CIRCUIT-CLOSER FOR EXPLOSIVE-ENGIN ES.
Patented Dec. 17, 1907.
To all whom it may concern:
Be it known that I, THOMAS ALTON BE- MUS, of Boston, in the county of Suffolk and State of Massachusetts, have invented'certain new and useful Improvements in Circuit- Closers for Explosive-En ines; 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 The primary object of this invention is to provide a high tension distributer or circuit closer which will be so simple in construction as to permit of the ready assemblage and remova of its parts, even by those not skilled in the art, and furthermore one which will be I composed of but so few parts that dan ef of derangement is greatly reduced. An further objects are to have the gaps for'the sparks in the secondary. circuit as short as possible; to enable the parts to be readily iiispected without having to remove any portion of the inclosure; and to provide a distributor which will be inexpensive, durable, self adjustable, and ositive in o eration.
The invention will be hereina ter fully set forth and particularly pointed out in the clailns. I In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is an end view. Fig.
3 shows in perspective the primary (1 secondary brushes. Fig. 4 is a sectioiijel view throughthe primary brush. Fig. 5 is a longitudinal sectional view. Referrin to the drawings, 1 designates the rotary sha t upon which the circuit closer is located, such shaft being preferably that by which the valves of'an explosive engine are operated, or it may be separate and geared to such shaft.
2 designates an inclosing casing preferably constructed throughout of insulating material, with the exception of the inner end" cover plate 3 which is preferably made of metal. The casing 2 is shown as being made up of ,three separate parts united by screws 4, although it is manifest that it may be made in one piece. At itsinner end it is equipped with threaded rods 5 which project t rough openings in cover plate 3, the parts being locked together by thumb nuts 6. The cover late at its axis carries a bush ing 7 wherein fits a sleeve 8 Which'is held by portion of casing 2.
- Application filed Odto'ber 2,1966? Serial No. 281.054.
- screw 9 to shaft 1, the flange of suchlatter sleeve being held up against that-of the bushing. That portion of sleeve 8, projecting beyond the plane of the inner face of plate 3 is reduced andsplit, and into this split portion fits the reduced end of a plug 10 of insulating material. This plug is held by a s lit ring 12 encircling the reduced portion of sleeve 8, said ring servin also to lock the end plate on said sleeve, all eing so retained by a single screw 13 passed through the flanged ends of the split rmg.
14 designates the brush of the primary or low tension circuit, and is shown in the form of as ring-pressed ball mounted in an openende sleeve 15 .projectin at right angles from ring 12. This brush is'designed to engage with contacts shown in the form of plates 16 flush with the inner surface of the circumferential wall of the inner reduced I have shown four such contacts, all of which are electrically connectedvon' the outside of the casing by a metallic band '17, equipped with a binding post 18 to which the wire a: of the primary or low tension circuit is connected, such wire leading from a vibrator (not shown). One pole of a battery (not shown) is also connected to such vibrator, the other pole wire being grounded on the machine.
\ 19 designates the secondary or high tension brush which is shown in the form of an arm projecting radially from the end of plu 10, its inner cap-like end being fitted on sai plug. The outer end of this brush is designed to travel in close roximity to, but not to contact with, secon ary terminals 20, four of which are shown as being set in the circumferential wall of the outer, larger portion of the casing. From the binding posts 21 of these terminals lead the high tension wires y to the several spark plugs of the cylinders of an explosive engine.
The outer end of the casing is covered with a transparent disk 22, of insulating material, preferably glass, held in place by a ring 23, and at the center of this disk and passing therethrough is a binding post 24; to which the other wire 2 of the secondary or high .tension circuit is secured, such Wire leadin id'rom a single coil of the vibrator. This'bm ing post at its inner end has a contact-plate at the axial center of the disk in line with the end of plug 10 so as to be en-- 1s done t I gaged by a spring-pressed ball contact 25 in the end of such shaft, the ball projecting through an opening in the 'metalhc cap-like end of the secondary brush 19. By this means I am enabledto carry the hi h tension current through the end of the inc osing cas lng without creating a spark, the ball 25 remaining alwaysin engagement with the contact plate of post 24, thus avoidin using up additional energy which necessari where spark gaps occur. On the other handg the brush 19 is intended to travel in close proximity to the terminals 20, without engaging therewith, so that the spark gap will be as short as possible. With high tension currents, of course the jump may be almost any distance, but the smaller the gap the less energy required. The ball 25 is always changing its position and hence the contact is not liable to be impaired by the presence of grease, dirt, or other. foreign particles. This is also true of the ball contact 14 the engagement of which latter with the contacts 16 is insured by the centrifugal action independently of the'tension of its spring. The advantages of my invention are apparent. All of the brushes can be observed through the glass disk, which serves as an insulation for the high tension binding post. In this way it may be readily ascertained whether or not anything is visibly wrong. Access may be had through the outer end of the casing by removing the ring and glass, or the casing itself may with case here moved by takin off the thumb nuts 6. When this iiere is no danger of inexperienced persons getting the wires out of their proper positions, since they always remain secured to the casing. To the end plate 3 is secured a rod or wire 26 for shifting the position of the casing so as to advance or retard the closing of the circuits.
By means of my invention I am enabled to distribute high tension current from one coil to the sparkers of any number of cylinders. The low current circuit is closed through the machine at the same time the high tension current is being conducted from the vibrator coil to the distributer and through the sparkers to the engine and back to the battery through the grounding connection of the low tension current.
I claim as my invention 1. The herein described circuit closer comprising1 a sleeve, a plug of insulating material carrie by said sleeve, a casing mounted on and movable relative to said sleeve, a primary brush, a carrier therefor also mounted on said sleeve, a secondary brush carried by said plug, a secondary contact in engagement with said secondary brush, primar contacts mounted in said casing and wit which said primary brush is designed to engage, secondary terminals also mounted in said casing in proximity to the plane of y followsmovement of said secondary brush, and a secondary binding post in engagement with said secondary contact.
