ERNST RUPPERTZOFBROOKLYN, NEW YORK.
ARTERY-FORCEPS.
SPECIFICATION forming part of Letters Patent No. 547,292, dated October 1, 1895. Application filed June 27, 1895A Serial No. 554,257. (No lnode'ld T at whom it may concern:
Be it known that I, ERNST RUPPERTZ, a citizen of the United'States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Surgical Scissors and Forceps, of which the following is aspecilication.
The object of this invention is to provide scissors, forceps, and like articles which, while capable of being readily taken apart, will have as few as possible loose parts, so that the liability of a part becoming lost is comparatively slight; and the invention resides in the novel features of construction set forth in the following specification and claim,
and illustrated in the annexed drawings, in
which Figure 1 is a plan view of forceps closed. Fig. 2 shows forceps open. Fig. 3 is a section along x w,Fig. 2. Fig.4 is asection along 'y y, Fig. 1.
A B are two jaws or blades having the handles A B respectively. To the jaw B or handle B is fixed a stud or pivot 10, about which is milled a groove 9, leaving a head 8. The spring 6 7 hasa pear-shaped or keyhole slot 11, the enlarged part of which, after the jaw A is placed about pivot 10, is passed over the head Sot said screw or pivot 10, and said spring being then slipped along to bring the contracted part of slot 11 to the groove or milling 9, said spring is held by head 8 from coming up off its seat on handle A.
When takingthe instrument apart, the stud or screw 10 being fixed to handle B cannot become detached or lost, as might occur if this stud were loose, said stud being generally of small dimension. The spring 6 7, bearing against the pivot head 8, will eifect proper tension. The groove 9, being milled all around the pivot, makes a true cylindrical bearingfor the spring, not only leaving the spring free to turn or play, but also facilitating theputting together and separating of the parts, as the spring does not have to be brought to any specially defined position relatively to the pivot for enabling the spring to be mounted or dismounted.
The spring has its part 4 set into a suitable depression or offset 5 in handle A, so that the spring will lie flush with jaw A, and the tail 6 of the spring is contracted or conformed to the contiguous part of the handle A. The structure is thus compact and saves space in putting the same into a case, and besides no projecting parts are formed which are apt to catch or tear. The spring part 4, abutting against ofiset 5, also prevents sliding or longitudinal movement of the spring, so that the enlarged or releasing portion of the keyholeslot 11 cannot move toward pivot 10 until the spring part 6 is sprung or pressed clear of handle A as shown inFig. 2. Accidental separation of the jaws or accidental removal or loss of the springis thus avoided.
What I claim as new, and desire to secure by Letters Patent, is-
The blades A and B, one of which is provided with the offset 5, and the other with the immovable, permanently attached stud 10 extending through the blade having the offset and constructed with a groove 9, and the spring 6, 7, having the key-hole slot 11 engaging the groove of the permanently attached stud and constructed at its forward end portion to lie in rear of and bear against the aforesaid offset for the purpose of locking the spring against longitudinal movement toward the blades when the contracted part of the key-hole slot engages the groove of the stud, substantially as and for the purposes described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
ERNST RUPPERTZ.
