SPECIFICATION forming part of Letters Patent No. 299,532, dated June 3, 1884-.
Application filed May 22, 1883. (No model.)
To aZZ whmn it may concern:
Be it known that I, EUGENE L. FITCH, of Des Moines, in the county of Folk and State of Iowa, have invented a new and Improved Siphon-Starter, of which the following is a full, clear, and exact description.
The object of this invention is to provide a novel and convenient device for starting flexible siphons; and the invention consists of means whereby the siphon-tube maybe. conveniently grasped and compressed and the point of contact of the device with the tube shifted forward, thus expelling the air from the tube and drawing the siphon into action.
The invention also consists of the special construction, arrangement, and combination of the parts of the device, all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both figures.
Figure 1 shows my invention as I prefer to.
make it applied to a siphon-tube ready for use. Fig. 2 is a plan view of the same.
A B represent the grasping-plates of the device. These are duplicates of each other, and are struck from sheet metal, so as to form the side arms, a b, by which the plates are pivoted together, and also to form the shorter arms or projections a b, in which the rollers 0 (Z are journaled'. 1
O O are side springs, arranged to cause the rollers c d to grasp the tube D and collapse it, as shown in full lines-in Fig. l; but these springs might be omitted, if desired, leaving the plates A B free to be grasped by the hand of the user for collapsing the siphon-tube.
To the forward end of the plate A is attached the loop E, which surrounds the siphon-tube D, and serves as a guide to pre-' vent the rollers c d from running off from the tube D when the device is moved forward upon the tube for putting the siphon in action, and to the rear end of the plate Ais attached the ring F, which also surrounds the tube D. When the springs O O are not used, this ring F will be of considerable length, to act as a brace between the rear ends of the plates A B, for locking the rollers c d in position for collapsing the tube D, to cause the device to act asa faucet, when desired, for stopping the flow through the siphon; but when the springs are used this ring F will be made only of suitable size for dropping over the rear end of the plate B for holding the rollers c d apart, as shown .in dotted lines in Fig. 1, to permit the free flow of fluid'through the tube after starting the siphon.
For starting the siphon, the device will be placed upon the tube D and drawn backward on the tube near to the point where the tube enters the barrel G or other receptacle containing the liquid. The tube will now be compressed by the rollers c- (I; either by the springs C G acting upon the plate B, or by pressing the forward ends of the plates A B together by the hand, and then the device will be shoved or drawn forward upon the tube a distance somewhat greater than the length of the short arm of the siphon, which forward movement of the device will expel the air from the tube and cause it to fill with liquid, so that upon releasing the tube from between the rollers c d the liquid will flow. If the springs are used, the rear end of the plate B will now be pressed inwardly and the rear end of the plate B inserted in the lower end of the ring F, thus holding the rollers c d apart, and not pressing upon the tube D, so that the device may remain upon the tube, and not interfere with the flow of liquid; and when the device is so situated, if it is desired at any time to stop the flow, of liquid through the tube without breaking the action of the siphon, it is only necessary to slip the ring F oft from the plate B, whereupon the spring 0 O will cause the tube D to be collapsed by rollers c d and the flow out off. If no springs are used, the flow will be stopped by bracing the rear ends of the plates A B apart by the ring F, as above mentioned.
Instead of using the rollers c d, the plates A B might be made with fixed rounded grasping-surfaces for collapsing the siphon-tube.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The siphon-starter herein described, consisting of two spring-pressed plates hinged to each other, and carrying opposite rollers for grasping a tube, one of the spring-pressed plates being provided with aring at one end for engaging with the rear end of the other plate, substantially as shown and described.
, 2. The siphon-starter herein described, consisting of two spring-pressed plates hinged to each other, and carrying opposite rollers for grasping atube,one 0f thespring-pressedplates being provided with a ring at one end for engaging with the rear end of the other plate, and a guide-100p for the tube at its opposite end, substantially as shown and described.
3. I11 a siphon starter, the combination, with the hinged plates A B, formed with side with the hinged plate B, the plates A B being 20 adapted for grasping and collapsing the siphon-tnbe, substantially as described.
