This invention Vrelates to a new and useful improvement in motors for drills, but is adapted tor use in connectioon with automobiles and stationary power plants. The objects ot' the present invention are to simplify the construction and cheapen the vcost of Y production per rated horsepower and to enable the device to readilyrepaired. l

In the drawings, I have shown my iniproved motor as adaptedvto use as a drill in may be used as the mobe easily assembled and ons the motor can be adapted -for iving automobiles or as a stationary use in or engine. l indicates a tlanged cylinder, preferably in the form oit a casting having a valve chamber 2 located to one side thereof and which communicates with the bore ot Cylinder l by inea-ins of suitable openings constituting ports in which operate parts of the valve-operating mechanisinl l is thefront cylinder head. having a threaded boss to which are secured packing nuts for packing the rotatableliollow shaft 6 and providing application and it is obvious that with slight `cylinder inthe ends 'the 'heads of the valve stems 29, the heads of gated openings Y `ent longitudinal movement of each of said stems relative to ated openings chainb serial No. 290,800. f

a bearing for the front end thereof. This casting l extends up to include the valve casing and is provided with an opening' in which is arrangedua hollow valve cap 7 through the opening in which passes the ei:- haust from the front end of the cylinder. 8 is a rear cylinder head having a similar eX- tension for receiving a hollow valve cap 9 through the opening in which exhaust passes from'the rearend of t-he cylinder.

l0 is a hollow piston rod mounted upon the shaft 6, which shaft- 6 may be designated as the driving' shaft, the sleeve or hollow piston rod l0 `being designed to slide longitudinally upon the driving shaft 6 while the latter rotates. ll is a piston head secured in a suitable mounting, preferably by a threaded connection, to the forward end ot `the hollow piston rod l0, said piston head having the usual packing' rings l2. The piston comprising the head and hollow rod l0 are intended to reciprocate within cylinder l and passing' through the packing nut mountedon the rear cylinder head 8, the pistonrod l0 extends into a chamber formed by acylinder 13 secured to the rear cylinder head 6. This cylinder 13 is closed at its rear end byvmeans of a head 14 and is eX- teriorly threaded to accommodate a capped sleeve l5 having handles 16 by which the drill may be fed, as when boring through 'metal and thepoint at the rear end of the cap piece is placed under al lazy mani l do not. deein it necessary in the present to disclose the operation of this feeding mechanism as thesame is disclosed in Patent No. 1,369,256 granted to me Febwhat is known as ruary 22, 1921 `Chamber `2 is connected manner to a source ot air n yin any suitable or steam supply .and located within said chamber is a rocking valve.. parts of which are best shown in Figure 4C. 28 Vindicates an open ended ofl which are arranged said valve stemshaving longitudinally elonto permit a slight independtheir supporting connecting niember 28;' ilhe cylinder 28 is provided with openings registering with the elonginthe heads of the valve stems and through'these openings are passed pins 30, 'see Figure 3, which pins extend up into ers arranged abovethe valve casing and having'seatsorsaddles formed in their' upperfends for receiving the locking member or' a spring follower 31. co-operating with a spring` 32 bearing against a semisplierioal rocker 33 seated in a cap piece arranged in an extension ot the valve cha1nber, -as shown in Figure 3. The purpose or' this construction is to cause the cylinder QS, when it is rocked past a position of deadcenter, fto be carried the iremain'der .ot its rocking movement under the impelling 1aetion of springs 3Q, or' which there are two, as shown in Figure 1, arranged at each end or cylinder 2S so that theirfcombined action on cylinder QS Willbe exerted with the `least possible torsional strain `on the cylinder 'which is thus substantially balanced. VThe cap pieces 34 -are `formed with recesses in which the upper ends ol' rods connected to .the .springseats 3:1 yand which lslide through the semisph'erioal 'heads' 33, may 'operate "as the cylinder is rocked from one fpositifonto another` The are otmovement is :slight but in the position of deadcenter thevrlods project slightly above the semispherieal-spring seats 83 and the space in the cap pieees34 `is provided to accommodate this projection of the rod through the spring seats 38 The bore of the valve chamber 2 is slightly| enlarged at each endto receiveandlseat `valve seats 35 against the 1inner faeesro'f which 'operate fthe intake valves 36. These intake valves are provided with "projections 36u', see Figures 4 and'8, whic'hoperate'innotches 28 in cylinder 28 there being "sulieie'nt space in said notches `to permit of ylost motion so that the valves 36 are only operated -a short distance near ythe `end 4ofthe movement of Vcylinder E28. The cylinder 2,8 is spaced. apart `from the valve easing by means 'oi lugs lb andthe heads on ythe ends ot the valve stems 29 bear against the `lugs MS56, there being a spring 37 located between said heads so asto Ytorce a o'hamerenad shoulder on the valve stem against "the valve seats 35 tending .to press `them outwardly or away from each other. `mt vard pressure is resisted by a sleeve 38 which kis located between the valve seats 35 (for- .the intake valves) and the valve s eatsgfy (ortheeirhaast). rEhese valve :seats 3,9 arehel'd in position by the piston heads-'4and 8, respectively, together with their valve fcap, 7 and 9. The valve seats .39.' are ,-provided vvith blind bearings in vvhichltheouter endsofthe valve stems 29 are seated, the valve stems providing 'a Vmount for the exhaust valves 40 which bear against the seats 39. These `valves 40 are provided with lugs 40@ between which are looatedroclr arms 4lj (see Figures and 4) the lower ends otsaid rock arms being birurcated or forked Yfor (purposes to be hereinafter described. `The upper side orA valve 40V is provided With-fa lug lor projeeton 0b @per-atlas a a revocare `,n/tbe aspline, (see Figure l) 4the prongs of the of .the cam faces 1l yand as the piston is held :rock-er arms 41 on a'valve said valve stem to be rocked and with it operated to sleeve-38 to limit or determine the oscillat ing movement ot valve 4() so as to insure proper' registration of its openings with the openings in the valve seat 39 and also the 'proper closure thereof. A pin 42 serving as holds the valve seats B9 in proper position.

