STOCK-CARRIER.

Specification of Letters Patent.

Patented July 24L, 1917.

Application filed January 17, 1916. Serial No. 72,487.

To all whom it may concern:

Be it known that I, FREDERICK G. SAR- GENT, citizen of the United States, residing at Westford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Stock-Carrier, of which the following is a specification.

This invention relates to a device for carrying stock along a course for any desired purpose, but chiefly for use in drying machines and it is particularly adapted for carrying fibrous stock such as wool and the like and keeping it spread out in a comparatively fine layer while it is being carried through the drying or other machine.

The principal objects of the invention are to provide simple and convenient means whereby the stock will be carried along through a desired course without the employment of the usual complicated mechanism for forcing it along, also to provide a construction in which the carrier for the machine is divided into parts either for the purpose of convenience in case a long carrier is required, or for the purpose of securing a plurality of actions of the drying or other means on the stock while it is being conveyed through the machine. Reference is to be had to the accompanying drawings in which,

Figure 1 is a longitudinal sectional view of a drying machine showing one form in which this invention is used;

Fig. 2 is a similar view of a machine showing another form of the invention in which several sections of the table are arranged one over the other; and

Fig. 3 is a similar view showing further modifications.

In the form of the invention shown in Fig. 1 it is used in a drying machine 10 having a blower 11 for causing circulation of air therethrough for drying purposes. The stock is introduced as usual into the drying machine by a feeding apron 12, a small roll 13 being provided free to rise and fall on the stock and adapted to close the opening 14; through which the stock enters so as to prevent the air blowing out of the machine. This stock as it passes from the feed apron drops on a reciprocating table 15 and it w1ll be noted that two other tables 16 and 17 of a similar character are shown for receiving the stock successively. Each of these tables is reciprocated, as for example, by means of a link 18 and an eccentric stud 19, and 1s shown as resting on rolls 20 to permit it to reciprocate.

The first one of the reciprocating tables 15 is provided with a door 21 hinged to it beyond the end of the frame and adapted to slide up and down on the outer wall for the purpose of preventing the air blowing out of the opening 22 through which the table extends. A partition boX 23 is shown be tween the tables 15 and 16 to prevent the stock being blown beneath the tables. These can be used between each two successive tables if desired, but I have shown a modification between the tables 16 and 17 in the form of a hinged cut-ofi' 24 for preventing the stock from passing backward and the air from blowing through. It will be understood that the so-called tables are of screen cloth, perforated metal, or the like to permit the air to pass through them.

At the dofi'er end of the machine is shown a swing door 25 having a stop pin 26 for preventing the re'e'ntrance of the stock to the drier after it has once passed out under this door which is free to swing by gravity, or by the operation of the wool under it.

By dividing up the table into a plurality of parts I succeed in accomplishing the results of a long table by a less cumbersome method and preferably Without employing mechanism above the tables for forcing the stock along them. By slanting the tables I make use of the action of gravity to assist in moving the stock in the desired direction and at a substantially uniform rate.

The form of the invention shown in Fig. 2 although not shown as applied to a drying machine yet can be used for that purpose. In this case three tables 30, 31 and 32 are shown, each made up of a plurality of screen plates and each resting on rollers 33. Each is provided with means 34 for reciprocating it. These tables all slant downwardly and they are arranged one above the other slanting alternately in opposite directions. In this way a comparatively large drying surface is secured without having a very long drying machine and without increasing the height of the machine in proportion to the output. In this form of the invention a pair of pins 35 is located at the opposite sides of the lower end of each table, these being pressed toward the tables by springs 36. In this way every time the table reciprocates against these pins a jar .can be used, pivoted on arms 42.

in this case the spring pressed abutments are notused and in their )lace the tables are provided with rolls for assisting in feeding the stock. Three different types are shown in this figure. The rolls 40 can be made of plain or perforated metal or wire cloth if desired, and are provided with bent.

teeth. These rolls press down on the stock and force it to move forward with the reciprocating table. Plain wire cloth rolls 41 In this case they allow the stock to pass clownwardly freely under them, but do not allow it to pass upwardly on the reverse reciprocation. Rolls 43 are shown on the third table in the form of drums provided with radial plain ribs 44. In this case each roll has a ratchet wheel 45 on the shaft and a pawl 46 to engage it. This prevents the roll from rotating backward, but allows it to rotate forward to permit the feed of the stock upon the table and prevent its moving backwardly. It will be noted that in all these forms each table slants down toward the next one and delivers to the upper end thereof.

It will be seen that by each of these constructions the feed of the material is assured in a very simple manner. Furthermore the stock is subjected to the action of the air or such other action as may be desired throughout a comparatively long of the invention I am'aware-of' the fact that many modifications can be made therein by any person skilled in the art Without de-- parting from the scope of the invention as expressed in the claims.

Therefore, I do not wish to be limited to the details of construction herein disclosed, but what I do claim is 1. In a carrier for fibrous stock or the like, the combination of an inclined table for supporting the stock, means for reciprocating the table to cause the stockto slide down it, and a roll having projections located over the table and rotatable freely with the stock as the table moves forward for engaging the stock to force it to move forward with the table,said roll constituting means for preventing the stock moving back with the table.

2. In a drier, the combination of a table for supporting the stock to be dried, means for reciprocating said table, a roll engaging the stock on the table, and ratchet means for preventin the roll turning with the stock as the ta 1e moves back.

3. In a carrier for fibrous stock or the like, the combination of a plurality of reciprocating tables for receiving the stock successively, each table being inclined toward the table to which it delivers,rand a partition boX under the delivery end of one table in position to receive the end of the other and capable of receiving and holding stock for preventing the stock blowing back under the upper table.

4. In a drier, the combination of-two -ini clined gravity feeding tables receiving the stock, means for reciprocating said tables to feed the stock down from the bottom of one to the top of the other, and a stationary.

In testimony whereof I have hereunto set. my hand.
