TRANSFER-HOOK.
SPECIFICATION forming part of Letters Patent No. 532,321, dated January 8, 1895.
' Application filed May 10, 1894- Serial No. 510309- (No mod L) To all whom it nay concern.-
Be it known that I, PHILETUS W. GATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi nois, have invented certain new and useful Improvemen'tsin Transfer-Hooks; and I do hereby 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.
My invention relates to improvements in a transfer hook adapted for use in connection with cranes, derricks and the like arranged relatively to oneanother, and right and left of the transfer hook in different parts of a machine shop or other place; and it consists in so constructing such a transfer hook that the'load to be transferred can be hung upon its lower portion, and the .respective crane hooks can enter an idle engagement device of the transfer hook either on the right or left side of the upper portion of said transfer hook, Without being interfered with by the crane hook which is in action or by'the lower part of the transfer hook and when such engagement of either of the crane hooks with an engagement device is fully effected the upper portion of the transfer hook will have automatically adjusted itself so as to have the suspended load or weight come on the sustaining points of the transfer hook which are in the same vertical line and, while this is so the idle transfer hook engagement device will be moved laterally or to one side of said line and thus placed in condition for receiving a crane hook which at a certain stage comes into play for receiving the load being transferred; and this operation takes place whether a right hand or a left hand engagement book be brought into action for taking the transferred load; and during the transfer from one craneho'ok to another any interference of the load-carrying crane hook is avoided-that is, a crane lifting hook which may be in use at a given time does not interfere with a' crane hook which is to take hold of the transfer hook on which the load is suspended.
The invention also consists in the combination of the peculiar transfer hook with right and left cranes adapted for working with the engagement devices of the upper viwhich the upper portion of the transfer hook adjusts itself so as to throw anidle engaging device in position for receiving. the heck of the crane which is to receive the load being transferred, such latter crane hook and ad juncts also being shown in saidview. Fig.
2. is a side elevation of the improved transfer hook'and other parts as shown in Fig. l but the idle crane hookand an engagement device of the transfer'hook are shown in engaging relation withone another, and ready to transfer the load from the first mentioned crane hook. Fig. 3. shows the parts as. they appear after the transfer has been fully effec'ted. Fig. 4. represents a top. plan view of the 'two cranes in their relative positions. Fig. 5. is a vertical transverse section of the improved transfer hook. Fig.6. is a broken transverse section showing a shouldered bolt, instead of a bolt with a sleeve on it. Fig. 7. is a side' elevation, illustrating my invention of a transfer hook with its engaging portion constructed of a single plate, and with oblong engagement passages through said plate for the crane hooks respectively to enter during the transferring operation. Fig. 8. is a front edge View of the construction shown in Fig. 7, and Fig. 9. is a modification of the plate shown in Figs. 7 and 8. I
The transfer hook consists of a hooking portion B and an upper engagement portion A pivotally connected by a pivot bolt 6 which serves with a nut on its end as a clamping means. The preferable manner of constructing the engagement portion is, to employ two triangular shaped flat plates, as a, a, rounded at their corners, and so spaced that sufficient room is allowed between them for the entrance of crane hooks, said plates being sepa. rated and held apart by means of shouldered screw bolts, on the ends of which nuts are applied, said bolts and nuts also serving for clamping the plates together. Before inserting the pivot bolt b the flattened, enlarged upper end of the perforated hooking portion B is inserted between cornered portions of the two plates a,a.; and when the perforation in the portion B coincides with both holes in the plates, the pivot bolt b is passed through these holes as well as through the perforation of the hook portion B, and the whole clamped together by turning up the nut on the end of the bolt. The screw bolts 1), b which are applied near the other two corners of the plates a, a form right and left engagement portions for right and left crane hooks C, D. In constructing these engagement devices, the shoulders for keeping the plates apart may be formed either by means of sleeves, as I), applied on the bolts so as to lie between the plates, the bolts being passed through holes in the plates and through the sleeves, and the whole clamped together by turning up the nuts on one of the ends of the respective bolts; or the shoulders may be formed directly on the bolts 1) b the two constructions just described, being as illustrated in Figs. 5 and 6.
