FEED STATES PATENT DAVID G-ESSNER, OF WORCESTER, MASSACHUSETTS.

NAPPING-Mel-LCHINE.

Application filed August-28, 1913.

To all whom it may concern:

Be it known that 1, DAVID GESSNER, a citizen of the United States, residing at lVorcester, county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in Napping-Machines, of which the following is a specification. 7

My invention consists in certain improvements in planetary cloth napping machines and refers more particularly to the manner of mounting the napping rolls in the drumheads, my object being to simplify these mountings and thereby secure better results in the working of such machines. v

The invention consists in the improvements to be fully described hereinafter and the novelty .of which will be particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my in vention in theaccompanying drawings to be taken as a part of this specification and wherein,

Figure 1 is a crosssection of a napping drum containing my improved mounting of the napping rolls;

2 is a side view of one .end ther of, with certain parts shown in section;

Figs. 3, 4, 5, 6, 7, 8 and 9 are details thereof;

Figs. 10, 11 and 12 show modifications of certain parts;

Figs. 13, 14 and 15 show in partial section a modification of my improved method of mounting the napping rolls; and

Figs. 16 and 17 show details thereof.

Referring to Figs. 1 and 2, A is one of two end-frames of a napping machine, B are the bottom cross girds, B are the top cross girds, and C are the tie rods uniting the end frames. D is a main bearing on top of one of the frames A, for holding one end of the drum shaft E, to which are keyed drum heads F, one being shown in the drawing, which head is formed with peripheral openings or seats, containing iU-shaped open bushings f, for holding the napping roll gudgeons or journals 9, of the napping rolls it, said. bushings being held in place by screws s threaded through said bushings into the periphery of the head. The rolls may be driven in any suitable manner, as by a circular rack or internal gear E mounted on the shaft E and meshing with gears Specification of Letters Patent.

E on the ends of the gudgeons of said rolls. A traveling grease ring 2' is arranged around the napping roll journals 9 consisting preferably of two sections and united by twov coupling pieces Z into one complete ring. One of these traveling grease rings is placed around the journals 9 at either end of and close to the napping roll bodies. The

has been inserted and bolted in place by screws m, the cams are brought out of touch again with the ring 2' by simply turning the cams until their heavy or high parts point downward, as shown in Figs. 3 and 5, whereupon the rings i are free again, once more to revolve upon and with the journals 9 when the napping drum is set in motion.

I will now describe means for supplying suitable lubricant to the grease ring to be distributed thereby to the gudgeons of the napping rolls:

The drum shaft E has an axial hole or passage 0 drilled into it from its extreme end toward the middle of the machine, which hole extends far enough in to connect with a tube n. set in one of theheads F and eX- tending from the hub of the head outward through its rim, until its end almost touches the traveling grease ring around the journals g of the napping rolls it. By attaching a compression cup, not shown, to the outer end of the drum shaft E a suitable lubricant is forced through the hole or passage 0, and

out from the tube n upon the traveling grease ring 11, from which it spreads to the them by about asiXteenth of an inch, so that the rolls cannot contact with this lip dining the operation of the machine. Fastened to the drum heads F, and placed directly under each napping roll body, are thecups 9 made of pressed steel, which reach out from the drum heads and under the napping roll bodies to about the same extent as the lip 19 of the ring 2' over-reaches the napping roll bodies on the opposite side. These cups g, too, clear the rolls about one sixteenth of an inch, in the ordinary operation of the machine.

Should at any time a journal of one of the rolls break, either through crystallization of the metal in it, or through some other accident, the lip p, on the traveling ring 2', will prevent the roll from flying outward, and the cups qwill prevent the damaged roll from contacting with its neighbors, or from dropping inward, as the machine slows up before coming to a stop, and thus the gen eral destruction of rolls will be prevented, which destruction now is unavoidable. in all napping machines of which I am aware. It it well known that when a journal of a napping roll breaks it always gives way at the inner end near the napping roll body, and the breaking of just one journalv during the operation of the machine often means the destruction of every other roll in'the entire napping roll drum during the mix-up of flying rolls.

Instead of using the cups q, the drum heads F may each be provided with a circular lip or flange 2 projecting inward over the bodies of the rolls, as in Figs. 10 and 11, to stop the napping rolls from dropping in ward, withT-bolts s secured to the drum heads between each pair of napping rolls, to prevent their contacting sidewise, in case an accident should happen, as above mentioned. lVhile I prefer the use of-rthe pressed steel cups 9, still, injury to the rolls will be effectually prevented by the construction shown in Figs. 10, 11 and 12.

While in Figs. 1 and 2 the traveling grease ring surrounds the journals of the napping rolls where they are held in the U-shaped bushings 7 in the heads F, the ring 2', as shown in Figs. 13 and 15, is clapped around the gudgeons or journals alongside of the heads-F directly inside of them and between the head and the napping roll bodies. For this reason. the gudgeons or journals 9 are made correspondingly longer and the cups q are extended in proportion so as to still pro ect under and partlally around the napping roll bodles, so when in case of accident a journal should break, the'broken roll can not contact with its neighbors or drop inside the drum when the machine is being brought to rest. The ring iis lubricated, as before, through a crook-necked tube '11, connecting with a hole or longitudinal opening,'o, With- For lubricating the journals-of the nap Y ping rolls, where they are held in the U-.

shaped bushings f in the heads F, a grease band o, preferably made of felt, is slung around them and buckled together at y (Fig. 15). A loop w, attached to the band a, is slipped over a pin 15, screwed into the side of grease ring i, whereby the grease band is carried around the journals by the traveling grease ring 2' as soon as the machine is setin' motion. The grease felt band 1;, having once been saturated with a lubricant, will communicate the same to all the journals by contact. So much of the pressed steel cups Q, as islocated directly under the journal of a napping roll, and not under the necked tube a.

la is a flat piece of steel, or a feather, inserted into the side of drum head F, and projecting outwardly from its periphery to cause the traveling grease ring 2' to always travel the same path between these feathers 7c and the ends of the napping roll bodies It.

What I claim and desire to secure by Letters Patent of the United States is p 1.
