CARL C. KING, OF WASHINGTON, DISTRICT OF COLUMBIA.

To all whom it may concern:

Be it known that I, CARL C. KING, a citi zen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Improvement in "Safety-Razors, of which the following is a specification.

My invention relates to improvements in safety razors, and more particularly to the character of the handle and guard plates and the shape and position of these members with relation to one another, by which improvements I provide for greater casein theme of the razor 1n shavlng and for a more desirable safety razor generally.

Another object ofthe invention 1s to pro-.-

vide quick and simple means for attaching and detaching the blade and cap plate.

A further object of the invention is to provide a blade and a cap plate so shaped that theywill be highly convenient to grasp with the fingers in attaching them to the guard plate or in handling them with other purposes, and thereby also effecting. a sav-- ing of material in their manufacture.

With these objects in view my invention consists in the novel features of construction, material, andcomb1nat1on of parts hereinafter described and pointed out in the 85 the handle turned to its longitudinal posi- 3 isan end view of the construction shown in Fig. 1, with the-handle, which is pivoted 1 I the pivoted or swiveled finger rest to the end of the-handle. 'Fig. 4 is aside view of plates.

Fig. 1. Fig. 9 is a detail perspective view of the guard plate, blade and cap plate as- -the cap plate, blade and guard plate together. Fig 11 shows the shape of and the manner of cutting the blades from sheet I metal so as to economize in the use of metal. v r

Llke reference numerals refer to similar parts throughout the several views.

m In carrying out-my invention I employ a double-edged guard 6, with guard teeth 12; and a double edged blade 7, and a double-edged cap plate 3, which guard,

blade and cap are adapted to be attached together as shown in Figs. 1, 2, 3, Sand 9,

by headed pins, 10, pivoted at 9 to the guardplate 6, movable in a plane at right angles to the plane of the guard plate, and held in normal position by the spring 8, as shown in the sectional view" Fig. 8. While -I have shown the

pivoted pins

10, 10, with-substantially round heads, it is obvious that they maybe made with a notch, a shoulder, or flange on one or more sides, or may be made inthe shape of a latch, and I do not desire to limitjmyself' to the exact construction shown. It is also apparent that a cap plate is not absolutely essential in t e con.- struction of my razor, as the .head (1 pins gage and clamp: or hold the blade alone in ;proper position with relation to the guard without thef use of a cap, and-I desire that such arrangement be considered as within. Y

the scope of my invention.

,The headed pins 10' are provided with pivots .9, which fit into the bearings in the guard plate 6, and the said pins have their 'underi ends so shaped that-the spring 8 on the underside of the guard plate 6 will.

bear against the portion 17 of the said headed pins and cause them to-press normally against the cap plate and blade when g ition, the headed portions of the-pins fitting snugly into the recesses inthe ends of the cap plate 3, as shown in Figs. 8 and 9, so as to lock or secure these parts to the guard plate.

When it is desired to detach the capplate and blade from the guard plate, it maybequickly and easily done by pressing the thumb or finger against one end of the cap plate and blade, which may be so constructed as to project slightly beyond the end of the guard plate, when the headed pin at the opposite end of the guard platewill be turned on the pivot 9 sufliciently far to allow the ends of the cap plate and blade so pressed and moved longitudinally on the guard plate to pass the head of the other pivoted pin with but-slight .resistance. In

-. attaching the blade and cap plate to the heads of .thepins,

the parts together in a foot20, so as guard plate, but little longitudinal pressure or sliding movement of the cap and blade is necessary, as the headed pins are so constructed that the recesses in the end of the cap plate and blade will press the heads of the pivoted pins, 10, 10, backward and al- A very important part of my. invention is the shape and character of the handle which I- provide, as shown in,Figs. l, 2 and. 3. This handle is formed with a body portion the upper end of which is pro vided with a shank or neck 19, terminating to provide for attaching the guard plate to the handle at an acute angle to the general direction of the body thereof, and, while-I claim as within the scope of my invention the construction of a razor with the handle integral with the guard plate or rigidly secured thereto at an angle of less .than ninety degrees to the Figs.

generallongitudi-nal direction of theplane of the blade and guard plates as shown'in Fig. 2, I preferably construct my razor with the handle pivoted at 2, so that it may, at will, be turned to the position shown in' l and ,2, or to the position shown in Fig. 3; always, as will be seen, maintaining an acute angle of substantially the sa 'e de- 9 gree with respect to the plane of the lade and guard plate. This construction of the handle in combination with a double-edged guard plate and doubled-edged blade, and v .with 'a finger rest on the end of the handle, as shown is a very great .015, thus suiting the improvement, as it provides a razor .handle of such shape as will allow the user of the razor in either adjustment of the handle to at all times see the point of contact of the blade and guard with the skin of the face; the hand grasping the handle being always at such an angle with respect to the blade of the razor as not to interfere with the view of the person using the razor. This construction of the handle also admits of the use of the razor with the handle extending in the longitudinal direction of "the blade and guard and in the transverse direction thereperson accustomed to the use of a razor of e ther type. The shape of the handle in either adjustment is such as'to facilitate the handling of the razor with that .sliding stroke in shaving which is considered by many persons as highly desirable; particularly is this true when the handle is adjusted to the position shown in Figs. 1 and 2, and I find that, even without a guard plate, a double edged blade attached to the end of a handle at an oblique an le to a line parallel to the cutting edges of t e blade may be used with unusual facility on either side of'the' face with either hand by one who has had no previous experience in the use of such a razor, and I consider this feature a very important part of my invention.

