Specification of Letters Patent.
Application filed. April 4, 1913.
Patented May 112, 1914.. Serial No. 758,911.
T0 (ZZZ (Ii/107)]. it may concern Be it known that I, ARTHUR L. PRIMEAU, a citizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Pump-Operating Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention comprehends improvements in pump operating mechanisms and relates more particularly to those of the type especially adapted for use in connection with fluid measuring pumps,
The primary object of the invention is to provide a pump operating mechanism of this nature, which shall he of extremely sim ple construction, cheap to manufacture, and very accurate and eflicient in operation.
Another and more specific object of the invention resides in the provision of operating mechanism including a rack bar, a tubular guide therefor, a pinion extending through the guide and adapted to mesh with said rack bar, and means for rotating the pinion whereby the rack bar may be reciprocated.
The invention also aims to generally improve pump operating mechanisms to render the same more useful, practical, and commercially desirable.
With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.
For a. complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which,
Figure 1 is a side elevation, the casing and a portion of the operating mechanism being shown in section, Fig. 2 is a front elevation, Fig. 3 is a section taken on the plane of line 33 of Fig. 1, and Fig. 4 is a detail view of the rack bar and guide therefor.
Referring in detail to the drawing by numerals, 5 designates a suitable support of any nature formed with the openings 6 and 7. A casing, generally designated 8, is mounted upon the support 5 and contains my improved operating mechanism. This casing includes a base or bottom plate 9, which is recessed adjacent one end, as indicated at 10, to provide a drip receptacle. Vertical side walls 11, a front wall 12, and a rear wall 13, extend upwardly from the base plate 9, and are secured in position by means of suitable fasteners 14. The front wall is formed in sections and the upper section is curved so as to extend partly over the top of the casing. A downwardly and rearwardly inclined wall 14 extends from the horizontal portion of the front wall to the side wall 11.
It is to be understood that any suitable form of easing may be used in connection wlth my improved pump operating mechanism, but that the one described is the preferred form.
In carrying out my invent-ion, I provide a tubular guide 15, which is provided upon opposite sides with laterally extending flanges 16, which are enlarged adjacent their outer edges, as indicated at 17. The edges of these flanges abut against the side walls of the casing, as clearly shown in Fig. 3, and are secured thereto by screws 18, which extend through the walls into threaded openings formed in the-flanges. A cylindrical rack bar 19 having a flattened side 20 with transversely extending teeth 21 formed thereon, is movable through the guide. The means which I have provided for reciprocating the rack bar include a pinion 22 which projects through an opening 23 formed in the guide and which is adapted to mesh with the teeth formed on the rack bar. The pinion is rigid with a shaft 24: which extends through a bearing 25 formed upon one side of the casing. A crank 26 is secured to the outer end of the shaft 2 1, which projects a sufficient distance beyond the side of the casing. A handle 27 is secured to the end of thecrank and provides means whereby the pinion may be easily rotated.
A fluid measuring pump which is described in detail and claimed in a concurrent application and which includes generally a working cylinder 28, an intake cylinder 29, and a discharge cylinder 30, is secured under the platform 9 by means of rods 31. These rods are rigidly secured to the top of the working cylinder 28, extend through the opening 7 and the base 9 of the casing, and are held against movement by the nuts 32 or other suitable means. The
A. register 41 is secured to the front wall of the casing and is visible through an opening 1-2 formed therein. This register is for the purpose of recording the amount of liquid which flows through the nozzle and is operated by means of the links 43 and 14:, which are connected to each other and to the register and pinion 22, respec tively. The link 4st is connected to the pinion by means of a crank pin 45.
In operation, the rack bar 19' is moved by a rotation of the crank 26, first in one di rection and then in the reverse direction. A complete rotation of the crank causes aknown amount of liquid to be discharged from the pump and flow from the spout 40' and the register 41 records the same.
From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have provided an extremely simple and efficient pump operating mechanism, which may be very cheaply manufactured and which is especially adapted for use in connection with fluid measuring pumps.
It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may fmake such changes as will fall within the spirit and scope of the mvention.
Having thus described my invention, what 1. In a pump operating mechanism a casmg, a tubular guide positioned wlthin said casing, longitudinal flanges formed upon opposite sides of the guide and engaging the interior of the casing, means for rigidly securing the flanges to the walls of the casing whereby the guide is supported and the casing braced, said guide being formed with an opening in the body thereof, a rack bar movable through the guide and means eX- tendiug through the opening into engagement with the bar to actuate the latter.
2. In combination with a fluid displacement member and a casing, of a rack bar secured to said fluid displacement member, a guide having flanges formed on the sides thereof adapted to engage the walls of the casing, means for securing the flanges thereto, a shaft extending into the casing, a pinion rigid with said shaft, the guide being apertured to permit of the pinion meshing with the rack bar, and a crank rigid with the shaft.
In testimony whereof I a'tlix my signature in presence of two witnesses.
