DABBlNG-BRUSH APPARATUS FOR COMBlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 404,376, dated June 4, 1889.

Application filed October 19, 1888. Serial No. 288,600. (No model.)

To all whom it may concern:

Be it known that I, JAMES L. BALLANTYNE, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Dabbing-Brush Apparatus for Oombing-Machines, of which the following, taken in connection with the accompanying drawings, is a specification. IO This invention relates to improvements in dabbing apparatus for wool-combing machines for the purpose of giving the necessary reciprocating motion to the dabbingbrushes of such combing-machines and to keep the working parts properly lubricated, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, where Figure 1 is a front elevation of the appa- 2o ratus, showing the driving-pulley as removed.

Fig. 2 is a central longitudinal section of the apparatus. Fig. 3 is an interior view of the device, the cover being shown as removed.

Fig. 4 is a cross-section on the line X Y 2- shown in Fig. 1; and Fig. 5 is a side elevation drawn to a reduced scale, showing the manner in which my apparatus is driven.

Similar letters refer to similar parts whereever they occur on the different parts of the drawings.

1 represents the pillar of one of the small circular combs on a wool-combing machine, to which is securedina suitable manner the box-bracket 2, said bracket being provided 3 5 with a bearing 3 for the cam-shaft 4, as shown in Figs. 2 and 4. In one piece with said shaft 4 is made the conical or tapering eccentric or cam, 5. (Shown in Figs. 2, 3, and 4.)

dis the cover of the aforesaid box-bracket, which is secured to the latter by means of the fastening-screws 7 7 and nuts 8 8, which also serve the purpose of securing to the front of the said cover 6 the gibs 9 9, in which the front sliding plate 10 is guided. 45 The cover 6 has a bearing 12, in which the front end of the cam-shaft 4 is journaled, as shown in Figs. 1, 2, and 4. I

13 is a screw-threaded gland surrounding the outer reduced end of the cam-shaft 4,

said gland being screwed into a central recess in the hub 12 and provided with a suitable packing, so as to prevent the escape of the lubricant at this place, as shown in Figs.

2 and 4.

14 is a grooved pulley secured, as usual, to the outer end of the shaft 4, which latter is rotated by means of a belt or cord 15, leading from the pulley 16 on the driving-shaft 17, as shown in Fig. 5. I

18 is a detachable foot or bracket secured to the lower end of the sliding plate 10, preferably by means of a screw 19, (shown in Figs. 1 and 2,) and to such foot or bracket is firmly secured the dabbing-brush 20, as shown in Figs. 1, 2, and 5. By having the foot-piece 18 detachable from the sliding plate 10, as shown, the dabbing-brush, when Worn, can readily be removed from the sliding plate 10 and another one put in its place, and a brush may be taken from one machine and put on another whenever so desired.

21 is a suitable packing secured between the meeting edges of the box-bracket 2 and the cover 6, so as to effect a tight joint be tween said parts to prevent escape of the lubricant at such junction.

In the hollow space inclosed by the boxbracket 2 and cover 6 is located the cam-carrier 22, guided between vertical ribs 23 23 on the interior of the box-bracket 2, as shown in Figs. 2, 3, and 4, said carrier having an upwardly-projecting stern 24,that passes through a perforation in the upper meeting edges of the box-bracket 2 and its cover 6, as shown in Figs. 2 and 3, and is there provided with a screw-threaded gland 25, surrounding said stern and screwed into a recess in the upper part of the said box-bracket and cover, and provided with a suitable packing, as shown in Figs. 2 and 3, so as to effect a tight joint 0 at this place to prevent the escape of the lubricant.

The top and bottom faces of the carrier 22 are provided with hardened-steel faces 26 26, as shown in Figs. 2 and 3, against which the 5 cam or eccentric 5 acts during its rotation, said faces being preferably provided with horizontal projections 27 27, adapted to fit in corresponding grooves in the interior of the carrier22, as shown in Fig. 2. The said faces are preferably secured to the carrier 22 by means of screws shown in dotted lines in Fig. 3, or in any other suitable or equivalent manner. Said steel faces 26 20 may be replaced with new ones whenever worn out without the need of replacing the carrier 22, thus saving a great deal of expense in taking up the wear on said carrier as may be needed from time to time.

