The present invention is directed to improvements in Sharpeners for hair clipper blades.

The primary object of the invention is to provide a device of this character so constructed that clipper blades of various sizes may be effectively sharpened.

Another object of the invention is to provide a. device of this kind constructed in such manner that the blade will be held yieldably engaged with the sharpening stone during reciprocation of the blade.

Another object of the invention is to provide a device of this kind wherein provision is made for ejecting the sharpened blade after each sharpening operation.

YVith these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure l is a side elevation of the device.

Figure 2 is a .sectional View on the line 2-2 of Figure 3.

Figure 3 is a longitudinal sectional view through the device.

Figure 4 is a sectional view on the line l l of Figure 3. c

Figure 5 is a perspective view of one of the blade holding plates.

Referring to the drawings, 1 designates a base having corner posts 2 rising therefrom which support the top 3. Mounted on the base 1 are spaced strips 4 between the ends of which are secured blocks 5 which serve to prevent endwise movement of the sharpening stone 6. Obviously, the strips l will prevent lateral movement of the stone. One of the strips is provided with a recess 7 while the other has carried thereby spring pressed ejectorbars 8 which are slidable through the associated strips and are connected at their outer ends by a push bar 9.

A blade holding block 10 is provided and has one end recessed, as at 11, and in which is extended the inner end of the pitman 12, said pitman being pivotally connected to the pin 13 secured to the block and bridging the recess. This pitman has its outer end con- Scrial No. 385,815.

nected with the crank i l of a shaft 15, said shaft being journaled in the adjacent pair of corner posts 2.

he block 10 is slidablo between the guide strips 4; and extending from the sides of said block are lugs 16, the purpose of which will be later explained. I I

Sjupportcd by the top 3 are hangers 17 in which the ends of the shaft 18 are journaled sa1d shaft having a clamp 19 connected there to much is clamped to the rod 2O. The shaft alndl 12nd passed through openings q ipipeotively, n tne plates 23, the .na n0 obviously S-PIVlll" to interlock the shaft 18 and plates 23.

The plates 23 have their lower ends formed with recesses 24 to accommodate the lugs 16, there being elastic straps 25 secured I -"1 t) said plates 101 yieidably engaging the lugs, I

as clearly shown in Figure 1 of the drawiiws.

Interposed between the top 3 and blo zk 10 are COll springs 26, arranged in pairs said springs normally serving to urge the block 10 downwardly, the purpose of which will appear later.

The under surface of the block 10 is provlded with a seat 27 for receiving a blade holding plate 28. The plate 28, as shown in i lgure 5, is of a conventional. form the sock thereof serving, clipper blade 30. The socket of the plate may vary in size, in order that blades of various sizes may be conveniently olaced therein for sharpening. L

lVhen a plate 28 is mounted in the seat 27 the blade 30 in the socket 29 will contact with the stone 6, and upon rotation of the shaft 15 the pitman 12 will operate to reclprocate the block 10 to move said block backwardly and forwardly upon the stone 6. In thls manner, the blade can be quickly sharpened, the construciton being such that a barber can, 111 a very short time, sharpen a number of blades.

After a blade is sharpened, the push bar 9 1s manlpulated to shde the ejector bars in- L wardly LO engage the plate 28 and force the same laterally through the recess 7.

D ur1ng reciprocation of the block 10, the springs 26 and straps 25 will urge the block as usual, to receive the downwardly in order that the blade 30 will be yieldably held in contact with the surface of the sharpening stone 6.

The shaft 15 may be rotated through the medium of a belt driven pulley 31 or, if preferred, a crank handle may be applied to the shaft.

The springs 26 and straps 25 will permit the block 10 to be elevated slightly in order that the blade holding plate can be conveniently inserted in the socket 27.

From the foregoing it is thought that the operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion, materials, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What is claimed is:

1. A blade sharpener including a sharpening stone, a block thereon recessed in its lower face, guide strips at the sides of the stone and block, one of the strips having a recess, an ejector on the other strip, a blade holder in the recess of the block and displaceable therefrom by the said ejector, means for reciprocating the block, and yieldable means pressing the block on the stone and normally retaining the blade holder in place.

2. A blade sharpener including a sharpening stone, a block resting on the stone and having a recess in its lower face, a blade holder removably fitted in the recess of the block, means for reciprocating the block, plates at the sides of the block having notches in their lower ends, a shaft above the block pivotally supporting the plates, a rod passing through the plates below the shaft and clamped to the shaft, projections on the sides of the block, and elastic elements carried by the lower ends of the pivoted plates and spanning the notches therein to bear upon the projections on the block to yieldably hold the latter on the sharpening stone.

3. A blade sharpener comprising a base, a sharpening stone mounted on the base, a block having a seat in its lower side and resting on the stone, a blade-holder removably
