(No Model.)
, INVENTQR ATTORNEY NITED I STATES PATENT OFFICE.
GUSTAV F. RICHTER, OF NEW YORK, N. Y.
SURGICAL INSTRUMENT.
SPECIFICATION forming part of Letters Patent No. 620,853, dated March '7, 1899. Application filedMarch 22, 1898. Serial No- 6'74,'742. (No model.)
To all whom it may concern:
Be it known that I, GUSTAV F. RICHTER, a citizen of the United States, residing at New York, (Brooklyn,) State of New York, have invented certain new and useful Improvements in Scissors and the Like, of which the following is a full, clear, and exact description.
My invention relates to scissors, shears, forceps, and the like; and it consists in providin g therefor a pivotal connection or joint that will permit the blades to be readily connected or disconnected.
My chief object is to provide in a device of the above character a joint that will permit the blade members to be taken apart easily and quickly, so that the same may be thoroughly cleansed, which members may again be reassembled with ease and in such a manner and by such means as to form an effective connection without weakening any of the parts.
I am aware that separable joints in this class of instruments are not broadly new; but in all of such known devices one or the other part has been materially weakened, which weakening is a decided disadvantage, liable to be productive of ill results where the instrument is to be employed, as is frequently the case, as an aid in surgical operations. In my device, however, the construction is such as to retain the maximum amount of metal and to do away with the necessity of weakening any of the parts in any material respect.
In the preferred embodiment of my invention, Figure 1 represents a plan view of a section of one member of a pair of forceps. Fig. 2 represents a side elevation of the same. Fig. 3 represents a plan view of a section of the other member of the forceps. Fig. 4 is a sectional view of the same. Fig. 5 is a plan view of the forceps, parts being broken away, when the members are in the position to be readily assembled. Fig. 6 represents the en- I at F, to correspond to the angle of the head D, and this cut-away portion is extended around the head of the slot and into the other side of the material abutting thereon, as shown at f. The head D is preferably circular in form with exception of the cut-away portion, and the cut-away part f is such a shape as to allow said head to move therein. The parts are assembled as shown in Fig. 5. The head D is inserted through the opening E, which is preferably just large enough for it to pass, andthe part B may then be shoved to the left, which will pass the stud and head along to the right of the slot until the head comes into the depression f, the bevel of the side of this depression all through being substantially such as to fit the bevel on the head.
The parts A and B may then be swung toward each other in either direction, and the head will then ride into the depression to the rear of the shoulder f, as shown in Fig. 6, and
of the head, as shown, does not weaken the device as a whole or in any material or im* portant part. a
What I claim is- 1. A surgical instrument comprising, a pair of blades, each provided with a handle portion and adapted to cross each other in operation, a pivotal bearing operatively located intermediate their length, consisting of a pivot-stud carried by one of the blades, the head of said stud being of greater diameter than its shank and being cut 0E on one side to allow it to pass the retaining-shoulder, the under side forming a bearing-surface; the other blade provided with a slot into which said stud is inserted, shaped at one end to admit the passage of the head and the other end to retain said head.
2. A surgical instrument comprising, a pair of blades, each provided with a handle portion and adapted to cross each other in operation, a pivotal bearing operatively located intermediate their length, consisting of a pivot-stud carried by one of the blades, the head of said stud being of greater diameter than its shank and being cut off on one side to allow it to pass the retaining-shoulder, the under side forming a bearing-surface; the other blade provided with a slot into which said stud is inserted, shaped at one end to admit the passage of the head and the other end to retain said head, the distance between the bearing-face on the under side of the stud-head to the bearing-face of its supporting-blade being substantially the same as the distance between the bearing-face of the under side of the stud-head and the fiat bearing-surface of the other member when the parts are assembled.
3. A surgical instrument comprising, apair of blades, each provided with a handle portion and adapted to cross each other in operation, a pivotal bearing operatively located intermediate their length, consisting of a pivot-stud carried by one of the blades, the head of said stud being of greater diameter than its shank and being. cut off on one side GUSTAV F. RICHTER.
