rEhe slidable rod 31, Fig. 1, has thereon the horizontally extei'iding pin 1412 with which one oi the iorliied ends of the arm 11-1- engages. yhe arm 114, Fig. 6, is o? bell-crank shape and is pivoted at its angle, as at 115, to au extension 115 of the plate 1e. The other forked end 147 ott the arm 1111 engages the stem 14:8 of the gear 'rent 1li-9 which is pivotally secured by stud 150 to the cross plate 129, and is 'ovided with the teeth 151 engaging the l gear wheel 1-11. The gear segn'ient has on its converging sides plungers, 153 the plunger 152 being engageable in the dash-pot -1 and the plunger 153 being engageable in the dash-pot 155, the dash-pots being secured at their bases to the plate 11 of the foundation, and each having a hole such as 156 for escape of air. r1`he helix spring 157 is secured at one end to the pin 153 located near the upper edge of the gear segment and is secured at its lower end to an extension such as 159 located below the edge oru the table 12, the purpose o1' the spring 157 being to prevent the f segment from becoming caught or listed on its pivotal center.

1t will be noted that upon pivotal movement of the arm 11114, the gear segment 149 will be niven a rocking motion whereby a partial rotary, or side to side, motion will be imparted to the shaft 137 and razor heel clamp 133.

For sharpening shears, scissors and the like, a suitable grinding Wheel, not shown, may be substituted for the disk 117, the rest 160, 'which is pivotally movable and adliustably positionable as shown in outline, being provided for maintaining the cutting edge of the shears, not shown, in sharpening contact with the substituted grinding wheel by manually holding the back edge or the shears in contact with the raised flange 131 o1c the rest. 1n operation:

y1`he blade or the razor being clamped between the outer and inner clamping members and 70 of the razor blade holder and suitably adjusted relative to the grinding vheel 30, the motor 15 and drive wheel 16 are set in motion by operation of a suitable switch S connected to a source of supply of electricity, not shown, the carriage and razor blade being moved parallel to the anis of the grinding wheel in the direction ot' the lower a 1rows ot Figs. 1V and 2 by the crossover dog 82 engaging in the worin-groove et?. Then the dog 82 comes into Contact with the inclined or cam face 40, Fig. 3, olflhe worm-groove, the dog S2 is caused to cross over whereby the movement of the carriage and razor blade holder is reversed.

To grind the opposite side ot the razor blade the razor is removed trom the holder and clamped in position to reverse ot that shown in Figs. l and 2, the operation ot the machine being stopped for effecting ths change.

, Relative to honing the razor blade: When the dog 82 reaches the end ot the wormgroove and prior to crossing over therein by Contact with the tace 19 tor reversing the movement olf said carriage. the outer side o'lE the rip-standing side-pi ce 53 ofl the car` riage is brought into contact with the horizontally extending pin ot the slidable rod 31, and the downwardly extending pin 38 of said rod is brought into contact with the adjacent side ot the neck 105, of the' shitting arm 104, and the shitting arm is thrown over into the position shown in outline in Fig. 8, this arm being carried past its pivotal center by the spring 110.

Prior to this movement ot' the arm 103 the point 109 oit the shitting lever 108 is engaged is maintained by the shifter plate 98 in en' gagement with the clutch member 87 whereby the shaft 97 and honing dish 112 thereon are caused to rotate in one direction.

Upon shifting movement oi the arm 103 the point 109 of the shifting lever is shi'lieinto engagement with the inner end ot slot 102 and the shifter plate 99 moves clutch member 93 into engagement with ie clutch member 8S), and the shifter plate 98 moves the clutch member 90 out oit' engagement with the clutch member E37 whereby the shaft 97 and honing disk 11iu thereon are caused to rotate in direction reverse to their former rotation, this reverse movement being substantially synchronous or concurrent with reverse movement ot the razor blade carriage and holder'.

For honing, the heel of the razor adjustably yclamped in the heel clamp 1322, the edge ot the razor being properly applied bythe operator to the honingdisk 117 with reference to the direction ot rotation ot this disk. Through cooperation olf the shaitt 9'?, small gear wheel 113, large gear wheel 120, arm 122, slidable block 125 and heel clamp 185 the razor blade is given a toe to heel honing movement on the surface ot the honing disk 117 followed by a heel to toe honing movement upon reverse reciprocation of the heel clamp. Upon reverse rotation of the honing disk due to reverse rotation of the shaft 97, through cooperation of the slidable rod 31, pin 142, forked arm 1411, gear segment 1119, small gear Wheel 141, and/shaft 137, the shatt 137 is given a partial rotation and with'it the heel clamp 135 -whereby the razor is carried over, pivoting as it were upon its back, and the other tace and edge oit the razor is applied to the honing disk for honing movement, these operations being repeated until the desired honing is accomplished, the honing being done substantially' concurrently with the grinding of the first `betore mentioned razor.

Having thus described my invention, it should be understood that there may be modifications thereof and varia-tions therein without departing from the spirit of' the in vention or exceeding the scope of the ap pended claims.
