STEPHEN V. DILLON, O'F BUTLER, PENNSYLVANIA, ASSIGNOR TO THE DILLON SAFETY RAZOR 00., A CORPORATION OF DELAWARE,

SAFETY-RAZOR.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed January 30, 1911. Serial No. 605,571.

citizen of the United States, residing at.

Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors;

and I do 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.

This invention relates to improvements in safety razors.

One object of the invention is to provide a safety razor having an improved construction and arrangement of blade adjusting mechanism whereby the blade may be adjusted for shaving more or less closely.

Another object is to provide a bladeadjusting mechanism which may be readily swung to an out-of-the-way position to permit the stropping of the blade.

In the accompanying drawings Figure 1 is a side view of a safety razor constructed in accordance with my invention. Fig. 2 is a bottom plan view thereof; and, Fig. 3 is an end view. Fig. 4 is a central vertical longitudinal section. Fig. 5 is a detail horizontal section on the line 55 of Fig. 1. Fig. 6 is a detail perspective view of the bolt for the blade adjusting mechanism.

Referring more particularly to the drawings 1 dentotes the blade holding frame of the razor, said frame comprising side plates 2 connected together at their rear edges by a transversely disposed handle attaching plate 3 and having on their front edges forwardly extending bearing lugs 4 The lower ends of the side plates 2 are connected together by an integral guard plate 5 having on its lower edge a series of rearwardly curved comb teeth 6.'

To the rear plate 3 is secured a rearwardly projecting handle 7 which is preferably in the form of a cylindrical tube and is provided on a portion of its length with a checkered surface 8 whereby a firm grip may be obtained thereon. The inner end of the handle has formed thereon attaching lugs 9 which are riveted or otherwise secured to the rear plate 3 of the frame 1. Revolubly mounted within the bearing lugs 4 of the side plates of the frame is a blade supporting shaft 10, on which is fixedly secured a plate clamping member 11 which may be of any suitable construction to receive the inner portion of the blade 12 whereby the latter is firmly held in place. In the blade 12 is formed a centrally disposed aperture 13, the purpose of which-will be hereinafter described. I

Revolubly mounted in the bearing lugs 24 of the side plates 2, immediately in the rear of the shaft 10, is a strop engaging,

roller 14:. Revolubly mounted in the upper and lower portion of the side plates 2 are strop engaging rollers 15 and 16. When the strop is engaged with the razor for the purpose of stropping the blade, the strop is inserted between the rollers 15 and 16 and,

the roller lt said rollers thus frictionally engaging the opposite sides of the strop as indicated in dotted lines in Fig. 1 of the drawings. When thus engaged the razor frame is reciprocated back and forth whereby the frictional engagement of the strop with the rollers will revolve the same first in one direction and then the other. On one end of the shaft 10 and the pintle of the roller 14: are fixedly mounted intermeshing spur gears 17 and 18 by means of which the movement of the roller 14: when engaged with the strop, will be imparted to the shaft 10 to swing the blade clamping member 11 and the blade 12 back and forth, thus en: gaging first one side and then the other of the blade with the strop.

In order to provide for the adjustment of the blade and cause the same to shave more or less closely, I providea blade adjusting mechanism'comprising a pair of curved arms 19 which are pivotally connected at their inner ends with the outer sides of the side plates 2 as clearlyshown in Fig. l of the drawings. The lower upwardly curved ends of the arms 19 are connected together by an inwardly curved, integrally formed plate 20. The lower portion of the platev 20 is preferably tapered to an edge as shown. The plate 20 is drawn into frictional engagement with the edge of the blade and said edge thereby sprung into more or less close engagement with the toothed lower end of the guard 5 by means of an adjusting bolt 21 having a loose connection with the plate 20. This connection comprises a stud 22 having on its inner end a pair of apertured lugs between which is pivotally connected the flattened outer end of the bolt as shown. The inner end of the bolt is tened to the rear side of the guard 'plate 5 by screws 28 or other suitable fastening devices. The nut 25 whenthus arrangedwill be revolublysecured to the guard plate and adapted to be turned in one direction or the other and thus screwing the bolt 21' inwardly or outwardly whereby the latter will actuate the adjusting plate 20 to drawthe edge ofthe blade into more or less'close engagement wit-h the toothed edge of the guard-plate.

When it is desired to-stropthe blade the nut 25' is turned to screw the bolt 21 entirely; out of engagement therewith, thus permittingthe blade'adjusting arms 1'9'and plate 20 to be swung upwardly and rearwardly onto the handle 8' as shown in'dotted lines inFig. 1 of the drawings in which position said blade adjusting parts will be out of the way and prevented from interfering with the operation of'the strop.

From the-foregoing description taken in connection with the accompanying drawin'gs the construction and operation of the invention will be readily understood without requiring-a more extended explanation.

Various changesin the form,proportion and the minor det-ails'of construction may be resorted to'without' departing from the principle or sacrificing any of the advantages of" the claimed invention as definedin member-into engagement with'the edge of the blade whereby the latter is sprung into copieso: this patent maybe obtained for five cents each, b'yaddre'ssing'the Commissioner of 1 mm,-

more or less close engagement with the guard. v

2. In a safety razor, a frame, a pivot-ally mounted blade holding member, a blade secured therein, a blade adjusting member adapted to hold said blade in operative engagement with said guard, said adjusting member'comprising a pair of curved arms pivotally connected attheir upper ends to said frame, a curved plate formed between the lower ends of said arms, an adjustingv bolt loosely engaged in saidplate, a revolubly mounted nut adapted to receive the threaded end of said bolt whereby the latter is actuated to 'draw' saidadj'usting plates ginto forcible engagement with the edge of jthe blade whereby the latter is sprung into lmore or less close engagement with said 3 guard.

3. In a safety razor, a frame,- a toothed guard formed thereon and having formed therein avpass'age, a blade holdingmember pivotally mounted in said frame, a blade seouredin said-holdingmember, said blade having for'medtherein an aperture, a blade adjusting member, said member comprising a pair'of curved arms pivotally connected at their-outer ends to'said frame, a curved plate formed between the lower ends of said arms, said plate being tapered toward its lower edge',;a stud arranged in saidplate, an adjusting bolthingedly connected to said stud, said bolt having a threaded inner end,

adapted to project through the passage in said guard plate, a recessed nut" attaching plate secured to the rear side of said guard plate, a nut having a revoluble engagement with said attaching plate and adapted to receive said threaded end of the bolt whereby the latter is screwed inwardly or outwardly, thus actuating-said blade adjusting member, whereby the edge of the blade is sprung into more or less close engagement with said-guard Intestimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
