SPECIFICATION forming part Of Letters Patent No. 572,433, dated December 1, 1896.

Application filed January 20, 1896. Serial No. 576,155l (No model.) Y

To a/ZZ whom, t may concern:

Be it known that we, JOHN T. MEATS and JOSEPH S. EATON, of Taunton, county of Bristol, and State of Massachusetts, have invented an Improvement in Coilers, of which the following description, in connection with the accompanying drawings, is a specification,

like letters on the drawings representing like parts. l

This invention has for its object to improve and simplify the construction of coilers used to coil teXtile material in cans.

In our invention we have mounted the feedrollers of the coiler in a peculiar manner, whereby they may have ample lateral .movement to prevent breakage in case the material which should pass between the rolls becomes wound thereon, a condition which is not infrequent. The roller, which yields to the accumulation of material on it, is so supported that when it once yields to increase of pressure the pressure thereafter during the separation of the rolls is kept substantially uniform, no matter what may be the distance of the movement of one roll from the other.

We have constructed the cover and casingI of the coiling mechanism so that it may be readily opened to gain free access to the coiling devices for inspection or oiling without necessity of breaking the sliver.

Particular features of our invention will be hereinafter more kfully described, andA pointed out in the claims at the end of this specification.

Figure l shows in top or plan view a sufcient portion of a coiler to enable our invention to be understood; Fig. 2, a view showing the cover and casing and some other usual parts in section; Fig. 3, a plan view with the cover separated to expose the rolls, the latter being separated and the trumpet omitted. Eig. 4 is a cross-section of the boxes in which the roller-shafts rotate, the boxes being in their closed positions; Fig. 5, a like view with the boxes separated as they will be when a roll has accumulated sliver upon it; and Fig. 6 is a section in the line .fr Fig. 1.

The pillar or column A (partially shown in Fig. 2) has a suitable foot to rest on the iioor, and at its upper end it supports the bed-plate A', cut awayT centrally to receive the large coiler-gear A2, having an inclined passage A3 to receive the sliver vand deliver it into the usual cans, (not shown,) which stand directly under the said gear. The pillar has a shaft B, driven by power inusual manner, the said shaft having near its upper end a gear B', which engages and rotates the coiling-gear A2, and immediately above the gear B the said shaft-carries a bevel-gear B2, which engages a bevel-gear B3, fast on and rotating the shaft B4 of the main cylinder-roll B5, said shaft also carrying a pinion B, which engages the pinion O, fast on the shaft O', carrying the cylinder-roll O2.

The mainshaft B4 has its bearing in a box D, held in place by a suitable screw D; but the shaft C has its bearing in a box D2, connected to or forming a part of an arm or radius-bar D2, pivoted at D4, so that said bearing can swing laterally when the material passing between the rolls becomes caught and coiled about one or both rolls, the bearing then sliding on the cross-pieces or track E3, attached to the casing E', adapted to turn about a horizontal pivot E2, held in the bedplate. By thus removing the pivot D4 a considerable distance from the rolls any unusual lateral movement of the roll'C2 will throw it out of gear with the roll B5, as shown in Fig. 3, thereby instantly stopping further ceiling or winding movement of the roll O2. The bearing-box D2 may, however, have-this provision of bodily lateral movement by any suitable means other than the long radiusbar D3.

The casing has a projection E, which may be engaged by hand when it is desired to turn the casin g up and uncover the gearing inside of it.

The movable bearing is acted upon by a friction device (shown as a spring a) held in place by a screw a', so shaped as to overlap the bearing D2 to hold the rolls B5 and C2 together, to enable the said rolls to properly act on the sliver and feed the same into the guide A3.

In case the sliver becomes wound about one of the rolls it will continue to accumulate and the rolls must separate or the mechanism will break. The bearing D2 may yield under these circumstances, and as it moves '(see IOO Fig. 5) the friction vdevice cl, continues by its end a2 to act on the bearing and insures that the friction or `resistance 'Which the bearing has to overcome in order to move is uniform. If a spiral com pression-spring should be used, the pressure to overcome would be gradually increased. l

By enabling the roller C2 to yield laterally in a horizontal plane its range of motion is greatly increased and there is no danger of its striking any other part, which would stop it or result in breakage.

