10 claims. (01. -87) Our invention relates to razors and more particularly to those of safety type including a blade holder and'a handle'arranged perpendicu-. larly one to the other, whereby the edge of the blade may efiect contact with the usersfa'ce over a transverse area when drawn over the face. P

In shaving with'a' straight edge razor, or with one of 1 ordinary safety type, it is difficult to effect an even, smooth contact of the blade with the 7 face. throughout the entire'length of the blade, because of the unyielding and'rigid connection between the blade and handle,-:.whereas rotary movement of the blade or in the connection be tween blade and handle, would permit the automatic adaptation of the blade to the facialcontours; desirable for smooth and comfortable shaving. a I V ,J r 1 V It is, therefore, the object of our invention to provide a razor having such advantages.

It is also anobject of our .invention to provide a razor embodying such improvements, wherein the working parts are inclosed to protect the same from water, soap or foreign matter that might tend to prevent smooth operation "or rustingzof the parts.

Our invention can be adapted foripractically" all types of safety razors, but in-accoinplishing the above and other objects, we haveprovidedimin assembled condition with part of the handle being broken awaytoillustrate theautomatically adjustable connection in-the handle member;

Referring more in detail to the drawing:

I designates the bpdy portion of a razorhan-i dle one end of whichis reduced, as shown at 2 (Fig. 2), to form-awprojecting, slightly less than semicireular,-segmental boss 3. The body portion of the handle is centrally bored to receive a tie rod 4 of a blade carrying unit, suflicient clearance being provided to allowrotation of the tie rod in the bore.

:operating counter part-thereto when fitted onto the tie rod 4 by means of the central bore 6;. The :bar 5 maybe fixed to the tie-rod 4by a" pin 9 or similar retaining means inserted through a hole Him the tie rod and hole I tin-the bar. 10

,A space l2, as shown in Fig. 4, is effected by the difierence -in shape between the combined counter bosses 3 and 8 and a full circular projection to allow a limited free rotary movement of the bar 5- and'tie rod-4; this rotarymoyement 15 constituting a degree of play between the blade; carrying unit and handle body portion of the razor. j v v Should it be desired to use the razor without; rotary movementbetween the blade carrying nit and the handle, a locking key I 3 is seated in a groove l4 of the body portion landwhich, when projected outwardly, willfill the space I2, there-- bypreventing rotary movement of the bar 5 and rodd. e 25 A suitablespring I5, later to bemore particularly mentioned, is provided on the locking key I3 and h q qrliinena s the lade ca r i unit are then incased in a cover [6, one .endxof' which aligns with the outer end of the bar 5 Aslot I1 in the sleeve, directly over and aligne ing with the locking key l3 and groove M, i s. vere b as ita s ide i in ace on: the surface of the handle cover by a screw -19 extending through holes in the slide l8, spring I5 and locking key l3 respectively. Thus by m n ulat n the Slide i h? l c n .ke zma be .moved into and out ofthe space 'to respec- I tively prevent and providelimitedrotary movementof the blade carrying unit, and reason "-v of the spring 15, the slidelB willbe held insuch cover I 6, thereby providingtheshankwitman v automatically, adjustable connection on .;the 'ltie rod in corresponding relation to the bait." v The outer portion ofthe shank is provided with a male adapter 25 screwed into a head 26 of the shank 20 and adapted to fit the female screw of a blade carrier 21. To use the automatically adjustable handle with blade carriers having male adapters, the adapter 25 need only be removed and the male adapter of the blade carrier screwed into the female of head 26.

Assuming the parts to be constructed and assembled as described, the operation thereof is as follows:

The assembled handle comprising the shank 20, the tie rod 4, the bar 5, body portion I, block mechanism and cover, is screwed into a blade carrier by means of the adapter and the razor is ready for use.

For general use, rotary movement between the handle and the blade carrying unit is desirable, but in trimming a moustache a rigid and unyielding razor is necessary By moving the slide l8 away from the blade carrier, the key l3 may be moved to enter the space 12 and prevent rotary movement'of the bar 5, as well as the shank 2!) and blade carrier, thereby preventing rotary movement of the razor and producing a rigid and unyielding razor.

For shaving other parts of the face, and the upper lip when the user is clean shaven, a limited amount of rotary movement between blade and handle 'is'desirable and is effected by moving the slide l8 toward the blade carrier. This action removes the key from the space l2'and allows movement of the bar 5, tie rod 4, shank 20 and consequently the razor blade carrier, so'that the blade will yield to and follow the natural contours of the face to produce a smoother shave than with ordinary devices.

The working parts of the device are kept dry and clean due to the extension of the cover I6 from the end of the bar 5 to well up on the shank 20, thereby preventing clogging, rust and unnecessary wear.

In sharpening some razors of the self-strapping type, it is evident that an angled or cross'stroke of the blade on the strop will more readily even the blade and eiTect a keener and sharper edge, and the razor is adjusted for limited rotary movement so that the blade carrier will be drawn across the strop at an angle when moved in one direction and at an opposed angle when moved in the opposite direction, to produce a finer edge by the cross stroke.

While we have described the razor as being used only on the face, it is evident that women can use the razor for shaving their legs and under the arms, it being advantageous to use a razor embodying our invention for that purpose.

What we claim and desire to secure by Letters Patent is;

1. A razor including a cylindrical handle bar, a tie rod rotatable in and projecting from the ends of the bar, a stop member keyed to one end of the rod, and a blade carrier keyed to the opposite end of the rod.
