HOT-WATER BAG.

SPECIFICATION forming part of Letters Patent N 0. 685,894, dated November 5, 1901.

Application filed February 23, 1901. Serial No 48,484. (No model.)

To all whom zit may concern.-

Be it known that I, MORTIMER SINCLAIR IVILLIAMS, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Hotater Bags, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to hot-water bags, is designed to obviate certain objections to the hot-water bags now in general use, and consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by' reference to the description of the accompanying drawings and to the claim hereto appended, and in which my invention is clearly pointed out.

In hot-water bags as generally manufactured and in common use the metal inlet and discharge nozzle and its stopper project from one end or edge of the rubber bag, which limits or circnmscribes the uses to which the bag may be conveniently put, on account of the objection to having the hard lump of the nozzle and the hot metal come in contact with the person, and also that there is no convenient means provided whereby the bag can be secured to the person in a fixed position and in firm contact therewith. To obviate these objections, I construct my improved bag as illustrated in ,the accompanying drawings, in which Figure 1 is a plan of a hot-water bag, illustrating my invention. Fig. 2 is an edge View of the same, and Fig. 3 is a vertical section on line A A on Fig. 1.

-' In the drawings, 1 and 2 represent, respectively, the upper and lower walls of the body of the bag, composed of sheets of rubber cut to a rectangular shape, except that the corners are rounded, said sheets being united at their edges by the binding-strip 3, folded over said edges and firmly cemented to the outer surfaces of said sheets in a well-known manner. The upper sheet 1 has firmly cemented to its upper surface, along the middle of its width from 4 to 5, the reinforcing-sheet 6, having a portion 7 of its length at each end detached from or uncemented to said sheet 1, but cemented to the upper portion of the folded sheet 8, the lower portion of which is cemented to the sheet 1, as shown in Fig. 3. The edges of the upper or folded-over portions of the sheets 8 and portions 7 of the sheet 6 are additionally united by the binding-strips 9 to form firm and strong ears 10, each of which has cut therethrough an oblong opening 11, the out edges of the parts 7 and 8, which form the borders of said open ings, being bound by the strips 12, folded over the same, and firmly cemented thereto, as shown in Figs. 1 and 3. V

The upper wall lot the body of the bag has cut through its center and through the reinforcing-sheet 6 an inlet and discharge orifice 13, above and surrounding which is placed the inlet and discharge nozzle 14, comprising the internally-threaded metal thimble l5 and rubber tube 16, having the base-flange 17, which is firmly cemented to the reinforcing sheet 6 and provided at its upper end with the broad upwardly-curved flange 18, having its outer edge reinforced by the binding-strip 19, as shown. An externally-threaded plug or stopper 20 is fitted to said thimble 15 and is provided atits upper end with the flat milled head 21 and at its lower end with the elastic disk 22, which engages theinwardly-projecting annularseat 23, formed on the lower end of said thimble 15, as shown in Fig. 3.

The flange 17 of the nozzle-tube 16 in addition to being cemented to the reinforcingsheet 6 is further strengthened by having the ring of rubber 24 firmly cemented to its upper surface at its outer edge, the outer por tion of said rubber ring 24 being also firmly cemented to the upper surface of the reinforcing-sheet 6, as shown in Figs. 2 and 3. By this construction the hot water bag is rendered much more convenientlyapplicable to all the uses for which it may be desiredas, for instance, if it is desired to place the bag beneath any portion of the person by turning the bag bottom up or with the nozzle downward in the bed the patient may lie directly upon the bag without experiencing any its smooth side in contact with any desired part of the body or limbs.

What I claim as new, and desire to secure by Letters Patent of the United States, is A hot-water bag the two side walls of which are rectangular in outline, except that their corners are rounded, in combination with an t inlet and discharge nozzle located near the center of one-of said side walls; a pair of perforated ears secured to the upper surface of the same side wall, upon the opposite sides of said nozzle, and between it and the edge of said side wall; and a reinforcing-sheet of
