' rinse BERT ID. GILSON, OF CHICAGQ, ILLINOIS.
CIRCULATION-PUMP Application filed. October 4, 1920. Serial No. 414,609.
Be it known that T, BERT D. (insert, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Circulation-Pump Attachments, of which the following is a specification.
This invention relates to an internal combustion engine, and has particular reference to a water circulating pump for such engine.
in water cooled engines of the type specified it is quite common to place a pump in the cooling circuit for the purpose of accelerating the flow of the cooling medium. Some engines are designed to includesuch pump. Gthers, which are built to sell very cheaply, such as the engine of a Ford automobile, are not provided with such pump, but pumps are specially built for attachment to the latter type of engine, and the present invention is directed to a device for the engine of a Ford automobile. The problem of providing an efficient pump, attachable within the very limited space under the hood of such automobile, has been successfully solved, but it has heretofore been found quite di'llicult to provide attachable devices for aligning such pump to be driven by suitable rotating members of the engine.
With these conditions in view my inven tion consists in devices whereby the attachment of such pump is greatly facilitated, and a more perfect driving connection obtained. More specifically my object is the provision of a bridge, attachable with the pump and carrying all elements required in order to properly connect the pump to be driven from the engine. These objects and the further advantageous features of the invention are hereinafter fully described, and structures embodying'the invention are illustrated in the appended drawing, of which:
Fig. 1 is a side elevation of an engine of the type referred to,'and pump and pump connections are shown attached to the engine.
Fig. 2 is a plan view substantially in agreement with'Fig. 1, and
Fig. 3 is a similar View illustrating additional features of the invention.
The numeral 1 denotes the engine water jacket, from which extend connections 2 to the top of the engine radiator (not shown). From the bottom of said radiator rises diagonally a tube 3, whose upper end is clamped on the inlet duct P of a circula tion accelerating pump 4:, through which the cooling. medium returns to the water jacket, all as usual in practice. Said pump has a bearing 49 for a drive shaft 5, and the latter connects with an extension G carrying'at its outer end a pulley 7 said pulley in turn aligned to be driven from a suitable source. In the'drawing a belt 9 is shown bent over the said pulley, over a pulley 16 of the fan shaft, and over a pulley 8 mounted on the engine crank shaft 8, but other driving connections may be provided to suit circumstances.
The pump is secured to the side of the waterjacket by means of a pair of bolts 10, 11, said bolts seated in the perforations provided in the engine for supporting the usual inlet elbow of the tube 3, which elbow is first removed from its fastening and de tached from said tube, whereupon the pump is attached, as specified. Between the base 4 of the pump, and the boss 1 of the water jacket is inserted the foot 12 of a bridge 12, and the latter extends sidewise to the front of the engine, in order to support the front end of the shaft 6. Such supporting means may conveniently take the shape of a bearing'box 13, in which the shaft 6 is rotatable, and which is provided with an integral stud 13 said stud projecting inwardly and seated in an elongatedperforation 12 of said bridge. Suitable elements, such as a threadednut 15 and a clamping washer let engage said stud and serve to retain said bearing box firmly in aligned position.
Attention is directed to the shape of the bridge 12. It extends sidewise substantially in a' straight line for about two thirds of its length, whereupon it makes an outward turn in order to bring the end portion supporting box 13 close to the center line of the pump shaft 5, 6. A boss 12 is pro vided on the inner wall of the bridge, at the beginning of its outward turn, which boss bears against the side of the water jacket 1 and thereby serves to keep the bridge steady. It is also noticed that said bridge is made with a wide flange 12, which materially strengthens thestructure. T
The advantages of the structure described are readily appreciated by those versed in the art. The pump is shipped to the purchaser ready to attach with the two screws 10, 11, which simultaneously clamp the material, such as leather.
7 ment.
7 Referring now to Fig. 3, I shall now describe means for further aligning the shafts. 7 The distance from the surface of the water jacket boss 1 and to the spot against which the bridge boss bears may'vary slightly, due to the fact that no-twoca'stings are exactly alike, and such variation may suflice to throw the two bearings out of line. order to correct such dislocation thebox 20 is movable out and in, and for this purpose it is seated in an eccentric'sleeve 21 and clamped in position by a nut 22. Said sleeve is provided with external screw threads engaging a threaded perforation of the bridge '23, and a slight turn of said sleeve suffices to'advance or retract the box 20 sufficiently to correct the error of align- Furthermore there isa small'amount of play between the bolts 10, 11 and the perforations which said bolts engage, sufficient to tilt the'pump slightly at the time of mounting the pump and bridge, and thereby to throw the two shafts out of align-' ment in a vertical plane. In such case the nut 22 is again loosened and the sleeve rotated a slight amount, thereby raising or lowering the box as much as required, and
j as said box is, free to turn in the sleeve,
it is obvious that the shafts may be quickly realigned, whereupon the nut 22 again is tightened.
Occasionally an engine casting may be found soimpefrfect that the boss 23 does not reach said casting at all, in which case .the pull of the belt will tendto put a strain on thebridge, which strainfiin turn may operate to throw theshafts out of align -ment. For this purpose I introduce means 'foradjustingsaid boss 23, and such means I may conveniently take the'shapeof a setscrew 25, seated in said boss and locked in adjusted position by a threaded nut 26.
The'devices described above may be attached toan automobile engine of the type mentioned by the purchaser without any special tools except the wrench-which 'always accompanies an automobile. When clamped in position, 'by'the two bolts mentioned, it will work satisfactorily on'account of the flexibility of'the joint in: the shaft, and vif more perfect alignment is desired by the user,'he may readily obtain such in the manner indicated. In conclusion I wish to call attention toone more feature of my invention. A beltwill stretch, and the belt 9 may become so slack that it will not drive the pump at full speed,
and for this reason-I have introduced means for maintaining said belt taut. It is noticed 1. by referring agaln to h 1g. 3, that the bridge 23 is made in two parts joined together by a hinge pm 27. lfa slight slackness occurs,
of alignment; Of course, if suchreadjus'tment is repeatedly performed, it will also" become necessary to readjust the front bearing of said shaft A strong spring 28 may purpose of t a conveniently be added for the maintaining said belt taut.
