formed at its broader forward edge with the well known type of razor guard 2. Projecting from the lower surface of the head I, is a tubular member having a substantially spherical portion 4 at its lower end. The tubular portion 4 seats on theupperhollow` end 510i aihandle 6 having a screw threaded portion 'I receiving one vend of an internally threadedsleeve 8. The upper end of the `sleeve 8 is formed as at `.Il to engage the spherical portion 4 .and thus there is provided aball and socket type of universal joint between the head I and the handle and by tightening the sleeve 8I suiiicient friction may be provided Vto hold the head in'any angular position desired. `Various angularipositions of the head relative` to the' and maybe readily observed upon reierence to Figs. 1,v 3 and 4 of the drawing and in this manner the headmay be angularly adjusted to suit the'wishes 'of any user. o i i .Extending upwardly from the top surface oi the head I are a pairof spaced ears I0, the-latter being positionedlrenlote from the forward guide edgezZ. A pivot pin `II `is supported in the ears I and mounted on the pivot pin is a clamping plate I2. Thustheclamping plate I2 is mounted topivotvrelative to the head IV and a spring' I3 is sleeved on the pivot pin with one endengaging the head I'and its other end-engaging the clamp ing plate 'I2 and normally urging the latter to pivot towards the positions ishown in Figs. 2, and 8; i i i l `Secured tothe under face of the clamping plate I2 is a grooved stud I4^ so'positioned that it is in alignment withv and projects slightly into theltubular member 3 when the clamping plate is positioned` as shown in Fig. 7. Asis common in safety razors with removable blades there are also provided pin's `I5 on the clamping plate that serve in the Well known manner in indexing the blade relativevto the supporting head.` The blade is designated by the numeral IE and althoughit is not shown in the drawing it will be understood that the pins I5 extend through apertures in the blade and head I.` i

Slidablyl disposed in the spherical portion Il is ablock I'I having a pair of pivotally mounted grasping ngers I8 mounted on the top thereof, the latter being formed with levers I9 extending radially relative to the block I'I. The grasping lingers I8 are disposed within the tubular member 3 and the latter is formed with two pairs of abutments, there being a pair of abutments 20 and 2| adjacent to each finger I8. The abutr'nents 20 and 2I are spaced above the levers I9 on the respective ngers I8 andare spaced one from the other; i

Slidably mounted in the handle 6 is a plunger handle have been shownV position. At this 22 having a finger piece 23 extending through a plug nut 24 received in the lower end of the handle 6. A coiled spring is sleeved around the plunger 22 and normally urges the latter towards the position illustrated in Figs. 6 and '7. The upper end of the plunger 22 is connected to the slidable block I1 by a universal joint 26.

In describing the operation reference Will be' had more particularly to Fig. 6. Let itbe assumed that manual pressure is placed on the linger piece 23 tending to compress'thevspring 25 and move the plunger 22 upwardly relative to the handle 6. Such movement ofthe-plunger imparts sliding motion to the block I1 and the latter carriesthe ngers I8 upwardly so that the levers |9 strike the abutments 2|. Continued upward movement of the block I1 with the levers |9 in engagement with the abutments 2| causes pivotal movement of the fingers' I8 so that the latter spread apart at their upper ends and are thus moved out of their grasping engagement with the grooves in the stud I4. In this manner the clamping plate is released and the energy stored in the spring I3 urges the clamping plate to its open time the blade I6 may be lifted ofi the head I or it may be dropped ofi by tilting the handle.

In order to replace the blade and to hold it in position for use it is again placed on top of the head I. The nger piece is again pressed manually to spread the grasping fingers I8 and the clamping plate is then moved towards its clamping position by manual pressure. As the clamping plate is moved so that the stud I4 is again disposed projecting slightly into the tubular member 3 the manual pressure is gradually relieved from the linger piece 23 and the spring 25 causes the plunger 22 and sliding block I1 to move downwardly. As the fingers I8 are carried downwardly the levers I9 are moved out of engagement with the abutments 2| and at the same time the fingers I8 are moved into engagement with the abutments 20, the latter abutments causing inward pivotal movement of the ngers as they move downwardly. The inward pivotal movement of the fingers I8 causes the latter to engage the grooves in the stud I4 and the plunger 22 is thus connected to the clamping plate I2 so that the energy stored in the spring 25 tends to maintain the clamping plate in its blade retaining position.

In the modified form shown in Figs. 9 and 10 to which reference will now be had there is shown a razor comprising a handle having a blade receiving head 3| on` the top thereof. In the handle is provided a plunger 32 which is urged downwardly by a spring 33, the plunger having a finger piece 34 so that it may be moved manually. A blade 35 is received on the head 3| and a retainer plate 36, having indexing pins 31, has a grooved stud 38 extending through an aperture in the blade. Grasping fingers 39 carried on the upper end of the plunger 32 engage in the grooves of the stud and so grasp the same that thepressure of the spring 33 on the plunger holds the retainer plate 36 in its blade retaining position. Adjacent to each finger 39 are a pair of spaced abutments 40 and 4| and each finger has an integral lever portion 42.

The operation of the ngers 39 in holding the plate 36 in its blade retaining position is identical to that described above in reference to the first mentioned embodiment and accordingly it ben comes obvious that the present blade retaining means is applicable to various types of razors having stationary blade supporting heads.

Although specific embodiments of the present invention have been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.

What I claim is:-

1.
