To all whom t may concern.'

Be it'lrnown that we, HENRY A.. CARPEN- 'rnn and ARTHUR 1V. VARNER, citizens of the Unitedl States, residing at Sewickle-y, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful lmprovements in Telescoping-Chute Structures, of which the following is a specifica tion.

rlhis invention relates to improvements in telescoping chute structures particularly adapted for use in connection with the charging and discharging apparatus for gas retorts, the structures being adapted to form a passageway for the coal which is to be charged to the vretorts.

Charging and discharging apparatus shown in United States Patents .#1,171,398 of February 8, 1916, and #1,171,111 of February 15, 1916, employ a hopper containing coal to be charged, a horizontally movable charger, and a telescopic conduit for delivering a charge of coal to the charger at suitable time intervals. The first patent mentioned also shows means for effectively preventing the escape of dust dur-` ing the passage of the fine coal from the supplyl to the charger.

In the telescopic chute construction shown.

in Patent #1,171,398 above referred to, the inner section of the chute is iiXedly positioned as to height and the remaining sections movable' relatively thereto in a vertical direction while retaining the joints between the sections and frame substantially dust proof.

In operation of structures of this character it has been found desirable to provide means for permitting an adjustment of the inner section supporting means under normal operating conditions as well as a vertical movement of said'means under abnormal conditions, and the present invention has among its objects means for accomplishing these ends while maintaining the advantages present in the patented structure mentioned. 1n the construction shown herein we provide means for supporting the chute with its opposite ends independently supported under normal conditions and with a common support under abnormal conditions.

In the accompanying drawings, in which similar reference characters indicate similar parts in each of the views,

Figure 1 is a vertical cross-sectional view of a telescopic conduit'and its supporting means constructed in accordance with the present invention, the parts being shown in telescoped position; v

Fig; 2 is a horizontal sectional View taken on the line 2-2 of Fig. 1; y j

Fig. 3 is a side elevation .of the telescope structure shown as secured to a beam carried by a charging machine; and

Fig. l is a detail sectional view showing the manner in which the clust-proof joint is formed when-sections are extended.

In the accompanying drawings, 10 designates ajplural-ity of sections adapted to telescope, these sections being of suitable configuration 4in horizontal section, this contiguration in the use heretofore referred to being preferably rectangular. These sections are generally of similar form butv of different area on such horizontal section, having their upper ends bent outwardly to form flanges 11, these flanges being of a lateral width greater than the distance between adjacent sections. Each flange 11 is also provided with a member 12 which is of a width greater than the width of the flange and preferably projects both inwardly and outwardly beyond the flange as shown in Fig. 1,l these members being positioned on the top face of the iiange.

Externally of the bottom of each section is provided a strip member 13, this member extending into the space between two sections, and forming both a stop member to limit the extending movements of the next outer section by contact therewith of the member 12 of said next section, these two members alsoV acting to form the joint when the relative movements of the twos'ections place them in extended relationship. When the sections are in telescoped position, the

members 12 contact with the end faces of theliang'es 11 and thus provide the closed Y relative joint between such sections.

However, the inner section 102L and the outer section 10b dilfer somewhat from the general section structure, the flange 11 being omitted with respect to the section 10a and the strip member 13 omitted in connection with section 10b. y

The section 10a, instead of being supported by the remaining sections, is secured to the downwardly projecting portion of a frame 14 which loosely surrounds a stationary conduit 15 projecting downwardly from the. hopper (not shown). The strips 1 2a for the first` movable inner section serve the functions of the strip 12 for the' said section by contact with the horizontal portion of the member 14.

The supporting members 14 are carried by a' plurality of threaded rods or bolts 16, said rods or bolts being secured to the member 14 and adapted to extend upwardly through openings in an outwardly flanged portion 17 of the stationary frame, said rods or bolts being freely movable through said opening and carrying above the flanged portion 17 suitable supporting devices such as nuts 18 which act in the nature of seats. The outer section 10b is secured to angle bars 19, these bars being secured to channels 2O carried by girder 21 of the charging machine, said girder being adapted to travel vertically by the action of the hoisting mechanism of the machine, represented in Fig. 3 by the threaded member 22, the rotation of the latter acting to move the girder 21 in a vertical direction. Since the girder and the charger are relatively positioned to have their vertical movements in correspondence, it will be understoodthat any vertical movement of the charger will provide a corresponding movement to the channels 20 and to the outer section 10b and retain the lower end of the chute in permanent position with respect to the charger, but movable with respect to the hopper. The lower end of the outer section is preferably contracted inwardly below the lower ends of the remaining sections 10, thus forming a passagewayv through the inner member 10*l leading toward the charger (not shown). Said contracted lower end is supported by a suitable casing 23 secured to a framework member 23a of the charger. v

As will be seen in Fig. 1, in which the sections are shown as telescoped, all of the intermediate sections are supported by the outer section 10b by reason of the superposed contact of the lianges 11 and members 12, the contact thusformed causing the member 12a to contact with the member 14. This is the positions of the parts whenV the charger is in the zone of safety for the upper row of retorts. Should the operator, in moving the hoisting mechanism, cause the charger to move upwardly beyond a predetermined point, the contact engagement of the pack would simply cause the member 14 to be raised a small distance and thus place'the weight of the inner section and the member 14 on the pack instead of on the nuts 18, the rods or bolts 16 passing upwardly during such movement. Obviously, a downward movement of the charger permits the pack to move downwardly, and when contact is made between the nuts 18 and the liange 17, the weight of the inner section and of the member 14 will be transferred from the pack to the ange 17. If the downward movement of the charger is suliicient to bring it within the next zone of safety, the travel of the girder 21 will have been sufficient to cause the pack (with the exception of the section 10a) to move downwardly a distance which will place the member 12 in contact with the strip member' 13 of the section 10a', this being` the position shown in Fig..4 of the drawings, and in which the joint between the member 10a and the next outer member is closed between the member 12a and the strip member 13 of section 10, Similarly, a further downward movement the succeeding Zone of safety causes the next inner section to contact with the strip 13 of the section previously extended, thus placing the weight ofthe previously extended section on the flanged portion 17 instead of the charger member 19, this divided support being the normal condition of the conduit and changed only when the upward movement has reached the point where the nuts 18 are carried ont of contact with the flanged portion 17 whereupon the entire support is placed on the an- I gle members 19. As this latter takes place only in connection with the upper row of retorts it may be considered somewhat as' an .abnormal condition.

Obviously, this movement of the member -14 under abnormal condition would'be relative to the member 15 and to permit of a ready movement of the parts without deof the charger tostroying the dust-retaining joint structure Y we preferably employ a felt packing 24 interposed between the member 14 and a plate 25 secured in spaced relation thereto, the felt packing being preferably held in contact with the member 15 by means of springs or other suitable devices 26. rangement provides fora wipe joint structure, the movements of the member 14 are only under suchv abnormal conditions and relatively small, so that the general objection to wipe joints in'connection with devices of this type becomes immaterial.

As will be readily understood, by arranging the rods or bolts 16 as threaded mem- While this arbers, the points of contact of members 12 with members 13 can be adjusted, such adjustment providing the proper location for the inner section 10, and the remaining sections providing their contacts at the proper points in connection with succeeding horizontal rows or' retorts, it being understood that the length of travel of each section between a point where its member 12 contacts with the superposed flange 11 of the adjacent section and the point where it contacts with the member 18 of that section corresponds to the distance between the centers of adjacent retorts.
