GAS-RANGE-MANIFOLD LOCK.
Application filed December 31, 1925. Serial No. 78,540.
This invention relates to gas heating apparatus, and contemplates certain improven'ients in the gas supply pipes or manifolds and their supports, whereby the turning or twisting of the pipes or manifolds or the cndwise movement thereof in either direction is prevented. The improvements will best be understood from the detailed description to follow.
(if the drawings:
F 1 is a perspective view of a gas stove equipped with a manifold and support therefor constructed in accordance with the invention;
Fig. 2 is a top plan view on an enlarged scale, partly in section, and parts being broken away, of the construction shown in Fig. 1;
Fig. 3 is a vertical section on an enlarged scale, taken on the line 83 of Fi 2; and
Fig. f is a perspective view of a part of the improved support for the manifold.
Referring in detail to the drawings, there is shown therein a preferred embodiment of the invention as used with a conventional form of gas stove or cake griddle G. The stove is provided with a plurality of Bunsen burners, each having a mixing tube 7 formed at the front with a primary air chamber 7, into which projects a gas nozzle 8 tapped into a manifold or supply pipe 9 and provided with a stop cock or valve 11. The manifold 9 is sustained at its opposite ends in sectional supports or brackets 15, having flanges 13 by means of which they are securely fastened to the stove 6 by screws 141-. Each bracket coinprises, as usual, a lined lower member 15 and an upper detachable member '16, the two being held together with the mai'iifold between them by a cl a mpino screw 17.
it is essential that the nozzles 8 be centered in relation to the air chambers 7, or in line with the axes of the tubes 7, as otherwise the proper entrainment of primary air will be seriously interfered with. While the various parts are generally made with great accuracy to meet this requirement, nevertheless it frequently happens that the manifold or supply pipe is disarranged in shipment or in fitting it to the main pipe connections, or for other reasons. This is particularly true when the manifold, as is usually the case and as shown, is made from plain or ordinary tubing which is cylindrical. in contour. To obviate this defect, means are herein provided to lock and hold the manifold in a definite and fixed position so as tomaintain the gas nozzles in proper centered relation to the primary air chambers at all times. Accordingly, e1ther said manifold or its support, without changing the contour thereof, is provided with a projecting member and the other with means coacting with said member to loch: and hold the parts in fixed position. Preferably and as shown, a hole 19 tapped into the manifold or supply pipe 9 in longittulinal alignment with the holes tapped for the gas nozzles 8, so that all of the tapping operations can be conveniently carried out at the same time and with the utmost precision. Into the hole 19, there is screwed a projecting lug 20. The lower bracket member 15 is formed with a locking recess 21, preferably noncylindrical or angular in outline, in which the lug 20 is arranged to fit. To secure the best results, the lug 20 is made to lit snugly in said recess 21, that is to say, so that it will engage the bottom and end walls of said recess with out play. Also, the upper bracket member 16 is formed with a depending rib 22 which, when said member- 16 is in normal position, is arranged to press tightly against the lug 20 and which constitutes in effect the top wall of the recess 21. By this arrangement the manifold is positively locked against displacement in any direction, and in particular against turning or endwise movement, thereby rendering it impossible in fitting or shipment to disturb the proper relation of the parts. Moreover, the arrangement is such that the parts :an only be assei'nblcd in their correct location, and this without any special attention.
It will also be seen that in the foregoing construction the locking means are entirely enclosed and hidden from view, thus rendering. the device foolprool and avoiding unsightly projections or parts in fact, theexter- 'nal am earance of the stove (see Fig. 1) is undisturbed.
The invention in its broader aspects is not limited to the particular construction. shown and described, as many changes may be made in the details thereof without departing from the main, principles of the invention or sacrificing its chief advantages. For example, the manifold or supply pipe and its supporting brackets could be relatively formed in some other way to locate and maintain said supply pipe in the required position. The bracket 19., for instance, could be formed with a projecting ear which could fit closely into a recess in the manifold or supply pipe 9, the ear and the recess being of such relative outline as to insure iast engagement of the ear in the recess.
Having thus described my invention, what I claim is 1. In orfor aheating apparatus, the combination of a Bunsen burner having a mixing tube extending therefrom, a cylindrical gas supply pipe provided with a discharge nozzle projecting into said mixing tube and supported wholly by the supply pipe, a stud projecting from said pipe, a bracket for supporting said supply pipe and comprising a pair of opposed members having curved recesses conforming to and arranged to receive said supply pipe, one of said members being formed with an open notch having side and bottom walls in which said stud is snugly seated. and the other of said'members being provided with lug to close the open side of said notch and arranged to en age the stud projecting from the supply pipe, whereby movement of said pipe in any direction is prevented.
2. In or for a heating apparatus, the combii nation of a Bunsen burner having a mixing tubeextending therefrom, a cylindrical gas supply pipe provided with a discharge nozzle projecting into said mixing tube and support ed wholly'by the supply pipe, a pair of studs projecting from said pipe, a pair of brackets for supportin 'said pipe and arranged at oppo'site ends'thereof, each of said brackets comprising a pair of opposed members having curved recesses con'formlng to and arranged to receive said supply pipe, a member of each of said brackets being forn'ied with an open notch having side and bottom walls in which one of said studs is snugly seated, and the other member of each bracket being provided with a lug to close the open side of said notch and arranged to engage the stud seated in said recess, whereby movement ol said pipe in any direction is prevented.
3. In or for a heating apparatus, the combination of a plurality of mixing tubes extending from Bunsen burners in said apparatus. a. cylindrical gas supply pipe provided with a plurality of alined discharge nozzles projecting into the respective mixing tubes and supported wholly by the supply pipe. a pair of projecting studs screwed into said pipe in alinenient with said nozzles. a pair of brackets for supporting said pipe and arranged at opposit 0 ends thereof, each of said lnackets comprising a pair of opposed members having curved recesses conforming to and arranged to receive said supply pipe, a, member of each of said brackets being formed with an open notch having side and bottom walls in which one of said studs is snugly seated, and the other member of each bracket being provided with a lug to close the open side of said notch and arranged to engage the stud seated in said recess. whereby movement of said pipe in any direction is prevented.
In testimony whereof, I have allixed my signature hereto.
