DRIVING MECHANISM. 5

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and -useful Improvements in Driving Mechanism, of which the following is a specification.

This'invention relates to the construction and organization, in combination, of various mechanical features and. devices for en porting a driving-shaft and effecting its e cient and continued lubrication; and it has for an object to provide a simple compact structure in the nature of a driving-head for supporting and lubricating that end, more especially of a driving-shaft, to which the power for effecting its rotation is applied.

A driving-head constructed in accordance with the present invention possesses means, combined with supports, in which the shaft is mounted for lubricating the various rubbing surfaces bya system of forced lubrication, thecirculation of the lubricating material being preferably through a closed circuit. Usually there will be combined in my im- 1 .proved form of driving-head with a sectional shaft a couplin device, whereby the portion or section of t e drivin -shaft from which power is taken ofi may e driven from the power-actuated section of the shaft, even though these two'sections are not.in alinement or in parallelism one with the other. A driving-head constructed and organized according to the present invention has, moreover,-its various mechanical details so combined with and related to each other that the assembling and the taking down of. the various parts are facilitated.

'In the drawings accompanying the pres- -ent specification a driving mechanism or head embodying the features of my present invention is set forth, Figure 1 therein illus-- trating, partly in plan view and partly in horizontal section, such a driving-head. Fig. 2 is a longitudinal vertical section taken on the plane of the line 2 2 in Fig. 1, certain of the parts being shown in elevation, however.

In construgt ngla driving-head emb'od g e present invention. t ere will usually be a pro er sup orting-frame in which the driving-shaft wi 1 be mounted. This sup orting-frame is herein by B anrf may constitute an inte ra'l part of the frame of the mechanism, mac 'n'e, or apparatus to which the present device plied, orit may constitute a subframese'parate and distinct from such main frame and secured thereto or affixed in place independ- It will usually comprise a base portion, such as 2, upon which there is erected an upr'ight 3, having a journal portion 4, affording a bearing for the drivingshaft.

' There will preferably be provided'in the( present driving mechanism or head an organization whereby the main section of the drivsatisfactory turning movement, even though that portion of the shaft to which the driving be driven with a smooth and designated is ap- 3 power is applied is so disposed in its bearin s as to be out of alinement or out of paralle ism with that section of the shaft from which power is taken. For this purpose the driving-shaft KOO (designated herein In a general way b S) is sectional, the section szconstituting In this ease the one from which power; is taken, be-

mg mounted in the bearing portion 4 of the upright 3. The other section s, or that section to which the driving power is applied, is suitably mounted at the other or outer end of the head, the two sections being connected one with the other by a coupling, a suitable form of which will be presently described,

P designates a driving-pulley driven by a belt from a source of power, (npt herein shown,) this pulley being secured in this instance to the outer end of the driving-shaft section 3: 'In order to form a firm support for the section 8, the bearing, therefore, is preferably elongated and advantageously extends some distance into the bore of the pulley P. In fact, the bearing may be so K the section-is reduced in diameter (see 5) and the pulley is attached by a key 6 to such reduced portion, being held in position against the shoulder formed by the reduced portion by the usual nut and washer 7 and 8, respectively. Ofcourse other means may be'empl'eyedf'or the attachment of the pulley to its shaft-section.

Inorder to enable the two sections .5 and s of the driving-shaft S to be readily coupled one-toanother and at the same time permit the section a to be supportedin a proper journal-bearing, which preferably extends substantially throughout its entire length, I prefer to form the bearing for this section in adetachable'movable member, which maybe removed f'rom the head'in order to permit the assembling ofthe shaft-sections and their connecting-coupling; This removable or detachable member is desi nated herein by C,

and the means for detac ably connecting it with the head may be any appropriate for the purpose. A's constructed in this instance the attachment of the two is made by means of a so-calledinterrupted or mutilated, screw, portions of the thread 0 on the member measured axially thereof and extending peripherally through a considerable distance (see thereduced sections-c) beingremoved, Whilethe bore ofthe opening in the head with which the member engages is corre spondingly formed in the usual and wellknown manner. The member C is shown 'provided with a flange 9, forming a shoulder 9, preferably adapted to make a tight joint with its contacting surface, for a reason that This flange may will' presently appear. have openings 0 for engagement withxa properwrench.

