Holsi-ING AND CONVEYING MACHINE.

SPECIFIUATION forming part of Letters Patent N o. 701,887, dated .T une 10, 1902.

i K 'Application filed September 2,4, 1901. Serial No. 76,359. (No model.) i

To all whom'itmay concern,.-

Be it known that I, SAMUELJACKSON, of Fayetteville, in 'the county of Onondaga, in the State of New York, 'have invented new and useful Improvements in Hoisting and Conveying Machines, of' which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. v

This inventionvrelates to. bucket hoisting and conveying machines. My objectv is to prod uce'a machine by which the buckets containing earthused. in dredging may be hoistedand conveyed to any point desired. Y f My further object vis to improve the detail construction and general utility of such machines and to that end my invention consists in the several new and novel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings,in which- Figure 1 is a side View of my machine complete mounted upon a trackway upon which it is adapted to travel. Fig. 2 is a top plan view of the interior of the machine, showing the working parts and showing in dotted lines the axle and wheels which support the platform upon which the superstructure of the machine is mounted and also showing upon one side a portion of the iioor broken away to show the operating-gears beneath. Fig. 3 is a view on line m x of Fig., 2. Fig. 4c` is a section on line y y of- Fig. 2. Fig. 5 is a section on line ze of Fig. 2 looking at the rear or to the left of the machine, omitting to show the engine and boiler back of it. Fig. 6 is a top view of the central portion ofthe platform, showing a post having a ballway in its upper 'end and balls mounted therein, which` forms the bearing for the central portion of the superstructure. Fig. 7 is a top plan viewV of the forward end of the platform, showing* a portion of the circular rackanduthe gears` which engage therewith and which gears are secured to the floorof the superstructure, the

responding parts in all the views.

Ais the superstructure, comprising a frame having a floor and roof. mounted upon the the platform, as will ,hereinafter be more fully set forth. Uponone end of the superstructure I erect an` upright 1, and 2 is a slotted arm pivoted, as shown, having a pulley-wheel 3 at its outer end, over which the hoisting-cable 4 passes in the ordinary way. The outer end of the arm 2 is adj ustably supported in any ordinary and well-known manner, so arranged that the free end'of the arm Zmay be raised or lowered, as desired.

- B is a truck comprising ordinaryframejspeciiied. The said trackway is secured to the top of the platform 5 by bolts 12- or inany other suitable manner. At the central point upon the platform and within the trackway 8 I mount a post 1 3, having a vertical yopening 14 therein, and 15 is a shaft mounted and adapted to rotate therein, having a bevel-v gear 16 at its lower end adapted to engage or mesh with the gear 17, fast to the shaft 18, suitably supported in the bearing beneath the track, and which in turn has upon its ends the gears19`and 20, respectively. The

' gear 19 is adapted to mesh with the gear 21,

which is mounted upon the axle 6, and the gear 20 is adapted to engage with a gear 23,

mounted upon the axle 6, the wheels 7 being `mounted upon the axles inthe ordinary way, sonthat the retation of the shaftlin one direction will'turn the axles in'one direction, so as to imparta forward movementto the wheels, and a reverse rmovement-.v vlould impart a rearward movement to the -`wheels, thereby enabling me bythe power within the superstructureuto impart locomotion to the truck.

A series of rollers or wheels 10 are secured in a circular lineto the bottom of the superstructure', which wheels bear upon the tread 9 of the trackway S, and the bottom of the center of the superstructure is provided with a plate 25 and has a depending sleeve 4which bears upon the balls in the top of the post 13 and rotatably supports the center of the superstructure.

The upper end of the shaft l5 is provided with a gear 26, adapted to engage with the gears 27 and 28, mounted upon the central main driving-shaft 29. The gears 27 Vand 28 are provided with flanges 30, in which are mounted frictional clutches, which clutches are operated by an arm 3l, traveling upon a cone 32. The cone 32 is operated longitudinally upon the central shaft by a rod 33, which is operated by an ordinary lever 34 in front, so that by moving the cone forward the frictional clutch which is mounted on the shaft 29 will engage with the gear 2S and produce a rearward movement to the truck, whereas when the cone is moved rearward it engages with the gear 28 and causes a forward movement of the truck. I do not further describe this frictional clutch, for the reason that it forms the subject of another application.

In the forward portion of the superstructure and in the bottom or floor thereof I vertically mount a shaft 35, having the gear 3G upon its lower end, which is adapted to engage by intermediate gears with the gear 37, which in turn meshes with the teeth ll7 so that by the rotary motion of the shaft 35 a rotary motion is imparted t0 the entire superstructure and from thence to the arm 2, which allows the bucket to be dumped upon either side of the track.

