My invention relates to improvements in pumps and although the invention is of wide application, it has particular adaptation for use in connection with a wind driven motor.
For purposes of illustration I have shown and will describe my invention as applied for use in the pumping of bilge water from boats. One of the problems of boat owners and users is the accumulation of bilge water and a suitable means i for ejecting the same. By the use of my invention a very inexpensive and practical means of eliminating this water either during active or inactive periods of a boat is provided.
One of the principal objects of my invention .5. lies in the provision of a means whereby the air driven motor and pump may be conveniently set up for operation and as conveniently taken down for storage out of the way when not in use. My invention is particularly useful for op- 20 eration during periods when the boat is moored, as at night, and may be easily taken down and stored out of the way during the daytime or when the boat is being used.
One important feature of my invention lies in the provision of means whereby the deck surface upon which the pump device is mounted during operation is unencumbered when the device is taken down and stored.
Another object of my invention lies in the pro- 30 vision of r a novel pump means for the sucking of bilge water and the ejection thereof.
Still another object of my invention, and an important feature, lies in the provision of a wind driven motor which upon reaching a predeter- 35 mined speed of operation automatically folds up and stops, thus eliminating the excessive .wear' on the mechanism incident to too high a speed of operation.
Another object of my invention lies in the 40 provision of a novel mounting means for pumps,
particularly in cooperation with a boat.
Although my invention is herein shown and described in connection with the pumping of water, it will be obvious that the same is applica- 45 ble for other purposes as well, such as the compression of air or liquids.
Other objects and advantages will be apparent as the description proceeds, reference now being had to the figures of the accompanying 50 drawings forming a part of this application and wherein like reference numerals indicate like parts.

The reference numeral I refers generally to a boat and is illustrative only. The boat is shown as moored to a buoy 2 at which it swings with the wind. It is often desirable in the use of boats, particularly pleasure craft, to utilize the mooring period, generally at night. during which to eject the bilge water and in order that this may be done with a minimum of efiort and expense, I have provided this pump with a wind 40 driven motor which may be readily set up for operation and which may be as, easily taken down and stored out of the way during the use of the boat and particularly when the entire deck surface is to'be preferably kept clear. 5
With reference to Figure 7, the reference character 3 refers to the deck of the boat, or any other supporting surface through which there is provided an opening 4 adapted to receive a flanged socket member 5, the flanges 6 of which extend 5 downwardly through the opening 4. On the underside of the deck 3 there is provided a hollow tubular casing I provided with a flange 8 adapted to engage against the underside of the deck and with an upwardly extending end portion 9 adapted to fit within the socket 5. The socket member 5 and the casing l are secured rigidly together by means of screws ll! or the like which pass through the flanges of the socket 5 and the casing I and through the deck 3. The socket member 5 is relatively flat and thin on the upper surface of the deck whereby no substantial obstruction is provided on the deck surface thereby. A plug H (see Figures 4 and 6) is provided for removable mounting within the socket opening whereby to close the same. The head l2 of this plug overlies the flange of the socket member 5 and is provided with a pivoted bail l3 whereby the same may be readily lifted out to permit the pump member to pass through the socket opening into the casing l. A groove M is provided in the top surface of the plug l2 to receive the bail l3 whereby to further reduce the deck obstruction.
Referring againto ,Figure '7, the lower end of the casing l is reduced in size to provide the nipple l5 adapted to receive one end of a hose E5 of any desired length and preferably flexible in character. The free end of the hose I6 is provided with a thimble H (see Figures 10 and 11) to which the end of the hose is securely attached. The thimble I! is provided at its end with a flanged cap l8 adapted to hold in position over the end of the thimble a perforated plate or screen l9 serving as a strainer.
The lower or intake end of the casing 7 at its point of size reduction is formed as at 20 as a valve seat to receive a loose ball valve 2!.
Adjacent the upper end of the casing l at a point below the deck 3, one side of the casing is provided with a laterally extending exhaust nipple 22 adapted to receive one end of an exhaust hose 23 preferably flexible in character and which may be carried through an opening 2'2 (see Figure 1) in the side of the boat or to any other desired point of exhaust.
The casing l is also provided at one point with a hollow boss 25 internally threaded to receive a threaded set screw 25, the outer end of which is r provided with a finger piece 21 and the inner end of which is preferably pointed as at 28. he inner end of the set screw is free of threads and is adapted to extend centrally across the hollow casing 1.
