To all whom it may concern:

Be it known that I, EDWARD F. POLAND, a citizen of the United States, residing at Boston, in the county ofSuli'olk and State ofv Massachusetts, have invented an Improvement in Hydro-Extractors, of which the following is a specification.

This invention relates to hydro-extractors having a belt-drive, and has for its object to provide the receptacle containing the basket with a closing-lid, and with means connected with said lid and adapted to en- 4 gage or interlock with the belt-pulley when the belt-pulley is at rest but not to engage therewith when the belt-pulley is revolving,

. said means controlling the opening of the lid, whereby the lidv can be opened only when the machine is at rest, and said means being also so constructed and arranged as to require the closing of the lid before the machine is started.

The invention involves essentially a trig adapted to be moved into any of the openings between the spokes of the belt-pulley, or it may be an opening especially provided in the belt-pulley, and when thus engaging said pulley the machine cannot be started until the trig is moved out of engagement therewith; and said trig is yieldingly supported so that in case it should be moved into engagement with the pulley while the pulley is revolving the spokes of the pulley will strike the end of the trig and repeatedly move it backward, and produce a loud noise, thereby to notify the operator that the machine has not yet come to rest. Said trig is connected by suitable mechanism with the closing-lid so as to be moved in one direction upon opening said lid and in the other direction upon closing it.

My invention is applicable to any of the well-known forms of hydro-extractors having belt-pulleys at the base of the machine or at the top, or elsewhere disposed, the mechanism connecting the trig with the closing-lid being changed to accommodate the position of the belt-pulley.

Figure 1 is a front elevatlon of a hydroextractor embodying this invention having a closing-lid and means for controlling its movement. Fig. 2 is a right. hand side elevation of the hydro-extractor shown in Fig. 1. Fig. 3 is a fragmentary view of the closing-lid and connecting means. Fig. 4 is a horizontal section on the dotted line .fr-:v Fig. 1. Figs. 5 land 6 are views of modifications of basket 12;'13 and the invention applied to other forms of hydro-extractors than that shown in Fig. 1.

Referring to Figs. 1 to 4 wherein one type of hydro-extractor with belt-drive is shown, 10 represents the receptacle containing the' 14 belt-pulleys over which which also passes around a belt-pulley 15 on the upright shaft of the basket. 18 is a closing-lid for the receptacle 10, and, as here shown, said lid is connected with the receptacle by a hinge 19, of any suitable construction, 20 representing the pintle or pivot-pin of the hinge. Said closing-lid'has a handle 22 by which it may be moved up and-down as occasion may require, thereby to open and close the opening at the top of the receptacle. As represented in said figures, a link 25 is loosely connected at one end to an ear 26 at the top of the hinge, or it may be elsewhere loosely connected with the closing-lid, the other end of said link being loosely connected with a short arm 28 arranged at the upper end of an upright rod 29, said arm being arranged at right angles to said rod or thereabout, whereby upon longitudinal movement of the link said arm'will be swung in a substana belt passes,

tially horizontal plane and said rod will becorrespondingly oscillated. Said link is disposed between a pair of ears 30 arranged at the top of the receptacle by which itis held against lateral movement; and said oscillating rod has suitable bearings on the side of the receptacle. To the lower endportion of said rod a short arm 32 is secured, which is extended from the rod at an angle and is swung back and forth in a substantially horizontal plane by the oscillating rod. Said short arm 32 occupies a position between a pair of pins 35, projecting upward from a bar 36, which is slidably supported in end-bearings provided for it. Said bar is arranged adjacent one of the belt-pulleys, as 13 for instance, and one of its end-portions is movable into and out of engagement with said pulley, as for instance, said endportion is movable into and out of any of the openings between the spokes of said pulley or any opening which may be purposely rovided for it in the pulley. Said slidingar serves as a trig for the beltpulley, as when in engagement therewith said belt-pulley is held at rest. By the connecting-means here shown between the closing-lid and the trig it will be seen that as the lid is raised the link 25 will be moved longitudinally and the rod 29 will be oscillated and the trig will be moved into engagement with the belt-pulley, and as the closing-lid is lowered said trig will be movedl in the opposite direction for disengagement from the belt-pulley. When the trig is in engagement with the belt-pulley the closing-lid is held open and the machine cannot be started for the reason that the trig holds the belt-pulley at rest. When it is desired to start the machine the closing-lid must be closed, and thereupon the trig is moved ont of engagement with the belt-pulley and the belt-pulley is then free to rotate. While the belt-pulley is rotating should an attempt be made to open the closing-lid it will be lseen that the trig will be moved into engagement with said pulley and the spokes thereof will repeatedly engage the end-portion of the trig and will repeatedly move said trig backward, making a loud noise, and thus calling the attention of the operator to the fact that the belt-pulley is rotating and the machine is still running.

Referring to Fig. 5, wherein another type of hydro-extract or with belt-drive is shown, the belt-pulley is arranged at the top of the machine and the closing-lid 18 is connec-ted with the receptacle in the same manner as ypreviously described, and a link is loosely connected to an ear on the hinge of 'the closing-lid, which loosely engages an npright pin 5G, rising from a sliding-bar 57 or trig which is arranged in suitable bearings at the top of the receptacle adjacent the beltpulley 50, said bar being movable into and out of engagement with said belt-pulley in substantially thc same manner as heretofore described, by sliding it in opposite bearings.

Referring to Fig. G another form of hydroi extract or with belt-drive is shown having a belt-pulley G0 arranged at the top of the machine, and in this instance a slidably supported trig G5 is employed which is engaged by one arm (3G or' a bell-crank lever, the

other arm 67 of said lever being loosely conl nec-ted by a link (3S with an ear on the closinglid 1 8. These several forms of hydro-extractors are shown as illustrating some of. those to which my invention is applicable, and I desire it to be understood that other forms may be em loyed in lieu of those here shown; and furt iermore, that other forms of connecting-means between the trig and closing-lid may be employed, and also trigs of other forms, without departing from the spirit and scope of my invention.

I claim 1'. In a hydro-extractor having a beltdrive, a pivotally supported closing-lid for the receptacle containing the basket, a trig slidably supported for engafrement with and disengagement from the belt-pulley, and means connecting said trig with the closinglid whereby the trig is slid upon movement of the lid, substantially as described.

2. In ahydro-extractor having abeltedrive, pivotally supported. closing-lid for the receptacle containing the basket, a bar slidably supported at the side of the belt-pulley and movable intoI and out of an opening in said pulley, and means connecting said bar with the closing-lid whereby it is moved longitudinally upon movement of said lid, substantially as described.

3. Ina hydro-extractor havingabclt-drive, aclosing-lid for the receptacle containing the basket, pivotally supported thereon and arranged for movement upand down, a link loosely connected with said lid and movable longitudinally upon movementV thereof, an upright rod adapted for oscillation, having a short arm at its upper end which is loosely connected with said link and having a short arm at its lower end, and a slidably supported trig arranged adjacent thebelt-pulley and adapted to engage and disengage said pulley, said trighaving means for operatively connecting it with said last-named short arm, substantially as described.

In testimony whereof, I have signed my name to this specication, in the presence of two subscribing witnesses.

EDWARD F. POLAND.