Secured to the upper end of the shaft 35 is a gear 26', which meshes with gears 27 and 28, placed upon the main driving-shaft 29 in reverse positions and between which upon the shaft 29 is placed the cone 32, which is operated by a rod 33, secured to an operating-lever 39. rIhe inner end of the rod 38 is connected with the cone 32, and as this cone is moved back and forth upon the shaft it brings the frictional clutches (not shown) into operation with the wheels 27 and 28', according to the direction in which it is desired that the platform or superstructure shall turn.

To the lower end of the lever 39 I secu re a rod 40, which has a short arm 4l, one end of which is connected to a shoe or brake 42 and the other end to a strap 43, so that as the lever 39 is moved to and fro it will alternately grip and release the shaft 35 when it is adapted to reverse the movement thereof. It will be observed that when the handle 39 is in a vertical position the arm 41 will stand in alinement with the strap 43 and cause the shoes 42 to engage with the shaft, and thereby hold it frictionally from rotation; but a movement in either direction upon the lever 39 will release it and throw the gear 20 into engagement either with the gear 27'0128. A rod 44 is similarly connected to a shoe and similarly engages with the shaft l5 or, more properly speaking, with the hub of the gear 26 upon the shaft l5.

Within the superstructure and upon uprights 45 I mount a shaft 46, carrying a Windlass 47, upon which the cable 4 is wound or unwound in hoisting or lowering the buckets. Upon the shaft 46 is a gear 47', engaging with a gear 4S, mounted upon the shaft 49, which is likewise mounted in the uprights, and 50 is a gear mounted upon saidshaft 49, adapted to engage with the gear 5l, mounted upon the central shaft 29, and inasmuch as this gear 5l is operated by a frictional clutch, hereinbefore referred, to I will not describe it further.

52 is a rod connected with a handle-lever 53, by which the frictional clutch is operated in order to cause by the intermediate gear the windlass 47 to operate. iVhen thrown out of gear, the weight of the bucket (not shown) is sufficient to cause it to unwind.

C is an ordinary boiler connected to the engine D, which operates the central shaft 29.

To the rod 52 a lever 54 is secured, the lower end of which is secured to a shaft 55 for the purpose of imparting a slight oscillatory movement to it, and upon this shaft 55 is an arm 56, adapted to engage with an arm 57, to the upper end of which is secured a shoe 5S, adapted to be brought in frictional contact with a wheel 59, mounted upon the central shaft 29. This is for the purpose of regulating the speed of the windlass.

Upon the rear end of the superstructure A, I mount a vertically-adjustable counterbalance GO, providing any suitable means for allowing it to be raised or lowered upon an upright 6l and connected to the cable 4, passing over a segment U2, having a guide-groove.`

As seen in Figs. l and S, the arm 6l iand segment G2 are formed integral to each other, being pivoted at G3 to the upper frame-bars of the superstructure A, the counterbalance being secured to the lower end of the upright 6l. The segment G2 extends above the pivotal point G3 and is loosely connectedto a piston-rod G4, the piston being movable in a suitable air-chamber (55, preferably mounted on the top of the superstructure A, said air` chamber being provided with an air outlet or vent G6 intermediate the opposite ends of the chamber. The end of the air-chamber opposite to the connection of the piston-rod with the segment 62 is preferably open for preventing the com pression of air during the elevation of the counterbalance 60, the purpose of the air-vent GG being to permit a free movc mentof the piston within the chamber during a portion of the downward movement of the counterbalance GO and for forming a cushion in said chamber when the piston is moved beyond the vent GG, thereby preventing any jar or strain tothe apparatus should the weight descend rapidly. One end of the cord 4 is connected to the arms Gl, being guided in the groove of a segm'ent, and is then passed over suitable idlers G7 upon the upright l and around the idlers 3, the opposite end being secu red to the reel 47. A suitable tackle-block IOO IIO

68 is suspended by the cord or cable 4 and is provided with means for engaging a hoistingbucket or other load which it maybe desired to elevate or lower. u

The boom or arm 2 is mounted upon the end of the superstructure opposite to the counterbalance, 60 and is adapted to be raised and lowered bya suitable cable 69, having one end secured to the upright 1 and its opposite 'end passed over idlers 70, one being mounted upon the standard l and the other being connected to the arm 2.
