Specification of Letters Patent.
Patented Jan. i1, 1916.
Application led October 19, 1914. Serial No. 867,398.
To all whom t may concern.'
` Be it known that' I, HENRY J. ROGERS, a citizen of theV United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in Carding-Engines; and l do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.
rl`he present invention relates to an iniprovement in carding engines.
Assuming a carding engine in perfect working order, with the top flats traveling along the surfaces of the bends of the main cylinder and thence around the top flat chain sprockets and back again, the stripping plate is adjusted closely to the clothing of both the top flats and the cylinder and the top Hats are held in close contact with the top flat disks thereby maintaining them in position to be properly stripped by the stripping comb. T he top iat chain, under such condition of adjustment, is tight and holds the top flats against the top iiat disks alongside of the top flat sprockets. ln use, the chain gradually stretches and then ceases to hold the top flats against the top flat disks, with the result that the top flat clothing comes in Contact with the stripping plate and the top fiat stripping comb strikes the clothing of the top flats passing by it. It then becomes necessary to tighten the chain in order to restore the parts to their previous positions of adjustment. Sometimes the stripping plate is adjusted rearwardly, but this affects the operation of the card and is therefore undesirable, and sometimes the comb also requires adjustment. ln order to hold the top flats in proper position with relation to the top flat disks, it has been necessary to keep the chains under a heavy tension, and this, of
course, only operates to increase the wear and therefore increase the frequency of adjustment of the tension of the chains. The striking of the stripping plate by the clothing has been prevented by readjusting the stripping plate, which has been done in spite of the fact that it caused an increase in the amount of strip. It has also been proposed to provide means for holding the stripping comb at a predetermined distance from the flats, irrespective of the position of the flats due to the looseness of the chain. Finally there comes a time when tightening the chain will not suflice to hold the top flats in Contact with the top fiat disks, and then `a new chain is required.
The object of the present invention is to produce a construction b v virtue of which the top flats will be held in a certain and deinite position with relation to the stripping plate during the time they are passing the stripping plate and with relation to the stripping comb during the time they are passing the stripping comb irrespective of the tension of the chain, so that the clothing will not be brought into contact with the stripping plate, even when the stripping plate is in its advanced position of adjustment, and so that the flats will be properly presented to the stripping` comb, and thus is secured not only the advantage of correct presentation of the parts above referred to, but a lesser chain tension, as a result of which the wear on the chain is very much reduced.
ln the accompanying drawings illustrating the preferred form of the invention, Figure 1 shows a portion of a main cylinder', the top flats, top flat chain, sprocket and associated parts; and Fig. 2 is an enlarged view showing a portion of the chain, sprocket, top ilat disk and top fiat.
rl.`he illustrated embodiment of the invention is described as follows :-'l`he main cylinder 10 is provided with the usual card clothing 11. The dash-and-dot line 12 shows the surface of the bend which determines the relative position of the traveling flats 13 with respect to the main cylinder so that the clothing 14 of the flats is correctly presented to the clothing of the main cylinder. The traveling flats 13 are united by the top flat chain 15 which carries them around in the usual way. The top flat chain sprocket 16 engages the bosses of the flats in driving them. The teeth 17 of the sprocket are curved forward, as at 18, to engage the bosses 19 on the flats at 20 which is beyond the center of the chain link pins 21. The effect of this is to turn the llats on the link pins so as to cause the flats to be pressed against the edge of the top flat disk 22, thereby causing the flats in their progress around the sprockets to be presented in certain and definite positions with relationto the stripping plate 23 and the top fiat stripping comb 24.
By making the top fiat chain sprocket with teeth having their advancing corners projecting forward, the top iats are caused to hug the surface of the top fiat disk, irrespective of changes in the length of the top fiat chain due to Wear and irrespective of whether the chain is tight or loose, so the top flats pass the stripping plate and-the stripping comb in certain and definite positions with relation thereto. Thus the machine is enabled to run with a chain very much looser than has heretofore been customary, and, as a consequence, the chain is subjected to very much less Wear than heretofore, effecting a material saving in the upkeep of the machine and securing, at the same time, a simple arrangement by virtue of Which the top flats are correctly presented to the stripping plate and to the top fiat stripping comb.
Having thus described the invention, what is claimed is 4 A carding engine having, in combination, a main cylinder, revolving top Hats, a top fiat stripping comb, a top flat sprocket and a top fiat disk, said sprocket having teeth the advancing corners of Which project for- Ward and engage the top flats, thereby holding them in proper positions during passage by the top iiat stripping comb.
