Application filed December 14, 1917. -Seria1Ro.207,027.

To all whom it may concern Be it known that we, CHARLES LAPORTE and IVAN Onnnsno, both citizens of the United States of America, residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Combined Oil- Pumps and Ignition-DistributerMountings, of which the following is a specification, reference being had therein to the accompanying drawings.

he invention relates to engines and has particular reference to the construction of the ignition distributer and oil pump. It is the object of the invention to provide a c0n1- bined unit which may be readily mounted on or detached from the engine housing, and to this end comprises the construction as here inafter set forth.

In the drawings:

Figure 1 is a sectional end elevation.

Fig. 2 is an elevation at right angles to Fig. 1.

.A is the engine casing having an extension at one end thereof forming the ledge B, and Cis a driven shaft within the housing having mounted on its end portion a gear D preferably of a spiral type. Our improved unit is mounted upon the ledge B and is driven from the gear D. Specifically the construction comprises a casing .E for the pump, which as shown is of the gear type. The driving shaft F for. the pump extends vertically and is provided at its lower end with a spiral gear G for engaging with the gear D, the former being insertible through an aperture H in the ledge B. Adjacent to the gear G is a bearing I, which is formed on a lower section J of the casing E, the hearmg I being also insertible through the aperture H and having a-;porti0n I for fitting said aperture and positioning the gear. K and K are the inter-meshing gears of the ump arranged in a recess in the casing E. he shaft F passes through the casing E and extends upward thereabove, the upward extension being housed in atube L which is secured to a boss M on the homing E by means of a set serew N.' At the upper end' of the tube L is a casing O for the distribu ter (not shown) which is driven fromthe extension of the shaft F.

With. the. construction as described, the

housing E,may be secured in position by suitable means, such as thebolts and when ing, a driven shaft insaid casin insertible through I Y thus secured will hold the shaft F and spiral gear in proper positions for the meshing of the latter with the driving gear D. In

operation, the oil which is propelled by the pump is delivered through suitable channels in the casing, such as Q, and any leakage around the shaft through the bearingsinto the tube L is permitted to drain back into the crank case through the channel R.

. What we claim as our invention is:

1. The combination with an engine casand a gear-wheel thereoli, of a combine .pump and ignition timer unit-mounted outside of said casing and provided with a drive-shaft and gearmounted thereon and projecting through an aperture in said easing into ongagement with the gear therein.

. 2. In an engine,the combination with the casing having a projecting portion forming 3. 111 an engine, the combination with a casing having a projecting portion forming a horizontal ledge and a drivenshaft within said portion having a gear-wheel gnounted thereon, of a combined pump and ignition timer unit mounted'on said led said unit. comprising a pump casing, a s aft extending vertically therethrough and projecting upward and downward therefrom, a tubs lar housing for the portion of said shaft above said casing having an enlargement at its upper'end for an ignition timer driven by said shaft, a downwardly-pro'ecting portion on said casing for-min a caring for the downward extension or the shaft and having a port-ion fittin an aperture in the ledge of said casing, an a gear-wheel at the lower end of said shaft insertible through said .aoerture in the casin and positioned to mes with the first-mentioned gear-wheel within said casing.

4. In an engine, the combination with a casing having a njecting portion forming a horizontal edge an a driven shaft in said casing with a gear-wheel mounted thereon, of a combined pump and ignition timer unit mounted on the ledge of said casing comprising a housing for the pump, a tubular housing connected thereto and extending upward therefrom, a housing for the timer at the upper end of said tubular housing, a shaft, extending vertically through said housings forming a driver for the pump and timer the lower end of said shaft projecting downward and having a gear-wheel mounted thereon, said gear-wheel and downwardly-projeeting portion of the shaft being insertible through an aperture in the ledge of said casing and into operative relation with the first-mentioned gea Wheel Within the casing, and means for detachably securing said unit to said ledge.

5. In an engine the combination with the casing having a hollow projection portion and a driven shaft and gear thereon Within said portion, of a combined pump'and ignition timer unit seated uponand secured to the projecting portion of the casin said unit having a part extending into said projecting portion of the casing with a shaft mounted in said part and a gear mounted thereon. the last-mentioned gear and said part of the unit being insertible through an aperture in the projecting portion of the easing into engagement with the ear Within said portion.

(3. In an engine, the combination with a casing having a projecting portion forming a ledge, of a combined pump and ignition timer unit seated upon and secured. to the ledge of said c; :ing, said unit having a downwardly-projecting portion with a shaft.

extending therethrough carrying a driving member, said driving member and down Wardly-extendmg portion being insertibie of the easthrough an apertme in the ledge ing and means Within the of the casing for actie.v i member.

In testimony whereof WC tures.
