ROASTER FOR COFFEE.
SPECIFICATION forming part Of Letters Patent N0. 673,757. dated May 7, 1901.
Application filed August 25, 1900. Serial No. 28,073. (No model.)
To all whom it may concern.-
Be it known that 1, ROBERT BURNS, a citizen of the United States, residingin the borough of Manhattan, in the city, county, and btate of New York, have invented new and useful Improvements in Roasters for Coffee and other Materials, of which the following is a specification.
This invention relates to a roaster adapted for thorough utilization or exhaustion of heat; and the invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure l is a sectional side elevation of a roaster embodying this invention. Fig. 2 is a front elevation of Fig. 1. I Fig. 3 is asection along mm, Fig. 1. Fig. 4 is a section along at.
1n the drawings is shown a frame or support a, to which is fixed a jacket I), having an outlet or flue c, Fig. 1, for a purpose hereinafter set forth. The frame has bearings or supports 01 for shafts or gudgeons e and f, which are both shown as being hollow. These shafts, with their roaster, are rotated by suitable meansas, for example, a pulley-wheel g.
The roaster is shown with a side or cylindrical shell h, an end 11, and outlets or hollow arms 76, as also with an inner cylinder Z. This cylinder Z can be secured in place by suitable means, as by being slipped into engagement with tube-pieces m, secured to and rotating with roaster h. The arms is communicate with the interior of the inner cylinder, as seen at n in Fig. 1.
The shaft 6 or its collar 0, Fig. 1, connects by spokes or a spider p with the roaster or center part m, and air can enter past these spokes into the inner cylinder Z. Air can likewise enter through hollow shaft f. A burner orcombustible-supply tube q extends through shaft 6 into the inner cylinder and is shown with a stop-cock or valve 7". This burner or heating-tube q supplies combustible or heat to the interior of inner cylinder Z. Of course this tube q could be provided with jets or burners or adapted to burn any suitable combustible-as, for example, vapor or gas. A match or igniter can be introduced through shaft f to ignite the combustible in cylinderl or at burner q.
The combustion in cylinder l can be kept alive by the fuel supplied from burner q, with the air entering past the spiderp and through the shaft f. The products of combustion passing off through the hollow arms 76 enter the space between roaster h and jacket I: and escape through flue c and chimney 1, extending from pipe 2.
The roaster, as kn own, has blades 3, and the steam or vapor coming off the contents of the roaster during the operation passes by arms 7c, through hood 4, into said pipe 2 to escape at chimney 1. This chimney is of course of suflicient size or cross-section to take off the discharge both from flue c and from pipe 2. The head 5 can be rotatable to bring its opening above or below the shaft; but this feature is not claimed, having been set forth in United States Patent No. 241,294, granted May 10, 1881. The hood 4 has a counter or balance weight 6.
By applying heat'at theinside of the roaster a thorough utilization of the heat is effected. As the heat from the inner cylinder does not escape directly to the chimney, but first passes through arms 70 and along the outside of the roaster within jacket Z), the roaster is effectively heated. The outlets it from the innor or heat-generating cylinder Z through roaster h need not be at the end of the roaster, but could be located at any other suitable point. The arrangement of heating-cylinder Z as shown enables inner application of heat without any flame contacting with the coifee or contents of roaster h.
The construction can of course be modified. In the present embodiment of my invention I have shown the roaster h as supported by hollow shafts; but it will be understood that I do not limit myself to such construction, as other supporting means for the roaster may be employed. Such variations are known in the art and do not affect the invention.
The bearing (1 for shaft f is carried by a cross-bar 7, Fig. 2, supported on or bolted to frame a, and about this bearing is seated the hub of head 5, as seen in Fig. 1.
In the drawings I have shown no means whereby access maybe had to the interior of the roaster; but it will be understood that some such means is contemplated, the same being so Well known in the art that it is deemed unnecessary to illustrate the same.
As the inner cylinder has its shell or wall closed or imperforate, flame or combustion products from this inner cylinder cannot pass off into the roaster, but must travel from the inner cylinder to outlets 7c and thence along to flue 0, so as to insure thorough utilization of heat.
What I claim as new, and desire to secure by Letters Patent, is
1. A roaster having an open-ended inner cylinder and hollow shafts and a heating-pipe or burner extended through one of the shafts and terminatingivithin the cylinder,the other shaft being made to open into the inner cylinder for igniting and supplying air substantially as described.
2. A roaster having an open-ended iinper-' fora-te inner cylinder and hollow shafts, and a heating-pipe or burner extended through one of the shafts and terminating within the inner cylinder, said inner cylinder being made to communicate at both endswith the outer air substantially as described.
3. A roaster having an imperforat'e inner cylinder open at both ends, a heat-supply for the inner cylinder, and outlets from the inner cylinder extended through the roaster substantially as described.
4. A roaster having an imperforate inner cylinder open at both ends, a heat supply and outlets for the inner cylinder, and a jacket about the roaster, said outlets being made to lead into the space between the roaster and jacket substantially as described.
5. A roaster having an imperforate inner cylinder open at both ends, a heat supply and outlets for the inner cylinder and a jacket about the roaster, said jacket having a fine substantially as described.
6. A roaster having an imperforate inner cylinder open at bothends, a heat supply and outlets for the inner cylinder, a jacket with which the outlets communicate, and a hood or pipe having a chimney, said jacket having a flue made to communicate with the chimney substantially as described.
7. A roaster having an imperforate inner or heating cylinder open at both ends, a jacket with which the heating-cylinder is made to communicate, a hood or pipe with which the roaster is made to communicate, a flue for the jacket and a chimney for the hood'or' pipe sub stantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
ROBERT BURNS.
