    N° 17,647 A.D. 1893 Date of Application, 19th Sept., 1893—Accepted, 16th Dec., 1893 COMPLETE SPECIFICATION, Obstetrical and Examination Stirrup. I, Joseph Morgan Maurer, of 59 West Wheeling Street Washington, County of Washington, State of Pennsylvania, United States of America Physician, do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the 5 following statement :— In the drawing annexed, Figure 1 is a perspective view of one of the stirrups applied to the side-rail of a bed ; Figure 2 a transverse section on line 2—2 of Figure 1, and 10 Figure 3 a longitudinal section of the rear portion of the stirrup. The object of this invention is to provide improved stirrups adapted to be applied to the side-rails of beds and to operating-chairs to assist the physician in vaginal, womb and rectal operations and examinations as will more fully hereinafter be described. 15 I have shown but one stirrup in the drawing but it is of course understood that they are to be used in pairs. The letter a designates a bar curved upwardly at its forward end, to form a foot-rest a1, and downwardly at its rear end to form one part, a11, of a two part clamp, the bar being preferably formed rectangular in cross- section. Clamped to the underside of the bar a, near the arm a11, is a plate b, 20 which is wider than the bar and is slidably held thereto by a loop c and a bolt dn. The plate b is slotted from its rear end forwardly, nearly its entire length, and the two bifurcated parts thus formed are bent downwardly parallel to the part a11, to form the clamping jaws bl b\ The plate tapers in thickness towards its forward end, and the loop c is secured near its rear end and adapted to closely but 25 not tightly, embrace the bar. The bolt du passes down through a hole in the bar a and through a slot in plate b and is tapped into a plate or bar d extending across the underside of the plate b and tapered in an opposite direction thereto, said bar being provided with a rectangular projection fitting up into the slot in plate b and serving to assist in guiding and steadying the latter. 30 The stirrups may be clamped to the side-rails of beds or to a convenient portion of surgical or other chairs. To secure the device to a bed-rail the part a11 is placed against the inside of the rail with the bar resting on its top and projecting outward from the bed ; the sliding part is then adjusted up close against the rail and securely clamped in place by screwing up bolt d11. The patient lies crosswise 35 of the bed and places her feet in the stirrups, the latter being secured a convenient distance apart. It will be observed that this device is very simple and practical and is eminently useful. The essential feature of the device is the manner of securing it to the bed- rail. It will be seen that the oppositely-tapering plates b and d (the latter being 40 clamped stationarily to the bar) prevent the clamp working loose when once the bolt is screwed tightly. It will also be perceived that the slidable plate has but a limited movement on the bar and cannot become displaced or out of position. Having now particularly described and ascertained the nature of my said inven¬ tion, and in what manner the same is to be performed, I declare that what I 45 claim is : 1. The combination of a bar provided with a stirrup at its forward end and a depending arm at its rear end a slotted plate b secured to the bar near its rear end and provided with a depending clamping-arm, a loop connecting the forward end of [Price 8d.]
