SAFETY-RAZOR.
1 331,483. Specification of Letters Patent.
Application filed February 25, 1919. Serial no. 270,159.
To all whom it may concern:
Be it known that we, ARTHUR WILLIAM BUTTERF'IELD, cutler; SAMUEL Bo'rmnrmnp, cutler, and ARTHUR Nmno, electrical engineer, subjects of the Km om of Great Britain, residin respective y, at 48 Yorkshire street, 01 am, in the county of Lancaster, England; 48 Yorkshire street, Oldham, 1n the county of Lancaster, England, and 33 College road, Oldham, in the county of Lancaster, England, have invented certain new and useful Improvements in or Relating to Safet -Razors, of which the following is a speci cation.
the type in which the handle is arranged at right angles to the plane of the doubleedged blade, which atter is' clamped between a guard and backing-plate, the guard being composed of two parts with means for adjusting the two parts in relation to each other to accommodate varying widths of blade. According to the present invention, in this type of razor the adjustment is adapted to be effected by rotation of the handle. Meansare then provided for locking the parts in the adjusted condition.
Advantageously the handle carries a toothed inlon or wheel which enga es with a plura 1ty of other toothed ment which the adjustment of the is efiected. ,Such other toot members may be rotary or sliding members, and they may impart movement to the guard sections b virtue of the function of the cam slots. The guard sections may carry studs or rojections which work in elongated slots in a guard base or sup ort located transversely to the length of t e latter, and said studs may also engage within the cam slots which are dis laced by the rotary or sliding members w ich cooperate with the toothe wheel carried by the handle.
In order that this invention may be clearly understood and readilyl carried into practice, reference may be ad to the appended explanatory sheet of drawings, upon which Figure 1 illustrates partly in elevation, and partly in sectional elevation, an embodiment of the present invention.
Fig. 2 illustrates in lan the internal mechanism of the razor shown in Fig. 1.
This invention relates to safety razors, of
rs, by uard sections- Fig. 3 is an inverted sectional plan of the razor shown in Fig. 1.
Fig. 4 is a section on plane 12 of Fi 2. g. 5 is a similar view to Fi 2, i1 ustrating a modified embodiment o the present invention.
In a convenient embodiment of the present invention, a is the guard base or support which is in the nature of a shallow pan. 6, b are the guard sections, each of v which is furnished with two studs 0 which project through elongated slots at arranged transversely in the guard base. 8 is the backing-plate which is furnished with studs e passin throu h perforations in the guard base. S eeve-li e portions f encircle these perforations, and said sleeve-like portions form bearings for rotary members located within the base a, and between t e latter and the guard sections 12. In these rotary members cam slots h are provided. cam slots receive the studs or projections 0. Thus when the members 9 are rotated, the guard sections 6 are collectively displaced outwardly orinwardly. In order to provide for the collective rotation of the members 9, an intermediate rotary member '5 is provided. This rotary member is furnished with teeth which are in mesh with teeth upon the members g, said rotary members g and i being gears. The said member 71 1s suita'bly secured to the handle 1'. By rotation of the latter the guards are thus effectively adjusted. The handle 7' is ap propriately shouldered, and a plate 1: is incolgporated between the shoulder and the un erside of the base a. This plate has a key Z engaging with a key-wa in the handle 7' so that it is rotated with t e latter. The plate is in relation to aduations upon the under surface of the ass a. The degree of adjustment is thereby indicated. m is a sleeve which is screwed upon the handle 7', and
which can be tightened to lock the latter in These.
has a pointer which operates Mar the uard sections and assist in positioning the atter during their movements.
p is a plate adapted to be applied to the base in order to inclose the gear mechanism and thereby exclude foreign matter.
In order to adjust the uard sections it is only necessary to first reUease the backingplate 8, then to unlock the handle by the sleeve m, and adjustment can be efiected. The handle is then again locked, and subsequently the backing-plate s is tightened in the usual manner.
The modification illustrated by Fig. 5 differs from thatalready described in that the rotary members 9 are replaced by sliding members 9 having racks which are in mesh with the gear wheel 71 provided upon the handle. These members 9 are so incorporated within the base that they are incapable of lateral derangement and their rack portions thus remain in effective cooperation with the wheel i throughout the process of their longitudinal displacement. The members 9 are each furnished with two inclined slots 1' through Which the studs 0 provided upon the guard sections pass. These studs 0 also pass through transverse slots in the base as in the previous modifi cations so that longitudinal movement of the members 9 effects the transverse displacement of the guard sections in the desired manner.
What We claim as our invention and desire to secure by Letters Patent is 1. A safety razor, a base having transverse slots, guard sections movable toward and from each other and having studs movable in said slots; gears mounted for rotation in the base and having cam slots in which said studs of the guard sections are also engaged, a handle mounted for rotation, and a gear revolved by the handle and arranged between and in engageemnt with the ARTHUR WILLIAM BUTTERFIELD.
