    N° 6646 A.I). 1894 Date of Application, 3rd Apr., 1894 Complete Specification Left, 31st Dec., 1894—Accepted, 23rd Feb., 189b PROVISIONAL SPECIFICATION. Improvements relating1 to Obstetrical Forceps and other Surgical Instruments. I, Walter Cuttell Longmate, of Denmark House, Wellington Road, South, Hounslow, in the County of Middlesex, Surgical Instrument Maker, do hereby declare the nature of this invention to be as follows :— My invention relates to obstetrical forceps and other surgical instruments, aud 5 has for its object to provide improved means for securing the handles to such instruments. It has heretofore been customary in the case of obstetrical and other surgical instruments to fix the handles thereto by brazing, which however does not make a durable joint, so that, after the instruments have been in use for some time, 10 foreign matter is liable to penetrate through the defective joint into the cavity of the handle and give rise to very serious inconveniences. In order to obviate these inconveniences I jjrovide each branch of the forceps or other surgical instrument with a flattened part or plate, and secure at one end of the same a screw having a taper head similar to that of a counter-sunk screw and 15 protruding from the plate. In lieu of such a screw 1 may employ any projection of dove-tail or other appropriate section, fixed to or forming one piece with the aforesaid plate. In one end of the handle designed to be attached to the plate, which as usu il is made hollow, I form a groove of dove-tail or other shape, corresponding in 20 transverse section to the shape of the projection on the plate, so that when this projection is caused to engage with the aforesaid groove the end of the handle will be Crmly held in position. Tiie other end of this handle may be secured to the corresponding part of the plate by a counter-sunk screw extending through the latter into a solid portion of 25 the handle. I may also use a spring catch or the like for the same purpose. It will be seen that this arrangement enables the handles to be easily detached from the instrument, so that all the parts may be thoroughly cleaned after an operation has been performed or when the instrument has become dirty. Dated this 3rd day of April 1894. 30 WALTER CUTTELL LONGMATE. COMPLETE SPECIFICATION. Improvements relating to Obstetrical Forceps and other Surgioal Instruments.
