PUNK? BASE Filed Sept. 8, 1958 INVENTOR. 4/11/05 6'. 1905554! PUMP BASE Linus E. Russe, Springfield, Ohio, assignor tu Peters &
This invention relates to base constructions for stirrup pumps and like devices, and especially to a formed stirrup-like member of especial utility in this connection.
The object of the invention is to simplify the construction as well as the means and mode of operation of pump bases, whereby such bases may not only be economically manufiactured, but Will be more efiicient and satisfactory in use, adaptable to wide variety of applications, and be unlikely to get out of order.
A further objectof the invention is to provide a formed sheet metal base for stirrup pumps and like devices, it being contemplated in this regard to obviate the relatively heavy devices of the prior art having a screw threaded or other fixed association With the pump cylinder.
Another object of the invention is to present a formed sheet metal base as described providing in and of itself an area of containment for the lower end of the cylinder, With adequate access to the interior thereof, as Well as abutment means to accept upward thrusts delivered by pulling motions upon the cylinder, such thrusts being absorbed by the foot of the operator applied to the stirrup base.
A further object of the invention is to provide a generally new stirrup-like base as described incorporating clamping devices and readily adapted for attachment to any detachment from the pump cylinder.
A further object of the invention is to provide a pump base possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein mentioned.
With the above and other incidental objects in view as Will more fully appear in the specifioation, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation as hereinafter described or illustrated in the accompanying drawings, or their equivalents.
Referring to the accompanying drawing wherein is shown one but obviously not necessarily the only form of embodiment of the invention:
Fig. 1 is a view in perspective of a base for stirrup pumps and the 1ike in accordance With the illustrated embodiment of the invention, shown mounted upon the lower end of a cylindrical band pump;
Fig. 2 is a view of the structure of Fig. 1 in side elevation; and
Fig. 3 is a top plan view of the base ai Figs. 1 and 2, pump parts being omitted.
Like parts are indicated by similar characters of reference throughout the several views.
Referring to the drawing, a pump of the kind to which a base in accordance With the present invention is applied comprises a cylinder on the lower end of which is an enlargernent 11 which may be either integral with the cylinder or a separate part attached thereto. A boss 12 on the enlargement 11 defineg an opening to the interim of the cylinder and serves as the inlet or the outlet tates ateit juncture of the cylinder 10 with the enlargement 11 there is defined an approximately radial projection or shoulder' 13 which is circular in shape in conformance with the cylindrical configuration of the cylinder 10 and enlargement 11.
The base structure is initially a strip of sheet metal which is bent about longitudinally spaced apart trans verse lines 14 and 15 to achieve an approximately U-shaped configuration made up of a planar tread or rest portionl6 and upstanding arms 17 and 18 extend upward to define a tubular clamp, abutment means and an area of containment as before mentioned, and it -Will be undrstood that the respective arms are identically formed and complement one another in the achieving of the desired conformations and configurations.
:For a short distance above the transverse lines 14 and 15 the arrus 17 and 18 incline at a graduati angle toward the vertical axis of: the rest portion 16. At a point 19 this angle of inclination becomes more acute and marginal portions of the arms progress in a line to a point. 21 where the respective arms are adjacent to the vertical axis of the rest portion 16, on opposite sides thereof, and so in adjacent relation to one another. From point 21, such marginal edges rise an appreciable extent in ior rgitudinal, parallel relatio-n to one another to define flanges '22. The respective' fianges o'n both marginal edges are perforated to receive clamping devices 23.
Intermediate their marginal edges, and starting from point 19 to the top of the flanges 22, the arms 17 and 18 are deformed outwardiy. In the area of the flanges 22, this deformation takes the shape of a semi-cylindrical recess 25 in each arm, the recesses being of longitudinal extent, paralieling the flanges 22, and further complementing one another to define in conjunction With the flanges 22 a tubular clamp to receive and to be adapted to the external configuration of the purnp cylinder 1G. Thus, as indicated in Fig. 1, the upper extremities of the arms 17 and 18 are formed with complementary semicyiindrioal recesses adapted to conform this part of the base structure to the configuration of the cylinder 10 so that upon tightening of the clamping devices or fasteners 23 the base Will be frictionally held to the cylinder. The clamp portion of the base is applied to the cylinder 10 immediately above the enlargement 11 which places the latter in position between the arms 17 and 18 and it will be understood that this Wiil be accomplished in a manner to permit the boss 12 to project outwardly between the arrns for the extension of a hose lime therefrorn. The intermediate portions of the arms 17 and 18, beneath the tubular clamp, are also deformed in the shape of a circular recess of longitudinal extent but in this instance the recess is of a progressive depth varying from la minimum depth at point 19 to a maximum depth at the base of the tubular clamp. This is accomplished by continuing the center line of each arm 17 and 18 in the angle of inclination which the arms have initially, and laterally curving the material of the arms to the marginal edges which ha in and define the more acute angle as described. T he result is, as indicated, to define an inner recessed area 26 in each arm 17 and 18, With the pair of arms cooperating to produce what may be considered an area of containment since it conforms itself approximately to curvature of the enlargement 11 and interfits With such curvature to obviate twisting or tilting movements of the cylinder 10 relatively to the base. Moreover, at its point of maximum depth, the circular recess 26 is connected to the base of the tubular clamp, or more particularly to the lower end of a semi-cylindrical portion 25, by an approximately radial shoulder 27 which overlies the shoulder 13 and forms an abutment means on the interim of the base to limit withdrawal of the cylinder relatively Patented Nov. 8, 19601 to, the base in an installed position of the partjs'.. 'I'he shoulders 27 have an arcuato shape and complement one another in achieving an abutment means conforming to the circular configuration of the shoulder 13.
When mounted to the cylnder 10, therefore, a base in accordance With the present invention becomes a secure part of the pu'mp facilitating and enabling its use as a stirrup pump. pump, merely by loosening or removing the devices 23, and, as is evident, is of a sirnple and inexpensive construction being made of a single piece of sheet metal and by a simple stamping or like manufacturing procedure.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable; but Which obvio-usly is susceptible of modification in its form, proportions, detail constmction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute the invention has -been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and constructon herein disclosed comprise but one of several modes of putting the inventon nto effect, and the invention is therefore claimed in any of its forms or modifications withn the legitimate and valid scope of the appended claim.
Having thus described my invention I claim:
