FEED-WATER ADJUSTMENT FOR PUMPS.
SPECIFICATION forming part of LettersPatent No. 273,276, dated March 6, 1883. Application filed November 17, 1882. (N model.)
To all whom it may concern:
Be it known that I, NELs W. HAWKINSON, a citizenbf the United States, residing at Litchfield, in the county of Meeker and State of Minnesota, have invented a new and Improved Feed-Water Adjustment for Pumps, of which the following is a specification.
With the adjusting devices or means heretot'ore employed for regulating the supply of feed-water to boilers difficulty is experienced from the oblique relationlwhich the connectin adestructive explosion, my invention enables me to compensate for the throwing of the connecting rod or rods out of a proper working range with the center of the cylinders of the pump, which invention Ishall hereinafter describe and claim, and the same being represented in the annexed drawings.
A pump provided with my invention can always be kept in motion, supplied with as much water as it will take, can be adjusted so that it will force as much water as is necessary into the boiler, and while this is so the connections can be ad 'usted so as to work without such strains as will render them liable to get out of order as quickly as when the ordi- I Fig. 3 is a vertical section in the line yy of Figs. 1 and 2, and Fig. 4 is a vertical section in the line 20 w of Figs. 1 and 2.
Theinvention represented is intended mainly to provide means for adjusting the stroke of the pump for feeding water into the boiler or other vessel where more or less water is to be used; and the means which 1 shall now specifically describe will admit of the pump being set from a very long stroke to a very short one while in motion, and the same may be connected in a suitable manner between the pump and power to drive the pump, such power being either steam, a common crank, or a belt.
A .in Fig. l is a rod which will be connected 'with the pump, and B a rod which will be connected with the power to drive the pump.
O is a lever; D, an adjustable box fitted in an oblong slot, a, of the lever, and adjusted from one end of the slot to the other by means of a hand-wheel, E, toothed pinion 1) inside the box, and a toothed rack-bar, c, on one side of and below the top surface of the slotted lever G, as shown.
F is a set-screw to fasten the box-D, so that it shall remain firm and stationary after the desired adjustment has been eli'ected. The box D is provided with an upper nut, d,'and a lower nut, d, forming a bottom flange, the nut 01 bearing upon the top of the box and thelever, while the nut d bears against the under side of ward,in the slot at of the lever G, and then by' turning up the screw in a reverse direction the clamping action will again be restored.
Any other well known equivalent mode of loosening and tightening the box D may be adopted without departing from my invention.
The lever G is marked off with a scale, as indicated at g, and the box D can be moved to and clamped at any one of the scale-marks, as
circumstances may require. In the drawings, Fig. 1, the box D is shown clamped about the center of the length of the lever. Below or behind the lever U and box D is a frame, G, with an oblong slot, g, and provided with an adjusting hand-wheel, H, and screw H, said box being fastened to a bracket or a suitable bed-piece, as illustrated at J. In the slot 9 of the frame G the fulcrum or wrist pin I for the lever is fitted by means of a halfbearing, 9 on an extension of the box D, and another half-bearing, g fastened to the halfbearing of the box D by means of screws m, as shown. This wrist or fulcrum pin I is formed with a flange-collar, n, which bears upon the upper surface of frame G and under surface of lever (J, as shown in Fig. 3. A set or clamping screw. K, passes down through the wrist-pin I and half-bearings 9 g and enters the stem of a flanged nut, 12, as shown. The adjusting hand-screw H passes through the flanged nut 2 just below the screw-thread, and by turning the hand-wheel H, and thereby screw H, the lever C, connecting-rods A and B, box D, and wrist or fulcrum pin 1 can be adjusted upon the frame G so that the connecting-rods A and B shall be in proper working range with the piston of the pump, notwithstanding the fact that one arm of the lever 0 is adjusted to havea much longer leverage than the other arm. In Fig. 1 this adjustment of the parts is clearly illustrated, and from the same will be fully understood. By
means of the set or clamping screw K the fulcrum or wrist pin 1 can be slackened for adjustment, and then clamped so as to be firm and steady, and by means of the scale g and a suitable pointer the length of stroke obtained by any adjustment will be indicated.
The indicator may be attached to the sliding 40 justable independently of the frame G and the wrist-pin or fulcrum on which it vibrates, and then is adjustable with the wrist-pin, substantially as and for the purpose described.
2. The combination of the lever (1, provided with a toothed rack and connecting-rods, with the clamping-box D, provided with apinion, and witha wrist-pin applied to an adjustable clam ping-nut, substantially as and for the purpose described.
32 The combination of the slotted frame provided with the hand-screw H, the sliding wrist-pin I, the adjustable clampingbox D, with the lever C and its connecting-rods, substantially as and for the purpose described.
4. The combination of the hand-wheel E, block d, and nut d with the box D and lever G, substantially as and for the purpose described.
5. The combination of the flanged wrist-pin I, half-bearings g g, and box D with the lever 0, frame G, and set-screw K, substantially as and for the purpose described.
