CARRIER FOR WASHING-BOWLS.

Specification of Letters Patent.

Application filed May 25, 1911.

Patented Oct. 3, 1911.

Serial No. 629,272.

To all whom it may concern:

Be it known that I, CHARLES G. SARGENT, a citizen of the United States, residing at Westford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Carrier for Washing-Bowls, of which the following is a specification.

This invention relates to a washing machine capable of general use, but particularly adapted for washing wool, and it is more especially designed to be applied to that type of wool washing machine in which a reciprocatory rake is employed for moving the wool up to the discharge end of the bowl in an intermittent manner.

The principal objects of the invention are to provide for removing the pile of wool left by the rake in a substantially uniform manner instead of in an intermittent manner as has been the case heretofore; to provide means whereby the pile of fibrous material is acted upon gradually, the top being removed firstand then the lower portions; and to provide an improved form of table for receiving the wool at the discharge end of the bowl, and a chute for delivering it.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which the figure is a side view of a wool washing machine partly in longitudinal central section, showing a pre ferred form of this invention.

The invention is shown as applied to a well-known type of wool washing machine in which the bowl 1 is provided with a reciprocatory rake 2 for intermittently moving the wool up to the discharge end of the bowl, so as to be discharged therefrom between the rolls 3. A driving shaft 4 and pulley 5 and operating mechanism 6 for the rake are shown, but any other type can be used. The usual links 7 and counter-weights 8 are indicated. In this case, however, the

false bottom of the bowl is provided at 13 with a table for supporting the wool slanting upwardly preferably in concave form. From the upper end of this table the. chute 14 slants downwardly to the press-rolls 3.

This form of the parts assists in producing the effects hereinafter described. As ordinarily operated these rakes intermittently deposit large quantities of wool at their feeding ends and then draw back to get another load. The result of this is that the usual carrier which is made to operate uniformly gets a big lump of wool when it is first deposited in reach of it and feeds it to pen to be taken up by the first teeth that strike it after it is deposited at this point. The result of this has been that the press rolls are subjected to unnecessarily rough usage taking a big quantity of wool at one time and then running almost idly. Another result of course is that the wool which is brought through first is not operated upon by the press rolls with the same uniformity as the small quantities that come through later. In order to overcome these deficiencies, the construction of table 13 and chute 14 is provided as has been described, and in addition to this means is provided whereby as soon as the wool is deposited by the rake in position on the table 13 only the parts at the top of the pile are first carried over on the chute 14 and then gradually those parts lower down are taken over so that the wool being fed to the rolls is substantially of a uniform quantity throughout the entire operation of the rake. For this purpose a sprocket wheel 15 on the shaft 4 drives a sprocket wheel 16 of equal diameter by a chain 17. The wheel 16 and a cylinder 18 are fixed on a carrier shaft 19, which is located at the discharge end of the rake at the delivery end of the bowl and over the table 13. This constitutes a rotary carrier for taking the wool deposited by the rake feeding it up the incline 13 and out on the chute 14. This carrier is provided with teeth 20 of varying lengths. The teeth on one side are longer than those on the other side and the intervening teeth vary gradually from the shortest to the longest. In this way it will be seen that the ends of the teeth are arranged eccentrically with respect to the shaft 19. In addition to this the cylinder is set at a certain position on the shaft and the shaft is run by the chain and sprockets, so that the short teeth will be just coming into operation when the rake deposits its load under the cylinder, and the long teeth will come into operation as the rake recedes and while it is starting forward. In this way the wool is fed over in a more uniform manner and the above mentioned difficulties are not encountered.

As the harrow is atthe extreme front of the bowl in its lower position and just starting to move forward, theoretically the least amount of wool is engaging with the carrier. This mass of wool is increased as the harrow continues in its forward orbit and as this mass increases, succeedingly shorter teeth in the carrier enter the liquor until a time arrives when again the least amount of wool is beneath the carrier when the longer teeth, those extending near the false bottoms, are engaging with the wool.

Although I have illustrated and described a particular embodiment of the invention, I am aware that many modifications of the mechanism illustrated can be employed for securing these objects without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but

IVhat I do claim is 1. In a washing machine, the'combination with a bowl and reciprocatory means for moving material along toward one end thereof, of rotary means for delivering from the bowl relatively smallproportions of the material just after it is left at'the end of the bowl by the reciprocatory means, and for delivering larger proportions thereafter until. the next operation of the reciprocatory means, whereby the material is delivered in a substantially uniform manner.

2. In a washing bowl, the combination with an inclined chute, a carrier table ex tending upwardly to the upper end of said chute for receiving the stock, and a rotatable carrier having fixed teeth movable with the carrier in position to lift the stock along said table over on the chute, which teeth project farther toward the table at one period of the revolution of the carrier than at the other periods.

3. In a washing bowl, the combination with a table for supporting the material to be washed, of a rotary carrier for moving the material along the table and expelling it from the bowl, said carrier having fixed teeth, the ends of which are eccentrically arranged with respect to the center of the carrier.

4. As an article of manufacture, a rotary cylinder for a washing bowl provided with teeth of unequal lengths.

5. As an article of manufacture, a rotatable carrier for a washing bowl provided with fixed teeth, the ends of which are eccentrically arranged with respect to the axis of the carrier.

6. In a washing bowl, the combination with a reciprocating rake, of a rotary carrier located near the end of said rake for taking the material therefrom and moving it forward, said carrier having teeth of un equal lengths, the shorter teeth being on one side of the axis thereof and the longer on the other side.

7. In a washing bowl, the combination with a reciprocating rake, of a carrier lo cated near the end of said rake for taking the material therefrom and moving it forward, said carrier having teeth of unequal lengths, the shorter teeth being on one side thereof, and the longer on the other side, and means whereby the shorter teeth are brought into position to engage the material deposited by the rake when the rake moves up to its limit toward the carrier and the longer teeth operate upon the material when the rake is drawn back.

8. In a washing machine, the combination of a reciprocatory member for transferring the material to be washed alongthe bowl thereof, with a carrier arranged at the delivery end of said reciprocatory member and having short teeth and long teeth, and means for operating said carrier to bring the short teeth into operative position when the reciprocatory member is advanced to the extreme position, and to bring the long teeth into operation when it, is retracted.

9. In a washing machine, the combination with a bowl and a reciprocatory mem ber operating therein for transferring material along the bowl, of means for engaging the materialdeposited at the end of the bowl thereby and removing the top of the pile left by said means and then gradually removing the lower portions thereof while the first named means is being retracted.

In testimony whereof I have'hereunto set my hand, in the presence of two subscribing witnesses.
