Leners Patent No. 85,975, dated .Tammy 19, 1869.
IMPROVEMENT DOFF'ER FCR GAMING-ENGINES.
v- The Schedule rean-ed to in these Lettera Patent and making part of the same.
To all whom 'it may concern Be it known that I, BENJAMIN D. WHEAT, of Mount Carmel, in the county of Wabash, and State of Illinois, have invented a new an d improved Rin g-Doli'er forWool- (lardingI Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a diametrical section taken through the improved ring-doier.
Figure 2 is a view of the expanding cones and doffer-shaft detached from the cylinder of the doffer.
Figure 3 is a cross-section through the doier-cylinder, taken in the plane indicated by line :c x' in iig. l.
Similar letters of 'reference indicate corresponding parts in the several figures.
This invention relates to anv improvement on the construction of the cylinders of ring-dofers, and is designed to so construct them that they can be ex.
panded or contracted diametricallyfor the purpose of readily removing or applying the doiing-rings or bands, and also for allowing such rings or bands to be tight cned after they are adj usted in proper places upon the cylinders, as will be hereinafter explained.
To enable others skilled in the art to understand my` invention, I will describe its construction and operation.
The drawing represents a very short dong-cylinder,
containing but three rings or bands, but in practice this cylinder may be made of the usual length.
The. cylinder proper consists of two or more longitudinal sections or segments A A, which are preferably made hollow and of cast-iron, with internal partitions that serve to strengthen the sections or segments.
These segments A, which constitute the cylinder,l have their edges c a, lying nearest the shaft B, inclined from the middle of the length of these sections or segments to the ends thereof, as shown in iig. I.
When these segments are all put together around the central shaft B, as shown in iig. 3, spaces will be left for receiving two circular Wedges, C C, which are applied loosely upon the shaft B, so that they can be moved in a direction with the length thereof.
These wedges are constructed with oblong slots b b through them, through which rods D D are passed, which rods also pass through the shaft B and cylindersegments or sections A A, as clearly shown .in figs. 1
-and 3.
The ends of these rods have nuts and heads upon them, to keep them in their places, which nuts and heads are in recesses, c c, made in the segments or sections A, so as .not to extend beyond the circumference bf the cylinder.
AThe rods D serve to prevent the segments A becoming detached from the shaft B and cones C, when the rings or bands are removed from the cylinder, and
these rods also serve to prevent the segments from turning around the shaft B.
The central shaft B has screw-threads cut upon it for receiving nuts d d, by means of which the cones or circular wedges C O can be forcibly moved toward -each other, and the' segments thereby expanded so as to increase the diameter of the cylinder or drum. By turning back the nuts d d, and drawing out the cones or circular wedges O O, the segments constituting the cylinder or drum can be ni'oved nearer to the axis of shaft B, and this cylinder or drum thus reduced in di- '-ameter.
I 'surround the circumference of the drum with thin sheet-metal strips g g, or rings of other substance, leaving their ends lapping but not united together. These strips or rings will serve as coverings for the spaces left between the segments AA, and allow -them to be expanded and contracted, as above described.
Surrounding the covering g, are the dofing-rings or bands G G, which may be constructed in the usual well-known manner.
It will be seen trom the above description that my improved dong-cylinder or drum can be expanded or contracted in diameter by simply adjusting the circular wedges, and that the rings or bands Gr G -can be readily applied, upon or removed from this cylinder or drum, and made as tightthereupon as may be required, which operation of tightening is performed by setting up the nuts and cones after the rings or bands have been properly adjusted in their places. y
Having described one practical mode of carrying out my invention,
What I claim as new, and desire to secure by Letters Patent, is-
l.- A segmental ring-doiing cylinder orldrum, which is made expansibleby means of sliding cones, governed by vnuts and screws ou the central shaft, substantially as described.
2. A n vexpansible deling-cylinder or drum, the segments of which are attached, by rods D, to a central shaft B, substantially as described.
3. The application of one or more expansible covering-pieces g to an expansible ring-dofier, constructed substantially as described BENJAMIN D. WHEAT.