The pump mechanism includes an elongated tubular casing 29, the lower end of which is adapted to engage in the socket member 5 and extend downwardly therethrough into the casing 1 with a relatively close sliding fit therewith and adapted for ready insertion therein and removal therefrom. The lower end of the casing 29 is provided at one point with a notch 30, adapted to engage over the inner end of the set screw 25 within the casing i and upon which the tubular housing 29 is supported. This is shown clearly in Figures 5, '7 and 9. It is obvious that with the housing 29 in such position and the set screw 26 tightened, the pointed end thereof will engage against the inner surface of the housing 29 and bind it tightly Within the casing 'i'. It may be stated here that the positioning of the set screw 26 and the notch 39 is such that when the device is so positioned and locked, the wind motor is in position facing the bow of the boat and therefore, always into the Wind when the boat is moored, as well as in position to receive any breeze caused by the travel of the boat when the device is set up for operating during the movement of the boat.
The housing 29 is provided with an opening 3! which, when the housing is in its operating position just described, aligns with the hollow exhaust nipple 22 and hose 23. Slidably mounted within the tubular housing 29 is a rod 32 adapted for reciprocation therein. The lower end of the rod is threaded as at 33 (see Figure 5) to receive the threaded upper end of a hollow piston 3! which may be secured in adjusted position on the rod by means of the lock nut 35. The lower end of the piston 34 is provided with a slightly enlarged head 36 having a close sliding fit within the casing 29 and this head is provided with a suitable packing ring 31 of any desired type to provide an effective flexible seal between the piston head and the walls of the housing 29.
The head 35 is provided with a port 38 extending vertically therethrough and the upper end of which is formed as a valve seat 39 to receive the ball valve 40.
The piston 34 is provided at one point in its side wall with an opening M. It will be noted that there is a space lift between the piston 34 and the inner walls of the housing 29 and this opening ii provides a port between such space and theinterior of the hollow piston 34. From the foregoing it will be clear that upon the reciprocation of the rod 32 and piston 34 within the housing 29, the following action will take place. Assuming the intake hose It to be immersed in water, as in the bilge of the boat, the upward stroke of the piston 34 will result in sucking water inwardly through the screen t9, the hose l6, past the ball valve 2| and into the end of the housing I and casing 29 below the piston 34. Upon the downward stroke of the piston, the pressure will hold the ball valve 2! on its seat 2! and cause the water thus trapped below the piston to pass upwardly through the port 38 in the piston head past the ball valve 50 into the piston above such ball valve and out through the port 4! into the space between the piston and the inner wall of the housing 29. On the next upward stroke of the piston the same intake or suction action is effected and at the same time the water above the piston head is ejected outwardly through the hollow nipple 22 and exhaust hose 23. Obviously this cycle of operation continues so long as the piston is reciprocated within the housing 29.
The upper end of the housing 29 is slotted longitudinally as at 42 and the rod 32 at its upper end adjacent this slot 42 is provided with a head 43 to which is attached one end of a screw 44 extending outwardly through the slot 42 and pivotally receiving one end of a link 55, the opposite end of which is pivotally secured to a screw 46 eccentrically mounted upon a r0- tatable hub 31. This hub M is suitably secured upon one end of a shaft 48 rotatably journaled upon the upper end of the housing 29 as by the short horizontal bearing member 48 shown in Figure 1. The opposite end of the shaft 18 is provided with a collar 59 (see Figure 3) against which are mounted upon the end of the shaft 48 the hub ends 5! of a plurality of blades 52 comprising the air foils or wind driven motor.
Spring washers 53 are provided between the hubs 54 of the blades and lock nuts 54 are provided on the extreme end of the shaft 48 whereby the tension on the inner ends of the blades may be regulated and adjusted to the desired amount. While it is intended that the blades 52 shall rotate with the shaft 48, as a matter of fact providing the rotating force for such shaft, it is also intended that the blades shall be rotatable on the shaft to and from the unfolded and folded positions respectively shown in Figures '7 and 8. While any desired number of blades maybe provided, four have been shown for illustrative purposes and in order that when unfolded to wind receiving position as shown in Figure 7, they are spaced equi-distant apart to provide for a maximum wind resistance. Certain of the blades 52 are provided adjacent their hubs with shoulders 55 (see Figures 2 and 3), and certain other of the blades are provided adjacent their hubs with ears 56 adapted to engage suchshoulders when the blades are in unfolded position, limiting the movement of all the blades in one direction and in such positions as to provide for the equal spacing thereof as in Figure 1. It will be understood that the blades 52 are double blades extending on opposite sides of their hub portions. When the blades are moved to the folded position shown in Figures 3 and 8, the ears 55 engage against the edge of the adjacent blade whereby to limit the folding movement thereof and provide for the alignment of the blades.
