Application filed December 30, 190'l.` v Serial No. $138,456.

To all whom it may concern;

Be it known that I, Henin' F. ii'innmnn.

acitiiten' .of the United tates, residing at Springtield, State ofOhio, have invented certain new Rotary Motors, of which the: following is tion, reference being had therein to the accompanying drawings. My invention relates to rotary motors and especially to a motor actuated by air or steam.

The object of my invention is to provide a motor which can be used for general purposes but is more particularly adapted te drive tube. cleaners, the niotorbeiug formed to follow the cleaner into the tube.

motor of this character must be conipact in forni and of such strength and durability as to withstand thesevere work incident to its use and it has been my object to provide a motor that will moet these requirements.

-A further-objecthas been to provide im# proved means to use the actuating incdiuni ansivel)lv thereby increasing the etliciency and economy of the motor; and l have further arranged to vary the ent oil as desired.

lVith tlies. and other objects in vien', in v invention consists of the construction and combination hereinafter described and .st-t forth in the elainis.

inthe accompanying drawings. Figure l is a longitudinal section of a motor embodying'niy invention. Fig. 2 is a cross section on the line Z Z of Fig. in feed head looking in the direction of the arrow. Figs. 3 and 4 taken on the line Y Y 0f Fig. l-Show a face vien' of Athe eut-ott val ve, the inlet ports of one side being shown open in Fig. 3 andthe opposite ports being shown open in Fig. 4t. Fig. 5. is'arross section through the ruimer and casing, taten on the line X X of Fig. 1. Fig. t is a view looking at the inner end of the feed head, showing the ports opening on to the valve and the sealing ring. Fig. 7 is a longitudinal sectional view of the motor taken on the Fig. 8 is a sectional view of the using showing an inlet and exhaust port ann a field of fine perforafions, with the casing partly broken awaylt show the conduits eading to said ports and field of perforations. Fig. 9 is a cross setlion on the line? P of Fig. 1, Fig. i0 is, sectional i showing inlet ports in the county ot Clark and f,

a specitieal vieu' through the feed head taken on the line A of Fig. '(3 showing the means of oiling the rear bearing of runner.

VIn the drawings a represents a casing, b a front and c-a rear head for saine. The front. head is shown screwed directly into the easing but the rear head is formed with a shoulder c1 and a screw threaded collar or coupling c2 abuttingv on said shoulder is screwed into the casing to hold the head in place.

A ruimer d is mounted on a shaft (Z1, the rear end of which is reduced and journaled in a recess, preferably having a bushing c, in the head c; and the forward or driving end of the shaft extends through and is journaled in an opening in the front head b, a bushing b1 being preferably used as a bearing for the shaft.

A chamber of such form and dimensions is provided that l,hen the runner is mounted therein it will contact the walls of the chamber inl two placesopposite each other forining two oppositely disposed crescent shaped chambers i1 and a2 as particularly shown in Figs. 5 and-9. Inlet ports a? opening into the crescent shaped Working chambers, pre erably at a. in the longitudinal center thereof, are provided for each as shown in Figs. 5, 7 and 8.

The feed head c is. provided with an entrance chamber c* having inletsf.l5 through the head; and a longitudinal recess@6 in the vhead 'cin which a pin 0? fixed in the casing isvadapted to slide, forms a guide for the head to bring the inlets c5 off the head into register with the inlet ports a of the casing. Exhaust ports u? opening into each of the working chambers, preferably at (is in the longitudinal center thereof are provided for each of the chambers. A f Y Three paddles dzseated at equal distances froineach other Within slots in the runner are adapted to move radially into the workingchambers in a well known manner. The operation of the motor will be readily unratented Dee. e, 1910.
