SPECIFICATION forming part of Letters Patent No. 555,756, dated March 3, 1896. Application filed March 29,1895. Serial No. 543,711. (No modeL) T0 at whom it may concern:
Be it known that I, FRANK L. BIGELOW, a citizen of the United States, and a resident of the city of New Haven, county of New Haven, State of Connecticut, have invented a new and useful. Improvement in Driers, which is fully set forth in the following specification, taken in connection with the drawings, which form a part thereof, and in which the same letters of reference represent like parts in all figures.
Figure 1 is aview of a drier embodying this invention, taken partly in side elevation and partly in longitudinal section; Fig. 2, a transverse section on lines 2 2 of Fig. 1; Fig. 3, a perspective view of the end of said dryingcylinder.
This invention relates to driers employed in reducing animal ofial, fish refuse, garbage, and other substances, obtaining therefrom grease and matter useful as fertilizers.
One step in the ordinary process of utilizing the valuable elements of offal or other matter is drying the mass in a rotary drier of the type known as the I-Iogel drier. The offal or other mass to be treated must be acted upon with great rapidity by reason of the semidecayed organic animal and vegetable matter it contains. I
As is well known in the art, the drier usually is a horizontal one of cylindrical form, which cylinder is surrounded by a jacket for the circulation of steam. At the same time a longitudinal rotary shaft with stirring-blades constantly beats the material within the drier. To lessen the time necessary for the operation and increase theeiiiciency of the drier, this invention enlarges the heatingsurface by the jacketing of the heads as well as the body of the cylinder. A further and important improvement is to construct at least one head in such a manner that it may be easily detached from the cylinder to give an entrance into the drier for removing the reel, cleaning and repairing, which, from the nature of the mass acted upon, will be often required.
The drier herein described and embodying this invention is of the class known as horizontal driers, and consists of a cylinder A with closed ends B and C, through which extends a longitudinal rotary shaft D, j ournaled in suitable roller-bearings. A gear wheel or pulley may transmit power to the shaft D. Sleeves E are keyed or otherwise secured to said shaft within the drying-cylinder, having arms 6 extending therefrom transversely to the axis of the shaft. The sleeves E usually have four arms, 6, 6, c and 6 extending at angles of ninety degrees from each other about the shaft, though the number and disposition of these arms maybe varied. Crossbars F, called stirring-blades, extending parallel to the shaft, connect the arms and are secured thereto by bolts f. The cylinder A consists of a double shell a and a, having the space a between them for the free circulation of steam, admitted by the pipes G and G from a steam-boiler. (Not shown.) Manholes M in the top or. upper side of the cylinder are for the insertion of the offal, and the dry and disintegrated material is removed through corresponding openings N in the bottom or under side of the cylinder. Stays a connect and separate the two shells, and pipes H and H in the bottom carry off the steam and water.
To increase the heating-surface of the cylinder the head B has likewise an exterior and interior shell, I) and I), connected by flanges to the outer and inner shells of the cylinder, respectively, or directly to the frame of the drier. A ring I is riveted between the two surfaces, making an opening for the passage of the shaft D through the head. Stays brace the double shell of the head B in the same manner as the cylinder, and the steam circulating in the space 111 ay also pass freely into the space If between the exterior and interior heads I) and Z). From this construction it is evident the heating-surface of the drier is greatly increased over the driers hitherto used with a cylinder only jacketed and the operation of drying thereby greatly quickened.
An objection to this jacketed head is that it prevents ready access to the interior of the cylinder, and to obviate this difficulty and at the same time gain the increased heating surface the head C, having also an outer and inner shell, 0 and c, and the ring J, forming an opening in the center for the shaft, as in head B, have a second ring K riveted between the outer circumferences of the shells c and c, forming a jacketed head independent of the rest of the cylinder. Steam is admitted by the pipe g and let out by the pipe h. The outer shell, 0, of this head is prolonged to eX- tend over the end of the cylinder A, to which it is connected by means of bolts la and 7c. The pipes G and H have right-angled tubes g and h with unions by which the pipes g and h may be coupled to them. By breaking the unions of the pipes g and h with the main pipes G and Hand removing the bolts securing the head to the cylinder the entire jacketed head 0 may be drawn away from the cylinder to form entrance to the drier for cleaning and repairing. By this construc tion the process of reducing the offal or other mass is greatly shortened, because of the far greater heating surface, and at the same time repairing or cleaning may be easilyand quickly accomplished.
The details of the construction embodying this invention may vary 5' but What I claim is An apparatus for treating garbage, consisting of a horizontal cylindrical drier; a steamjacket surrounding said drier; a horizontal rotary shaft extending through said drier, and provided with stirring-blades; a detachable steam-j acketed head having a peripheral flange adapted to be attached to said cylinder; a central opening in said head in which the end of said shaft is journaled; supply and discharge pipes for said jacket; and in let and outlet pipes to said detachable head adapted to be connected to said supply and discharge pipes respectively, substantially as described.
In witness whereofl have hereunto set my hand this 25th day of' March, 1895.
