TIMER. I APPLICATION FILED NOV-6,1916- Patgnted Dec. 11,1917.
a citizen of the United States CLIFTON R. HOLMES, OF MOIhT'I'GOMERY, MICHIGAN.
' TIMER.
Specification of Letters Patent.
Patented Dec. 11, 1917.
Application filed November 6, 1918. Serial No. 129,844.
Toiall whom it may concern:
-Be it known that I, CLIFTON R.' HOLMES, residing at Montgomery, in the county of ilillsdale and State of Michigan, have invented certain new and useful Improvements in Timers; and I do 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 same. I
My invention has for its object to improve upon the construction shownin my allowed U. S. patent application Serial No. 78,939, filed February 17, 1916, the principal end in view being more simple and less expensive construction without sacrificing any advantages. v
\Vith thejforegoing general object in view the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a part of this application and in which:
Figure 1 is a vertical longitudinal section of the improved timer;
Figs. 2 and 3 are vertical transverse sections on the planes of the lines 22 and 3-3 of Fig. 1; and,
Fig. 4 is a perspective view of one of the ring supporting brackets.
In the drawings above briefly described the numeral 1 designates a cylindrical casing having a closed end 2 which is preferably though not necessarily of conical formation, said casing being adapted to be supported in such a manner as to permit it-to turn upon its axis in the usual manner, an arm 3 being provided for the attachment of suitable operating means.
Positioned coaxially in the casing 1 is a flat ring 5 of compressed fiber or other appropriate insulating material, said ring having formed therethrough a plurality of openings 5 whose axes are parallel to the axis of the casing, said openings equaling in number the number of cylinders of the engine with which the timer is to be used.
A plurality of ring supporting brackets 6 are provided, said brackets being equal in number to the openings 5 for a purpose to appear. Each bracket 6 is preferably formed of a single plate stamped from'sheetmetal and bent into L-shape, said brackets having one of their arms 7 extending over one end of the openings 5 and secured in contact with one fiat face of the ring 4 by screws 8 passing through said arms as shown. The other arms 9 of the brackets 6 are parallel with the axis of the casing 1 and extend across the peripheral edge of the ring 4 in spaced relation thereto, being insulated from the curved Wallof said casing by washers 10 or the like.
Binding posts 11 are insulated from the aforesaid curved wall of the casing 1- and pass therethrough and through the arms 9, whereby to efi'ectively secure the brackets 6 in operative position and at the same time to provide means for connecting the current distributing wires with said brackets.
Contact plugs 12 are seated immovably in the openings 5 with their outer ends flush with the flat face of the ring 4 opposite that to which the arms 7 are secured, electrical connectors 13 in the form of coiled springs being housed within said openings 5'between the. plugs and arms in question and in contact with both.
The hub14 of a disk 15 is keyed on the timer shaft 16 which projects into the easing 1, said disk 15 carrying a socket 17 which opens toward the ring 4, said socket receiving slidably therein a brush 18 to whose inner end a coiled spring '19 is 59 curedin any preferred manner at one of its ends, the other end of said spring being secured to the disk. The brush 18 is adapted to successively contact with the lugs 12'to complete the circuit of the spar plugs of the engine and. travels between said plugs parts become glazed by continual sliding one upon the other, and thus reduce friction and wear to a minimum without the use of grease in the casing 1. I claim:
1. A timer comprising a cylindrical casing, a fiat ring of insulating material positionedcoaxially in said casing and out of contact therewith, said ring having a plurality of openin s therethrough with their axes parallel witi the axis of the casing L- shaped ring-supporting brackets having one arm disposed over one end of the aforesaid openings and secured tonne face of the ring, the other a'rms of said brackets being insulated from the curved walisofvthe casing, binding posts insulated from said Wall and passing therethrough and through the last named arms of the brackets to secure said brackets in position and-at the same time to afford means for connecting distributing Wires thereto, contact plugs in the aforesaid openings and flush With the face of the ring opposite that to which the first named arms of the brackets are secured and a rotary brush operating over said last named face of the ring for successive contact With said plugs.
2. A timer comprising a cylindrical or sing, a flat ring of insulating material positioned coaxially insaid casing and out of contact therewith, said ring having formed thcrethrough a plurality of openings Whose axes are parallel With the axis of the easing, an equal plurality of ring-supporting brackets formedof sheet metal plates bent into L-shape, said brackets having one of their arms disposed in'contact with one fiat face of the ring and extending over one end of the aforesaid openings, screws passing through these ends of the brackets and into the ring to secure the latter rigidly thereto, the other arms of the brackets being parallel with the axis of the casing, extending across the outer edge of the ring andbeing insulated from the curved Wall of said casing, binding posts also insulated from said Wall and passing therethrough and through the last named arms of the brackets, contact plugs fitting immovably in the aforesaid openings With one end flush with the fiat In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
