SPECIFICATION forming part of Letters Patent No. 405,079, dated June 11, 1889.

Application filed March 16, 1889- SerialNo. 303,517. (No model.)

To ctZZ whom itmay concern.-

Be it known that I, CLEVELAND J. CHENEY, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in WVater-Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use i wheelsB B adapted to move in a plane par- 3 allel to the face of said gate.

the same.

My present invention has reference to an improvement in flood, sluice, or water gates- 5 such as are used in the forebays of mills,penstocks, or similar water-conduits, and also the gates and valves of Water-pipes, &c.to regulate the discharge of the water, the object being to provide a gate whose manipulation may be more convenient and easy than that z of other ordinary forms now in common use, and whereby the usual excessive friction of sliding bearings in water gates may be j avoided; and the invention consists, essentially, of any ordinary sluice or water gate 1 being firmly bolted thereto.

provided with suitable wheels or rollers and having vertical cam-shafts, whereby the gate may be lifted from its seat, substantially as described; and it furthermore consists in certain peculiarities in the construction, arrangement, and combination of the several mechanical parts, substantially as will be hereinafter described and claimed.

In the accompanying sheets of drawings, illustrating my invention, Figure 1 is a front elevation of myimproved water-gate. Fig. 2 is a side elevation of the same, the gate being shown as resting upon its seat or bearings. Fig. 3 is a similar side elevation showing the gate slightly removed from its seat, so as to be in position to be lifted. Fig. 4 is a horizontal sectional plan view on the line o: 00 of Fig. 1.

Similar letters of reference designate corresponding parts throughout all the different figures of the drawings.

A designates a sluice-gate or water-gate constructed in any ordinary and familiar fashion, of a strength sufficient to withstand the head of water coming from the mill-race or. other water-course, and said gate has its seat or bearing on the sidesDD of the waterway. It is evident that to raise a gate thus I gate are obviated.

The gate A is provided wit-11 two pairs of These wheels are carried on journals 0 O and pro ect horizontally from the castings O, which are securely bolted to the water-gate.

The detailed construction of the journals and castf ings is shown in Fig. 1. supporting the wheels to the usual axles that I prefer this mode of are sometimes employed with gates of this kind. However, I do not desire to be restricted to the axle-journals represented herein, but

reserve the liberty of mounting the wheels in a different way, if desired.

E denotes a start secured to the gate by Braces e 6 may also be employed to connect the start firmly and rigidly to the gate. The start operates the gate by lifting or lowering thesame when power is applied to the upper end of the start.

, It is not thought necessary to illustrate such a power in this case, but simply to show and describe the start.

F F denote two vertical cam shafts suitably held at top and bottom and located 0pf constructed, or in fact any kind of a waterposite the wheels 13, and between them and the sides D D of the water-way, which sides constitute the seat of the gate. These shafts are held at top and bottom in such a manner that they. may be easily capable of rotation.

. They are preferably round in form, so as to have a circular cross-section at top and bottom, where they are held in their bearings, but they are provided throughout a certain portion of their distance with a longitudinal, fiat, or oval face a.

When the gate is resting upon its seat, closed, as shown in Figs. 1, 2, and 4, the wheels 13 B B B will rest in close contact with the flat or oval faces a a of the vertical shafts F F, just clearing the same. If these shafts, however, be rotated and their rounded sides thus brought into contact with the wheels B 13, it is evident that these shafts will act as cam-shafts and that this rotation will cause the wheels B B to be forced outward slightly, and thus, the gate A, to which they are connected, be removed from its seat, so that it will no longer bind thereon, but will be in the position shown in Fig. 3, where it can be easily lifted by the application of power to the start E, all friction which might be caused by the sliding of the gate A upon its seat thus being effectually overcome and avoided. A quarterrer olution of the cam-shafts will be sufficient to bring these shafts up to the full size and lift the gate from its seat and load it onto the wheels.

In Fig. 3 the gate is shown as-entirel'y clear of any contact with the slides or bearings D D, and it is manifest that a lifting-power applied to the start would cause the wheels B B to travel easily up the sides of the shafts F F. By the further rotation of the shafts F F either forward or backward the plain faces a a can again be brought opposite to the wheels B B, and thus the water-gate replaced upon its seat.

G denotes alever-handle or wrench appliedto the square upper end of one of the shafts F, for the purpose of revolving the same in i the manner just described.

I do not wish to be confined to the precise construction and arrangement of the parts of my invention as herein described, but reserve the liberty of varying the same slightly to adapt the construction of the invention to the exigencies of individual cases. The use of the invention may also be varied, as it is adapted for the gates and valves in pipes for conveying water for the supply of cities, towns, &c.

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

scribed.

2. In a water-gate, the vertically-moving gate provided with suitable wheels, in combination with the vertical shafts having longitudinal fiat or oval faces, said shafts being located in contact with the wheels and adapted to be rotated to lift the gate from its seat, substantially as described.

3. The combination of the water-gate provided with suitable wheels and a start attached thereto, the vertical slides which form the seat for the gate, the vertical cam-shafts having longitudinal flat or oval faces a a, said shafts being properly held at top and bottom and located in contact with the wheels, specified, and the devices for rotating said 7 shafts and permitting the gate to be lifted or Elowered, substantially as described.

4. The combination of the water-gate A, having the wheels B B B B, the vertical slides .fon which the gate has a bearing, and the ver- Jtical cam-shafts F F, having longitudinal flat or oval faces a a, substantially as described. 5. The combination of the water-gate A, the icasting O, secured thereto and having journals C, the wheels B, mounted on said journals, and the cam-shafts F F, having flat or oval faces a a, all arranged for joint opera- ;tion, as specified.

6. The combination of the gate A, the casting 0', secured thereto,;having journals 0, the wheels B, mounted on said journals, the start 1 E, secured tothe gate, the slides D D, on which the gate has a bearing, and the cam-shafts F 1 F, having fiat or oval longitudinal faces a a, said shafts being properly held at top andbottom and located in contact with the wheels :3, so that by the rotation of said shafts the gate may be lifted from its seat, substantially I as described.

In testimony whereof I affix my signature in -;presence of two witnesses.