Referring now to the coupling device for uniting the two sections of the shaft any construction thereof suitable for the purpose may be employed. The-form herein illustrated is in its general construction familiar to those acquainted with such devices, although embodying certain features of novelty. Referring particularly to Figs; 6 to,

10, inclusive, the shaft-sections s and s are provided with respective heads 10 and 10', which, through an intermediate piece, are capableof transmitting motion from one'to the other. As shown in those figures, the, head 10 is provided with a cross slot or channel 11, while the head 10 is provided with a pro-. jecting feather or rib 11. The couplingpiece, adapted to en age, respectively, with thechannel 11 and t e feather 11 1 and serving by reason of such engagement totransmit motion from the shaft-section 8- to the shaft-section s, is designated in a general' I way by C, being formed with a channel 12, adapted to engage with the feather l t and a feather12, extending substantially at right angles to the channel 12 and adapted to engage with vthe channel 11- in the head 10-.

Evidently when the parts areassembled, with their-respective channels and feathers in engagement, the rotation of the shaft-section s will be transmitted to the shaft-section 8, even though the axes of the'twosections are not in line and even though such axes are disposed somewhat at an angle to each other, the respective ribs during this rotation slid ingto and he in the channels with which they engage. In order to prevent the accidental displacement of the coupling-piece C from its proper position with relation to one of the heads with which it engages whenthe shaft-sections are disassembled, it is here combined with means for securing'it toone of said heads, although not in a manner to prevent its proper working. In this case it is adapted to be secured to the head 10 by means of a screw 13, engaging with atapped opening in such head, and the shaft-section s to which the head is afiixed, the-opening' in which the shank and head of the screw are located being sufficiently large to permit the free and'necessary play of'the coupling-piece.

of the head 10 of the coupling when the parts are assembled, whilethe outer radial face of the elongated bearing in the member C is also in close relation with the radial face of the hub of the pullev P;

The frame B is in the illustrated construction shown provided with an annularexten? sion 6, encircling and substantially concentric with the shaft, while in the vertical wall of this extension rearward of the coupling there is a bearing for the sections of the shaft. The end or radial face of thebearing in the wall I) being in close relation to the radial face of the head 10 prevents, therefore,

when the coupling is closely assembled, the axial displacement of the main section 8 of the driving-shaft.

7 There is also shown, combined with t e present driving mechanism, means a lubricating medium to the various ournalbearings supporting the driving-shaft and. for circulating such lubricant in a closed circuit in which such bearing portions are included. As a means for circulating the lu bricating medium a suitable form of centrifin theen wall member 0 extends through 1n the member the lower or base ugal or other pump may be used, preferabl driven from one or the other of the shaft-sections 8 or s. In the construction and organization herein ment, being prevented from rotation by any suitable means, the 'form thereof herein shown comprising a lug or finger 14, extending from the casing of the pump and extending when into a recess between 1n proper position osses or projections 15 15 on of the frame B; The pump illustrated is situated between the shaft-bearings in the rear wall I) and the portion 4.

In order to make a convenient reservoir for receiving the drip from the various bearings, portion of the frame B is shown having-a floor with a depression, the sides of the lubricant-receptacle being formed by the casing E. The suction-pipe 1601 the pump terminates adjacent to the bottom of such depression, while the discharge-pipe 17 from the ump'communicates with a crosspipe 17, i fom which leaders or branches extend to proper points for &c., into openings communicating with the various bearings. In the organization set forth this forced lubrication is directed to a plurality of journal-bearings, that for the shaft-bearing in the portion 4 havingan oilhole 18, immediately above which the dis charge-pi e 18 terminates, while the bearing 1) of the frame extension I) has an oil-opening 19, with respect to which a discharge-pipe 19 is also properly located. The oil-hole 20 for the journal-bearing in the and through a continuation of such opening C, thevtwo passages being in alinement whenthe member 0 is adjusted to its proper position and'the horizontalfeeder 17 havin 1 above suc opemng. The oil-groove 20 in the journal-bearing in .the member C, with which the oil-passage therein communicates, preferably extends to and terminates in that radial face of themember Oagainst which the hub of the pulley P bears in order to Inbricate such surface. A The drip from the joint between the face of the hub and the contacting face of themember C is received for forcing shown the movable element; of this pump, the latter being designated by a fixed portion discharging the oil,

the extension 6 a discharge-opening situatedin a suitable channel v v 1n the resent case formed in part b and in part by a ange 21. The drip in this channel, being naturally thrown outward by centrifugal force toward the bottom of the channel, is returned to the receptacle in the frame B by means of a return-pipe 22, secured in a passage-way 21 in the member 0 and communicating therethrough with the space below the coupling-chamber, which has an opening 0' in its bottom surface, through which the oil discharges into the receptacle. The outer end of the receivingpipe 22 is curved around the axis of the driving-shaft concentrically therewith and terminates in close proximity to the bottom of the channel W in a position above the driving-shaft to receive the oil in the channel thrown outward against the bottom surface thereof by centrifugal force. The casing E, attached tothe frame B, serves not only to form an oil receptacle or reservoir, but also to inclose the various parts of the head.
