JOHAN SJASTRAM, CRIPPLEOREEK, COLORADO.

HAIR-GLIFPER.

SPECIFICATION forming part of Letters Patent No. 781,103, dated January 31, 1905.

Application filed October 17,1904. VSerial No. 228,898. i

To all, whom, it may concern.-

Be it known that I, Jol-IAN SJASTRAM, a citizen of the United States, residing at Cripplecreek, in the county of El Paso and State of Oolorado,have invented certain new and useful Improvements in Hair-Clippers; and l do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it apv composed of few parts compactly arranged to permit it to be veasily handled. j

The above and other objects, which will appear as the nature of my invention is better understood, are accomplished by the construction illustrated in the accompanying draw.- ings, in which- Figure 1 is a top plan view of a hair-clipper embodying my improvements. Fig. 2 is a similar view with the cover-plate removed and parts broken away. Fig. 3 is a vertical longitudinal sectional view taken on the line 3 3 in Fig. 1, and Fig. 4v isa detail view showing the pawl-and-ratchet device yfor the driving-gear.

The body portion of my improved hairclipper comprises a web 2, which forms the bottom thereof and is constructed with side walls 45, which terminate at their rear ends in upwardly and rearwardly projecting handles 3 4, which are formed with outwardlyprojecting finger-stops 5 tofacilitate the hanstationary member of the clipper. Ooacting with said stationary cutter member 8 is the movable member 9 of the cutter, which consists of a plate mounted to reciprocate upon the member 8, as clearly shown in Fig. 2 of thedrawings. Said plate is formed with longitudinally-disposed slots 10, which engage .upwardly-projecting studs or pins 11 upon the member 8 in order to guide the movable or reciprocatory plate 9. Said cutter plates or members 8 and 9 may be of any desired construction; but as here shown they are formed with beveled cutting-teeth 12. Upon the upper side of the cutter-plate 9 is a centrally-disposed pivot-stud, the purpose of which will presently appear. The downturned front end of the cover-plate 6 bears on the reciprocating cutter member 9. By tightenmounted upon said shaft within the body or casing2 in rear of the movable cover-plate 9 is a gear 15, which meshes with a pinion 16, disposed directly in rear of said gear and revolubly mounted upon a stud-shaft 17, project ving upwardly from the bottom of the body or casing 2. Secured upon said gear 15 is a spring-pawl 18, which is engaged with and coacts with a ratchet-wheel 19, which is secured upon a polygonal-shaped portion 2O of said shaft 13. Secured upon said shaft 13 directly beneath the cover-plate 16 is one end of a coil-spring 21, which is coiled about said shaft and has its opposite end secured, as at 22, upon the inside of the body or casing 2. Loosely mounted upon said shaft 13 between the ratchet-wheel 19 and the spring 21 is an oscillating lever 23, which extends longitudinally and has its forked forward end 24 loosely engaged with said pivot-stud upon the movable cutter-plate 9 and its opposite forked or bifurcated end 25 loosely engaged with a pin IOO or stud 26, eccentrically disposed upon said pinion 16. By means of this construction it Vwill be seen that when the winding-key 14 is turned in one direction the spring will be wound upon the shaft 13, so that the energy which it exerts in unwinding will rotate the gear 15 and the pinion 16, which latter will oscillate the lever 23 to reciprocate the movable cutter member 9 upon the stationary member 8, the pawl 18 and ratchet-wheel 19 preventing retrograde movement ot' the gear 15 when the shaft 13 is turned to wind up the spring. A

In4 order to quickly stop and sft'art the cutter-blade 9 after the spring 21 has heen wound up, I provide a brake-lever 27, which is pivotally mounted, as at 28, within the body or casing 2. Said lever has its inner end 29 shaped, as shown in Fig. 2 ot the drawings, so as to engage the teeth ot' the gear 15 and form a friction-brake, said end being held normally in engagement with said gear by means ot' a spring 30, disposed between said end 29 and the side of the casing or body 2. The outer end 31 of the lever 2T extends upwardly and rearwardly between the handles 4 and 5 and has its outer portion engaged by a pin 32, slidably mounted in a transverse opening formed in the handle 4. Said pin is provided at its outer end with a head or button 33, and its inner end is provided with a stop 34, which lilnits the outward sliding movement of said pin. Said button or knob 33 is within convenient reach of the operators thumb, which is engaged with the linger-stop or projection 5 upon the handle 4.

r1`heconstruction,operation, and advantages of my invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. By arranging the gears 15 and V16 within the body portion of the casing 2 and pivotally mountand the minor details of construction may be resorted to without departing irom the principle or sacrificing any of the :nlvantages olE this invention.

Having thus described my invention, what I claim as new` and desire to secure by Letters Patent, is-

A hair-clipper having a body portion formed with an integral stationary cutter member at its front end, side walls at its sides, and lixed rearwardly and upwardly projecting handles which form integral extensions ot the rear end of said side walls, in combination with a reciprocating cutter member on said liront portion ot' said body, a cover secured on the side walls and having a downturned l'ront end bearing on the said recimoeating cutter member, a pinion mounted lor rotation in the casing and having an eccentric stud, a gearwheel in said casing between the pinion and the reciprocating cutter member and engaging said pinion, a shal't mounted l'or rotation in the casing and cover and on which the said gear is independently revolubly mounted, a ratchet-wheel lixed to said shaft, a springpawl carried by said gear and engaging .said ratchet-wheel, a spring having one end attached to the said shalt and the other end attached to the easing, means to revolve said shalt to wind said spring, a lever l'ulcrumed to said sha lit, connected to the reciprocating cutter member and having a slot engaged by the eccentric stud et the pinion, a ln'alv'e-lever pivotally mounted in the casing on thel inner side ol: one ot' the handles and adapted to engage the said gear, a spring to normally engage the brake-lever with said gear, and an operating-pin mounted in an opening in one ot' said handles and adapted to operate said. brake-lever, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