One of the blades is provided with a weight 5 (see Figure '7) which serves a twofold purpose, firstly, a means for holding this particular blade while the other blades are moved to open position. Secondly, this weight acts, upon a certain predetermined speed of rotation of the shaft 48 and blades, to unbalance the equally spaced position of the blades and to cause them to automatically fold to the position shown in Figure 8 by virtue of the blade carrying the weight moving on the shaft 48 to bring the ear 56 thereon into engagement with the shoulder 55 of the adjacent blade, this in turn moving until the ear thereon engages the next shoulder and so on until the blades have folded up. The purpose of this arrangement is to prevent the motor being driven at too high a rate of speed which would result in excessive wear on the pump. Obviously when the blades are folded together there is but sufncien't wind resistance surface presented to cause but very slow rotation of the motor, if any. The speed of rotation at which the weight 5'! will cause the automatic folding of the blade, depends upon the size of the weight 57 and upon the tension provided between the blades at their hub portions on the shaft 48.
Obviously upon rotation of the shaft 48 in this manner, the hub ll thereon will rotate causing the eccentrically pivoted link 45 to reciprocate the rod 32 and pump piston 34.
In practical operation and assuming the housing 29 and motor to be disengaged from the housing 1 and the plug and cap H-l2 in position on the deck, the pump can be quickly set up for operation by merely removing the closure cap and inserting the end of the housing 29 into-the socket into engagement with the screw member 26 whereupon the device is ready to operate. If the motor and pump are to be left in this operating position any great length of time the set screw 2? can be tightened to clamp it securely in position, access being provided to the screw in any suitable manner. If the operation is to be for a short period only, it is unnecessary to tighten the set screw 25 as the motor is held against turning in the socket by means of the notch 39 engaging over the screw 26.
When it is desired to stop the operation of the pump, the housing 29 can be merely lifted out of the socket and stored away in any convenient I out of the way place, the plug 1 I being placed in the socket 5 leaving the deck practically unobstructed.
In Figures 12, 13 and 14 I have shown a slightly modified form ofmotor drive and fasten- In this form the socket member 5a.,
ing means. corresponding to socket 5, is suitably secured in an opening through the deck 3a and is provided on its upper side with a threaded socket to. Adapted for engagement therein is a hollow exteriorly threaded sleeve 6b. The socket member is internally shouldered as at 60 to receive rubher or other resilient gasket rings 6d against which the lower end of the sleeve 6b engages when screwed into position.
Extending into the lower open end of the socket .50. and suitably secured thereto as by soldering or welding, is one end of the intake pipe lfia, the opposite end of which is provided with the strainer lila.
The upper end of the sleeve to is provided with to which is connected the exhaust pipe 23w. In
this form, the pump piston, valves, etc. are mounted in the housing 291) in the same manner as previously described, except that the exhaust port is positioned above the deck 3a. The function and operation of the pump members are identical.
Threaded upon the threaded portion 29a of the housing and just above the hand wheel 6c, is a lock nut ring 69, its outer periphery being indented or recessed. Obviously, with the lock ring by tightened down against the upper side of the hand Wheel 66, said hand wheel cannot be turned to remove the sleeve from the socket because such sleeve is internally threaded on the portion 29a of the housing. The locking ring 69 must first be loosened by screwing it upwardly before the sleeve can be unscrewed from the socket, and thus permit removal of the housing and motor for storage The threads 29a and 6b are of opposite pitch, i. e. one is a right hand thread and the other a left hand thread.
In order to prevent unauthorized or surreptitious removal of the device, a padlock 6h may have its locking loop passed through one of the openings (if and extending into one of the indentations on the lock wheel 6e, thus preventing turning of such lock wheel without removing the padlock.
In this form of the device, the pump rod 320. has its upper end pivotally secured eccentrically, as at 46a, to a gear 41a suitably journaled on a pintle i'lb. Meshing with the teeth of this gear is a pinion 41c mounted upon a stub shaft 47d rotatable by the blades 52a of the wind motor. The operation of this device to reciprocate the pump'rod is the same as previously explained.
I wish to again make it clear that although this device has been shown and described specifically in connection with a bilge pump, it is obvious that it is adaptablefor other purposes and in other combinations. Also changes may be made in details of construction and arrangement of parts without departing from the spirit and scope of my invention. I do not limit myself, therefore, to the form herein shown and de scribed other than by the appended claims.
