Applicationifiled May 28, 1918; Serial No. 237,116..

To all whom it may concern:

Beit known thatI, STEPHEN V. Joyce, 2). citlzen of the United States, residing. in

the borough ofManhattan, city, county, and.

State of: New York, have invented certain new and useful Improvements in Chutes for Proportioning and Forwarding Materials, of which the following is a specification, reference being bad to the accompanying drawings andthe characters of reference marked thereon.

My invention relates to improvements in chutes adaptedto be used for forwarding materials, such as ashes, lime, sand, broken stone, cement, gravel and similar materials,

and the structures for that purpose may be,

built sufiiciently large and strong to forward materials of that character; but the device may also be modified, decreased in size, and otherwise adapted to be utilized An exampleof my invention is illustrated in the accompanying drawings, in which Figure 1. is a View of one such slideway, partly in section; Fig. 2 is a plan of two such slideways joined to each other; Fig.

is a sectional view on the line 33 'of'Fig. 2 Fig; 4 is a sectional View on the line H. of Fig. 2; Fig. 5 shows a modification of the sliding gates to be, attached for opening and .closing the slideway, and Fig, 6 is a section of Fig. 5 ontheline 6-6;.Fig. 7 is a planshowing the chute in positiondisposed. so as to receive the materials separately at the upper.- end, and to carry the. proportioned materials to the. discharge end.

A is the chute, in this example of "my -invention, composed'of two slideways. B and C1. Theslideway B may be composed of" exterior side piece 1, and interior sidepiece 2, and a-floor 3, when the slideways, are made separately and bolted together as shown in Fig. 3; but the middle portion may be made of one solid piece as shown in Fig.1 4; 1 is a support forthe bearing of the shaft.

5, which shaft supports a working beam or' bar 6, to which it is. secured by collars-7; 7;

the interior endof the shaft 5 is provided. with a suitable clutch 8, rotating in a support 9, secured to the side .piece 2; the clutch 9 is adapted to receive. a keyvl0. At one end of the bar 6 a gate .11 is provided.piv-- otally attached thereto and t0 the other end. of said bar 63a gate 12 is also pivotally attached, each gate being attached by, bolts, and

nuts

13, 13, which may be providedjwith

washers

14,1 1 as shownplainlyiin Fig. 3.

The

gates

11, 12, are providedwith guide;

pieces

15, 15, adapted to be adjusted to and: securely held in place. on the side-

pieces

1, 2, by bolts or pins 16, .16 as also clearly shown. in.Fig., 3, and these

guides

15, 15 may be secured at desired positions in the chutes.75 on the sides of the slideways, through

suitable holes

17, 17, provided. therein,- as clearly shown in Fig. 2.. The interior. end of thev shaft, 5 is provided. with a: clutch 9 corresponding to the clutch 9, and, adapted to be loeked'thereto by the key 10, for operating both working beamssimul taneo-usly; the exterior end of'theshaft 5' in slideway C,,rotates inn support Land. terminates in n squared or hexagonal p 0r tion, adapted to take onthehandle 18; such angular portion terminating in. a reduced threaded part adapted to receive anut 19,, which is adapted to. secure the, handle. in; place.

On the side of the slideway Cfa. support. 20,,elearly shown in Fig, 1 is provided. i111 which

holes

21, 21, are made, which. eorrespond.to holes .in the handle 18,-,through which pins or bolts may be=insertedt0 hold' 95 the handle in any desired ,ppsition, when ;it.is..

desired to fix it in place. The

gates

11, 12, are so adjusted to the

beams

6, 6, that when one of said gates is down and resting against the floor of the slideway, the other of such gates will be elevated, leaving the slideway at that part open. I j

The chute is tobe placed in position at a suitable angle asshown in Figs. 1 and 7, the upper part resting against an elevated place, such as a ceiling or other part, from which the material is to be discharged into the chute, and such place is so arranged by a suitable partition or division 40, that the materialentering one of the slideways will be separate from the material entering the other slideway, until it reaches the dis- 7 charging end of both. At the. discharging ends of the slideways a suitable hopper 22, is, provided, to receive the materials as they are discharged and lead them to a suitable mixing or other machine provided for their reception.

