MATERIAL-MOVING APPARATUS.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed May 14, 1917. Se ial No. 168,463.

To all whom it may concern:

Be it known that I, HENRY B. SAUERMAN, a citizen the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Material-Moving Apparatus, of which the following is a specification.

My invention relates to improvement in material-moving apparatus of the type comprising, generally stated. an inclined guideway supporting a traveling carriage thereon wth a dumping scraper-bucket connected with the carriage, and a hauling-line through the medium of which the movements of'the carriage and bucket are controlled, my object being to provide a novel, 's'mple and positively operating construction of this general type, in wh ch the bucket is prevented from accidentally swinging to dumping position in the movement of the bucket to dumping position. 7

Referring to the accompanying draw:- ings: a

Figure 1 is a view in side elevation of apparatus constructed in accordance wth my invention for transferring material from one elevat on to a higher elevation, the apparatus being shown in the position it assumes in moving to dumping position. Fig. 2 is a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 8 is a view like Fig. 1, showing the parts of the apparatus in dumping position. Fig. 4 is a view like F g. 1 of another embodiment of my invention. Fig. 5 isa section taken at the line 5 on Fig. 1 and viewed in the direction of the arrow. Fig. (i is a section taken at the line 6 on Fig. 1 and viewed in the direct on of the arrow and Fig. 7, a view like Fig. 1 of still another embodiment of my invention. i

In all of the constructions illustrated I have shown my invention as incorporated in a so-callecl slack-line system the inclined cable-way of wh ch is represented at 8 and in practce wouldbe anchored at its lower end in any suitable manner, and at its upper end supported at a higher elevation and ma manner adapting it to be slackened and made taut at will, all as is well'understood in the art and therefore does not require illustration. r

Referring-more particularly to Figs. 1, 2

and 3. 9 1 IS a carriage which "slidably mounted on the cableway 8 and in the'forno shown comprises a pair of plates 10 and and 11 are grooved pulleys 14 journaled on certain of the bolts 12 and by wh ch the carriage engages the cable-way -8. The dumping scraper, or bucket, represented at 15 and which is'supported from the carrings 9, is ot'a form generally employed its forward, open, digging-end 16 being provided with an edge-portion 17 in practice usually serrated. The bucket 15 is con nected at its rear endas at'eyes 18 at oppos te sides of the bucket with chains or cables 19 oneonlyof wh ch is shown,-which connectat their upperends w'th eyes 20 on the carriage, whereby the bucket is, in effect, pivotally hung from the carriage 9 and at such a point relative to'its center of gravity that the latter will tend normally to swing to dumping pos'tion. The-bucket 15 is connected at its front end with a branch 21 of the hauling-line in the fcrm'of a bridle, which unites w th another branch 22 thereof at a block 23 connecting withthe single section 24 of the hauling-line. Thebucket is also connected at a bail 25 thereon, with a cable 26 in the form of a bridle, which connects at its upper end as ind'cated at 27 with pivoted eyes 28 on a rock-member 28 located between the plates 10 and 11 and pivoted on the lower bolt 12,

the rear end of the branch 22 running over a pulley 29' journaled between the plates 10 and 11, and connecting with the member 28 adjacent the connection 27. The m'ember28 is provided with a projection 80 which in the load-carrying postion of the apparatus rests against a'pin 31 extending at its ends in curved slots 32 in the plates 10 and-ll and movable up and down therein, the pin 31ypassing through a yoke 33 located between the plates 10 and 11 and connected at its upper end with a cable 3 1' which passes over a pulley 35 on the carrag'e,

thence over'a pulley 36 on the block 23 and connects with a traveling block 37 running, at a pulley 38 thereon, on the cable-way 8', thisblockcooperating with a stop 39, prefa purpose hereinafterdescribed.

Theparts of the apparatus are-so con-- erably adjustable along the cable-Way 8,"for V shown in Fig. 1, thus normally holding the bucket in load-carrying position and the bucket cannot swing to dumping position until the member 28 has been rocked to carry the cable 26 forward of said pivot.

