The handle 2 is cut out in its tending therefrom the pin that is operable upper face as at 5, for a purpose to be preswithin a transverse recess 21, formed in the ently described. Furthermore, the forward bottom face oiithe inner end portion of the end portion of the handle 2 is enlarged, as shank-9 and this feature is clearly show n in Figures 2- and 3. 'A-retractile-1 coil-spring 22 '96 is arranged between the opposed cut out faces of the handle and the housing 10. The rear end of this spring is secured in this rear end portion of the handle, while the forward end of the retractile coil spring is connected to the eye bolt 23, that is driven into the rear end of the shank 9.

Normally, the parts are arranged as shown in the drawings, and the lever 17 is held outwardly of the adjacent side of the handle of the hair clipper. By pressing inwardly on the lever. 17,, saidlever will swingonits pivot 19 to causetlle pin 2O1that is in engagement with the recess 21 to force the upper blade 7 forwardly along the upperface of the bottom blade 3 against the-tension of the coil spring 22, whereby the cutting teeth i and 8 will cooperate to out the hair.

lsothe construction of my hair clipper is such as to permit the parts to be readily and easily assembled or disassembled for cleaning purposes whenever necessary.

While I'have shown the preferred embodiment of my invention, it is to be understood that various changes inthe size, shape andarrangement ofpart's may be resorted to, without departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention, What I claim'asnewis:

through the enlarged head of the lever and through the lower handle portion; and an upstanding pin on the inner exterinity of the enlarged head of the lever for operative engagement in the transverse slot of the upper blade shank; and a contracting spring having one end stretched between the eye on the extremity of the upper blade shank at a point near the rear portion within the casing formedby said cover plate and the handle portion of the lower blade.

In testimony whereof, signature.
