I3 Claims.

This invention relates to a device known as an emergency slide for use on inclined guy wires extending to the ground from oil derricks or other These slides are employed to onthe structure who may be in danger from fire or an explosion to escape by riding the slide down the guy wire or cable. As usually constructed these slides must be applied to the cable by passing the cable longitudinally through the slide. Slides of this kind usually include means for exerting a braking force on the wire or cable as the slide descends on it, but such means sometimes jams and the use of these slides sometimes causes injury to the workmen using them. The general object of this invention is to improve the general construction of slides of this kind and to produce a slide of simple construction which can be readily applied to the wire or cable without necessitating sliding the carriage over the end of the cable; also to provide a slide of this kind with simple means for insuring an application of effective braking force on the cable and for enabling the braking ,force to be readily controlled by the rider who is riding the slide.

One of the objects of the invention is to improve the construction of the brake device and to provide a brake device on such a slide which will not jam and which will not injure the cable.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combinations of parts to be described herein- I after, all of. which contribute to produce an efficient guy wire slide.

A preferred embodiment of the invention is described in'the following specification, while the broad scope of the invention is pointed out in the appended claims.

In the drawing: 1

Figure 1 is a side elevation of a slide embodying our invention, certain parts being broken away, and illustrating the same applied on an inclined guy wire or cable indicated as attached to an elevated point on a derrick or similar structure. a v V V Figure 2 is a cross-section taken about on the line 2-2 of Figure 1, passing through the casing of the slide and showing the lever mechanism in elevation and partially broken away.

Figure 3 is a side elevation broken away an shownpartiallyin section, and illustrating the adjacent portion of the cable broken away. This view'illustrates a roller type of brake shoe for engaging the cable. 1 r a Before proceeding to a detailed description of the emergency slide, it should be stated thatin practicing the invention the slide is preferably constructed with means whereby the weight of the rider supported on the slide applies the brake, and means is provided for enabling the force of application of the brake to be regulated.

Another feaure of the invention is that means are provided for latching the brake in a position which will hold the slide fixed on the cable, and this feature is useful infacilitating the rider mounting himself under the slide without danger of its starting before he is ready. The-slide is also preferably constructed so as} to enable it to be applied to the cable orwire by a lateral movement onto the wire.

Referring more particularly to the parts, 1 represents a carriage in the form of a casing which may be formed out of plate metal from a blank the upper portion of which is bent so as to form two side plates 2 and 3 that are parallel with each other and the lower portion of which is bent around to form a channel-shaped bottomseotion for the body with two side walls 4 and 5. In this way a longitudinal opening or slot 6 is formed in the lower portion of the body, enabling it to be applied to a cable, such as the guy wire 7, by a lateral movement.

In the upper portion of the'carriage we provide means for guiding the carriage on the cable. For this purpose we prefer to provide two rollers 8 spaced apart and mounted between the two plates 2 and 3. These rollers are grooved to fit over the upper side of the cable. i

We provide brake means, preferably in the form. of a brake shoe 9 pivotally mounted at 11 on the lower portion of the carriage and, in order to prevent any possibility of this brake jamming on the cable, the pivot pin 11 is so placed that the shoe projects toward the higher end of the cable or wire, for example, toward'the right as illustrated in Figure 1.

Suitable means is provided for supportingthe rider on the slide and for controlling the brake. The rider-supporting means is. preferably supported on the carriage in such a .way that the weight of the ride'rapplies the brake. For this purpose the rider-supporting means preferably includes a brake lever. 10 rigid with the brake 9, and hanger means in the form of a shackle 12 attached at its upper end by a pivoted knuckle 13 to the lower end of the brake lever. The shackle 12 may have theform indicated, the lower end being forged into a largewide stirrup 14 inwhich 2 the rider may sit or through which he may place one leg.

The construction provides means for enabling the rider to shift his weight with relation to the carriage so as to regulate the force of application of the brake. For this purpose we provide the carriage with an outwardly projecting rigid arm 15 on which a hand lever 16 is pivotally mounted, said lever being preferably in the form of a bellcrank lever with a short arm 17 that is connected by suitable means with the arm of the brake lever 10. This means is preferably in the form of a link 18 having adjusting means 19 for enabling its length to be regulated.

The hand lever 16 may be latched in an ex-v treme position such as that in which it is illustrated in full lines in Figure 1. This will hold the brake shoe 9 in a position to put an extremely large bend or kink in the cable between the rollers 8 and will hold the slide against movement down the wire. The lever may be held in this position by a link 20 that is carriedon the lower end of the fixed arm 15 and retained there by a stout bail or handle 21.

The brake shoe 9 may have a facing 9a of material particularly adapted for this purpose,

The guiding means, for example, the rollers 8, are located in the casing so that, when the carriage is supported on the cable, the cable will be 1 located above and out of line with the slot 6. In

this way there is no danger of the carriage becoming accidentally dislocated from the wire. When the brake is in its extreme position, indicated by the lines at 91), the slot 6 is leftvclear to permit the carriage to be slipped over the cable. If desired, instead of employing a brake shoe of the type illustrated in Figure 1, we may provide a roller 22 for thispurpose (see Figure 3). In other respects the construction would be substantially the same as that already described.

In order to facilitate the carrying of the slide it may be provided on its upper edge with a stout bail or handle 23 and, if desired, the side face of the plate} may be provided'with a hand-hold 24.

In practice the slide should be held at the upper end of the guy wire near the eye-bolt 25 that connects it to the side 26 ofa derrick or other structure.

When using-the slide to escape, the workman gets into the supporting means 12 and as soon as he is ready to start the slide he pulls the lever 16 toward him. This will release the link 20, which will drop down to the position in which it is indicated in dotted lines. The rider on the slide then maintains hold on the hand lever 16 but permits itto move toward the derrick slighte ly, which movement reduces the braking force and in this way the rider can permit himself to descend on the wire. If his speed of descent 3 becomes dangerously high, he can check it more or less by pulling the lever 16 over toward the fixed arm 15.

It is understood that the embodiment of thev invention described herein is only one of the many embodiments this invention may take, and

we do not wish to be limited in the practice of the invention, nor in the claims, to the par-- ticular embodiment set forth.