Inasmuch as the flow of the materials may be unequal, that is the material passing down one slideway may move more rapidly than that passingfldown the other, an additional gate 23, is provided, which has a rod 23 connecting it pivotally to a handle 25,

which handle 25 is pivotally supported on an upright 26, and extends across the chute, so that by means thereof. the gate 23, may bejraised and lowered as desired, to regulate 5 the quantity of material allowed to pass 7 into the slideway. The handle 25, where it impinges against the upright 27 is provided with holes and the upright 27 is provided with corresponding holes, and through these bymeans of a suitable pin or bolt,the gate 23, maybe held at any suitable elevation; Theslideway C is provided witha similar gate 24, having a rod 24? pivotally connectingit to a handle 28, which is pivoted to v the crosspiece 29, and is also provided'with holes corresponding to holes on the other side of the upright 27, and by means of such handlef28, the gate 24, may be raised and lowered, and heldin anyrdesired position by pinsor bolts inserted in the arm 28,

and the holes in the upright 27.

The method of operation is as follows: 1

The chute A is taken to the place where it is intended tobe used, and set up and supported at'the desired angle, the upper end adjusted to an opening in the floor or level above it, and a division or partition as 40, provided, by means of which the material to be forwarded and measured through one slideway will be kept separated from an- 7 other, untilthe quantity in-each slideway has been properly measured. The lower end of the chuteiis placed at a convenient point to lead the. materials into a hopper 22, connected with a mixing or other receptacle.- I The attendant will first note whether thev capacity between the

gates

11, 12, in each I ducethe desired results.

for instance, adjusting one slideway to take 7 in, say a yard,'and the other to take in one-half, or other proportion of a yard, be-

tween the

gates

11, 12. He will then raise, the gates23, 24, and allow the desired quan-.

tity to run into each slideway'turning the handle 18 to raise the upper or

recelving gates

12,12. He will then note whether the 'material in both slideways is moving at the same pace, and if it is he will commence 'operations,but if he finds that the material in one slideway is moving more rapidly than 7 required, he will adjust the gates 24, at such elevation as will allow thedeslred flow, pinning the same in position on the uprlght 27 by means of the

handles

25, 28, by which the gates are held in position to allow the flow ofmaterial into each slideway at the proper speed.

As it may sometimes happen that the flow of the 'materials orsome of them is so r rapid in one or both of the slideways'as to overflow the lower end of the same, covers 30, 30, are provided, which are to be laid across the top edges of the slideways and held in place by

rods

31, 31, passin through hasps 32, 32. Of course it will e understood that if desired the entire slidewaysi from end to end may be provided with such covers as 30, 30, laid across the top with recesses cut in them for adjustment to the portions projecting from the sides of the slideways, so that open, or partly open, or

entirely closed slideways may be employed.

In Figs. land 2 the two slideways shown are of equal width and depth, and the

gates

11,12, shown in the drawings are of equal distances apart in both slideways," and for some purposes that arrangement may pro- But in case it is desired to send a smaller quantity through one slideway than through the other, and.

the proportions cannot conveniently be reached by means of regulating the posltion of the gateson the

bars

6, 6, another means of decreasing the quantity of material passing through one of the slideways is provided, which consists of a suitable extra strip or piece 34, which may be secured by means of bolts and nuts 35, to one side of one of the.

slideways-to narrow. the same, and decrease 1ts capacity. l

As it may be desired at timesto pass mas terial through the slideways which cannot be retarded very well by, the spadelike motion of the. gates 12, 12', such for instanceqa's broken stone, I show a modifica-,, 3

devices by substitutingfor the sliding gates ,11, 12, hinged or

PIVOlBd gates

tached to working beam-=6; as clearly. shown in Figs. 5 and.6c; theoperation being,.thati when pivoted gates 36 are lying upon the floorr'of the slideway thematerial is allowed to pass over them and impinge against the pivoted'gate 36-=whiehis elevated, and when that is lowered, the flow at the other end of the beam 6, is cut off by raising the pivoted ate.

While I have shown in these drawings and by the description of my invention, an arrangement of a chute consisting of two slideways, it will be obvious that several slideways may be prepared and bolted together, and the outer end of the shaft 5, suitably extended, and provided with bearing supports, and attachments to added working beams, similar to 6, 6, as may be desired. When only one such additional slideway is to be added, the shaft 5 would terminate, as shown in Fig. 2, resting upon the outer edge of the added slideway; but if two slideways should be added the arrangement shown for the clutches could be repeated upon the continued shaft 5, so that slideways three, or four, etc., could be used ton-ether or separately with two slideways as shown in Fig. 2. Gates similar to the

gates

23, 24, with their pivoted handles and stopping devices could of course be provided a so by suitable uprights and a cross beam, without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
