JOHN HOLTZMAN,OF NEW YORK, N. Y.
HAIR-CUTTER DEVICE.
Application ill-ed December 22, 1921. Serial No. 524,270.
i York, in the county of-New York and State.
of `New York, have invented certain new and useful Improvements in a Hair-Cutter Devicefof which the following is a specification.
This invention relates to a hair cutter device.
Its object is thel production of such a device, in which the cuttingr element thereof can be easily reversed in direction, and over which a draft of air is produced during its operation. A second object is the production of a hair cutter device that can. be operated by a power driven shaft.A A third object of the invention is to provide means, ,20 whereby the driving mechanism thereof is protected from coming into contact with the hair that has been cut.
The device is also applicable to shear wool and various other materials.
-In the accompanying drawings Fig. 1 represents atop plan view of an exempliication of the improved h air cutter; Fig. 2 shows a section of Fig. 1 on the line 2, 2 and Fig. 3 indicates a plan view of some details.
The hair cutter comprises a housing indicated in its entirety by the letter A. v The housing comprises the cylindrical shell 2O open at its top and bottom ends, and divided by the partition 21 into the upper chamber 35 22 .and the lower chamber 23. A journal bearing 24 is formed with the partition 21. The shell yis enlarged in thickness at its upper end 25 and has4 formed therein the journal bearings 26 and 27. A recess 28 is 4 formed in the lower edge of the shell 20. A cover 30 is detachably fastened to the top face of the shell 20. by means of the screws 31. A plurality of inlet openings 32 and a plurality of outlet openings 33 are formed 45 in the shell 20. A ange 34 is formed with the lower end of the shell 20.
A cylindrical cup shaped shell 35 is formed with the shell 20. and has formed therewith at its open end the fiange 36, to which is 50 detachably fastened the cover 37 by means of the screws 38. A plurality oi inlet openings 39 are formed in the cover 37. A jourf nal bearing 40 and' an interiorly threaded flange 41 are formed with the cover 37. The shell 35 with its cover 37 forms a chamber 42. The said inlet and outlet openings cause the air to flow in streams through the shell 23.
A guard plate or comb is indicated in its entirety by the letter B, and comprises the plate which has formed therewith the comb teeth 51. The comb B is detachably fastened to the fiange 34 by means of screws 52.
A rotatable cutter blade is indicated in its entirety by the letter C, and comprises the central disc 53 with the boss 54 and the triangular shaped teeth 55 with the oppositely positioned cutting faces 56 and 57. A spindle 58 extends up from the boss 54 and is fastened thereto by means of the pin 59. The spindle 58 is journaled in the boss 24 and has fastened to its upper end the bevel gear 60. A helical spring 61 extends around the spindle 58 and bears between the lower face of the boss 24 and the upper face of the boss 5.4, to fiexibly force the cutter blade C into proper contact with the comb B. A
portion ofthe cutter blade C extends through the recess 28 of the shell 20. The spring 61 may be omitted and the cutter blade C magnetized to adhere to the guard plate B.
A handle is indicated in its entirety b v the letter D and comprises the sleeve 65, with the exteriorly threaded end 66 and the interiorly threaded end 67. The threaded end 66 is screwed into threaded flange 41. An exteriorly threaded bushing 68 with the flange 69 is engaged in the threaded end 67.
A rotatable shaft 70 with the elongated opening 71 is slidablysupported in the journal bearings 26, 27, 40 and in the bushing 68. Bevel pinions 73 and 74 are fastened to one end of the shaft 70, and its other end hasconnected thereto 'the flexible shaft 75. A propeller wheel is indicated in its entirety by the letter E and comprises the hub 76 from which extend the blades 77. A pin 78 extends through the elongated opening` 71 of the shaft 70 and its ends are fastened to the hub 76 of the said propeller wheel.
A handle 82 is supported on the sleeve 65 and its ends bear between the flange 41 and the flange 69 of the bushing 68.
A bushing 85 extends through the handle l 82 and is threaded into the sleeve 65. A
screw 86 is in threaded engagement with the bushing 85. j Collars 87, 88 and 89 are fastened to the shaft 70, and the end of the screw projects into the space between a pair of Said collars.
To use the hair cutter, the flexible shaft 75 is rotated, by means not shown, which will thereby rotate the shaft 70. The bevel y -of the cutter blade. During therotation of the cutter blade,the propeller wheel E is also turned, and draws air through the inlet openings 39 into the chamber 42. From this latter thepair is discharged through the openings 32 and enters the lower chamber 23 of the cylindrical shell 20. The air is discharged in drafts from the chamber 23 through the outlet openings 33. By this means the porti-ons of the hair or wool that are eut are blown from the cutter, which en-` ables lthe operator to note how the cutterl is operating and assists in the easy and efficient operation ofthe cutter. VIt also keeps the guard plate B, cutterblade C, and other portions of the apparatus clean, by causing a Howe-f air into and through the same. With the parts positioned as indicated in the drawings the cutter blade C will rotate in the direction of the arrow F and the cut-n ting faces 57 of the cutter blade performs the cutting.
When the cutting faces 57 become dull, the cutting faces 56 can be used to y. perform the cutting. To do this the screw 86 is unscrewed from the bushing 85 and the shaft is moved a small distance in the direction of the arrow G. to bring the space between the collars 87 and 88 in line with the axis of the screw 86. The latter is then screwed in place to locate it between said collars. This will cause the bevel pinion 74 to recede from the bevel gear 60'and the bevel pinion 73 will mesh with the bevel gear 60. When rotation is now imparted to the shaft 70 the cutter blade C will rotate in a direction opposite vto the arrow F, and the cutting faces 56 will perform the function of cutting. By this means the life of the cutter blade C is doubled.
lt is to be understood that the'present exemplication of the invention is to be taken as illustrative and not limitative.
