1 WILLIAM T. MARTERSTECK, OF SHARON, PENNSYLVANIA.
DEVICE FOR CHARGING AND DRAWING INGOTS AND THE LIKE.
Specification of Letters Patent.
' Patented Sept. 25, 1-906.
Application filed January 6, 1906. Serial No. 294,978.
To all whmn it may concern:
Be it known that I, WILLIAM T. l\/IARTER STECK, a citizen of the United States, residing at Sharon, Pennsylvania, have invented certain new and useful Improvements in Devices for Charging and Drawing Ingots and the Like, of which the following is a specification.
In an application filed January 6, 1906, No. 294,97 9, I have described an apparatus for charging ingots and the like into a heating furnace and withdrawing the ingots therefrom, this device including an improved form of boom, together with a novel con struction of the dogs for engaging the ingots and the details of construction connected with these parts, and as these parts are capable of use with other forms of apparatus I have made them the subject of this independent application.
I have aimed to reduce the parts to their simplest form to make them readily renewable when worn out or distorted with the least possible expense and delay.
In the accompanying drawings, Figure 1 represents, detached from the machine, a plan view of a boom with the lifting-dogs and supporting-head. Fig. 2 is a sideelevation of the same. Figs. 3, 4, and 5 are detail views.
The boom is mounted so as to have pivotal movement from the bearing A on a suitable framework, such as shown in the companion application, and which is capable of movement in front of the furnaces to be charged and capable, further, of movement to and from the furnaces, so as to charge and discharge the same through the medium of the boom and its lifting-dogs.
The boom consists of a tubular casting B, which incloses a rod a, which is given movement back and forth by a suitable screw connection of ordinary construction, as indicated at b, which is driven by a motor 6 through suitable gearing d. The rod extends to the front of the boom and engages a block C, fitted within the open space of the head D, which is joined in a simple and inexpensive manner detachably to the headed end of the extremity of the boom, as shown at e.
The head D is of the shape shown, and at its outer extremities it supports the ingotgripping dogs f, which are held in place by bolts passing through the extremities of the head and the angles of the dogs, so'that nothing is required to remove any one of the dogs and to replace it with another perfect dog but to pull out one of the loose pins shown at g. This adds very much to the efficiency of the construction, as it is well known that these dogs being subjected to intense heat are frequently cracked or otherwise injured and need to be replaced, and with my improved construction this can be done with the greatest ease and with but very little delay. The operating angular extensions of the dogs are made in the form of gear-teeth and project into an opening extending through the pulling-block C, formed to correspond thereto, and thus secure ease of movement without danger of clogging, and the construction requires a simple engagement with the adjacentfaces constituting the walls of the recesses within the pullingblock, and as no permanent connection is necessary the removal of the pivot-pins 9 allows the dogs to be immediately disengaged. The rod a is connected to the pulling-block by a pin or bolt h, which may be readily removed when it is desired to replace the block. The rod has an eye formed at its end fitting a recess in the end of the pullingblock C, and the bolt h passes through the eye and through corresponding openings in the upper and lower walls of the pulling block constitutin the recess. The head D is also subjected to intense heat and requires to be renewed, and for this reason I make this part also detachable and connect it in a very simple manner, as shown, to the end of the boom. It will thus be seen that the parts of my improved device are all of the simplest character, the construction requiring no expensive machining, and all of them are readily replaceable by new parts in case of wear or breakage.
Having thus described my invention, what I claim is i 1. In a device for charging ingots and the like, a boom, a head secured to said boom, dogs pivoted to said head and having angular extensions, a pulling-block connected to pull directly upon the angular extensions of said dogs and adapted to move the same to engage or disengage the ingots, and operating means for the pulling-block, substantially as described.
2. In a device for charging ingots and the like, a boom, a head carried by said boom, dogs pivoted to said head having extensions projecting 'inward toward each other and in a line transverse to the length of the boom, a pulling-block having transversely-arranged openings in which said extensions are seated, and meansfor operating the pulling-block.
3. In a device for charging or drawing in gots, a boom, a head detachably connected therewith, dogs pivoted to said head, and a pulling-block for operating the said dogs with means for actuating the pulling-block, substantially as described.
4. In a device for charging or drawing in gots and the like, a boom, a head detachably secured thereto, dogs detachably secured to said head, a pulling-block detachably connected with the extensions of the dogs, operating means for the pulling-block and a detachable connection between said means and the block, substantially as'described.
5. In a device for charging or drawing ingots and the like, a boom, dogs pivotally supported and having angular extensions in the form of gear-teeth and a pulling-block having corresponding recesses adapted to receive said gear-teeth extensions with means for operating the pulling-block, substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
WV. T. MARTERSTECK.
