application mealauly ia,
To all whom t may concer/n:
-. Be it known that l, WILLIAM ELGRAY, a' citizen of the United States, and a resident o f the city of Chicago, county of Cook, and Stateof Illinois, have invented certain new and useful improvements in Hair Clippers, of which the following is a specification.
My invention relates to improvements in hair clippers and more particularly the driving mechanism therefor, the object of the invention being to provide a simple and efficient driving Vmechanism for the clipper which will operate at suitable speed and substantially without vibration thereof.
Other objects will appear hereinafter.
T he invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,
Fig. l is a bottom plan view shown partially in section'and with parts removed of a hair clipper embodying the invention,
Fig. 2 is a transverse vertical sectionv varlatlon and modification without departthereof,
Fig. 3 is an enlarged section taken on line 3-3 of Fig. 2,
Fig. 4 is a. top` plan view. of the cutting head of the clipper with the housing thereof removed, and
Fig. 5 is a section taken on line 5-5 of I i Fig. 3.
, gages a notch 18 in the rear edge of a seri The preferred form of construction as illustrated in the. drawings comprises the usual serrated cutter head 5 having the usual hollow handle` 6 thereon. A driving shaft 7 is mounted in the handle 6 and provided at its outer end with the usual socket 8 for the reception of and connection with the usual iexible shaft 9.
At its inner end the shaft 7 is providedv with a crank 10 having co-mparatively little eccentricity or throw. rllhe crank pin 10 is connected by a linkI 11 witha lever 12 at the point 13 intermediate the ends of said lever. At its upper endl the lever 12 is fulcrumed at 14 and at its lower end said lever is provided with a lug or finger 15 engaging a suitable notch or o ning in a second lever 16. rllhe lever 16 is ulcrumed'at one end in the handle 6 and the other end thereof eniaai. .serial no. 484,795.
blade 19 will be held in operative relation with the cutting head 5 as will be readily understood.
'.llhe arrangement is such that catory motion of the crank pin l0 is multiplied or made greater by the lever 12 and this motion is again 'multiplied or made greater by the lever 16, thus greatly multiplying the reciprocatory eect produced by said crank pin. -lnithis way the crank pin l() may be given but slight eccentricity or throw and will thus operate the cutting vblade 19 with little or no vibration -in the handle 6. ln this way a smoothly operating andpractically noiseless device is produced by simple and easily understood and vre- `paired'parts'and without the use of gearing.
-While ll have illustrated and described the preferred formof construction for carrying my invention into effect, this is capable of ing from the spirit of the invention. therefore, do not wish to be limited to the precise details of the construction set forth,
yextending into said head and operatively connected with said blade; a second lever at the inner end. of said handle and swinging in a plane substantially at right yangles to the axis of said shaft, the lower end of said lever `being operatively connected with said first mentioned lever; and a link operatively connected with said crank and second mentioned lever, substantially as described.
2. A hair clipper comp-rising a cutting the reciproon guide posts`21 on the head 5 neeaaae head; a cutting blade reciprocating thereon; blade to multipl the motion of said first a hollow handle for said head; a driving lever, substantial y as described.