45-indicates rocker plates ar 1anged at-each end of the cylinder l, (see Figures l and 2) which rocker plates are provided with project-ions 45a which enter the space between valve rocking arms 41.,.said arms being pinned or otherwise fastened to plate is also provided with a cam liace 45b forming one Wall of an opening or recess therein with which cam face (zo-operates a c ain projection 112L on the piston head. There are tour cam faces on the rocher plates with Which the four cam projections 1l"qu cof-operate. The operation or the vvalve mechanism is as follows:

As the `piston reciprocates rearwardly one carried thereby will on the rocker platet against rotary movement by the cross-head .19, the rocher plate 45 will be operated so that the linger 45L thereof engaging one of the biturcated stem will cause engage a cam face 45b the. sleeve 28. lVhen one or the rocher arms 41 is operated by finger 451L of a corresponding rocker plate 45, a corresponding en Ahaust `valve 40 and a corresponding valve 4stem 29 `'are operated. The enlarged ends of valve stems 29 being seated Within each yend el? sleeve 28 and operatively connected thereto by pins-30, sleeve 28 will be rocked at every operation of: either one of said rocker 'arms to aetuate intake valves 36 sinmltaneously with the positioning` oiA ez;- haust valves 40.

Thus, when one of the rocker arms 4l is operated "to exhaust cylinder l, the corresponding exhaust valve 40 is positioned so as to have its ports in register with the ports on the stationary seat 89, whereby the luid can pass from that end or the cylinder lthrough the aligned ports or exhaust valve v4() and seat39 and then t rough theopenin;

inhead 7 or 9 into the atmosphere,

Upon the operation or sleeve 2S, inlet valves 36, by virtue of the 'act that lugs a projecting from said valves occupy notches 28a formed in the ends ot saidy sleeve, will lbe operated simultaneously so as to post tion oneA of said inlet valves so that the ports formed therein'are in register with yports formed in the corresponding stationary valve seat 35 and the steam or air can passvlrom` chamber 2 to one end oilcylinder 1'. The Vother of said inlet valves is move out of cooperative relation with itsystationary seat Brse that the openment of said arms ings formed in said inletV valve 36 and its respective seat 35 are. out of alignment with each other and the fluid cannot enter this end of cylinder l.

Simultaneously with the operation of intake valves 36a exhaust valves i0 are actuated. so that each one oit said exhaust valves cooperates with its correspondingintake valve, whereby when one of the intake valves 36 is opened, the corresponding exhaust valve l-O is closed, and vice versa. Exhaust valves a() are looselymounted on valve stems 29 and are operated by rocker arms il by means of lugs 40d which project outwardly from said valves and are disposed to each side of arms el and lie in the path oi' movement thereof. p Iiugs l-Oa are spaced trom each other a sutticient distance so that arm al. has a predetermined amount of lost motion With respect to valves 40, whereby said valves are actuated during the iinal move- V and receive snap action under the influence of springs 32.. IvVhen the springs 32 are compressed andv move past a position ot' dead-center, the energy stored therein Will cause the sleeve 28 to he rocked the remainder ot its intended distance, which is determined by the lugs or projections on the intake and exhaust valves, respectively. In the operation under consideration, the rearward movement or the piston will cause the exhaust valve at the rear endl of the cylinder to be closed, i. e.5 its ports, and thrown out of register with its valve seat and inlet or intake valve 35 at the rear end of the cylinder to be moved to a position Where its ports will be throivn into register Vwith its valve seat 86. The compressed air or steamivhich is admitted to the space around the cylinder 28 Will pass through the notches 28a and thus be enabled to pass through the registering openings of the .intake valve at the rear end of the cylinder7 then by virtue ot the pressure thus admitted at this point the piston will be caused to move forward. Coincidently with the reversal or the valves at th end of the cylinder occasioned by the piston reaching the limit of its rearward stroke, the valves at the forward end of the cylinder will likeivise be reversed because of the connection of the cylinder 28 therewith; so that the intake value will be closed and the exhaust valve opened when the piston starts on its forward movement, Upon leaching` the forward limit of its movement, the piston will engage the rocker" plate mounted on the forwa rd cylinder head to close the exhaust valve at the forward end ofi the cylinder and open. the intake valve at that ond and, through `the means above described, 'open the exhaust valve at the rear end ot the cylinder and close the intake valve at the rear endf The purpose of providing lost motion in the throw of the valves is to reduce the arc of their movement from an open to a closed position and at the same time give a greater arc of movement to enable the springs 32 to act in snapping the valve cylinder 2S from one position to another so that said springs may be operated eiliciently.

.3y the employment of my translating device for converting reciprocating motion into a rotary movement, it Will be observed. that dead centers are impossible, it making no difference Where the piston stops-the admission of pressure will cause the piston to move and start the shaft to rotating.

By providing a plurality of ports in the valves and arranging a lost motion between the valve operating the cylinder and the valves, the valves are moved a relatively short distance While the cylinder 28 operates through a greater arc of a circle, thus enabling` the springs to store up energy in passing over a dead-center position thereby effecting a quick snap action in opening and closing the valves. Furthermore, the valves being seated on the pressure side of the valve seats will be held by the pressure to their seats and be constantly ground in osition so that they Will have a tight lit at all times.

I do not in this application claim the means 'for converting the reciprocating motion of the piston into a rotary motion, as the same is shown and described in a companion application led by me November i4, 1919, Serial No. 338,068.
