' PUMP.
SPECIFICATION forming part of Letters Patent No. 612,834, dated ctober 25, 1898.
I Applloeton llled December 15, 1897. Serial No. 661,975. (No model.)
To a/ZZ whom/'it may concern:
Be it known that I, DIEDRICH DIECKMANN, a citizen ofthe United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pumps, of which the following is a specification.
This invention relates toapumpof the class in which a curved flexible tube is compressed by a rotating roller, which causes a' suction at its rear and a forcing eect at its front.
The invention consists more particularly in various features of construction by which the different sections of the pump are greatlyimproved and the general efficiency of the pump is increased.
In the accompanying drawings, Figure 1 is a vertical central section of my improved pump on line 1 1, Fig. 2. Fig. 2 is a plan partly broken away; Fig. 3, a cross-section 0n line 3 3,`Fig. 1; and Fig. 4,-a cross-section through the flexible tube c.
The letter a represents the base-platelet the pump, bolted to a suitable support b and provided with a pair of concentric flanges a', between which the flexible tube c, having inlet and exit connections c' c2, is seated. Y The bore of this tube is not circular, but oblong laterally and contracted at the tcp, it being substantially of isoseeles-triangular form in cross-section, with a curved base, Fig. 4, which insures the complete closing of the tube, particularly at its lateral folds, under pressure, Fig. 1.l The tube is attached to the base-plate a by means of headed screwbolts o8, the heads of which are molded into the tube, while the exposed lower ends are adapted to receive the fastening-nuts c4. End nipples c, also molded into the tube, serve for theattachmcnt of the inlet and exit pipes c' c2, between which pipes the tube contains a solid abutment, (indicated by the dotted lines c c, Fig. 2.) i
From the center of the base-plate a projects upwardly a stud or shaft d, around which is free to revolve a top plate or spider e, surrounded Vbya ily-wheel f, which is bolted to the periphery of plate e at e' and carries the handle f', by means of which the wheel o f and plate e are jointly revolved.` The plate .tive position.
e carries a depending cireular'flange e2, which overlaps the outer flange a' of base-plate a to inelose and protect the tube c.
Directly above the tube c the plate e is provided with two (more or less) slots to accommodate the tapering rollers g, which `are adapted to compress the tube c during their rotation, and which, together with such tube, constitute the operative mechanism of the pump. Each of the rollers g revolves on a shaft g', supported in the depending arms of a U-shaped bearing g2, hinged to plate e at gs. A clamp screw g4 normally locks the outer end of the bearing to the plate e, so that such bearing is maintained in its opera- Sheuld it be desired to obtain access to the roller, the screw g4 is slackened and the bearing q2 thrown upon its hinge, when the roller will be fully exposed.
To regulate the pressure of the rollers upon the tube, I fit upon the upper threaded end of stud d a nut d', which engages the hub of plate e, and thus serves to adjust the hori zontal plane of rotation of the rollers.
It will be seen that my improved pump is effective in operation, that its parte are readilyassemb1ed,and that it may be easily taken apart for the purpose of inspection or repair.
What I claim is- 1. In a pump the combination of a flexible tube, with an upper plate, a bearing hinged to the plate, means for locking the bearing to the plate, and a roller hung inthe bearing and adapted to engage the tube, substantially as specified.
2. In a pump the combination of a flexible tube with an upper plate, a bearing secured thereto, a roller hung in the bearing and" adapted to engage the tube, a fly-wheel surrounding the plate, and a handle carried by the wheel, substantially as specified.
3. In a pump, the combination of a flexible tube the bore of which is of isosceles-triangular form with a curved base in cross-section, with a rotary roller adapted to engage and compress said tube, substantially as specified.
4. In a pump the combination of a flanged base with a ,flexible tube seated thereon, means for connecting the tube to the base, a
TOO
shaft, an upper revoluble plate, a bearing York and State of New York, this 3d day of hinged to the plate, means for locking the December, A. D. 1897.
bem-innto the plate, a rollel carried by the y bearinf and adapted to vengage the tube, and DIEDR-ICH DIEOKMANN 5 a y-wheol surrounding .the plate, substan- Witnesses:
tially as specified. F. v. BRIESEN,
Signed at New York, in the 'county of New HERMAN MUNDGENY.
