CONVEYER AND SHIELD USED IN CONNECTION WITH CRUCIBLE S MELTlNG-FURNACESi SPECIFICATION forming part of Letters Patent No. 727,416, dated May 5, 1903.
Application filed August 4, 1 902. Serial No. 118,248. (No model.) i
To all whom, it may concern:
Be it known that], PATRIOKJ. MCDONALD, acitizen oftheUnitedStates,residingat Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Oonveyers and Shields Used in Connection with Crucible Smelting- Furnaces, of which improvement the following is a specification.
This invention relates to certain new and useful improvements in conveyers used in connection with crucible smelting-furnaces, and has for its object a device of this character wherein the operator may travel above the crucible in order that he may be protected from the intense heat arising therefrom.
A further object of the invention is a device of this character which shall embrace novel means whereby the operator may at all times have control of the crucible and may raise and lower the same in order to convey the crucible from the furnace to the soaking-pit, where he conveys it to the desired location.
The invention has for its still further object a device of simple and economical construction, efficient in use, and comparatively inexpensive to manufacture.
With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully'described, and specifically pointed out in the claims.
In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a side elevation of the invention. Fig. 1 is a like view of the brake. Fig. 2 is a top plan view. Fig. 3 is a perspective view of the carriage. Fig. at is a perspective View of the body of the carriage. Fig. 5 is a side elevation of the traveling crane. Fig. 6 is an end elevation thereof. Fig. '7 is a modification of the means for securing the body of the carriage to the runhing-gear of the same.
derstood, engaging on the track 1. end of the frame depend arms 7, secured at The track 1 is suspended by means of the standards or hangers 2, secured to the ceiling 3 of the plant.
The carriage 4 consists of grooved wheels 5, revolubly mounted upon the frame 6, this frame being of a rectangular form, as shown, the grooved wheels, as will of course be un- At each lower end of the arm 12, as at 14:. The free ends of the auxiliary track are supported by means of braces 15, which have offset ends 16 secured to the arms 7 and like ends 17 secured to the free ends of the track 11. The
body 10 has its bottom formed with a longitudinal passage-way 18 and is preferably formed with its one end partially open, as shown at 19. Mounted upon this auxiliary track 11 is a traveling crane 20, which preferably consists of a bar 21, carrying transverse arms22 at its end, on which are revolubly mounted the rollers 23, which engage on the auxiliary track 11. The hook 24 is swiveled onto the frame 21 of the crane, as shown at 25, in order that the hook may have a free movement in a rotary horizontal plane. This hook, as will be understood, is adapted to sustain a block and tackle, (not shown,) the cable of which is designed to pass through the passage-way 18 of the body of the car riage and maybe connected to ajcrucible, whereby the latter may be conveniently raised or lowered by means of a block and pulley, all of which is well known in the art, in order that the crucible may be conveyed from one point to another, as may be found necessary.
In lieu of the arms '7 for supporting the body of the carriage I may employ an arm 26, perforated, as at 2'7, and received on the axle forming the bearing for the rollers for the grooved wheels 5, the lower end of the arm 26 being riveted or bolted onto the body of the carriage, as shown at 28.
In order to hold the traveling carriage in any predetermined position and secure the same against movement, I provide a novel form of brake mechanism, which consists of a plate 29, riveted or bolted onto the frame- 6, as shown at 30, and carrying lugs 31, through which operates the spring-pressed rod 32, carrying the brake-shoe 33 at its lower end, this brake-shoe being adapted to be held normally in engagement with the track 1, thereby preventing 'any movement of the traveling carriage. The spring 34 encircles the rod 32, being engaged by a pin 35 and by the upper of the lugs 31. In order to op-- erate the brake-shoe from out of engagement with the track, and thereby permit the carriage being moved, I secure to the frame 6, as at 36, the standard 37, pivotally receiving the lever 38 at its upper end, this lever being pivoted to the rod 32 and carrying an opcrating-cord 39, which enables the lever to be conveniently pulled in a downward direction, thereby operating the rod carrying the brakeshoe in an upward direction.
In operation the operator stands within the body of the carriage, at which point, as will be noted, he will be entirely protected from the heat,which is well known to emanate from the crucible, and he is in such position that he may conveniently raise or lower the crgcible,as may be found necessary, in order to convey the same to the desired location; but at all times he is out of direct contact with the heat from the crucible.
- While I have shown the most practical embodiment of my invention, still it will be obvious that slight changes and alterations may be made in the general details of construction and combination of parts Without depart ing from the spirit of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a device of the type set'forth, the combination with the track, of a traveling carriage mounted on said track and carrying a body having a passage-way therein adapted to receive the operator,an auxiliary track carried by the traveling carriage, a crane on said track, said crane operating in a plane transverse to that in which the carriage operates, a brake mechanism carried by the traveling carriage and adapted for engagement with said track, and means whereby said brake mechanism may be actuated by the operator, substantially as described.
2. A device of the type set forth comprising in combination with the track, a frame carrying grooved rollers adapted for engagement with said track, an auxiliary track supported by said frame, and extending in a direction transverse to that of the first-named track, the ends of said track extending beyond the said frame and being connected thereto, a body having a passage-Way formed therein and receiving the operator, said body being connected to the said frame, a traveling crane mounted on the auxiliary track and adapted to receive the cable passing through said passage-way of the body and connected to the crucible, and a brake mechanism adapted for engagement with the first-named track carried by the said frame, substantially as described.
In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
