SAFETY DEVICE FOR GARDING-MAGHINES.
Specification of Letters Patent.
Patented Feb. 19, 1918.
To all whom it may concern:
Be it known that I, OSCAR L. OWEN, a citizen of the United States, residing at Whitinsville, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Safety Devices for Carding-Vlachines, of which the following is a full, true, and concise specification.
This invention has reference to safety devices for carding machines and the object thereof is to provide means for preventing the opening of the cylinder cover while the cylinder is moving.
The invention is an improvement on the device on which a patent was granted to me Oct. 6, 1914, No. 1112829. By the use of this latter device it was found that absolute safety was not guaranteed to the operative because the momentum of the cylinder would cause the cylinder to run some little time after the belt was shifted to the loose pulley, and in consequence the operative was liable to injury in opening the cylinder cover before the cylinder came to a dead stop.
The improvement is fully disclosed in the following specification, of which the accompanying drawings form a part, in whlch the separate parts of my improvement are designated by suitable reference characters in each of the views and in which Figure l is a side elevation of my invention and so much of a carding machine as is directly related thereto; Fig. 2 is an enlarged side view showing the different positions of the locking lever for the closed and open positions of the cylinder cover; Fig. 3 is an enlarged sectional elevation on line A B showing the relation of the locking lever to the driving pulleys.
The main casing of the carding machine is designated 1 and its cylinder cover 2 is located as usual in the front wall thereof adjacent to the casing 3 of the dofling cylinder. The cover is provided with a lateral pin 4 which through the connecting rod 5, and stud 6 operates a blocking lever 7, fulcrumed on stud 17 fixed to the depending part of the bracket 20 bolted to the card casing 1, the lever being provided with a laterally enlarged head 8, which assumes a position as an abutment, in the path of movement of the power controlling device whenever the cylinder cover is opened as is shown by dotted position 7 of blocking lever 7. The power controlling device consists of a belt shipper operating in the usualmanner with the tight and loose pulleys 9 and 10 on the card cylinder shaft and includes the shipper fork 11 and support 12 which is adapted for movement along the horizontal slideway 13 which projects laterally from the bracket 20 above referred to. Motion is imparted to the shipper through an ordinary crank and link connection by means of the rock-shaft 14 which is the controlling shaft of the power device. On the controlling shaft 14 is the abutting arm 15 which acts in conjunction with the enlarged end 8 of the blocking lever 7. The abutting arm 15 normally revolves a half a revolution when the power is turned full on, but when the cover is open and the abutment formed by the blocking lever 7 is in its blocking position, the abutting arm encounters it so that the turning on of the power is thereby arrested.
The above described parts are included in the usual construction of carding machines but the device has been found to be faulty owing to the fact that after the belt has been shifted to the loose pulley and before the cylinder comes to a dead stop the cylinder cover 2 may be opened and in consequence the hand of the operative may be injured by accidentally coming in contact with the slowly moving cylinder. In order to overcome this objectionable feature I make use of the indicating lever 16 pivoted on stud 17. This lever is held in a yielding connection with the lower part of the blocking lever 7 by means of the compression spring 18. One or more camshaped members 19 are in a fixed relation to the cylinder shaft preferably being an integral part of the inside rim of the tight pulley. The lower end of the lever 16 is offset at 21 so as to present the tip 22 in the plane of rotation of the earn points 19. Normally during the running of the card the tip 22 of the lever 16 is held just out of contact with the campoints 19. Now in case the operative attempts to open the cover 2 he is prevented from so doing while the belt is on the tight pulley by the locking device described and claimed in patent to me above mentioned. If, however, after the belt is shifted onto the loose pulley and before the cylinder ceases to rotate, the oper ative should attempt to open the cover the attempting to open the coyenauntilathe cyli-IP. 'der ceases to rotate.
