IMPROVEMENT m SPECULUMS.
Specification forming part of Letters Patent No. 147,867, dated February 24, 1874; application filed February 7, 1874. i 4
To all whom it may concern.-
Be it known that I, GUSTAVE W. Sonn- MACHER, of Portland, Cumberland county and State of Maine, have invented a new and Improved Speculum, of which thefollowing is a specification:
My invention consists of a single adjusting screw and nut only, in combination with the arms of the speculumplates, for adjusting them on the arms, to which they are jointed, said screw and nut being at or near the outer ends of the arms, and the screw being jointed to one of said arms and passing through the other, and receiving the adjusting nut outside, so that the arms may be forced together, and the plates forced apart by screwing the nut upon the screw. This plan is employed, instead of a nut and screw for each arm heretofore used,
' the screws being jointed to the arms, on which the speculunrarms are pivoted near said pivots. Besides being cheaper to construct and simpler to operate, this arrangement gives a wider range of movement to the inner ends of the plates,and it affords a means of admethod of adjusting the plates.
plan view, of a speculum with my improved Fig. 3 is a plan view, showing a method of extending one plate beyond the other.
Similar letters of reference indicate corresponding parts.
A represents the plates of the speculum; B, the permanent arms of the plates; 0, the arms, to which the plates are pivoted at D; E, the pivot of the arms (3, and F their adjustingscrew. G is the adjustingscrew, and Hthe nut, which I employ for adjusting the plates by the c rms B, pivoting said screw to one of said arms at its outer end I, and passing it through a slot, J. through the other arm at its outer end, to receive the nut outside, as shown. Thus I obtain a greater range of movement in opening the plates, and have ample facility for shifting them, so as to extend either beyond the other at the inner end, as indicated in Fig. 3.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of the adjusting-screw G and nut H with the arms B of the speculumplates A, substantially as herein described.
GUSTAVE W. SCHUMAGHER.
