APPARATUS FORiHANDLING LOQ'SE MATERIAL.

Application filed October 15, 1921. Serial No. 507,857.

To U wlmi/t 'it may conca/fn:

Be it known that I, JOHN S. I-IoUsMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Apparatus for Handling Loose Material, of which the following is a specification.

This invention relates to improvements inv apparatus for handling loose materiahand has for its principal object to produce a new and useful apparatus of the class described and an improved methodof operating` the same.

The invention may best be understood by reference to the accompanying drawings, in

vwhich Figure 1 is a plan view illustratingI a typical installation of my improved apparatus in a mine.

Fig. 2 is a side view of the apparatus shown in Fig. 1.

Fig. 3 is an enlarged side view of the guide.

Fig. 4 is an enlarged cross-section of the guide and jack constituting a portion of the present invention.

One of the common practices in mining operations is to advance the work along a comparatively narrow room, as for instance, when .forming entries in a mine, or when removing material by small .sections or slices vancing the end wall or working face in any one of several well-known methods, such as pick mining or blasting. The loose material from the working face is broken down and deposited in a pile on the floor of the mine adjacent the face, asis shown in Figs. 1 and 9., in which 1 indicates the working face of the room, 2, 2, the side walls thereof, and 3 a pile of loose material resulting from breaking down the working face. I

Among the many methods of removing the loose material heretofore employed is that of employing a draft operated scraper which is reciprocably moved on the mine floor to gather the material and transport it to the mine cars. My improved apparatus is designed to use with scraper devices of the class described, and provides a novel means for anchoring the advance guide for the draft ropes adjacent the working face, together with means affording lateral movement of the advance guide so that the path of movement of the scraper may be shifted Such rooms'. are formed by ad-v `however, that any other suitable form of reciprocating scraper may be utilized as desired.

Vith scrapers of the general class above described, it is necessary to provide a suitable advance guide, such as a sheave or its equivalent, anchored at or near the working face 1, so that the tail rope 6 may be trained over it to draw the scraper rear-- wardly as near as is practicable to the work-r ing face. As heretofore practiced, guides have been attached to a mine jack of the usual type and the jack has been fixed in a lgenerally vertical direction so as to engage l between the roof .and the floor of the mine,

or in some instances, at an incline between the roof and the working face, or the worl-I- f ing face and the ioor. Another method has been to fix a guide directly to the working face by embedding ananohor 'in the` mine wall. `Such devices, however, have proven unsatisfactory for one reason or another. In using mine jacks it is usually difficult to find a suitable place for firmly fixing the jack, particularly when the jack yhas its lower end engaging the floor, in

which case it is necessary to dig out the loose material adjacent the face of the mine to get a firm footing. Furthermore, in all of the methods heretofore employed, it has been necessary to shift the position of the anchoringmeans of the guide several times during the gathering of the pile, in order to allow the scraper to dig at various points across the room.

Referring now to my improved apparatus, I provide a jack 8 comprising an' elongated body portion 9, a telescoping pick portion 10 at one end thereof, and a Screw device 11 adjacent the opposite end thereof. A series of holes 10a, 10il are provided in the pick portion 10, and arranged'to register with a pin 10h on the jack 9 to adjust the length of the jack. The screw device 11 lll) may comprise any suitably operated ineclianism adapted to expand the jack longitu dinally so as to engage the opposite ends 12, 1-2, 'o-t the'-jacli v'Withthey sidev vvalls2, 2. In the embodiment illustrated', this'v screw member comprises a shaft 13 having threaded engagementl with a sleeve 14 abuttingcircular guard 18. A slieave 19 is rotatably mounted Within said gua-rd and is retained in place by a ring,` 2O having threaded engagement with the` sleeve 17, and provide-d with a radially extending arm`21 i'orunscrewing the ring when it is desired to remove the Asheave-19 from the gua-rd 18. Means =toroiling the sheavc' comprises an annular recess 22 formed in the'hub of saidsheave and having an oil pluie` 24 communicatingvthereivithl" rllhe entire guide member 16 is adjustable in any desired position along the body member 9 o'i' the j acl; as already described, and is provided With'suitable* means for 'holding it in position Ysuch as a set screw 25 'carried by the sleeve 17.

The use and `operation of mvvdevice is as follows: Aftery the loose materialhas been dislodged from the Working-'1 tace into a pile'7 the jack S is placed transversely oi' the entry or slice adjacent andsubstan-4 tially parallelavith tliewvorking tace.' The jack "is readilyput into position Yalcove the top ot the pile oit loose material 3, as indicated in Fig. 2, so thatthe ends 12, 12, have a rm foundation in the side ivalls 2, 2. The tail rope .G connected with thescraper is trained over the pulley19 by removing thel ring- 20 and slidingthe' sheave 19 laterally` ironfi-underthe guard' 18 a sufi'icient -disftance to receive the' tail rope.-

The sheave 19 and 'ring 2O arethen replaced to their normal positions shown in F 1g. L1, so that the tailg'fropcfo' Will'be linaintailned'from 'acoi-y dental displacen'ientby thegi'iardV 18. The device is then ready for operation. The scraper is movedrecipi'ocably to gather niaterial in the usual manner. It is desirable, however, to change the path of movement or' the scraper from time to time and this may be accomplished by sliding the` guide member 16 laterally along the j ach 8 to any 'desiredposition.

Although I have shown and described one form in which my invention may be em bodied, it Will be understood that many' other means may be employed `for accom'- plishingthe same results Without' departing Jfrom the spirit and scope ot my invention. My improved apparatus may also 'be advantageously applied to uses other than' that shown and described herein. 1 do not theretore Wish to be understood as limiting my.- seli to the specilic construction'or use illustrated herein excepting` as specifically lim;

ited in the appended claim.'vv

1 claim as my invention: 1n an advance guide for a reciprocably operated scraper1 the combination of a jack adapted to be fixed between lateral abut! ments, comprising a telescoping pick portion at one end thereof anda screw device adjacent the opposite end'thereoi, a sleeve member slidably inoimted on saidjacli, a rope guard on said sleeve, a rope sheave loosely mounted 'coaxially with said sleeve and Within said guard, and' means vfor securingsaidv sleeve member in a plurality of positions along' said jack.

Signed at Chicago,`in the'county of Cook and State of illinois` this thirteenth dayotI October, 1921.
