Figure 15 is a fragmentary plan View with parts in section, showing the form illustrated in Figures 13 and 14.

Referring more particularly to the drawings, and especially to Figures 1 to 8, inclusive, I have shown my razor as comprising a body member 16 of elongated rectangular shape and of platelike form with its side edges formed with guards defined by a series of curved prongs 1'?. The upper or outer face of this body is longitudinally .g grooved, as at 18, this groove being probably actually formed by pressing out the metal, the resultant hump or ridge at the underside being indicated at 19. The purpose of the groove is to cooperate with means on the cap to be de- ,iscribed for securing the blade properly in position, as will be explained.

Carried by the body 16 and preferably inseparable therefrom but movable relative thereto is a handle 20 of cylindrical form having one 40. end reduced to define a neck 21 terminating in aflange Yor head 22 located at the underside of the body and connected thereto for rotation with respectv thereto by means of a plate 23 on the underside of the body having an inwardly ex- 45,tendingl1iange 24 underlying the head or flange 2,2. Y This therefore constitutes a swivel connection. This swiveled end of the handle is formed witha threaded socket 25 registering with or in coaxial relation to an opening 26 in the body. g Where the plate 23 is attached, the ridge 19, if provided, is necessarily interrupted, as shown in Figure 5.

The razor further includes a cap 27 between which and the body 16 is arranged the blade 28 5 5 which is intended to be one of the numerous makes of the Gillette type on the market. This cap is of` elongated rectangular shape and is concavo-convex in cross section and of substantially the same dimensions as the body 16, ig- Gounoring the prongs, that is to say of the same length as the body and of a width corresponding substantially to the width thereof at the base of the prongs on the opposite sides. In razors of this type which are well known to the trade the cap is held in place simply by the provision of a threaded stud thereon passing through a hole in the body and engaged within a threaded socket in the handle corresponding to the socket 25 in the present instance. However, as it is an 7o; important feature of my invention to maintain the cap .and the body in permanently associated but relatively movable relation, I provide arms 29 located at opposite ends of the body and pivoted thereto as at 30, these arms having their '(5 `other ends pivoted at 31 to the ends of the cap 27. It is highly desirable that the cap when released from clamping engagement be maintained in elevated position with reference to the body portion and to effect this I provide at each end of the body a small leaf spring 32 located at a cut-away portion 33 and which has one end anchored within a slot 34 at one end of the cutaway portion and which has its other end anchored within a slot 35 and in a lug 36 on the arm 29. This spring arrangement and mounting are such that the arms 29 normally have their free ends urged away from the body, thereby lifting the cap 27 with respect to the latter. The cap is shown as having its corners provided with the usual lugs 37 engaging within the cutaway corners 38 of the blade, and as further having a longitudinally extending rib 39 engaging within the usual slot 40 in the blade, this rib being opposite the groove 18. At its center the underside of the cap carries the usual threaded stud 41 adapted to pass through the opening 26 and to be received within the threaded socket 25.

It will be observed that the cap is freely swingable with respect to the body and, viewing Figures 1, 2 and 3 in sequence, the action will be readily seen. When the razor is in use the blade 28 is clamped rmly between the body 16 and the cap and is flexed owing to the concavity of the inner face of the latter which cooperates with 105 the convexity of the outer face of the former. The edges of the blade project beyond the body so as to be operative where exposed between the prongs 17 when the razor is used in the customary manner. When it is desired to clean the 110 razor or remove an old blade or put in a new one, it is first necessary to rotate the handle 20 in a counter-clockwise direction whereupon the stud 41 Will be unscrewed from within the socket 25. The springs 32 then maintain the arms 29 and 115 consequently the cap, the latter carrying the blade with it, away from the body as shown in Figure 2. The user then engages his thumb and a finger against the projecting ends of the blade and swings it, together with the cap, upwardly 120 and outwardly with' respect tothe body, as shown in Figure 3, whereupon the blade may be very quickly and easily removed and replaced by a new one. If it is merely desired to cleanse the parts, it is not necessary to open up the device fully as it may be simply partly opened and held under a stream of water from a faucet. The great importance in providing the springs to maintain the cap in elevated position with respect to the body is that when the cap is swung into the open position and subsequently swung back, the edge of the blade will clear or be spaced from the body so as not to be abraded and dulled by contact therewith. Moreover this maintenance of the axis about which the cap is swung, in this elevated position, is important in that it serves, when the cap swings toward its closed position with respect to the body, to assure return cf the elements of the screw means to the same position they occupied when disengaged prior to swinging of the cap and therefore into reengaging relation with their axes substantially alined.

In the form of the invention disclosed in Figures 9 to 12, inclusive, the general structure is the same as that above described except that 145 there is a different spring arrangement for maintaining the cap elevated with respect to the body after the handle is unscrewed. Referring to these figures in detail, the numeral 16a represents the body which is identically the same as the 150 body 16 above described except that the cutaway portio-ns 33 are not necessary. There are the same prongs 17, the groove 1.8, projection 19, handle 20, neck 21, head 22, retaining member 23, flange 24, and socket 25, as in the rst described form. Likewise, the cap 27 with is corder 45 and they both engage against 'the ends of an elongated leaf spring 46 secured against the underside of the body 16a.

This lform operates in identically the same manner as the rst described form in so far `as broad principles are concerned. The point is that as the heels 45 are inclined with respect to the longitudinal axes or center lines of the arms 42 there is a `tendency for the springs 46 to swing these arms 42, and consequently the cap 27, carrying the blade, away from the body 16e after the handle 20 is turned counter-clockwise to disconnect the socket 25 from the stud 41. The action brought about by the springs 46 cooperating with the arms is for the same purpose as in the first described form of the invention, namely,

to prevent contact of the edge of the blade 28 with the body 16a when the cap is swung into open position and to return the screw elements, that is the stud 41 and socket 25, when the cap is swung in closed relation to the body, to the same position these elements occupied when last released so as to assure their axial alinement for reengagement.

