Application filed J l 12, 1898.
T0 aZZ whom it may concern:
Be it known that LWILLIAM SENIOR, a subj ect of the Queen of Great Britain, residing at Pendleton, Manchester, in the county of Lancaster, England, have invented a new and useful Improved Diiferential Gearing, of which the following is a specification thereof.
This invention relates to that kind of apparatus for grinding the cards of cardingengines known as the Horsfall grinder, the object being to apply thereto a simple and noiseless differential motion for driving the screw from the tube.
The invention consists in the employment of an intermediate worm for actuating the screw from the tube, as hereinafter described.
The invention will be readily understood from the following description on reference to the drawings hereunto annexed.
Figure 1 is an elevation, partlyin section; and Fig. 2 is a section through A A 011 Fig. 1. Fig. 3 is a sectional elevation of the casing a, and Fig. 3 a front view of the bracket a thereof. Figs. 4 and 4 show, detached, the parts carried by the tube. Figs. 5 and 6 show, detached, the worm-Wheel on the screw. Figs. 7 and 8 illustrate two modifications, Fig. 7 being a detached face view of the worm- Wheel used on that shown in side elevation at Fig. 7. Fig. 8 represents asectional plan of Fig.18, drawn to a smaller scale. Fig. 9 is a front View, partly in section and partly cut away, of so much of a Horsfall grinder as is necessary to show the application of this invention. Fig. 10 is a plan of the right-hand end of Fig. 9.
Referring to Fig. 9,e represents the grinder-' wheel of the grinder, adapted to be fixed to a carding-engine, b the tube, and cl the screw.
According to my invention I prefer to provide a circular casing a to be placed on the end of the grinder and a suitable bracket a to prevent it from revolving when fixed on the frame, as usual. The bracket a Figs. 9 and 10, rests in the slot in the usual slotted or forked bracket 0: (fixed to the carding-engine) when the apparatus is dropped into these bearings or brackets 00 to grind the card-teeth. Upon the end of the tube 1) which projects part way into the casing a I fix a suitable bracket b or its equivalent,

less in action, and thus the setting of the grinder is greatly facilitated.
In some cases the fixed spiral thread may be formed on the inner face of one end of the casing, and in that event the form of the worm-wheel will be changed. Such modification is represented in Figs. 7 and 7, where (7. represents the fixed spiral thread on the end of the casing 0. and e is the modified form of worm-Wheel on the same shaft with the worm c, which revolves in the bearings b and gears with the worm-wheel d, as before described.
Another modification is illustrated in Figs. 8 and 8. In such case the shaft c and worm 01. turn in bearings 0 forming part of the casing 00 which is held from turning by a suitable bracket or, as before. The worm 0 is driven by a worm-wheel b on the tube 5 and inturn drives a worm-wheel d on the screw d, which worm-wheel d has a fewer number of teeth than the worm-wheel b to produce the differential motion, as before described. The pitches of the worm-wheels d and 19 must be such as to allow of an angular or wedging action both for driving-wheel and for driven wheel. The greater this angle is the more certain the worm-wheel b is to turn the worm; but so that the worm may in turning rotate the wheel d it is made about forty-five degrees.
I claim as my invention- 1. The combination of a I'Iorsfall grinder having a screw and a tube, with a casing placed on the grinder and provided with a worm suitably driven from the tube, and a worm-wheel in said casing fixed on the screw and adapted to be driven by the said worm substantially as described.
2. The combination of a Horsfall grinder having a screw and a tube, with a casing placed on the grinder and provided with a 'fixed worm a worm-wheel in said casin 7 O fixed on the screw, brackets fixed on the tube -within the casing and carrying a worm adapted to drive the said worm-wheel on the screw, and a wheel adapted to be driven by the fixed worm and to drive the worm car ried by the brackets, substantially as described.
3. The combination of a Horsfall grinder havinga screw and a tube, the said screw Witnesses:
