LOW-STOCK ALARM FOR CARDlNG-ENGINE FEEDERS.

SPECIFICATION forming 'part of Letters Patent No. 506,046, dated October 3, 1893.

Application filed January 14, 1893. Serial No- 458,326. (No model.) i

T0 at whom it may concern.-

Be it known that I, JAMES KEARNEY, of Plttsfield, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Low-Stock Alarms for Oarding-Engine Feeders, of which the following is a specification.

This invention relates to a low-stock alarm for carding engine feeders, and is specially designed for application to the well-known Bramwell feeder. It is essential to the production of a uniform sliver, that the scale of the feeder receive its full complement of stock so that the delivery will be regular and will accord with the action of the push-board, and to lnsure this, the stock in the box or hopper must always approximate a certain height.

The object of my invention, therefore, is to provide an alarm-device, readily attachable to any feeder of the Bramwell type, without alterat on in the machine, which alarm-device will be set in operation upon the stock in the hopper becoming low, 'i. 6., below the height necessary to a full feed to the scale, thus warning the attendant of the fact and enabling him always to maintain the proper amount of stock in the hopper.

Reference is to be had to the annexed draw ngs and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

Figure 1 shows a side elevation of the lower portion of a Bramwell feeder having my alarm attachment. Fig. 2 shows a top View the alarm device detached and illustrated on an enlarged scale. Figs. 3, 4, and 5 show diagrammatical Views which illustrate the relatlve posltions of the crank-pin of the pushboard gear and the alarm device during the operation of the feeder.

The Bramwell type of feeder is so well known as not to require a detailed descrip- 5 tion here.

It will be sufficient for an understanding of my invention to designate a few parts of the machine appearing in the accompanying drawings.

The letter A designates the stock receptacle or hopper of the feeder; a, the shaft of the lower spike-apron roller; 19 levers which actuate the push-board; c, a gear-wheel having a wrist-pin d; e, an adjustable rod connecting said wrist-pin and the near push-lever b; and f, designates the change-gear meshing with the gear-wheel, c, and regulating the discharge of the scale.

My alarm attachment is to co-act with the parts above enumerated, and in furtherance of this design a gear-wheel B, is mounted on the shaft, a, of the lower spike-apron roller.

The alarm attachment comprises the following parts: A standard, 0, is fastened to the bed of the machine and hasa vertical adjustment-slot, g. An arm, D, is pivoted at one end on a bolt, h, adjustably fastened in the slot g, and this arm extends beneath the gear-wheel, B, and has a bearing 11, at the outer end; this hearing receives a stud, j, which carries a gear-wheel B. On the inner side of the pivoted arm and adapted to mesh with the gear-wheel B, on the shaft of the lower spike-apron roller, and on the outer side of the arm said stud carries a wheel E, having a number of equidistant radiating arms is, all of the same length. The pivoted arm D, also carries a bell F, and a lever G, pivoted at an intermediate point Z, and having a hammer, m, at one end in a position to strike the bell upon vibration of the lever. The opposite end, n, of the lever projects in the path of the radial arms is, of the wheel E, whereby upon rotation of said wheel the radial arms successively trip said lever-end 'n, and thereby move the hammer at the opposite end of the lever away from the bell, said hammer being returned each time against the hell by 4 a spring, 0, connecting the lever with a rigid stud, p, on the pivoted arm. The pivoted arm D, is connected with the wrist'pin, cl, by a strap q, pivoted on said wrist-pin and a spring r, joining said strap and the pivotedarm, the said spring being adjustably attached to the strap, g, by means of a hook 1', which engages one of a series of holes, W, in the strap.

The operation is as follows:When the wrist-pin d is in the position-shown in Fig. 3,

the push-board is drawn back to the fullest IOO extent, and the scale is discharging. As the wrist-pin advances, the scale closes, and while said wrist-pin is moving to the opposite limit of its stroke,t'. e., to the position shown in g. 4,-the push-board is removing the stock discharged from the scale. At the same time the spike-apron is in operation recharging the scale, and if the hopper is adequately supplied with stock, the scale will be recharged while the wrist-pin is moving to the position shown in Fig. 4., so that when it arrives at this point the spike-apron will cease moving. During this travel of the wrist-pin the arm D, moves freely on its pivot h, and as the wrist-pin travels on to the position shown in Fig. 5, the said arm will be elevated to a position where the gear-wheel B, is brought into mesh withthe gear-wheel B, on the shaft of the lower spike-apron roller. But this gear-wheel B, is motionless, the spike-apron having stopped upon the scale having received its full complement of stock and hence the alarm is not sounded as long as the machine is feeding properly. However, should the stock in the hopper become so low as not to properly supply the spike-apron, the scale will not be fully charged while the wrist-pin travels from the position shown in Fig. 3 to that shown in Fig. 4, and hence the spikeapron will not be stopped upon the arrival of the wrist-pin at the latter position, and when the wrist-pin travels to the position shown in Fig. 5, and brings the gear-wheels B and B into mesh, the now-moving gearwheel B, transmits motion to the gear B, and thereby the multiple-armed wheel E is actuated, and the gong struck. This notifies the attendant that the stock is low in the hopper, whereupon he will replenish the same. Thus an attendant is enabled to keep the feeder properly supplied, which will result in greater regularity in the sliver. The spring T, which is interposed between the wrist-pin of the push-board gear and the pivoted arm D, will be adjusted so that the above result will be insured, and the yielding nature of the spring will prevent breakage of the teeth of the gears B, B, when they are brought together.

It is evident my invention may be embodied in dilferent forms from what is here shown. Having thus explained the nature of the nvention and described a way of constructmg and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is 1. In a feeder for carding engines, the combination of a spike-apron; push board operatlng mechanism; and an alarm connected with said mechanism, and arranged to receive motion from the spike-apron, substantially as described.

2. In a feeder for carding engines, the combination of a'spike-apron; push-board operating gear having a wrist-pin; and a pivoted arm connected with said wrist-pin and carrying an alarm device arranged to receive motion from the spike-apron.

3. In a feeder for carding engines, the combination of a spike-apron; a gear-wheel fast with one of the spike-apron rollers; pushboard operating gear having a wrist-pin; a pivoted arm connected with the said wristpin and carrying a gear-wheel to mesh with the gear-wheel of the spike-apron; and an alarm device actuated by said gear-wheel on the pivoted arm.

4:. In a feeder for carding engines, the combination of a spike-apron; a gear-wheel fast with one of the spike-apron rollers; pushboard operating gear having a wrist-pin; a pivoted arm carrying a gear-wheel to mesh with the gear-wheel of the spike-apron and an alarm-device actuated by said gear-wheel on the pivoted arm; and a yielding connection between the pivoted arm and wrist-pin.

5. In a feeder for carding engi nes the combination of a spike-apron; a gear-wheel fast with one of the spike-apron rollers; pushboard operating gear having a wrist-pin; a pivoted arm carrying a gear-wheel to mesh with the gear-wheel of the spike-apron and an alarm-device actuated by said gear-wheel on the pivoted arm; a strap pivoted in the wrist-pin; and aspring adjustably connected at one end with said strap and at the other end with the pivoted arm.

6. In a feeder for carding engines,the combination of a spike-apron; a gear-wheel fast with one of the spike-apron rollers; pushboard operating gear having a wrist-pin; a pivoted arm connected with the said wristpin and carrying a gear-wheel to mesh with the gear-wheel of the spike-apron; and an arm arranged to rotate with the first named gear-wheel; a bell on the pivoted arm; and a lever having a hammer at one end to strike the bell and its opposite end projecting into the path of the arm which rotates with the gear-wheel on the pivoted arm.

7. In a feeder for carding engines, the combination of a spike-apron; a gear-wheel fast with one of the spike-apron rollers; pushboard operating gear having a wrist-pin; a pivoted arm connected with the said wristpin and carrying a gear-wheel to mesh with the gear-wheel of the spike-apron and a multiple-arrned wheel to rotate with the gearwheel of the pivoted arm; a bell on the pivoted arm; and a lever having a hammer at one end to strike the bell and its opposite end projecting into the path of the multiplearmed wheel.
