BAILING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 638,948, dated December 12, 1899.

Application filed October 25, 1898; Serial No. 694,551. (No model.)

My invention relates to deep-well hailing apparatus, and has for its object to provide a portable apparatus adapted to be operated by horse -power for effectually controlling the elevation andlowering of a bailer, the various movable parts of the apparatus being actuated by meanswithin reach and underthe control of a single operator.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of an apparatus constructed in accordance with my invention. Fig. 2 is a vertical section of the same, showing the tilting shaft elevated. Fig. 3 is a plan view, partly in section, to show the means for adjusting the bearing-rolls with relation to the master-gear and the means whereby the strut-supports of the tilting shaft are mounted upon the standards of the frame. Fig. 4i is a partial vertical section at right angles to the plane of Fig. 2 to show the stop-pawl and coperatin g means for preventing the backward movement of the bailer during the elevation thereof. Fig. 5 is a detail sectional view of the connect-ion between the rear ends of the bearing-block braces and the standard of the supporting-frame. Fig. 6 is a similar view of the connection between the bearing-block and the front ends of the braces. Fig. 7 is a detail vertical section to show the means of adjustment for the bearing-roller-supporting frame. Fig. 8 is a detail view in perspective of the adjacent extremities of the operatinglever, draw-rod, brake-lever, &c.

Similar reference characters indicate corresponding parts yin all the iigures of the drawings.

Mounted upon a suitable truck or supporting-frame 1, which may have supportingwheels to adapt it for movement to and from the point at which the apparatus is to be used, is a horizontal master-gear 2, upheld for movement by supporting-rollers 31, mounted upon said truck or supporting-frame, and mounted upon a suitable superstructure rising from said truck or supporting-frame is a tilting drum-shaft 4, having a pinion 5, of

which the teeth normally mesh with those of the master-gear, said shaft being mounted for swinging movement toward and from the plane of the master-gear. Said superstructure includes standards 6 and 7, rising from the truck or supporting-frame, and an up-` provided at an intermediate point with a rigid depending bifurcated arm 14, pivotally mounted upon the frame-bar 12, and to a bearing-block 15, in which is mounted the ,other trunnion or gudgeon of the drum-shaft,

is connected the extremity of said operatinglever by means of links 16, which are rigid with the bearing-block, whereby in moving the free or handle end of the operating-lever the bearing-block 15 travels in a path approximately concentric with the opposite extremity of the drum-shaft to avoid twisting or straining that trunnion or gudgeon which is mounted in said bearing-block. Also the said links 15' form lateral guides which operate upon opposite sides of the front end of the frame-bar 12 to insure the reciprocation in a truly vert-ical plane of the bearing-block 15.

Mounted for reci procatory movement upon the frame-har 12 is a slide 17, itted in suitable 0"uides 1S and provided with a stop or enlargement 19, which is adapted when the slide is extended for arrangement in the path of a shoulder 20 on the bearing-block 15, whereby said stop forms a lock to securethe bearingblock in its depressed position againstvvertical movement, and thus to effectually maintain the teeth of the pinion 5 in operative engagement with the teeth of the master-gear. Connected at an intermediate point with the IOO slide is a lever 2l, mounted upon the frame and having in connection therewith an operating-rod 22, which terminates at a point near the vertical plane of the rear end of the operating-lever 13, whereby said operating-rod may be grasped with facility by an operator positioned to manipulate said operating-lever.

The drum-shaft 4 carries an armed drum 23, to which is attached one end of a bailer-cable 24, said cable extending at an intermediate point over an elevated direction pulley or sheave 25, supported by a derrick 26 or other equivalent frame, and also arranged upon the drum-shaft, preferably contiguous. to the drum, as illustrated in the drawings, is a brake-wheel 27, encircled by a contractible brake-strap 28, with which is connected one arm of a brakedever 29, also located within reach of an operator positioned to manipulate the lever 13. Inv the construction illustrated the brake-lever is provided with an intermediate spindle portion, which is mounted in a bearing located upon the upright 8.

