FEED-p-INDICATOR FOR CO'IVTON-OPENERS.

SPECIFICATION forming' part of Letters APatent No. 224,185, dated February 3, 1.880.

ApplicationwledNovember 21, 1819. Y

To all whom it may concern:

Be it known that I,'JOHN HILL, of Columbus, in the county of lVIuscogee and State of Georgia, have invented a new and Improved Feed-Indicator for Cotton-Openers; and I do hereby declare that the following is a'full, clear, and exact description oi' the same, reference being had to the accompanying drawand loosen the tussocks of cottonas they comefrom the bale and distribute theber in the form of a ieece. In usingthese openers two are4 sometimes employed together toV act successively upon the cotton; or one-opener may be employed in connection with a lappingmachine,the function of which latter is to press together and compact into aa'eece. In either case a hollow trunk has been employed as a conduit, in connection with a blast of air passing`through the same, to act as a vehicle to carry the ieece from one opener to the other, or from the opener` to the lapping-machine, which secondl machine is generally located upon a different floor, or at a point more or less remote from the first.

My invention has more special reference to what is known as Kitsons Trunk System of Opening Cotton 5 butitcan be used in any similar system where the opener is located at some distance from the secondopener or lapper and cotton is supplied from the first to the second through a trunk or ilue.

The invention consists inmaking the boxesk ofthe upper feed-roll of the second opener or lapper vertically adjustable and connecting them with an index-hand within sight of the operator at the rst machine, so that said operator, at a point remote. from the second machine, can tell the amount of cotton fed to the second machine by the rise or fall of the movable roller due to the passage of la greater or less quantity of cotton to the second machine.

In the drawings, A and B represent two` oors of the building, upon which are located, respectively, the rst and second openers, C and D,of which, as here shown, the first opener, G, is located on the first ioor, andthe second opener, D, on the floor above, and which second opener,D, maybe supplantedbya lapping-v machine, as described.` These two machines are connected by a hollow trunk or flue, E, whichleads fromthe discharge end of the iirst machine to the feed end of the remote machine, andV through which a blast of air is forced to carrythe iieece along.

Cotton is supplied to the first machine, and after its bers are loosened it passes, in connection with the propelling drafts of air and collecting-condensers, directly to the feed attachment of the second machine, the amount of cotton supplied to the second machine being determined by that passing through the first.

' For evenness of' results it becomes important that some ready means of determining the amount of cotton being used by the second machine should be afforded to the operator feeding the supply to the first. 'lo accomplish this I place on each journal of the upper feedroll, F, of the second machine a verticallymovable box or half-box, a, which rises and falls according to the thickness ,of the feed passing between the rolls. From each ot' these boxes I suspend links b, loosely attached at vtheir lower ends to the opposite ends of a horibar c'and lever d being close to the fulcrum of the latter, so that the range of movement will be multiplied to increase the sensitiveness of the indicator. y

The weight c may be supplanted by a spring, and its gravity or tension is sutlcient to take up all lost motion in the connections and to cause the boxes to closely follow the move-' ments ofthe journals.

To the weighted end of the lever d a conroo necting-rod,j`, is attached, whose position is determined by the relative situations of the two machines and the connecting-trunk. As shown, it passes downward to the door beneath, where the first machine is located, and connects with the crank g of a rock-shaft, 11 arranged in bearings on the trunk, which latter has a second crank, t', from which is suspended a rod,j, carrying an index-hand, 7:, adapted to move over a scale, in front of the operator, which scale is determined by the extreme limit of movement between the feed-rolls ofthe second machine.

With this arrangement it will be seen, without further description, that the operator below has constantly before him an indicator to show the amount of cotton passing into the second machine.

With the arrangement ot' the bar c and lever d it is not necessary that there should be a regular and even thickness of sheet under the bile of the feed-roll of the second machine, as the suspended bar c is differential as attached to the lever d below-z'. c., the movement of the lever d is commensurate with the quan tity ot' cotton fed, and not simply the thickness of the iieece passing between; for if a large bulk ot iieecc passes at one end of the roll and nothing` at the other, the horizontal bar c acts as a lever to rise only at one end, and as its connection with the subjaceut lever is at a middle point it only pulls said lever half the distance up that it would if both ends raised the distance of the maximum thickness of the leece.

The weight or spring attached to the long arm of the second lever I use not only to take up lost motion, but as a power to hold into position the top roll for proper strength of bite.

As a modification of my invention I may employ a different train of mechanism for transmitting the motion from one machine t-o the other-as, for instance, a cord or wire may, inV

many cases, be used to advantage in the place of the connecting-rod, rock-shaft, and cranks.

In defining the scope of my invention more clearly, I would state that I do not limit myself to combining the index-hand of the rst machine with the movable roll of the second, but may combine it with any two parts of the second machine through which the sheet or 5o iieece of cotton is fed when one of said parts is made adjustable to suit the thickness of the fleece being fed, and by such automatic adljustment operates the indicator of the irst machine. 5 5

I disclaim fully such indicators when combined simply with the feed devices of' the same machine.

Having thus described my invention, what I claim as new is- 6o 1. The combination, with the two machines C and D, situated atadistance from each other., and connected by a trunk, as described, of bearings mounted upon the second machine, through which the tleece is fed to said machine, one of said bearings being movable, as described, aud adapted to accommodate itself automatically to the varying thickness of the fleece, and an indicator-hand situated upon the tirst machine and connected with the said 7o movable bearing of the second machine, substantially as described.

2. The combination ot' the two machines C D, the connecting-trunk, the feed-rolls mounted on the second machine, and one ot' which 75 is made movable, the links b, horizontal suspended bar c, the lever d, and the indicator,

and mechanism, substantially as described,

connecting said lever with the said indicator on the first machine, as set forth.
