UNITED STATES HOBART FREIBURGHOUSE, OF GOFF, KANSAS.

TIMER.

Application filed-November 2, 1922. Serial No. 598,463.

Tof all whom t .may concern.'

Be it knownthatI, HoBART FREIBURG- ing at, Goff, .in the county of Nemaha land v'State of Kansas have invented certain new and useful glmprovements 1n Timers, of

which the following isa specific-ation.

form otitimer `adapted for specific application to Ford automobilesfor overcoming the necessity of providing the usual spark coil for each cylinder, it being well known in this type of motor vehicle a spark coil is employed for each cylinder for building up the current between the magneto or battery and the contact points of the timer, insuring what is usually termed a hot spark.

A still further object of the present invention is the provision of such a timer that is simple in operation and comparatively inexpensive of manufacture and a timer that when once installed is not liable to readily become out of order` With the above and other objects in view as the nature of the invention will be better understood by reference to the accompanying drawings forming part of the present application, the same consisist of the combination and arrangement of parts hereinafter more fully described In the accompanying drawings, wherein like reference characters indicate corresponding parts throughout the several views:-

Figure 1 is a front elevational view of the timer casing clearly disclosing the spaced contact points arranged therein, and also setting forth an additional contact point, centrally disposed within the timer, and constructed in accorda-nce with the present invention.

Figure 2 is a cross sectional view upon the line 2-2 of Figure 1.

Figure 3 is a View similar to Figure 2, but disclosing in addition to this figure, the rotating contact arm positioned upon the usual rotary shaft.

Figure 4 is a fragmentary side elevational view of the rotating contact member, a. portion of the same being shown in cross section, disclosing its connection to the rotary shaft, and

Figure 5 is a diagrammatic view of the electrical Wiring system, employed by me in the vehicle frame.

vthe application of thepresent device to an l u Iinternal combustionj engine. lH oUsu, a citizen ot the United` States, resid- -Referring to the several view, andparticularly to Figures/1 to 3 inclusive,` there is disclosed atimer embodyingthe usual fiber casing 1'having a lining 2 arranged ltherein. 'This casing 1 has the usual inter- The primalyobject of the present invenl tion` resides inthe provison of an improved nal equi-distantly spaced contact point-s 3, each ot the samesecured within the casing by the post members 4, passing through suitableopenings in the lining 2, and casing to Vbe theresecured by the binding nuts 5.

Centrally disposed within the` casing 1,

and'spaced inwardly of the rear wall thereof, is an annular shaped metallic disk 6, this disk is rigidly positioned within the casing by a screw threaded bolt member 7 formed upon the disk and extending outwardly of the casing as shown in Figures 2 and 3.

Extending within the casing as in the latter mentioned figure, is the outer end of the cam shaft 8, reduced and screw threaded at its extreme end portion 9 for screw threaded engagement within a screw threaded bore 10, of a fiber block 11. Suitably secured to this fiber block is the usual metallic arm 12, carrying a roller contact 135 for engagement with spaced stationary contacts 3, within the casing 1 when the cam shaft 8 is rotated.

Centrally supported upon the rear wall of the liber block 11, is a horizontally extending relative sensitive helical spring 14, adapted to have its free projecting end 14 contacting with the annular disk 6 of the casing 1 as clearly shown in Figure 3. Conveniently supported upon the upper longitudinal surface of the liber block 11 is a flat-like metallic arm 15 having its outer end 15 curved downwardly for contact with one of the convolutes of the above mentioned coil spring 14. This metallic arm 15 may be secured to the fiber block by a set screw or the like having a knurled annular head 16.

In the diagrammatic view, Figure 5, the stationary contact points 3 are shown as being electrically connected to the several spark plugs 17 of an internal combustion engine by electric wires A, the said spark plugs being suitably grounded as at 18 to The flat-like contact disk 6 in the casing 1 is connected through the instrumentality of the binding post 7, with one end of a high tension wire Z) from the single spark coil o, this coil also ""2 14e and metallic arm 15,.it will be readily understood that the current from thehigh tension wire is carried by the spring le to the roller i3 which makes lContact with the stationary points 3, each of which is "f connectedto its appropriate plug 17. for

iii-ing these plugs in each cylinder at the predetermined time as is now the case With the conventional form of timer.

While the form ot the invention hereinshown and-described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms', modifications and arrangements of the parts may be made Without departing from the spirit and scope of the invention as claimed.

VVhatI claim as new is A timer comprising a shell, a lining of insulating material located therein, a plurality. "of spaced contacts passing transversely through the shell and lining, a block mounted for rotation in the shell, a brush carried by the block for successive engagement With the contacts, a. bar arranged Within the lining, a binding post connected with the bar and passing through the lining and shell, a coil spring interposed between the bar andthe bloekland connected with the bar, and a. conductor mounted upon the block and having an angularly disposed. end portion Which engages the convolution of the coil springs.
