Specification of Letters Patent.

Application filed March 15, 1912. Serial No. 684,048.

To all whom it may concern:

Be it known that 1, WILLIAM VAN DEN HEUvEL,.a subject of the Queen of the Netherlands, (who has declared his intention of becoming a citizen of the United States,) resident of Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sluice-Gates, of which the following is a specification.

- My invention relates to water gates and has particular reference to the construction of a flexible curtain gate for use in connection with sluices. V I

In many parts of the country where irrigation is necessary, also where water is conducted through sluices for other purposes, it is customary to have gates for closing the sluice and diverting or withholding the supply of water. Such gates are usually built of heavy, cumbersome planks in order to give requisite stiffness. It is apparentthat when closed the whole weight of water isagainst the gate makingits movement in opening or closing a matter of very great difficulty. In fact, heavy or ponderous machinery is often required to move a .gate of adequate size.

My improvement proceeds upon the theory that a gate of equal strength and rigidity may be secured by forming the same from a plurality of sections hinged at their longitudinal edges and so arranged that in opening or closing only one section at a time is displaced, that is, in the preferable construction one end of the curtain is secured to suit-able framework and the other end to a bodily movable drum. Desiring to open the gate the drum is caused to rotate thus displacing one section and allowing water to pass through the corresponding opening. The action of the water in passing through the opening will then .tend to assist the rolling action of the drum, successively displacing sections of the gate until the entire opening or any desired part thereof is clear. Desiring to close the sluice, the rotation of thedrum is reversed and the curtain unrolled until the opening is closed.

I am aware that sectional gates have heretofore been employed but believe I am the first to provide a sectional gate which may be rolled on a drum as hereafter described.

The objects of my invention may be stated as follows: 1st, to reduce the power necessary to open and close sluice gates, this result being accomplished by forming a gate of a plurality of sections hinged together on their longitudinal edges; 2nd, to employ in connection with the hinged sections a drum together with means for rotating the drum in order to roll and unroll the gate thereon and therefrom; 3rd, to form the sections from a plurality of units of predetermined sizes to the end that a gate of any desired width and length may be built without the construction of special parts, and, 4th, to arrange a packing strip in the joints between the sections whereby if desired all water may be prevented from passing through the gate.

My invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is a front elevation of a gate constructed in accordance with my invention; Fig. 2 is a side elevation of the same; Fig. 3 is an enlarged front elevation of a plurality of sections; Fig. 4 is a fragmentary enlarged sectional view of the ends of the three sections showing the means for hinging the same; Fig. 5 is a section on the line 5- 5 of Fig. 4; Fig. 6 is an enlarged fragmentary detail showing the means for uniting separate units to form a section, and Fig. 7 shows a gate rolled on a drum and in the positions as shown in Figs. 1 and 2.

Referring more particularly to the drawings, it will be seen that in a sluice 10 is mounted a frame composed of a plurality of vertical supports 11, having a bottom connecting member 12 and a top member 13. To the top member 18 is secured one end 14 of my novel curtain gate. This is composed of a plurality of sections adapted to be wound upon a drum 15, carried by a shaft 16, having sprockets 17 upon the ends thereof. Also mounted on the shaft 16 are vertically extending spacers 18, which spacers are divided or split throughout their middle portions, carrying on their upper ends idlers 19. Chains 20 pass over the sprockets 17 and idlers 19, and around sprockets 21, keyed to a shaft 22, having a worm gear 23 thereon. Motion is imparted to the gear 23 by means of a worm 24, connected to any suitable source of power. The spacers 18 are guided by the shaft 22, said shaft passing between the split or divided parts of said members. Rollers 25 serve to maintain the chain 20 in contact with the sprocket 21 on one side and'similar rollers 26 maintain the chain away from the sprocket on the opposite side.

It will be seen that the drum .15 may be caused to rotate by movement of the chain and that upon said movement the curtain be rolled or unro-lled as desired, due to the fact that the upper end 14 of the curtain is attached to the frame.

Referring now to Figs. 3 to 6 inclusive, it will be seen that I contemplate forming my curtain gate from a plurality of sections hinged on their longitudinal edges, each of these sections being formed from a plurality of units, the units being bolted together at their ends. Each of these units as shown, is formed of cast metal having a web 27, outwardly projecting end flanges 28, provided with bolt openings and side flanges 29. It will be understood that the units are duplicates and that a description of one is sufiicient. On the edges of the units are formed hinge projections 80, perforated as required to accommodate a shaft 31, extending preferably through the entire length of the gate. This shaft may be keyed to one of the units as at 33, although this will not be found essential. Between the hinge lugs 30, I prefer to insert a hollow filler 32, as best shown in Fig. 4, although it will be understood this member may be cast as a part of one of the units if desired.

In some constructions it may be found desirable to form an absolutely tight joint and in such cases I provide just back of the hinged joints an arc-shaped opening 34, within which is mounted a packing strip 35, formed preferably of bronze or similar ma: terial. This strip is shaped on a radius drawn from the center of the shaft 31, and thus permits the rotation of the united sections as required in order to roll upon the drum 15. The water tending to leak past this strip will cause the strip to be pressed agaisnt the face of the arc-shaped opening. In Fig. 5 I have shown the strip 35 as being cut away to permit the rotation of the keys 33 with one of the sections. I prefer to con- I struct the units just described in a certain definite length to the end that a builder may combine as many of these units as necessary in order to form a complete gate. It will also be found much easier to-cast or shape the units in smaller sizes. The ends of the units, as shown in Fig. 6, are offset or required and which moreover may be operated with ease as comparedto-the operation of a heavy, rigid gate.

It is obvious that while I have described the section as being composed of cast units, they may be pressed or rolled if desired. It is further obvious that the particular form and construction of the units composing the sections may be varied; also that the construction of the operating means for the gate may be modified to suit difierent conditions of service. For instance in th'e construction shown, where the curtain is attached at its top, the operating means are efficient, whereas, if the gate be attached at its lower end, a different form of operating means may be found preferable. Other and further modifications may be made all with out departure from the spirit of my invention.