In Figures 13 to 15, inclusive, I have illustrated another form of the invention in which means Ais provided for shifting the cap transversely with' respect to the body. In both of the first described forms it should be noted that on account of the swinging movement of the cap with respect to the body it is necessary either to Amake the opening 26 comparatively large or else `to bevel off the end of the stud 41 so as to avoid interference with the edge of the opening. To avoid having the hole 26 excessively large or cutting away any portion of the end of the stud 41, this last modification may be resorted to. Referring to this form in detail, it will be noted that I have shown a body 161 corresponding to the bodies 16 and 16a and similarly provided with prongs 17, groove -18 and ridge 19. Identically the same cap 27, with its details, is provided as in the first described forms. The difference in this form resides in the spring and arm means for maintaining the cap 27 away from the body when the handle is unscrewed. Actually, I provide at each end of the body an arm 47 pivoted at one end, as shown at 48, to the cap and having its other end slotted at 49 for the passage of a screw 50, or the like, which passes into the body 16h. The spring means comprises a spring member 51, conveniently a piece of spring wire of proper gauge, having one end tting within a recess 52 in the arm 47 Vand its other end formed as an eye 53 through which the screw 50 passes. The body V `16b is formed with a cut-away portion 54 at one end of whichis an inclined ledge 55 with which cooperates a similarly inclined shoulder 56 on the arm 47. The inclined surfaces 55-and 56 lead to shoulders 57 and 58, respectively, on the body and arm. i

In general, the operation -of lthis form is the same as that of the `two preceding forms, that is to say, when the Vhandle is -in tightened relation to thecap the .latter holds the blade flexed between itself and fthe body, Vthe surfaces or shoulders 57 and 58 being then in abutting engagement. Whenfitisdesired to open .the razor to change the blade, unscrewing of the handle with the resultant release of its engagement with the stud on the cap elevates the cap above the body and fpermits the springs 5l at the ends of the bodyto hold the arms 47 in the inclined positionshown in Figure 14. During this Aoperation shoulders 58 slide out of `engagement with the shoulders 57 and the inclined shoulders 56 `ride over the inclined surfaces 55, thereby permitting the-cap 27 to shift laterally so `that the stud thereon will be in substantially coaxial relation to the handle.

In all forms of the invention here illustrated it will be `observed that I have provided a construction wherein the handle, body and cap are inseparable though relatively movable. Clearly, there is no difficulty to be'encountered in'effecting cleansing as this may be readily done when the elements 'are partially disconnected by reverse rotation of the handle. In `all forms it will be noted that ample provision has been made to maintain both the cap and the blade'awayfrom the body so that the edge of the blade will not contact with the latter and be-dulled as the result when the cap is swung to open position. The device is bound to `be :convenient inasmuch as there is no need for handlinga plurality'of pieces as is necessary in theordinary type Iof Gillette razor and consequently no likelihood of dropping or misplacing any of them. From a sanitary standpoint there cannot possibly be any objection as all the parts of any form of the device may be readily cleaned by the action of .a stream of water issuing from a faucet.

From the foregoing description and a study of the drawings it will be apparent that I have provided a safety razor closely resembling the well known and popular type referred to and which not-only possesses all the advantageous 12.0.

features thereof Abut which possesses the additional characteristics which will render it still more convenient'to use without in any way adding to the complexity of the structure or the cost of` manufacture. It is thought that the construction, operation and advantages should be readily apparent to one skilled inthe art without further explanation.

While I have .shown and described the preferred embodiments of the-invention, yit should be understood that the disclosure is merely an exemplifcation of the principles involved asthe right is reserved tov make all such changes in the details of construction as will widen the field of utility and increase the adaptability of the device provided such changes constitute no departure from the spirit of the invention or the scope of the claims hereunto appended.

A razor comprising cap and body members adapted to have a blade interposed therebetween, the body having oppositely disposed guards on its longitudinal edges, means embodying pivotal elements permanently and movably connecting a longitudinal edge of the cap with the adjacent edge of the body and enabling the members to have relative swinging movement, screw means embodying engageable and disengageable screw elements for moving the members into clamped or released relation to the interposed blade and establishing an axis of relative rotation of the members, the said axis being established by a rectilinear shifting of said pivotal elements accompanying the relative moving of the members into released relation to the blade and when so established lying in position parallel to an adjacent longitudinal edge of one member and in temporary spaced parallel relation to the corresponding longitudinal edge of the other member, and spring means stabilizing the axis in said spaced parallel relation during all stages of the relative swinging movement, whereby the edge oi the blade is protected from damaging contact with the moving parts and whereby the elements of the screw means will be disposed in axial alinernent upon return thereof to operative engagement.

35. A razor comprising cap and body members adapted to have a blade interposed therebetween with an edge of the blade protruding from between two corresponding edges of the members, the body having oppositely disposed longitudinal guards, means permanently and movably connecting the members by journal and bearimT elements and enabling them to have relative swinging movement about an axis neighboring corresponding edges of said members, screw means for producing relative rectilinear movement of said members into clamped or released relation to the interposed blade, said axis being temporarily established by rectilinear movement of said elements in spaced relation to one of said members during releasing operation 01"' said screw means, and spring means stabilizing said axis in said spaced relation during all swinging movements of the members.
