In' Umso-drawings, the lnumerall 2 desig- .nates'the cylinderof the iifiotoi",whosebther- ..Wise open enlsrare res ectfivel'y closed-by Athe communicates wit admission head V3 'an the exhaust, head1-4.
'The cylinder -has formed therein a' iston chamber .5, whichis eccentric with re ation tof the longitudinal axis of the cylinder. Al'n 'the thicker portion ot'thc walls of this cylinder aro formed two longitudinally cxtendingorts O and 7, the port 6 being preferabyan admission port, and thel port 7 being an' exhaust ort. Each of these orts hlthe interior ofthe piston chamber' at a plurality of points throughoutiits len th by means of the .cross-ports 8. Each o the admission and exhaust heads is formed with a shoulder or rabbet 9 to receive the end of the cylinder, the parts bcr lthat Y details ing detachably secured together byinea'ns o f the tensionrods 10. These rods are' seated in longitudinallyextending' grooves 11,
the f cylinder4 and heads,` their downwardly bent ends whichseat. in the deepened grooves I in the-cylinder heads being` secured by heads or nuts 12;-- These rods forni a simpleir'nd secure means of holding the parts toget ier.
13fdesignates a piston shaft,'which eX- tends eccentrically through the chamber 5,
and whichcai'ries a single piston blade 14 which -is arranged to slide freely through the diametrically extending slot inA the shaft in.
which'it, is seated, the cross-sectional form of the cylinder 5 'being such that both edges of thepiston blade 'will maintain contact ,therewith during` the entire revolution.A -Tlie forward 'end of thel piston'sliiiftis provided .1 with av bearing in vthe exhaust head` 4, and extendsthrough andbey'ond said head, termvi'nating at.' its outer end in the-.threaded portion 15 adapted for connectionwith' the'tool Whichis to`bedrivfenby'the motor.'
The rear end of the shaft 13 has a. journal 'portion 16 which has its bearing in a splitushing 17, which is seated .in the admission head 3. This'bushing has formed therein a through-port 18, which communicates at its .foiward end with the' admission port (l ot the cylinder, and which. opens at. its're'ai end into an air space or chambei-IQ in the rear portion of the admission head 3. Said bush- Ving-is-'also cut away'or .slotted as shown at v20 in;Fig. .Z, to receive a thrust. collar-Q1 oir the rear'end.of the pist-on shaft. lhe slot or cut-away portion in the bushing is innde of greater area than the thrust collar so as to provide an adjacent air spaee or chamber, which .communicates` with ,the atmosphere through a slot 22 in the head which coininunicates' with the. slot or opening Q0. This bushing is secured against. rotation by its engagement with the tension rods in .the manner shown in Fig. 5. i
23 designates a lubricantl opening in thc head 3. which communicates wilhvthrl air chamber lil. :ind which is noi'uuilly closed by a spring-.seated i'alvc 24. Oil introduced through this opt-ninar enters ihe chamber 19, and is carried by the air into the cylinder and finds its way to the bearings for the piston shaft., thereby keeping the parts properly lubricated. .\ny other suitable lu- 'whichare formedv in the exterior'snrface of Utl 'moeive the threaded exhaust.

end of thisipe 26' is eirtend'ed into-the 'charnformed' with a plurality ofperforations 27. which act as a strainer forthe air to-prevent foreign matter from-being carried with the air into'the motor.l v
The exhaust. head f4 is formed with a longitudinally extending exhaust port 28. which opens to-.tbe atmosphere at its forward. end and communicateswitli the exhaus't port 'I of the c linderat its rear end.
20 We may also provi e. the -wall .of the exhaast ort 7 with a phir'alit of exhaust passa es g* to 'provide an ,additionalgmeans of. ex aust. In some cases, these passages may entirely-take the place; of the exhaust ort' 25 28 through the head 4. They are especially advantageous insmall sizes of motors where there is not sa'oient room in the cylinder wall to make exhaust passage Z of lar e enough area Ato otherwise take care of te The operation of the motor will be readily understood. The air enters thepiston I'chamber through the-crossports 8 and exthe provision of a plurality of these crossf ports extendingfthroughout the4 length of the cylinder, air fis supplied lo and exhausted from; the iston chamber s imultaneously 40 throughout its length, thus obtaining a4 much.`quicker admission and exhaust.k The o erationma however, be reversed, and te .air or ot er.tluid be brought into the motor -through the port 7 and exhausted through the port 6.
.Tlieiadvanta es-ofour invention result from the simp icity of construction, there being com aratively A'few arts, which are easily. ma e and assembled), and whichare V held to ether i-n such a manner that they canbe rea ily detached'ivhen necessary. lViiile adapted for a variety of purposes, this inotor has been vfound in practice to be especially 'adaptedforuse in driving boiler tube '55 cleaners of that class in which' the motor is carried through the tube to be cleanedwith, the cleaning tool which. is attached to the projecting` end of, the iston shaft.' The compact arrangement o theparts enables 60 the motor to be readily constructed lfor this urpose, while the manner iti which the air is discharged enables the latter to be utilized forblowing the material loosened by the tool out of the tube bein cleaned. It 4will be noted that the piston s aft isnot only propted' tobe-con'nected to a' hose or othersupplypipe -for'adinitting Vair or otherftluidtothe motor.. The inner this -.extended end '.portion is conditionfThe front bearing i,oos,056

The provisionof the a'ir chamber andvent adja.` cent to the rear bearing of thepiston shaft is also' a feature of advantage, since the vent relieves 'any accumulation of 'airwhich mghtotherwisebe caused by leakage ast the shaftbearin' Another advantage o this air -chamberan vent. is that the air which leaks .by the bearing will carry with it sutlicient lubricantf to keep the`rear .bearing in proper will at all timesbe kept` lubri cated by t leakage of the ariinden pressure, carrying the lubricant with it.
