MATTHIAS W. JELINEIQOF BLACKHAWK, COLORADO.
SAFETY CAG E-CHA|R.
SPltClFlGATION forming part of Letters Patent No. 686,658, dated November 12, 1901- Applioation led April S, 1901.
To all whom it may concern:
Be it known that I, MATTHIAS W. JELINEK, a citizen of the United States of America, residing at Blackhawk, in the county of Gilpin and State of Colorado, have invented certain new and useful Improvements in Safety Cage- Chairs; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iigures of reference marked thereon, which form a part of this specification. Y
My invention relates to improvements in safety cage-chairs for mining-shafts, and may be considered an improvement on the construction set forth in United States Letters Patent No. 667,780, dated February 12, 1901; and to these ends my present invention consists of the features, arrangements, and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.
In the drawings, Figure 1 is a vertical sec-a tion taken through a cage equipped with my improved chair-dogs. Fig. 2 is a top view of the construction, partly shown in section, the rail being omitted for convenience of illustration. Fig. 3 is an elevation of the cage, taken at right angles to Fig. 1. Fig. 4. is a A vertical section taken through the cage, illustrating the means for simultaneously operating the two sets of chair-dogs. Fig. 5 is a perspective view in detail of one of the chairdogs.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate a cage, to whose bottom 6 on the under surface are secured two parallel pieces of channel-iron 7, one being located on each side. At each end of the cage, or the sides adjacent the drifts or tunnels, are located two chair-dogs 8.v Each of these dogs is mounted on a short shaft 9, supported by the iianges 7a of theV channel-iron members. Each pair of dogs adjacent the same side of the cage is connected with a central rockshaft 10 by an arm 12 and connecting-rods 13. The arm 12 is fast on the shaft 10, which is operated by a lever 14, located at one side of Serial No. 54,194. (No model.)
the cage. Each dog is provided with a depending lug 8, with which the outer extremity of the rod 13 is connected. The rear part of the dog, or that shown at the left in Fig. 8, is provided with an opening 8, through which the shaft 9 passes. On each side of the body of thc dog is located a lug Sd, adapted to engage the bottom of the cage and lock the dog against further movement when in the cagesupporting position, as shown in Figs. 1 and 2. The forward extremity 8g of the dog occupies a higher plane than its rear part, and a shoulder 8h is formed on the dog, adapted to engage the bottom of the cage and coperate with the lugs 8d in locking the dog against further movement. The bottom of the cage is slotted between the lugs 8d to allow the part 8g of the dog to pass through. The part 8g of each dog forms a continuation of the rail 15 on the bottom of the cage and is adapted to engage the timbers 16 at each station or level. It is evident, however, that the dogs may be located out of line with the rails, if desired. They may also be used to equal advantage on cages not provided with rails.
If it is desired to stop the cage when descending, it is only necessary to throw the dogs outwardly to the position shown in Figs. 1 and 2 and they will catch on the timbers 16 at the first level below. After stopping, in order to start, it is necessary rst to raise the cage sufficiently to allow the dogs 8 to swing down to a vertical position, as shown by dotted lines at the left of Fig. 1. The cage may then move downwardly without obstruction until it is desired to stop again. If it becomes necessary to land the cage when ascending, the cage must be allowed to pass above the landing in its upward movement in order to give the dogs an opportunity to swing outwardly. As soon as this is done the cage is allowed to descend until the dogs engage the timbers 16 or other support.
Having thus described my invention, what I claim is-m 1. The combination of a cage, whose bot= tom is provided on each side with a piece of channel-iron, dogs movably mounted on the channel-iron iianges and arranged to project outwardly to engage a support at the stations lor levels, the channel-iron members and the bottom of the cage being slotted to allow the ICO upper portion of each dog to pass through whereby the dogs when the cage is landed, rest on a supporting-surface.
2. The combination with a cage, of chairdogs movably mounted thereon, the bottom of the cage being slotted at the ends to allow the upper part of the dogs to pass through, the arrangement being such that the dogs are adapted to support the cage while resting on a supporting-surface, each dog having a lug on each side adapted to engage the bottom of the cage on each side of the slot, whereby the dog is looked against further upward move-
