EiDWIN GUTI- I RIE, OF WASHINGTON, DISTRICT OF COLUMBIA.

ENGINE-STARTER.

To a 10110712; it in try concern Be 1t known that I. EDWIN GUTHRIE, a citizen of. the United States, residingnt Vashington, in the District of Columbia, have invented certain new and useful Improvements 1n Engine-Starters, of which the' following is a specification.

This 1nvention relates to englne starters, and belongs to that class of'devices intended to rotate the shaft of a gas engine to set the engine in motion, without employing the the tank by the repeated explosions in the usual hand crank.

The object of thisinvention is to provide, in connection with a. tank for the storageof gas under pressure, a'ventilating fan having parts of special arrangement and construction and carrying peripheral buckets.

upon which the stored gas, directed by ad jacent jet nozzl'es, may be impelled to revolve the fan, and, the engine shaftgwith which the fan is operatively connected.

The'accompanying drawings illustrate the :preferred method-of carrying out this invention.

Figure 1 shows the rear side of a radiator with this inventionapplied, and sets forth the connection between the fan and the shaft oftheen'gine. Fig. 2 represents the vertical section of a cylinder of a. gas engine, and shows the connection between the cylinder and storage tank for collecting the gas under pressure, and in this figure likewise appear the plurality of check-valves employed in the connecting tube. Fig. 3 is a top plan view of the engine, and aportion of the frame of a motor vehicle, and shows this invention in pro-per posit-ion with respect to the various parts concerned. Fig. at is a top view, looking into the curved side of the jets segment.

Throughout the drawings" and description, the same letter refers to the same'part.

The frame A of the-vehicle carriestheengine I having engine shaft I), which may be rotated by the customary hand crank C.

In rear of the radiator I) is the fan E supported by a bearing bracket attached to the engine bed. The fan, which is inten tiQnally' constructed stout enough for the service expected of it, is provided with a peripheral ring F having spaced buckets f, best shownin Fig. 1. The scale of drawing in that figure is slightly enlarged, and, the size of the buckets somewhat exaggerated. with reference to the size of the fan, for the purpose of rendering the illustration plainer.

Specification of Letters Patent. Application filed March 1, 1912.

Patented May 28,1912. Serial No. 680,913.

A sprocket wheel Gr secured to the fan shaft, connected by chain 9 with the sprocket H secured on the engine shaft 6.

The engine may have one or more cylinders J and j, connected by the tube K with'a storage tank is, and including more than one check valve L and M. One checkvalve is usually located near the engine, and

the other near the tank. The object in havg5 ing more than one check-valve is to lessen the vibration of the'body of gas stored in K is shown to be connected in Fig. 2. t;

Considering Figs. 1, 2, and 3, the tube m is shown. It leads from the tank to the plug valve N, which has an operating lever n pivotally coupled by connecting rod 0 with the bell crank P. The other leg of the bell c 'ank is connected with the draw rod Q leading to any convenient point, and by which the plug valve may be turned. The turning of the valve N admits stored gas into the hollow jets segment R, that is constructed so with a number of jet nozzles r directed toward the buckets f on the periphery of the fan. The gasstored being very 'hot, it is advantageous that the storage tank shall be supported at some point below the frame 5 where air may freely flow, over it when the vehicle is in motion. If the engine will not start on spark, the rod Q, is actuated and the contents of tank l:,in whole or in part,

are discharged against the buckets There 0 are a number of jet nozzles, in order thatthe impact and reaction of the gas may afiect a number of the buckets at the same time, and, taking into consideration the leverage available by reason of the diameter of the fan, considerable turning power is exerted. QHavin'g now described this invention, and explained the mode of its operation, what I claim is 4 1. In an engine starter, the 'con'ibin'ation loowith an englne having an englne shaft, of

a revoluble. fan arranged to cause. air to flow over the engine to cool the same, the said fan havin a series of buckets means constructed to transmit the movement 'of theengine shaft to thefan and the movement of the fan-to the engine shaft, a fluid storage tank, a member having jet nozzles directed toward the buckets of the'fan, and tubular connections including a cut-off valve and arranged between the tank and said member. 2. In an englne starter,'the combination having a series of buckets; means-constructed.

tr. bransnnt the movement of the engine shaft to the fan and the movement ofthe fanto the engine shaft, a fluidstorage tank, a member! having jet nozzles directed towardthe buckets of the fan, and tubular connections including a cut-off valve and-arranged between the tank and said member.

3. In an-engine starter; the combination with an engine having an}engine shaft, of a revol-uble fan arranged to cause air to flow I over the engine to cool the same, means constructed to transmit the movement of the. engineshaft to thev fan and the movement of the fan to the engine shaft; a fluid storage tank; a member having jet nozzles directed towardthe vfan, the said fan being constructed to be revolved by impinging'fluid jets from said member, and tubular connections including a cut-offvalve and extendin between the said storage tank and the sai member,

In testimon whereof I aifix my signature m presence 0 two wltnesses.

EDWIN GUTHRIE.