To the upper end of the stem 2% is secured the hub 28, the forward end of which is provided with a screw-bolt 29 passing loosely through a slot 30 in the upper end of the sliding plate 10, to which it is secured in an adjustable manner by means of the nut 31, as shown in Figs. 1 and It will be seen that by the rotation of the shaft at and its cam or eccentric 5 a reciproeating motion is imparted to the carrier 22, the sliding plate 10, and the dabbing-brush 20, secured to it. The shaft 4 is longitudinally adjustable in its hearings in one end by means of the regulating-screw 32, screwed through the rear end of the bearing 3, and in the other end by means of the stufling-gland 13, as shown in Figs. 2 and 4, for the purpose of adjusting the tapering cam or eccentric 5 relative to the carrier 22 and its steel faces 26 26 so as to compensate for any wear that takes place on said cam and cam-faces.

The space between the interior of the boxbracket 2 and cover (3, in which the cam 5 and carrier 22 are located, serves as a reservoir to contain the lubricant that is introduced into said chamber through a perforation 33 made in the upper portion of the box-ln-acket 2 or the cover (5, which perforation is normally closed by means of a detachable screw 34, as shown in Figs. 1 and 35 is another stop-screw screwed through a perforation 36 in the back of the box-bracket 2, or any otherpart of the walls inclosing the oil-space, about on a level with the axis of the shaft 4, as shown in Fig. 3, so as to permit the oil-space to be filled to this level.

In charging the oil-chamber the screws 3. and 35 are removed and the oil is poured in at the opening 33 until it commences to flow out through the opening 36, when the said openings are closed by means of the respective screws 3i and 35 and remain in such closed positions aslon g as the device is in use. The lubricant being thus inelosed in the space between the box-bracket 2 and its ccver 6, all unnecessary waste of it is prevented aml the device thus rendered self-lnlnricating.

On the interior of the box-bracket 2 and the cover (3, near their upper ends, I have cast in one piece with said respective parts the curved ribs 37 $37, which serve the purpose of arrestening the lubricant when splashed upward during the upward stroke of the carrier 22, and thus preventing leakage of the lubricant at the place where the spindle 2% passes through the stuffing-gland 25, as shown in Figs. 2 and On theinterior of the respective parts 2 and 6 are also made the curved ribs 38 38, which serve the purpose of conducting the lubricant that has been splashed upward against the rib 37 to the outside of said ribs and down again to the lower part of the oilreservoir, thus keeping the lubricant pro1 )erly circulated therein and causing a proper amount to be automatically fed to the moving parts within the reservoir. The peripheries of the box-bracket 2 and cover (3 being only provided with the intermediate packing 21, there will be a slight space or opening left be tween the abutting edges of the ribs 38, as shown in Fig. at, through which the lubricant that is conducted from the top of the reservoir is gradually returned to the central and lower part of the said reservoir. Should such packing, however, not be suflicient to leave the desired space between said ribs 38 38 for the purpose above mentioned, I may prefer to make in said ribs one or more recesses 39, adapted to conduct the lubricant from the up per to the lower part of the structure. It will thus be seen that the movable parts workin within the space inelosed by the box-bracket and its cover are kept constantly lubricated and the escape of the lubricant is entirely prevented, thus rendering the apparatus noiseless and economical in. its use on account of its self-lubricating properties.

Ilavin g thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. In a dabbing-brush apparatus, the box 2 and box-cover (i, and the cam-shaft 4, journaled in bearings in said parts and provided with the cam or eccentric 5, the carrier and its sliding brush-carrying plate combined with the ribs 37 on the interior of said box and cover, substantially as and for the purpose set forth.

2. In a dabbing-brush apparatus, the box 2, having bearing 3 and regulatiug-screw I: 2, and the cover 6, having stuffing-gland 13, combined with the rotary shaft l, having the cam or eccentric 5, and the carrier 22, having upwardly-projecting spindle 2i guided in the upper part of said box and cover and provided with a stuffing-gland 25, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 10th day of Oetoher, A. D. 1888.
