T on whom it may concern.-

Be it known that I, JAMES M. SWEENY, a

citizen of-the United States, residing at Aspinwall, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Ma-- chines for Making Carbon-Black, of which improvement the followin is a specification.

The invention descri ed herein relates to certain improvements in the apparatus of the manufacture of carbon-black. It has. heretofore been customary in the manufacture of this material to arrange the as-burners in such relation to the surface 0% the plate on which the black is deposited that the flames will impinge at right an les to such surface, and in order to prevent t e products of combustion from extinguishin the flame it has been necessary to arrange t e burners at some distance from the receiving-surface, thereb giving an op ortunity for'the access of suc uantities 0 oxygen and under such conditions as to permit of a hot flame, with the consequent result of burning a portion of the carbon before impact against the surface and lso of a portlon of the black already deposited;

It is the object of the present invention to so arrange the burner and deposit receiving surface in such relation to eac other that the flame will impinge against. the surface at an angle less than a right angle and -the flame Wil have a longer contact with such surface. By reason of this angular impact of the flame the point of impact will be at one side of the burner, and hence the products of combustion produced will not be thrown back directly against and "around the flame, thus avoiding extinguishing the flame and .permitting a closer arrangement of the burner to the deposit-receiving surface.

The invention is hereinafter more fully described and claimed. a I

In the accompanying drawings, forming a part of this speclfication, Figure 1 is a vertical section of my improved form.of construction 'of apparatus. Fig. 2 is a horizontal section view, the lane of section being indicated by the line I II, Fig. 1. Fig. 3 is a similar view to Fig. 1, showing a modification of the apparatus. Fig. 4 is a horizontal section view on a plane indicated by the line IV IV, Fig. 3; and Fig. 5 is a detailed view, on an enlarged scale, of a form of burner.

In the form of apparatus shown in Figs. 1 and 2 the deposit-receiving surface 1 is sup position by means ported at its periphery upon suitable posts or standards 2, said posts or standards being connected by cross-bars 3, to which is secured the upper bearing 4 of the hollow shaft 5. This shaft extends down through a stuffingboxfi onto a suitable bearing formed in the bearing-block 7, through which is formed a passage communicating with the hollow shaft 5. This passage is connected to a suitable source of gas or oil supply, and on the shaft is secured a pulley 8, whereby the shaft may be rotated as required. Radial arms 9 are eecured to the shaft in suitable relation to the plate 1, and to the outer ends of these arms 9 is secured an annular ring 10, provided with a series of burners 11.

at an angle less than a. right an 1e and, preferably, quite acute against the pate 2. It is preferred that the shaft and burners should be rotated in such direction as to exert a pull These burners are so constructed or arranged as to direct the flame on the flame away from the burner, thereby causing a considerable extension of the flame. In order to collect the carbon-black deposited on the plate, from .which it is removed by scrapers 12, supported on an arm 13, carried by the shaft, a basin 14 issecured to the standards below the plate 1, the walls of such basin inclining toward an outlet- .spout 15. In order to insure the removal of the carbon-black from the basin, brushes or scrapers 16 are secured to the shaft so as to sweep around the inner surface of the basin and push the material into the spout. The lower end of the spout is connected to suitable means for conveying the lampbl'ack awaysuch, for example, as a passage 17,in which is arranged a screw 18, adapted to pushthe material'alongithe passage to the discharge-o enin 19.

y In lieu o. revo ving the burners, as .in the construction shown in Figs. 1 and 2, the plate 1 may be secured to a vertical shaft 5, having its lower end mounted in asuitable step 20, the shaft being supported in a vertical of braces 21, preferably provided with antifTiction-rollers 22, b string against the shaft' The burners 11, which are arranged in the same relation to the plate 1' as in the construction shown in Figs. 1 and 2, are secured to an annular pipe 23, connected by a pipe 2 1300 a suitable source of gas or oil supply. The arm 13", carrying the scrapers 12, is secured to one of the posts or side walls so shaped as to direct the car onstandards 2, and a hopper 14 havin its a fan-like flame or to give a narrower flame,

as required by conditions of work. .As stated in regard to the construction shown in Figs. 1 and 2, the point of impact of the flame is moved away from the burners, so that the flame will be eXtcndedand drag along the plate, or the plate will be moved along the flame, thus removing the smoke-deflecting point away from the flame and preventin any smothering or extinguishing thereof an also preventing the combustion of the deposited carbon by the 'fiame. The point at which the smoke and unconsumed gases im pinge upon the plate is carried away from the burners, and as such impingement is at an angle the smoke and unconsumed gases I will be deflected away from thetburner, and

the latter can bearranged in verymlose proximity to the carbon-receiving surfaces/thus preventing the access of such quantities or..

produce a hot carbonranged to direct the ame against the plate at an angle less thania right angle, and in a direction that a pull is exerted onthe flame by the relative movement. .of said parts whereby the reflected'gaseous products 'of combustion are drawn away from'the points of combustion. j