To maintain the bearing-block 15 in its proper position with relation to the other elements of the mechanism, I employ pivotal' to swing in vertical planes when the hearingblock is elevated and depressed. Said tapered keys may be adjusted to vary the forward4 pressure of the braces 30 and are adapted to be secured at the desired adjustment by means of pins 34, engaged with openings in the keys and bearing against the inner surfaces of the braces. To maintain lthe bearing-block and strut-braces in their proper relative positions, I em ploy tension-braces 35, extending from said bearing-block rearwardly to and through the standards 6 and fitted at their rear edges with adjusting-nuts 36. Also carried by the drum-shaft is a stop-gear 37, of which the teeth are adapted for engagement with the extremity of a pivotal stoppawl 38, mounted upon one of the standards 6 and normally held in an elevated or inoperative position by means of a liexible connection 39, consisting of a chain, cable, or equivalent thereof extending over a suitable guide 40 on the crossbar 11 and adapted for engagement at its rear end with a holding device or catch 4l. By disengaging the connection from the catch the stop-pawl may be lowered to arrange its free end in operative relation with the stop-gear, whereby during the elevation of a bailing-bucket the disarrangement of the operating-gears will not cause the dropping of the bailing-bucket for the reason that said pawl will lock the drumshaft against backward rotation.

Arranged in operative relation with the inner periphery of the rim of the master-gear for holding the latter against vibration upon its seat (formed by the above-described supporting-rolls) are bearing- rolls 42 and 43, which are mounted in pairs upon forwardly and rearwardly adjustable frames, each consisting of upper and lower transverse bars 44 and 45. These adjustable frames, between the extremities oi the bars of which are mounted said bearing-rolls, are connected with the standards 6 and 7, respectively, by means of adjusting-bolts 46, and inserted between said frames and the contiguous surfaces of the standards are wedges 47. By loosening the said bolts and suitably adjusting the wedges fthe frames may be moved either toward or from each other, which adapts the rolls at the extremities of the frames to be moved in pairs in parallel chords of a circle formed by the master-gear. Thus it will be seen that these rolls are adjusted obliquely to a radius and as may be necessary in connection with the rim of the master-gear to insure a closer bearing or reducing the pressure, and thus confine the mastengear operatively in the desired position upon the supporting-rolls. Also connecting the standards 7 and terminally overlapping the rim of the master-gear is a retaining-bar 48 to prevent the vertical displacement of said gear.

The master-gear is adapted to be operated by horse-power, and a simple means whereby such power may be'applied to the mastergear consists of a sweep 4t), of which one or more may be employed,v pivotally mounted at its inner end on the outer face of the master-gear for vertical swinging movement, provided at its outer end wit-l1 a suitable elevis 50 for the whifiietree to which the power is applied and held in the desired position against forward displacementunder strain by means of a tension rod or brace 5l, while the whiftletree supports the outer end vertically, yet permits it to yield as may be necessary to conform with the height of the animals hitched thereto.

In operation the tilting shaft, by which the pinion 5 is carried, may be elevated to disengage said pinion from the master-gear to allow backward rotation of the drum, and such backward rotation may be controlled as to speed by means of the brake mechanism hereinbefore described. Also when the tilting shaft is depressed and the receiving-gear or pinion 5 is in operative engagement with the driving or master gear 2 the slide 17 may be moved forward to lock the forward bearing of said shaft in its depressed position, and during the elevation of a hailing-bucket the stop-pawl 38 may be released to allow its free end to drop into operative relation with the stop-gear 37, whereby accidental backward rotation of the drum-shaft is prevented.

It will be seen from the foregoing description that I have provided a simple, comparatively inexpeusive,and efficient apparatus for bailing purposes which `may be moved by IOO TIO

horse-power to the point of use over a well to be bailed and of which the operating parts may be controlled by a single attendant lo.

cated within reach of the operating-lever 13, and also of the operating-rod 22 and brakelever 29, and it will be understood, furthermore, that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the construction illustrated the derrick consists of a plurality of timbers separate from the supporting-frame of the operating mechanism, suitably connected at their upper ends and adapted to rest at their lower ends upon or be embedded in the soil, said lower ends being spaced from the supportin frame or truck of the mechanism at such a distance as to allow the animals by which power is communicated to the master-gear to move under the derrick-beams or within the circle described by the lower ends of said beams. This construction provides for lightness, and hence increased portability, of the operating mechanism, While giving the operator the necessary control of the various movable elements of the machine. Furthermore, it will be observed that by the use of an annular master-gear having its center wholly open I am enabled tomakeitof asufliciently large diameter to obtain a firm and steady bearing upon the supporting-framework-and at the same time allow the bailer-cable to operate therethrough, and thus economize the space required in which to operate the machine. The drum also is located at the longitudinal center of the framework, and hence the upward strain applied thereto in the operation of elevating the hailing-bucket is approximately in alinement with the center of the structure.

In operation a hailing-bucket of the ordinary construction is lowered by means of the cable and operating devices into a well, is filled with the sand or other material contained in the well, and is withdrawn therefrom in order to put the well into condition for further drilling or for pumping. The operation of bailing a well is so well known in the art as to require no more specific statement.
