Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed may 16', 1988. Serial No. 483,183.

To all whom it may con ccrn:

Be it known that I, CLAUD H. losrnn, a citizen ofthe United States, residing at Cleveland, in. the county of uyahoga and State of Ohio, have invented a certain new and useful Improvement in Valves, of which l exact dcscription, reference being had to the accompanying drawings.

My invention relates to valves, and more particularly to valves which are applicable as cut-out valves for use with engines to divert the exhaust directly into the atmosphere and for the operation of horns from the exhaust of an engine, especially horns of the type shown in my patents $02,386 and Generally speaking, the invcuiiou may be defined as consisting oi the combinations ol elements embodied in the claims hereto-:1

ncxcd and illustrated, in one cmbodinu-nt, in the drawings forming part hereof, wherein Figure 1 rcprcscnts a view. pur lyin elevalion and partly in section, showing a valve constructed in accordance with my invention applied to the exhaust pipe ol an explosive engine, with a horn applied to the pipe which receives the exhaust when the mulller is cut out; Fig. 2 represents a pm'spcctive view of the valve fitting; lig. 3 represents an ciilarged perspective detail of the valve disks and operating stern; and Fig. t represents a. sectional detail of the valve stem and one of the valve disks, illustrating the manner in which the valve disiv's are mounted. in said.

stem.

Describing the parts by reference characters, 1 represents the valve fitting, the same comprising a'casing having an inlet connec tion 2. and an outlet connection 3 arranged way for a mimparativcly short distance and then extends substantially parallel with such passageway, as shown at (i. Preferably, the end of outlet conncctiorrB and the end of branch (3 are in substantially the same plane. llranch 6 may discharge directly into the almosphcre, but is provided with a thread for the reception of a pipe 7, which pipe may be connected to a horn 8 through which branch 6 may discharge indirectly into the atmosphcrc. 'lhe horn is preferably of the construction shown in my Patents Nos. 802,386 and 808,590 previously referred to.

9 denol es awcb, preferably integral with the lifting and connecting the outlet branches 3; and (3.

l0 denotes a valve stem which extends transversely ol'lhc. branches 3 and (i and the pzissagcviays lhcreim-hoiug journzrlcd in aper- Iurcs formed in the walls ol' said blunches and in a bore l ormcd in the web 1). This stem is provided with a pair of disk valves 11 and 12, the lormer being located within the passageway connecting 2 and 5 and thelattor being located in the passageway in branch (5. These valves are arranged at right angles to each other and are 01' a size to close their respective passageways when swung across the same.- As a convenient and ellicicnt means for securing said valves to their common operating stein, they are mounted in slots 13 and 14 provided in the valve stem and arranged at right angles with respect to each other, the valve tllSliS being secured in place by cotter ins l5 and 16, respectively, which extend enough the valve stem and through the'valve disks. As it is dillicult to locate the bore for the valve stem so that the latter will cross the branches 3 and G at the exact centers thereof, I here the holes through the valve disks somewhat lar er than the diameter of the cotter pins, so that the disks can adjust themselves to the bores of the branches. This construction is illustrated in Fig. 4, wherein the valve disk 12 is shown as provided with a geriora ion 1'2 considerably larger than the p n Hit The valve stem pro jects through tlre'fitting and is provided with an operating handle 17 bent at substantially ri ht angles to said stem. The fitting is provided with a pair of

stop lugs

18 and 19,

i the passageway will be closed when (be located on opposite sides of the valve stem and having reversely inclined laces which are ada ted to en a 'e the anvular extension 17 l) D O of said stem and limit the rotation thoreol'lo a quarter revolution, the parts being so arranged that, when the extension 17 is in engagement with the beveled face of l8, valve 11 will be in full open position and valve 12 will be in full closed position and, when said extension is in engagement with the beveled face oi stop lug 19, valve 11 will be in full closed position and valve 12 will be in lull open position.

From the foregoing description, the operation of my device will be clear. When operating under ordinary conditions, the valve 12 will be closed, and the valve ll will be o pen. By rotating the extension 17 toward stop 18, more or less of the exhaust will be diverted into branch 6. hen the parts are in the positions shown in Fig. 1, substantially all of the exhaust will be diverted into the branch 6 and the muffler will be cut out. A sring 20 tends to hold extensionl? against t is lug l8 and keep the muliler connection open and the outlet branch 6 closed. This spring is connected at one end to the extension 17 and at its other end to any convenient point of aitachinent as to a lug '21 carried by the vehicle frame. Under certain conditions, it will be desirable to use my fitling simply as a relief valve, in which case the valve disk 1 may be removed and valve disk be employed alone. The resistance or back pressure produced by the uiuflicr will be sullicicnt to divert the greater part of the exhaust into the branch 6 without (be ncccssity i'or emuloyiug the valve 11. The construction s iowu and described herein reuders such removal of valve ll extremely simple and convenient. i

it will be apparent'llmt l have produced an extremely simple and couvcuicnt dcvicc whereby llic exhaust gases may bc disclia rged inlo llic muffler or may be diverted at will into the amiosphere (whether directly, or indircctly through the born 8). Furl bormorc, the device may be readilv and conveniently assembled and disassemb ed. A further advantage of my construction resides in the lacithat'the valves ll and 112 are balanced,

so that practically no resistance is offered erases passageway, a valve stem. a valve disk in said passageway, and a valve in said branch.

said valve and said disk. being supported by said stem, said disk'bcia; so arranged that branch is open, and vice versa.