The transfer hook might be made of a single plate, as a said plate having crane hook engagement passages 19 11 through it; or headed crane hook-engagement studs as b answering the purpose of the bolts 12, 13 may project from the face of the plate at the proper corners. When a single plate is employed the upper end a of the hooking portion 13 is bifurcated so as to allow a corner of the plate to be inserted between the jaws thus formed and the bolt 12 is passed through the plate and the jaws of the end a so as to connect the hooking portion 13 to the engagement portion, and allow a pivotal movement of the same for a like purpose, same as when the portion A is made of two plates, as a, a, in the manner shown in the other views of the drawings.
It will be observed that the transfer hook is so formed and constructed of two pivotally connected parts; and with its two crane hook engagement devices or bolts b, 11 and pivot bolt b so located, relatively, that said bolt b and one or the other of the crane hook engagement devices, 1), b will always lie in a vertical line with each other when the load is suspended on the hooking portionB; and,
at the same time, the idle crane hook engage ment device will be thrown to one side of the vertical line, and thereby brought in position for being conveniently engaged by another crane hook at the proper time for transferring the load; and this engagement will not be interfered with by the crane hook then bearing the load, nor by the load; and at the same time the lift of the load will be directly in line with the yoke carrying the hoisting pul ley, which latter result is important and desirable. The same operation takes place whether a right hand or a left hand crane hook is bearing the load. The article or load to be carried, is suspended by chains or otherwise from the hooking portion B. Each of the cranes O and D is provided with a lifting hook O and D respectively, and each of said hooks has a connection by means of a swivelf with the lower portion of the yoke j,
which yoke is suspended by having its ends, respectively, journaled on the ends f of the axle of the pulley wheel H. The pulley wheel H is supported by rope h passed around it, and is suspended from the top of the crane. The cranes are provided with the usual windlasses and pulleys for operating the lifting ropes.
In Fig. 1. the load is shown suspended from the chains, and in Fig. 2. it is shown in the act of being transferred from the right to the left crane hook. V
In Fig. 2. the crane hook C has been placed under the idle crane hook engagement device or bolt 5 and thus, when the suspending rope of the hook is sufficiently drawn upon, the weight will be transferred from the hook D to the hook O; and the right hand crane hook now being released from the bolt b byhand or otherwise, the load will be transferred to 1 and carried by the left hand crane as illustrated in Fig. 3. of the drawings.
When the transfer is about to be made, if the hooks C and D are not in the proper position for engaging the transfer hook, they are respectively turned on their swivel connections until they are caused to assume the position shown in the drawings Figs. 1 and 2.
By my invention the transferring of very heavy loads from one crane to another, can be very readily and easily accomplished, and without any interference of one crane hook with another during-the transferring operation; also without any danger of loss from the falling of the load in the act of transfer.
Preference is given to the triangular shape of the transfer hook, with triangularly arranged bolts, as this form offers the least obstruction to the engagement of the crane books with the engagement devices of the transfer hook when the weight is suspended upon the transfer hook, but, of course, the shape may be varied somewhat without departing from my invention.
The transfer hook shown in Figs. 7, 8 and 9 is useful for light loads,but for heavy'loads the construction in the other views of the drawings, is the best on account of its strength.
What I claim as my invention is-= 1. A transfer hook comprising two members or portions ;to wit: a lower hooking portion B for connecting with the load to be transferred, and an upper crane hooking portion A having rightand left crane hook engagement devices, one of which always stands lateral to a vertical line passing through the one in use when the load is suspended on the transfer hook, substantially as described.
2. A transfer hook, comprising two members or portions ;-to wit: a lower hooking portion B for connecting with the load to be transferred, an upper crane hook engagement portion A having right and left crane hook ention A of triangular form and having right gaging devices, and a pivotal connection beand left crane hook engaging devices, and between the portions A and B of the transfer ing pivotally connected to the hooking porhook; the'construction being such, that the tion B, substantially as described. 25 5 portion Atilts either to the right orleft, and 5.
