■ balm, in this hanging, loosened and pulled forward or pushed so that they no longer smoke to be designed in such a way that they wear two adjacent rows of caps and hang on these two rows of caps when they move "- such a kind of stretcher, that they can be crazy together one and the same cap row or two adjacent Kappehreihen be interconnected"

Instead of two, the box-shaped caps can also form three or more G-Ieitbahnen and the S & ^ ea- can stand in the middle or outside in the middle under the caps. If necessary, caps with only one slideway were also used.

The invention check relates further to suitable for the box-shaped caps Ausbilduageh of the head pieces of the S ^ amstütse ^ on suitable couplings ms compound of one another zureihenden, the caps forming Srägerstücke as well as means which allow to move hinged cap compounds rigid, the angle aneinanderstosseader caps au adjust and / or maintain kohlenstosseitig vorzupfändende caps cantilevered or even to keep consuming caps in rape field until they have been transferred bearing main, fltil -feMMfc the kohlenstosseitig connected caps.

In the drawing shows:

Fig. 1 shows a cross-section through an exemplary embodiment of a box-shaped cap according to the invention with two slideways and a stamp that engages in one of the slideways ,

Fig » 2 is a side view of two caps coupled to one another, of the embodiment shown in Fig. 1,

Fig. 3 is a vertical longitudinal section through the coupling,

Fig. 4 shows a cross section of another embodiment of the box-shaped cap and two punches engaging in their slideways with differently designed head pieces,

Fig. 5 is a side view of a further embodiment of a cap coupling,

Fig. 6 a transverse connection through a cap with three sliding taps and a punch to be placed in the middle under the cap and

Fig. 7 shows a longitudinal section through the abutting ends of two caps with means for rigidity or angle adjustment the cap tie *

The caps a are rigid, short Hragerst-Uclce _i which are made of several suitable profiles from a lot of sweat at his ability. They "form on the underside in the longitudinal direction of the caps running, at the bottom open sliding flags h with edge strips c, which form part of the profiles used" or are attached to them in any suitable manner.

The head pieces d of the extendable temples, for example consisting of inner and outer temples in a "known manner," grip into the slideways h -g> f a. The head pieces are conveniently attached to the stamps f in an articulated manner (see Fig. 1 and 2). Also received they are of such a shape that they can be displaced in the sliding taps h and swivel to certain sides or to all sides within certain limits are cash. At right angles to the slideways, the head pieces are of such a width that, when the punch is relaxed, they rest on the strips c place, which then hold the punches hanging in the slideways of the caps. The head pieces are useful in the longitudinal direction such a length that when they are pushed in a row of caps they bridge the gaps between the caps that are coupled to one another. The head pieces can be provided with rollers g, suitable pins, strips or the like, which facilitate sliding on the strips c.

According to Ahb. 2, the head piece d consists of a longer support piece, which at the same time takes over the alignment of the cap support a! can.

In the embodiment according to Fig. 6, the box-shaped cap a has three slide taps b on the underside. The stamp f is here Mi placed in the middle under the cap in the middle track · * Us is by means of an adjustable linkage e with an essentially running device consisting of rollers g 'connected, which is guided in one of the lateral tracks. If the stamp is released, then

it hangs on the Rollvorrichlrung g ¹ and can easily be pulled or pushed along the row of caps who df η. In doing so, it can be swiveled out at will and thus evade other punches that support the row of caps in the middle and be moved past them.

The carrier pieces a forming the caps can be connected to one another in an articulated manner or in a desired manner and for this purpose any suitable coupling agents can be used. A particularly advantageous coupling is shown in FIGS. 2, 3, 5.

According to this, each carrier piece a has a pin h, h 'on both sides at one end and an eyelet i and a hook i'"eyelet and hooks can be rigidly or articulated on the cap. The hook i 'is cranked so that its distance from the eyelet i is greater than the width of the cap. This creates a margin that can be filled by a wedge k. The wedge possesses * a longitudinal slot m, in which the pin h ^f loosely engages. The wedge can have a thin extension in which the longitudinal slot m is closed. The pin h * can have an undercut η on the cap, into which the wedge with the piece closing the slot m can hang when the connection between the caps is loosened. Once the wedge k has been removed, the eyelet i can be loosened from the pin h by knocking ^{back the hook i 1 xmd or sliding one piece of the cap across the other.}

In the pre-seizure, the cap pieces last attached in the direction of the coal face must be load-bearing cantilevers opposite the hanging wall and, if necessary, can form a certain angle with the subsequent cap pieces to adapt to the hanging wall. This is achieved by wedges that were located in the cap coupling for use and between those that butted in the coupling Caps are driven.

In the embodiment according to Fig. 2, a transverse wedge ρ is used for this purpose, which is inserted into opposing slots q. the cap ends is inserted.

For this purpose, the design according to Fig. 5 shows a longitudinal wedge r, d - r in one or more of the slideways b on the push rod]

of the caps a to be connected and is driven in over a semicircular elevation a of an insert t inserted into the end of one cap * The wedge r and insert t can be loosely connected to one another in any way ₉ so that they always stay together.

Be the version according to Fig. 7 are under the ^ cap connection

connected

^{two circular segment pieces ν, ν 1} rotatable with one another are provided in the vertical plane, between which a wedge u can be driven into the corresponding guide section and thereby firmly connected to this, while the segment piece ν loosely engages the underside of the other cap.

Wedge devices of the type shown in Figures 2, 5 and 7 can

can also be used to steal the caps in the

For this purpose, however, one can also use auxiliaries which are inserted like a stamp between the person lying down and the cap to be stolen. But it can also be inclined supports which are supported on the stamps of the adjacent carbon-side caps.

The invention also provides to connect the caps to be stolen by chains, ropes or rods with shoulders, which are in this or that path of the row of caps can be guided. With these aids, the stolen cap is transported to the end of the coal much easier. All or any other construction elements, such as the wedge devices or the mentioned auxiliary
