APPARATUS FOR ADMINI STERING NITROUS-OXIDE GAS.
SPECIFICATION forming To all whom, it may concern.-
Be it known that I, LAIRD W. NEvIUs, a citizen of the United States, residing at Toledo, county of Lucas, and State of Ohio, have in vented a new and useful Improvement in Apparatu's for Administering Nitrous-Oxide Gas, of which the following is a specification. The object of my invention. is to provide a simple and effective apparatus for administer- The gas-receivers now in general use areof 1 two kinds-the rubber bag and the tank or water-sealedholden The objections to the bag are its unsightly appearance, lack of uniform .15pressure, and libility to injury. The tank 1 .or water-sealed holder lacks portability and uniform pressure;jis liable to leakage and freezing, shows the patiffit th' amount of gas being consumed by the lowering of the inner 2o tank into the outer casing, and is attended with inconvenience in changing the water from time to time. In my invention I provide againstjthese objections by constructing an apparatus having a flexible receiverwith a movabletopor bottom operating by means of a balance weight or weights within a rigid outer casing, so arranged that the top of the flexible receiver descending, or the bottom thereof ascending,within the outer; case will secure the 3o requisite pressure for the free and uniform outfiowof gas when being administered. 1 I prefer, however, the movable top, partially counterbalanced by a weight, having pointer orindex-flnger for a guide-scale attached, said top l 5 moving vertically within the outer casing, as
the gas is admitted to the receiver or dis- 1 charged therefrom. b b Inthe drawings,Figure1representsavertical sectional view of my apparatus; Fig. 2,

In Fig. 1 2 represents my flexible receiver supported'by end 10 over pulley 9, and partially' counterbalanced by weight 16,- (shown in Fig. 3, the whole operating vertically within the rigid outer casing, 3. 11 11 represent the guides which keep the top of flexible holder in a horizontal position, and prevent its oscillation, at the same time allowing it. free play within theouter casing. movable bottom, between the periphery of which and'the outer casing the flexible-sides of the receiver are securely held in position. 6 is the supply-pipe through. which gas is introduced from an outside cylinder. 7 is the exhaust or inhaling pipe; 8, its cut-off; 13,
the wire guards attached to the removable bottom, so as to prevent the top or flexible sides of the receiver from falling upon and. obstructing the openings in the supply and ex: haust pipes. 12 is the brace to which pulley 9 is hung, and 14: the cap or cover which fits upon and incloses the outer casing. A

In Fig. 2, 19 is the guide-scale, so divided as to indicate the number of gallons introduced into or discharged from the receiver. 18 is the pointer or index-finger attached to weight 16, hung in box 15, (shown in Fig. 3,) and by means of a vertical opening in the face of the scale-guidehaving free play thereon. 7 is the exhaust-pipe, and 8 its cut-off. The dotted lines near the top indicate the line of the brace to which pulley 9 is hung. b a

The dotted lines represent the flexible receiver within the casing and the under line of the re- I InFig. 4, 3 is the outer casing; 41., top of flexible receiver; 10, center line of pulleycord; 11, guides to top of flexible holder; 6,

The outer casing should be constructed of metal or other suitable material. The inner receiver should be of flexible material, preferably rubber. The top of the flexible receiver should be so adjusted by means of the counterbalance-weight as to secure for it the requisite pressure for a free and uniform outflow of gas. The supply and exhaust pipes, from the line of the outer casing to the connecting-tubes, which enter the removable bottom of the receiver, may be of flexible material, so as to be readily disconnected in case it becomes necessary to remove the bottom.
I am aware that a flexible receiver within an outer case has long been known in connection with the manufacture and distribution of illuminatinggas, and that the slotted tube having the weight and pointer suspended therein has been used independently of the outer casing. My improvement consists in combining the slotted tube with the outer casing,'so as to form a part thereof, and in providing a scalebar on the surface of said casing, so that by means of the pointer attached to the weight hung in said tube, and the slot along the face of said scale-bar, through which the stem'of the pointer has a vertical movement, an ac curate measurement is secured of the inflow and outflow of gas.
WVhat I claim as my invention, and desire to secure by Letters Patent of the United States,
1. In a gasometer having a flexible receiver within a rigid outer casing for administering nitrous-oxide gas, the combination of a weight scale-bar on the face of the outer casing, a
sigspended weight connected with the inner receiver and imparting a vertical movement to the index-finger attached to said weight as the receiver ascends or descends, substantially as set forth.
3. In a gasometer, the combination of outer casing, 3, flexible receiver 2,weighted top 4, balance-weight 16, removable bottom 5, with guard 13, pointer 18, attached to weight, guidescale 19, on which pointer indicates the inflow and outflow of gas in a receiver, substantially as and for the purposes set forth.