In the operation of the apparatus the bucket is dragged along the material to be moved, by drawing on the hauling-line and the carriage pulled along the cable-way 8 to the point of dumping. When the block 37 strikes the stop 39 the block 37 is arrested and continued movement of the hauling-line will operate to raise the yoke 33 and with it the pin 31 which rocksthe member 28 m a in this figure, thus returning these parts to.

normal position.

Itwill therefore be understood from the foregoing that during the movement of the bucket along the cable-way 8 from filling to dumping position, the bucket is held against dumping even should the haulingline become slack.

The arrangement shown in Figs. at, 5 and Sis the same as that shown in the preceding figures excepting for the mechanism which rocks the member In this arrangement the member 28 carries a pin 40 adapted, in the normal position of the parts, to abut against/the forward'cdges of the carriage (Fig. 4-), the, cable 26 connecting with collars llrotatableonthe pin FL-and the cable 22 connecting with i the member 28. The pi-n-tOccoiiperateswith a latch-device -12- which is preferably formed; ofv a. forked member43, pivoted ;atll- -on a block supported, at pulleys ti on. the cable and anchoredbya cabled? toa bloc zk4 8 sta; tionary onthe cable-way, 8, th'e pur1: ose of this cable connection being to permit. the block-45 and latch-43, to; give upwardly to a slight-degree when struck, by the pin i-O as-hereafter described.

In

the normal position of the member 28 it rests against a pin 53 which extends at its ends carrying washers beyond theplates 10 and 11, into registering arc-shaped slots 55 in the side plates one only of these slots being shown, this pin extending clear through the carriage and being so disposer, that it may be bodily lifted in the register: ingslots and in this movement, by engaging the projection swinging the member 28 in clockwise direction in Fig. 7. The opposite ends of the pin cooperate with levers 56 which are pivoted at 57 to extend at opposite sides of the carriage and engage at their lower ends beneath the ends of the pin 53, these levers preferably being of bent form as illustrated and connected together at their left-hand ends in Fig. 7, which are preferably spaced apart by a cross-bar 58. The levers 58 cooperate with a lever-trippingdevice 59 secured to the cable-way8 at substantially thepoint at which dumping is to be elfected, this device presenting an inclined camming surface 6O against which the pin 58 moves and in which movement the levers 56 are rocked in an anti-clockwise di} rection in Fig. 7 to force thepin 53 'upwardlyin the slots and rotate the mem b er-28. The camming surface prefe erably providedas the under-surface a bar 61 pivotally connected at 62 with a. block 63 secured to the cable-way,8 the free end of this lever being connected with a cable tiit de aending "from the block 63. The lever should be heavy enough to cause the member 28. to, be rotated in a clockwise direction in Fig. 7 against the resistance of the weight tendingto prevent such rotation, the pro vision of the surface 60,. as a part of aswinging lever being for .thepurpose of providing a y ld ng ann n were; e, P'r Y i shock.

Theinormal loadcarnyina...nosition of the rei'n.

ment of the pin 58 with the lever 61rocks the member 28 to a position in'which the cable 26 extends forward of the pivot of the member 28,, whereupon the bucket 15 drops by gravity to dumping position. Upon again drawing the hauling-line taut, the connection of the branch 22 with the member 28 returns the latter to normal position (Fig. 7) and likewise returns the pin 53 and levers 56 to the position shown in this figure.

It will be understood from the foregoing description of the structures illustrated that in each of them provision is made for preventing the bucket from swinging to dump 'ing position should the hauling-line become slackened before the bucket reaches the point of dumping, and that in the operation of drawing the hauling-line taut after the dumping operation has been efi'ected, the means which hold the bucket in loadcarrying position against accidental dumpingthrough the slackening of the haulinglinc, are returned automatically to normal operating position.

lVhile I have illustrated and described certain forms in which my invention may be embodied, I do not wish to be understood as intending to limit my invention thereto,

as altered without departing tromthe spirit of my invention, it being'my intention to claim my invention as fully and completely as the prior state of the art will permit.
