FREDERICK A. STCHLMANN, CE BROOKLYN, AND ANDREW H. SMITH, or NEWYCRK, N. r., AssIeNoRs To FREDERICK A. STCHLMANN.
Lette/rs Patent No. 00,210, dated February 22. 1870.
The Scheule referred to in these Letters Patent and making part of the same lTo all whom it may concern f Be. it known that we, FREDERICK A. STOHLMANN, of Brooklyn, Kings county, New York, and ANDREW UH. SMITH, of the city and State of New York, have invented and made a Mechanical Leech andthe t'ollowiug is declared to he-a full description thereof.
Our invention consists in a tubular scarifier rotated by a spring, when brought into operation by releasing a trigger; and the scaritier is prepared for operation by winding it up against the action of said spring, and regulating the depth otl eut by a thimble through which the scuritier projects.
In the drawing- Figure lis a longitudinal section of the scarifiercase, the' scaritier and its rod being in elevation;
Figure 2 is a cross-section at the line xx; and
Figures 3 and Ltare longitudinal sections of the exhansting-tubes.
The scaritier d is formed of a tube with al sharpened end set upon a rod b, that extends through to the head c, and around the rod b isa helical spring, d, that is attached :it one end to the rod b, and at the other end the wire of the spring projects into and is held by the slot or inortise in the case e, as seen at 2.
rlhis euse c iucloses the seariiier audrodb, the part-s being retained by the screw 3 entering a neck in the rod b. Around the rod b is a ratchet-wheel, g, and a'lever, It, and pawl 4 are provided to hold the rod b and the scuritier when wouiui up, by means of the head c, against the action of the spring d.
The tube or case e has a screw-thmble, lc, around the scariier a., so as to adjust the dist-ance the searier projects and gauge the depth of cut.
It will now be understood that the searier a is aptroducing a few drops of' ether or similar material, and inserting the same in hot water, so that the ether will v boil and its vapors expel the atmosphere, the mouth of the tube is to be applied over the incision and the ether vapors condensing produce a sutficient vacuum l to cause the tube to adhere and draw the blood similarly to a leech, but more rapidly and reliably.
' The tubel niay he of any desired size, and the mouth be made at the end, as in iig. 3, or at the side as in v. 4.
C`We claim as our invention- 1. The rotating tubular scarier a, rod b, and spring d, in combination with the head c, trigger h, and case e, substantially as specied.
2 1n combination with the foregoing, the screw-- thimble 7c, to adjust the depth ot' cut, as specified.
Dated November 23d, A. D, 1869. ANDREW H. SMITH. FREDK. A. STOHLMANN.