To provide for locln'ng the handle in either of the positions indicated in the drawing (Figs 1, 2 and 3), shown in Figs. 4 and 5, whichis attached to the foot end of the handle, 20, next to the I use a spring 5,

spring member 8 on the guard plate. This spring 5 has a lug or pin 13 adapted to fit into one of the holes or indentures 14 in the spring member 8, and thus lock the handle in the osition desired. The spring, as is shown, libs a finger piece or portion which. is adapted to extend along the neck or shank 19 0t the'handle, which finger piece is. pressed to bend the spring and lift the head or lu 13 out of the hole or indenture 14 in t e spring member 8 when it is desired to turn the handle to a difl'erent position. It is obvious that othensimple means ofproviding a spring vto lock the handle may be used and I do not desire to limit myself to the. exact construction shown.

. The blade 7 I construct with saddleshaped recesses at its ends and the blades so cut as to secure a material uantity of metal required in then manuacture. Theends, it will'be'noted in Figs.

7 andll, are shaped so that the longitudinal 1 5 portions of the adjacent edges of the blades'extend up into the recesses in the central blades in cutting them from sheet metal. This also provides a venient to handle, as the saddleor bellshaped recesses in theends of the blades are saving in the blade which is most con-.

will rotate.

rest so that it will rotate, the angle of the i very convenient in grasping the blades by their ends with the thumb and finger. It will also be noted that I provide a cap and a guard similarly constructed at their ends for convenience in handling- For convenience in grasping the razor, I provide the end of the handle with a finger rest, as shown in Figs. 1, 2 and 3, and I preferably connect the finger rest with the handle by a collar 11, fitting over an annular flange or shoulder 15, and attached to the portion 16 of the finger rest, so that the finger rest By thus swiveling the finger fingers in grasping the handle may be changed and the finger rest will readily conform to the position to agree with the direction of the fingers, thus greatly facilitating the handling of the razor in shaving. This swiveled finger rest I have claimed in my prior application filed May 26, 1909, Serial Number 498,490, but I desire to claim in this application the manner of connecting the body of thehan-dle and the finger rest with a collar as shown in Figs. 1, 2 and 3, and the providing of anti-friction roller or ball bear- 1ngs 18 at said pivotal connection as shown 'in Fig. 2. The said anti-friction bearings are provided by forming a slot or groove in the end of the body portion of the handle 1, and a corresponding slot or groove in the head of the finger rest 16, to act as channels or bearings for the balls or rollers.

What I claim as new and desire to secure by Letters Patent is:

1. A safety razor having a guard plate and a cap plate, one of-said plates having spring-actuated looking pins pivoted thereto to swing about said pivots in a plane at right angles to the plane of said plate, and the other plate having recesses adapted to engage the distal ends of said pins to hold the parts together.

2. Ina safety razor, a guard plate having combined blade-positioning and blade-holding pins at its ends for engaging the ends of a blade, one of said pins being pivoted to said guard plate with the axis of said pivot lying transversely thereof, and the pin movable in a plane at right angles to the plane of said guard plate, and a handle secured to said guard plate -at a fixed oblique angle to the plane ofsaid guard plate.

3. In a safety razor, a holder comprising a cap plate having recessed ends, a guard platehaving a pivoted locking pin at one end thereof formed to engage the cap plate at one of its ends and a spring actuating said locking pin, and a pin at the opposite end of said guard plate formed to engage the opposite end of the cap plate to hold the .parts together.

4. In a safety razor, a holder comprising a guard plate and a cap plate, one of said plates having headed blade positioning pins, one of said pins being hinged to swing in a plane at right angles to said plate, and the other plate having means engaging the headed ends of said pins to hold the parts together.

5. In a safety razor, a guard plate and a cap plate, one of said plates having a swinging latch mounted thereon movable in a plane at right angles to the plane of said plate and engaging a recess in the other of said plates to hold the guard and cap plates together.

6. In a razor, the combination with blade holding means, of a handle comprising a body portion having a flange, a finger rest having a threaded end, and an internally threaded collar adapted to fit over said flange and screw on to the threaded end of said finger rest.

7 In a safety razor, a holder comprising a blade-guard member provided with bladepositioning, blade-holdlng pins, one of said pins being pivoted to swing in a plane at right angles to the plane of the blade-guard, and a spring co-acting with said pins to aid in swinging and holding them.

8. In a safety razor, a double edged guard plate carrying a pivoted pin at either end thereof midway between the longitudinal edges of the guard plate, a spring adapted to bear upon said pins to actuate same, a blade, a cap plate having its ends formed to engage the free ends of said pins to lock the parts together, and a handle attached to said guard plate and extending at an acute angle to the central longitudinal line of the guard plate.

9. In a safety razor, the combination with blade holding means, of a handle comprising a body portion and an end portion, the body portion having a foot on one end carrying means for attaching it to the blade holder, one of said ortions having a fiange and the other portion a threaded end, and a threaded collar fitting over said-flanged portion and screwing on to the threaded end of the other portion.

10. In a safety razor, the combination with a blade holder having a threaded stud, of a handle having a body portion with a neck on one end thereof, terminating in a foot at an acute angle to the axis of the body, and a threaded thumb-nut rotatably mounted on said foot for engaging the stud of the blade holder to attach the handle to the holder.
