appear more fully from the following description when considered in connection with the drawing in which: Fig. 1 is a longitudinal sectional view of one complete adaptation of my invention.
Fig. 2 is an-inner face view of the clamping plate shown in Fig. 1. f i w Fig. 3 is a face view of the blade employed.
Fig. 4 is an outer face view of the guard illustrated in Fig. 1. p
Figs. 5, 6 and 7 illustrate the application of the bladeshown in Fig. 3 to razors having various types of projections. t y
The razor framedisclosed herein comprises a hollow handle I5 and a head indicated generally at I2, the latter being arranged obliquely with respect tothe axis of the handle I0 and formed With a blade supporting guard` I4 and a clamping plate I6 movable toward or from the guard. In the particular form ofthe invention illustrated herein the guard I4 is rigidly and inseparably at-` tached to the handle I0 to provide atwof-piece razor wherein only theA clamping plate is separable from the guard and handle. It will be understood, however, that other constructions of razorframe Vmay be used in connection with my present invention. i
'I'he handle I0 is provided with an internally threaded attachment sleeve I8 having a forced fit into the thumb nut and peened over within the thumb nut so that these elements are permanently attached together. An attachment washer 22 is loosely received over the sleeve I8 Y 'to be rotatable thereon but is held against longitudinal movement between the thumb nut 20 and a transverse pin 24 passed through the sleeve I8. uThe washer 22 has a tight t within the interior of the hollow handle I0 but this connection is not permanent in that the thumb nut, sleeve and `washer 22 can be removed `from the handle I0 if sufficient force is applied thereto. The inner en'd of the sleeve I8 is internally screw-threaded as indicated'at 25 for receiving the screw-threaded shank of the attachment plate.
-The guard I4 which` is obliguelyarranged` with respect to the handle I0 is formed with alongitudinally extending abutment 26 for receiving a i blade over the same and anchoring. the blade against longitudinal orlateral movement thereon; The guard is also formed with a pilot` stud 2l placed only on one side of the axis of the razor for coaction with a corresponding opening Ain the clamping plate so that these elements will alwaysbe drawn to clamping positionwith the plate rotated to the proper angle with respect to the guard. i,
The central portionsV of the guard I4 and abutment are provided with an opening 28 for receiving 'the attachment shank for the plate E6, the' opening 28 having a squared section 29 andan outer tapered portion 3S leading to-the squared portion to permit the plate to be rotated in finding its proper location. The guard is also formed with recesses 32 adjacent the outer ends thereof forV receiving corresponding projections on the plate. y
The plate I 6 is provided with an attachment shank 34 rigidly connected to the plate, the main body of the shank 34 being squared or of other out-of-roundconstruction corresponding to the cross-section of the opening 29, the inner end of the shank having a screw threaded portion 35 received with the screw threads 25. 'I'he inner face of the plate I6 is recessed at 38 for receiving the abutment 26. The plate also includes an opening 3 7 on one side Vof the axis of the shank l34 vfor pilot pin 21 on the guard. The lugs 38 projecting inwardly from the cuter ends of the plates passintothe recesses 32 in the outer face of the guard, the projections 38 cooperating with the abutment 36 in spacing the blade received between the plate and guard. It is preferred to round the outer ends of the clamping plate as indicated at 39 so that no objectionable projections will be present. It is also preferred to remove a section of the material from the under face of the plate `as indicated at 40 so that any of the small burrs which may develop on the under face ofthe plate will not contact with the blade' and obstruct proper positioning of the same in ,the razor.
The blade indicated generally at 42 is formed with a `slotted opening 44 corresponding to the shape of the abutment 26 and lugs 38. The opening'is'thus formed with the relatively wide outer portions 45 and the central narrower portions blade l2 to the abutment of Figs. 2 lto 4 45, the material forming the opening 44 being inwardly bowed as at 4l to provide the wider and narrower sections of the slot. 'I'he Walls of the opening converge at 48 adjacent the Wider portions l5 of the slot the converging walls 4S forming the reduced passages 5G leading to the terminal enlargements 5! at thek ends of the slot. The section l5 of the slot lll is preferably only of a width suihcient to snugly` receive the shank M. t will be observed that the abutment 2S on the guard corresponds with the main body portion vof the slot 44 and that the projections 38 on the plate correspond with the terminal enlargements 5l of the slot as indicated in Figs. 2, 3 and 4.
The blade s2 is primarily designed to be supported upon the head l2 of therazor described above. The blade,`however,k is ofparticular usefulness in being adapted for use on various types of safety razors which may be constructed. There is accordingly illustrated diagrammatically in Figs. y*5 to 7 the application of the blade 42 to various styles of razors. The .application of the comprised in part by the projection 2S on the guard and in part by the lugs 3S on the plate will beV understood without further illustration. The two opposed'projections serve to firmly anchor the bladewhether it is rapplied first to either the guard or the plate and to doubly anchor the blade when the plate and guard are placed in the opposed relation in .which they are normally used (see Fig. 1).-
In Fig. 5 the blade ft2 is shown as applied to a razor frame by having the squared or diamond shaped projections 52 and a substantially circular attachment lug 5d. It will be observed that the slot 14 is received snugly over the anchoring projections 52 as well as over the attachment lug 54.
In Fig. 6 the blade 42 is shown as applied to a razor having an abutment in the form of a longitudinal bar 55.
In Fig. 7 there is illustrated a similar application of the blade 42 to a razor having circular anchoring projections 5S and a central circular attachment lug 58. When applied to this razor the lugs 56 are loosely received in the outer part of the wide portion 65 of the'opening in the blade, the central narrower portion 436 of the blade being received snugly over the anchoring lug 58. The snugness of the slot l over the lug 58 is suiiicient to prevent any objectionable looseness between the blade and the razor frame.
' The advantages of the above razor will be apparent from the above description. The blade can be received upon the abutment formed on vpilot lug 2l on the guard on one side only of the axis of the razor in conjunction with the corresponding opening in the plate not only guides the parts of the razor head into proper position but also advises the one who is using the razor as to the proper angular position of the plate on the guard. In this way the shank 34 may be rigidly formed. on the plate l@ as there would be no tendency in use to rotate the plates i6 to the wrong angular position in assembling the razor. The squared shank 34 may or may not be employed and if employed the shank serves to further -facilitate the placing of the plate on the guard in the proper angular position.
Any of the forms of blade disclosed herein coacts not only with the 'correspondingly shaped projections formed on thepguard and plate but also with various other styles of razors as indicated.
