Application filed December 10,
To aZZwhomz't-ma ,concem:
Be it known t at 1, CHARLES H. Bonn- MEYER, a citizen ofthe United States, residing at Baltimore city, Statefof Maryland, have invented. certain new and useful Improvements in Timers for Internal-Combustion Engines, specification.
Specification of Letters Patent.
of whichthe following is a This invention relates to devices for timing the explosionsin internal-combustion and more particularly to a device of thiskind used in ,connectionwith the well- -known Ford motor. i
,The invention has for its object to provide a timer or commutator which is and reliable/in. operation, and which is so very efficient I constructed that repair-sand replacements v are readily made.
The invention. also has for its object to provide the-device with a'very simple means for connecting the current wires, the connection being alsosoarranged that the wires cannot become fouled from oil.
Other objects and advantages 'of the invention; will be .poin description appearing hereinafter, and in order that the samemaybe better'under-. stood, reference is had to the accompanying drawingformmga partof this specification. I
In the drawing- Figure 1 is a cross-section of the device; Fig. Qisa front elevation thereof; Fig. 3 is a plan view of the commutator shell; ig. 4
'19 asfshown in Fig- 1 ed out in the detailed is a rear elevation ofsaid shell; Fig. 5 is an edge view of a contactsupporting member; Fig. 6 is a rear elevation of said memher, and Fig.' 7 is a sectional detail on the 6. Referring specifical'l denotes thensual shell the SamebeingprQYided,with a radial arm 11 forconnection of the pull rod of thespark lever mechanism. The shell 10lis rotatably' Supported, asusual on a,hearin f;12 on the engine cover 12ft, The lcapn sha t 13'passes into the shell-.10 .and-Jon the i'i'iside of latter it is fitted with cuit.
The commutator 03, 3. 1? I Q' I re Shown at 14, theybeing embedded inadisk 15 of matenal'flush referably,

made of phosphor bronze and the disk is made of condensite, these two materials having substantially the same wearing qualities. An even wear is therefore had and the brush will not wear the surface over which it travels rough, If any uneven wear or roughness should occuiythe disk 15 can be re moved from the shell 10 and smoothed down by agrinding or'other process. The man'- ner in 'which't'he disk 15 is mounted in the shell 10 for ready removal will be presently described. I
. From each contact point 14 leads a wire 16, the'same being embedded in the disk 15, and on the rear face of the latter is an enlargement or protuberance 17 to which the respective'wires lead. In the part 17 are embedded metallic socket pieces 18 to which the wires 16 are connected, and adapted to enter these socket pieces are plugs 19 carried by a block20 of insulating material. The primary wires21 are connected to the plugs and said wires are housed in a flexible, metallic sheath 22. The side ofthefshell 10 has an opening for insertion of the block 20 to engage the plugs 19 with the sockets 18, and from this opening extends a threaded nipple 24 on which is screwed ac-105m sleeve 25.
' It will be seen from the foregoing that the .wirin of the" commutator is completely house in so 'thatit cannot get oil soaked or fouled, and it is also protected against the nipple 24 has'a longitudinal rib 26 and thesi de of the block 20 has a groove 27 to seat said rib and thus center the block. The block 20 cantherefore' be inserted in one way only, and that the right Way to prop- 'erly enter thcplugs 19 into the sockets 18. I The disk 15 is removably'mounted in the shell 1i), and it is fastened therein by screws27 passing through the front wall "of the shell'a'nd threaded into the disk. On the sidewall ofthe shell 10 are lugs 28, and the 1 disk 15 hasperipheral notches 29 to slip over said'lugs, whereby the disk is properly' giliided and centered when it is inserted into't esheu. f
which is fittedjat its outer end with a'cap 31 A
