Application filed October 8,1906. Serial No. 337,978.

To all whom it may con/ eerie.-

Be it knownthet I, WiLLIAM C. Hermes DINGER, a resident of Louisville, in the county of Jefferson and State of Kentucky,

' -heve invented certain new and useful Imrovements in Safety-Razors and I dohere- Ey declare the following-to be at full, clear,

and exact description of the invention, such as will enable others skilled in the art to c which it epperteins to make and use the some.

My invention relates to improvements in soi'etydazors, the object oi the invention being to provide improved means for quickly, accurately, and securely locking the parts together with the blade or blades in place.

A. further object is to provide an improved blade for safetywezors.

Hcretoforc sslety-rezors have been uni- 2c formly secured in assembled formation by means of scrcvwtl'lreaded parts, which may be adjusted too tightly to the injury of the razor or may be left too loose and tail to work properly.

My improved connecting or locking mcch enisln lcsv'es nothing; to the judgment of the user and 'elt sys insures it perfect assemblage of ports and is strong and lura'ible in use.

With these objects in View the invention consists in certain novel features of construc tion. and combinations one arrangements of parts, as will he more lull lieroinefter do scribed, and pointed out in claims.

In the ecconlpenyinsr drawings, Figure l is 55 s. View in ele ation illustrating; my improve-- blades removed.

ig. 6 is eview of one of 5 represents the guard, which is made flat and provided with downwardly-inclined guard-fingers at opposite side edges. The f, guard is provided at each end with two upturned flanges 6, which are spaced apart to form central notches or recesses 6 at respective ends of the guard, and sold upturned flanges ere beyeled or inclined towerd the side edges of the guard.

' The guard secured to the by means of screws 7, the latter screwed into threaded openings in the slotted portion of the cross-head and serving as stops to limit the movement of the locking-slide 4. The upper ends of the screws above guard 5 are made with enlarged heads, which, together with a central collar 8 on the go ird, serve to guide the blades 18 to proper position. This central collar registers with openings in the ggxmrrl, cross-heud 3, end guide-block 2 to receive a centrel stud ,10 on the curved backing l 1, the collar is preferably made with internal guide pins 01' lu s 1.2 to enter longitu- (linal grooves 13 in stu 10 toinsure the back ing hein properly placed. also met e with a slot 14- to receive the lock lug-slide 4 when the letter is slid to locking position, as will now be explained.

'lhelocking-slide 4 comprises a metal plate and crosshend 3 end is notched at its upper corners, providing shoulders 15 to strike screws 7 and limit the movement of the slide. The olote also made with a. slot 16 extend ing rem its upper edge downward to near its lower end then extending longitudinally of, the plate, providing a lockin 'tongue 5.7 to enter the slot 14 in stud 10. T e lower edge of this tongue l7 is made on an incline to exert cum action on the stud 10 to draw the hacking to its proper place to firml clamp the blades 18 in position. When the slide is moved to one extreme position, the slot ill will permit the stud 10 to be readily removed or inserted, and when. the slide is moved to its other extreme position the Each blade comprises a, strip of cross-head 3 The stud 10 is tongue 1ft" will be in the is of stud 10,

mounted to slide in the slot in guide-block 2 thin steel having a sharp longitudinal cutting edge, the opposite longitudinal edge being provided with three notches 19 to receive the screws 7 and collar 8, and the blade is notched at its ends to fit between the up turned ends 6 of thc'guard and provide lugs 20 to roject out through the notches 6. These ugs afford an easy and safe finger-hold to handle the blade, and they, together with the notches 19 against the screws 7 and collar 8, insure the blades being properly placed on the guard, as it is quite impossible to place the blades in any other position.

When the blades are in position, the backing-stud 10 is inserted through collar 8into guide-block 2, and the locking-slide is moved longitudinally to lock the arts, as above explained, and the blades will be tilted by the edge of the curved backing so as to lie fiat against the guard-fingers in correct position for shaving with perfect ssfiety. A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence Ldo not re strict myself to the precise details set forth,

but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is-

1. In a razor, the combination with a uard and a backing, oi a stud on the backing to enter an opening in the guard said stud having a slot therein, and a locking; device constructed to pass through said slot and lock the parts together.

2. In a razor, the combination. with a guard and a backing, of a stud onthe backmg to enter an opening in the guard said stud having a transverse slot between its ends,

and a sliding locking plate or bar constructed to pass through the transverse slot in the stud and lock the parts together. 3. In a razor, the combination with a handie having a slot therein, a guard secured thereon, a backin and a slotted-stud on the backing to enter the handle, of a sliding locking-plate in'the slotted handle and a tongue on the locking-plate to enter the slotted stud and lock the parts together. a

e, In a razor, the combination with a slotted guide-block, and a guard. securedv thereon and having opening alining with an opening in the guide-block, of a backing,

a slotted stud thereon to entcrthe openings in the guard and guide-block,'a' slide in the slotted guide-block, and a tongue on said slide to enter the slotted stud and secure the parts together.

5. in a razor, the combination with a handle, a slotted guide-block fixed to one end of thc'handle, a cross-head on the block, and 3.

scenes guard secured to the cross-head and having a central opening alining with openings in the cross-head and guideblock, of a backing, a central stud on the backing to enter the openings in the guard, cross-head and guide- 6.
