ELECTRIC AIR-PUMP.
SPECIFICATION forming part of Letters Patent No. 337,804, dated March 9, 1886.
Application filed December 9, 1885. Serial No. 185,119. (No model.)
' and exact description,setting forth in general and in detail my invention.
My invention relates to improvements upon a former application filed by me in the United States Patent Office. In that application were shown devices adapted to accomplish the same object as the present invention. The device now sought to be covered by a patent acts upon the same general principles, but is much simpler of construction,in that the number of elements necessary to accomplish the same result is greatly diminished.
The object of my invention is to provide,in combination with the piston, a switch which will alternately and automatically include magnets in an electric circuit, and in combination with the valves ratchet and pinion gearing adapted to be operated by the armatures of said magnets.
In order to illustrate the practical manner of carrying out the invention and to enable others to construct and use the same, drawings are hereunto annexed and described, in which similar characters of reference represent corresponding elements.
Those devices or portions of any device mentioned in the description, but not shown in the drawing, are either exact duplicates of elements which are shown in another part of the drawing, or else the elements alluded to, but not shown, are well known in the art or are not a part of the invention.
The drawing aims to point out the invention only. Those parts delineated but not referred to are not a part of the invention. The materials of construction, the proportional dimensions, and the exact forms of design are not in every instance alluded to.
The portion of the device embodying my invention, as shown in the single figure, consists of the combination of the usual cylinder, A, piston B, (shown dotted,) operating-handle O, and valve D, and electro-magnet, E, an armature, F, to said magnet, gearing connecting said armature to said valve, consisting of two ratchets, G and G, the one fixed to the armature and the other to the valve, and a pinion, H, gearing into both ratchets, and an automatic switch in circuit with said magnet, consisting of a contact-piece, I, mounted upon a rod,X, movable in bearings K and L, cords M and N, secured to said contact-piece, passing over pulleys O and P, and connected to said operating-handle.
Some of the details of construction are as follows: A second magnet, E,is also provided. It is for the purpose of operating a valve and its gearing located in the chamber Q and concealed from sight, said valve and its gearing being of the same construction as those already described, aud serving as the ordinary exit-valve often found in vacuum air-pumps. There is one electric generator, R, and circuits through both magnets, the terminals being at the switch. There are three terminals, a, b, and c, as shown. If a and c are connected the magnet E is in circuit, while if a and b are connected the magnet E is in circuit.
In practice the pipe S, connecting the cylinder A with the chamber Q, would be much shorter, for reasons well known to-those versed in the art. It should be as short as the other constructions will allow. Part of the pistonrod T of the supporting-pillar and of the cords M and N are broken away in order to bring the drawing within as small limits as possible. The receiver V illustrates an inclosed space desired to be exhausted of air. The contactpiece I is mounted in an insulating substance, WV, which is fixed to the rod X, mounted in bearings and adapted to move longitudinally, so as to come into contact with the metallic pieces Y and Z, insulated from each other by the pieces (I and e.
A bent lever serves as a support for one end ofthe cord. This cord should be long enough, so that in an extreme position of the pistonas, for instance, as shown in the drawing, at the top of the cylinderit will be loose upon one side between the pulley O and handle 0. In short, the cord should be long enough to be loose instead of tight, and of such a looseness that the contact-pieces I will be set upon the piece Z when the piston is at the top, and on the piece Y when the piston is at the bottom, of the cylinder.
The modus operandi is similar to that of other pumps, except as regards the electrical features. The upward and downward movements of the pump-handle switch the current through one or the other of the magnets,which vattract their armatures to open the valves.
' palnying drawing, having particularly ascertained the manner in which thesameoperates to accomplish the said object, having for the mere sake of formality illustrated a modification of said invention, and having intimated that it is applicable to other purposes than those mentioned, what I consider to be novel and original, and therefore claim as my invention, is
1. In an air-pump, the combination o'f'the usual cylinderpistonand valve,a switch geared to said piston and an electro-magnet armature geared to said valve, the gearing of said armatureconsisting of two ratchets, the one upon a rod fixed to the armature and the other upon a rod fixed to the valve, and a pinion gearing into both ratchets, substantially as described.
2. In an air-pump, the combination of the usual cylinder-piston, operating handle and valve, an electro-magnet, an armature to said magnet, gearing connecting said armature to said valve, and an automatic switch in circuit with said magnet, said switch consisting of a contact-piece mounted upon a rod movable in bearings, cords secured to said contact-piece passing over pulleys and connected to said operating-handle, substantially as and for the purpose described.
In testimony whereof I hereunto subscribe my name, in the presence of two'subscribing witnesses, this 1st day of December, A. D. 1885.
