speeinqauon fbrmingpafrof naam-Patent N0.f 1` 7{1,692,' datedMamh r4', 1876, application fnac L To all whom it may concern: v l' Be it known that I, AMOSv MALLORYQf 'y Mystic Bridge, New London county, Connectiv cut,have invented certainy new and useful Improvements Relating to Tide-Mills yor Tide! Water Power, of which the -following is a` specification: n y
My invention renders practicable the utill izing the power of the tides continuously-an opposite condition is obtained, and the lowreservoir is filled to a half or some other fraction of its capacity. I esteem it impractica- Vble to raise and lower wheels, and ponderous connected parts; but my wheels do not feel backwater, and utilize an immense flow of water, under a low head, with peculiar advantage, and make the two levels pf the water practically available. A
The'accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention. 4
Figure l is atop view of my tide-mill.' Fig. 2 isa horizontal section through a part of the cross-dam.
Similar letters of reference indicate like parts in all the figures.
A is the dry land; B, the water, subject to full force of the tidal influence, rising and sinking to the extent of whatever tides may obtain in that local-ity.v C is the dam, dividing the bay from the tide-water B 5 and D is is the cross-dam, dividing the bay into two parts,'E F. The mill M is furnished with peculiar means to utilize a small head of water, as will presently be explained. At and near high tide, the water from the ocean B llows freely into the basin E through valves c in the dam O. At and near low tide, the water runs out freely from the basin F through the valves j'. Thus conditioned, the water in the basin F is always considerably lower than the water in the basin The liability of thewater to stand at various levels in this system involves a difficulty, which IY have met by peculiarly-adapted hydraulic machinery. Through Vthe'mill vM extends a long horizontal shaft,
preferably of hard brass, inone continuous piece or formed of suitable lengths, strongly coupledv together to resist a tensile'strain. On this shaft, which may be of small diame` ter, ar'e mounteda considerable number of small screw-propellers. These should be also of brass, or the whole may, if preferred, be'of wrought-iron or steel thoroughly coated with brasszinc, or other protector, and hushed with brass at the bearings. The screw-pro- .pellers are in two sets. One set, G, is righthanded 5 the other set, H, composed of an exactly equal number, of equal size, and of corresponding form, is left-handed. Curved pen-stocks I, formed of masonry or other suit-` able material, receive the water from the highlevel reservoir or pond E,'and discharge it into the low-level reservoir or pond F. J J are peculiar gates, analogous io butteryvalves, operated by a single rod, K, controlled by the attendant at the mill. Each gate J is slightly twisted, for a purpose which will presently appear.- The gates J being properly adjusted, by their opening and closing give greater or less .freedom to the How of the water. In the best condition of the apparatus the valves J stand wide open, and the water is allowed to ow freely, except that it is given a slight helical motion by flowing past the twisted gates J In passing the screw-pro# peller, the current of water imparts a rapid rotatory motion thereto, and receives from the inclined position of the blades of the screwpropeller a tendency to a helical motion in the direction opposite to that of the rotation of the screw. This, in the best condition of t the apparatus, is only just sufficient to neutralize the effect of the helical motion in the other direction, which itmreceived in passing the gate J, and the water is consequently discharged into the lower pond F without any considerable twisting motion. It simply llows out in a moderate calm current. Supposing six right-handed propellers, G, and an equal number of left-handed propellers, H, to be employed: The end pull on the six propellers Gr will all conspire to nlovetheshaftfm,in one direction, but it will bere'vniel'nberd that all the propellers H conspire' to pull the shaft m axiallyfin the opposite'direction. lAsuthe` propellers H are equal` in number andsize, and as exactly correspondent inform as pos-1 sible, the pull in the tivodirections 'will "be very nearly balanced. One or more collars on the shaft m, being held nvsllitable,,babjbittv Y screw-propellers G and H asnay be required.:
The works mayA be infcr'eas'ed'or reduced from time totimeby adding ortakin'g avvay one or more from each side. 1
My invention gives a'quick'rotatory'motionl to the shaft m, Whichcan be' 'depended on atr resses.
,au u nesyofv title.` The `gearing of belang frornthis'sbaft "to "the other portions of the nilliay be of any ordinary or suitable char acter. rEhe shaf'tm and its adjuncts should be laid sufficiently low to be nearly or quite immersed undery all vvorking'conditions of the apparatus.` "Suitable'provis'ion should be made to exclude oating masses of Wood or ice. v
y, {Do jfacilitate repairs, the several screw-propellers G and H may be made in halves, and
bolted together around the continuous shaft m.
` Iy claim as m-y inventionf- `m,'in combination with suitable controlling ymeans J K, and dams C D, and automatic valves ef, as and for the purposes herein specited. t Y, l c. In testimonydfvifhereof Ijhafve" hereunto set fmylname in presence of tivos'ubscribing witv, AMOSMALLORY.
