' No. 801,940. I PATENTBD OCT. 17, 1905.







Specification of Letters Patent.

Patented Oct. 17', 1905.

Application filed October 19, 1904. Serial No. 229,156.

To all whom it may concern:

Be it known that I, SYLVENUS WALKER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Smoke-Guard Support, of which the following is a specification.

My invention relates to smoke-guards attached to the central drop-pendant of a gaschandelier by means of a hinged split ring provided with an interior elastic rubber split ring adapted to contact with the central droppendant of a gas-chandelier and be supported in position by pressure of the rubber thereon.

The objects of my invention are to provide a cheap, simple, and convenient adjustable smoke-guard support adapted to be attached to and supported in position upon the central drop-pendant of a gas-chandelier by means of a hinged ring provided with an interior elastic rubber split ring the interior diameter of which is somewhat less than the diameter of the central drop-pendant of the gas-chandelier to which it is to be applied and supported and held in position at the point desired by means of a metal hinged split ring surrounding the elastic rubber split ring and provided on its upper surface with an inward-projecting flange against which the rubber ring contacts when held in position by means of the pressure of the surrounding flanged metal ring when the free ends thereof are pressed inwardly and secured together by means of a screw, the said metal ring being provided with a vertical hole or a number of vertical holes corresponding with the number of gasburners on the chandelier. Now in order to support smoke-guards in the desired position over the burners I provide a suitable number of curved arms, one end of which is bent at a right angle and fitted into the holes provided in the flanged adjustable ring, and the opposite end portions are formed so as to support the common smoke-guards in use.

My invention consists in the construction, combination, and arrangement of the several parts of the smoke-guard adjustable support, hereinafter more fully described, and illustrated in the drawings and specifically set forth in the claim.

In the drawings hereto annexed, which form a part of this specification, Figure 1 represents a side elevation, showing a smoke-guard support embodying my invention as applied to a gas-chandelier when in use. Fig. 2 represents a top plan of a hinged split ring 0011- structed according to my invention. Fig. 3 represents a vertical central section of the hinged split ring inclosing a rubber ring, taken through Fig. 2, shown by horizontal line a. Fig. 4: represents a top plan showing the split rubber ring removed from the surrounding ring. Fig. 5 represents an inverted interior elevation of one-half or one piece of the adjustable holding-ring. Fig. 6 represents a top plan of the same piece.

Similar letters refer to similar parts throughout the several views.

A represents the central drop-pendant of the common well-known gas-chandelier, which serves to illustrate the application of my present invention, which may be applied to the similar partor the drop-pendant of any gaschandelier now in use.

B represents the horizontal arms provided with the burners C, as usual, and need not be described in detail, as any number of burners may be provided for and more than one sup porting device to retain the smoke-guards in position over the burners are contemplated, being secured to the central pendant at different points, as circumstances may require.

E represents a semicircular piece having an inward-projecting flange F on the top portion thereof and one end formed with a vertical hole H for the insertion of a rivet I and the opposite end provided with a similar hole J to receive a screw K, and one end is formed with a projection L on the upper side and the other end with a similar projection L on the lower side, so that when two similar pieces E and E are placed together end to end and loosely held together by a rivet I forms a hinged joint, which will allow the opposite end portions to be turned outward sufliciently to pass by the opposite sides of the said droppendant A of the chandelier when applied and then brought together and secured by a screw K. Now in order that the said hinged split ring E may be secured in the desired position upon the said drop-pendant of the chandelier without injury to the same I provide an elastic india-rubber or felt ring N, having asplit P at one side, so as to permit being placed around the pendant of the chandelier at the point desired and then the said hinged split ring E E placed over around the flexible inward ring N and its opposite ends then pressed together and secured in position by screw K, which will compress the inner flexible ring N upon the drop-pendant A of the chandelier with sufficient frictional contact to sustain the weight of the arms R, the ends T of which are bent downward at a right angle and pass into the holes V, formed in the ring E E, as shown in Figs. 1 and 2. The opposite ends U of the curved arms R are formed so as to support the common smoke-guards W in the desired position above the gas-burners and gas-flames to insure the best results when applied as shown and described.

It will be seen and understood that the'rubher or other flexible ringN is of such interior diameter, less than the smallest diameter of the surrounding ring, as to permit the same to be compressed around the pendant of the chandelier with friction therewith sufficient to sustain the smoke-guards in the best position to prevent any smoke from the burners of the gas-chandelier reaching and discoloring the ceiling of the room from which the chandelier is suspended in the usual manner, as heretofore.

It must be understood that the supportingrings may be made of various sizes, if required, and the supporting-arms of the smokeguards in any number.

It will be seen and understood that the said split ring is composed of two semicircular pieces provided with horizontal complemental projections and depressions, whereby a hingejoint is provided by the ends of two pieces placed together and held loosely by means of a vertical rivet, as shown, and the opposite ends when brought together around the pendant-pipe of the chandelier and secured together by a vertical pin or screw and the supporting-arms constructed with vertical reverse curves and their inward end portions bent vertically downward and supported on the top of the ring. The vertical portion entering the ring permits the curved bent arms to be moved in a horizontal direction in order to adapt the arms to supportthe smoke-guards over the burners. I

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a smoke-guard support, the combination of a hinged split ring composed of two members havinginwardly-projectingflanges, their ends having horizontal complemental recesses and projections, and an interior flexible split ring, and reverse curved supporting-arms secured to said members of the hinged ring by vertical and movable projections, their opposite ends adapted to support smoke-guards; substantially as described;