Instead of the particular friction Adevice shown We may use any other equivalent friction device acting on the bearingv D2 or its carrrying-arm.

Thecover-plate is composed of two parts d d', mounteclon a pivot d?, vfixed vbya screw cl3 ina lug attached to the interior of the-casing E', and ythe part CZ hasattached to it the sliver-guide d4, which -guidesfthe sliveron its Way into the trumpet e. vThe trumpet e is carried by 1an arm e', pivoted "at cion 'an lear e?, Vherein shown (see Fig. 3') as `erected on thebearing D. By mounting "the vtrumpet independently of `the cover vand dividing the cover the rolls -C2 and Bland theirdrivinggear may be -readily made accessible by'only separating the cover, one par-t of the cover having a suitable catch, as f, shown as a spring adapted to engage a lug f on the other part, the spring having Yan attached button f2, Awhich may be depressed to'disengage ythe spring from the lug.

In our invention -by making the cover in two parts and mounting'the same'on a vertical pivot the cover may be readily swung apart horizontally and fully uncover the rolls and their driving mechanism, Vthe sliver vremaining in the guide and trumpet, and by tipping the casing utp about the vpivot E2 the coiler-'gear may be reached and removed, if desired.

I-Iaving described our invention, what We claimas new,and desire to secure by Letters Patent, is-

l. In ya coiler, the combination with a main roll B5, its shaft, a bearing for the shaft, vand means to rotate the shaft, of .a second 'shaft having a roll C2, pinions-on said shaft to cause the said main shaft to revolve the said second shaft, a bearing for the said second shaft and `a radius-bar carrying the said bearing, `said radius-bar being mounted on avertical pivot located substantially as described, whereby the separation of the said rolls by the accumulation of fiber disengages the said pinions, said radius-bar 'movingl freely in the arc of a horizontal circle, substantially as described.

2. In a coiler, a trumpet, a coller-gear, and a pair of rolls mounted side by side tov feed the sliver into said Geiler-gear, a horizontallymovable bearing for one of said rolls, said bearing having a flattened side, combined with a friction device adapted to ride on the flattened side of the bearing to thus insure 'uniformity of pressure on the material Wound on the roll, substantially as described.

3. In a coiler, the ceiling-gear, feed-rolls located Vabove it 'and relatively movable horizontally, 'and a spring coperating With the shaft carrying one of said rolls to retain the rolls in yielding relation, combined AWith a two-part cover mounted 'on a vertical pivot and movable in a lhorizontal plane from over and to fully expose the :said rolls vand their actuating-gear, each part of the cover being :movable independently of the other-,substantially as described. Y

4. In .acoiler, the two-,part centrally-divided cover mounted on a vertical pivot, one of said parts hav-ing lattached lto it a sliver-guide, combined Witha trumpet 'sustained independently of said cover and With the pair of rolls B5, C2, one of the shafts of said rolls being movable in a horizontal `planeawayfrom'the other of said shafts, substantially as described.

5. `Theshaft B4, its stationarybearing,land vthe shaft C/ and its movable bear-ing,.said two shafts being provided with rolls, combined with a spring suitably secured to the machine, said spring `shaped to yieldingly embrace-said movable bearing, the said Yspring exerting uniform pressure on the top vof vthe said bearing when `the rolls are `unduly separated,sub stantially-as described.

G. In a coiler,:a casing mounted on a horizontalpivoua trumpet carried by said easing, combined With a cover mounted on a vertical pivot carried by `said casing, and centrally apertured to fit snugly around Vsaid trumpet, substantially as described.

AIn testimony whereof we have signed our names to this Vspecification in the 'presence of two subscribing witnesses.
