CRANE AN APPCU R-TENANCES.

SPECIFICATION forming part of Letters Patent No. 744,464, dated November 1'7, 1903.

Application filed April 5, 1900.

To all whom it may concern:

Be'it known that we, ARTHUR A. DE BoN E-i VILLE, a resident of the borough of Manhattan, in the county ofNew York, and AU GUST JOHNSTON, a resident of the borough of Bronx,in the countyfof Westchester and State 1 I S R and the rock-shafts R, which swing in of New York, citizens of the United States, have invented certain new and useful Im-.

provements in Cranes and Appurtenances, of

which the following is a specification.

This invention relates to cranesand appurtenances by means of WhiGll'iSIOllGYS can be transferred. to and from different lines of .tram-rail or to and from different cranes.

To these ends our invention consists of the novel combination of parts illustrated in the accompanying drawings, described in the specification, and pointed out in the claims. I

Figure 1 represents a plan view of our de-' vice with appurtenances. Fig; 2 shows a fragmentary vertical section on the lines x 00 and z z of Fig. 1. Fig. 3 is an end view of the device, partly in section. Fig. 4 represents a section on the line 1 y of Fig. 1. Figs. 5 and 6 show, respectively, a plan and an e1e-" vation of a portion of the frame of the crane and a locking-hammer with appurtenances.

. Fig. 7 is an elevation of the clutch-bracket.

' shown with a trolley Y and consists of .the

girder A, secured to the truck-frames B, in which are formed the journal-boxes Z) for the axles D, carrying the wheels-E. Lockinghammers O operate with the hand-chain I and the leversI-I and I, secured to the shaft H, which latter oscillates in the journalbrackets H 1 Clutch-brackets F engage the'locking-hammers O and are secured to the runway-gird, ers T. Stop-levers J straddle the girder A and turn on pins b, supported in journal box brackets b cast with one or both of the frames B. On each line of tram-rail which is.

Serial N6. 11,768. (No model.)

. crane can be raised by the-chains L N and levers M N, secured to the shaft 0, which turnsin the journal-boxbrackets P P.

The stop-levers J are actuated by the chains the. journal-box brackets R.

The truck-frames B, which may be of any suitable form, are provided with suitable flanges'b to secure them to the main cranegirder A.

The frames B are shown to consist, essentially, of the inclined members 12 and horizontal members 19 and at their junction jourrial-bearings b are formed for the truck-wheel axles D. In the horizontal members I) are cast pockets (see Figs. 5 and 6) b for housing the locking-hammers 0. Each of the said hammers is guided through the extended throat b and between the vertical walls 'of the pockets. Straps b are bolted to the pockets b to form the front guides.

The locking-hammers C consist each of a main portion 0, square or rectangular in cross-section on a plane at right angles to its longitudinal axis, with tapering ends 0 and a cylindrical stem 0 leading upwardly and carrying a pin 0 A spring a generally surrounds the stem and rests on the square or rectangular portion and butts againstfthe roof of the pocket. Levers H, having forked ends fwit'h oblong openings, are connected to the stems c by means of the pins 0 the said le-- vers H being carried on the longitudinal shaft H, which swings in the'journal-boxes H cast with orbolted to the frames B B.

The lever I issec'ured to the shaft H, and by means of a hand chain I both lockinghammers can be raised simultaneously, there by releasing them from the clutch-brackets.

To the runway-girders T are secured special clutch-bracketsF, which are shown in detail in Figs. 7 and 8. They are each formed with inclined top surfaces f extending to the central portion of the same, a rear wall connecting the said surfaces. The top s'urfacesf connect with the inclined walls f and form a cavity F, which constitutes a stop for the locking-hammer. The lower portion f! ofthis cavity inclines toward the. front face of the bracket, so that dust or any foreign matter can be easily expelled.

The lower portions of the clutch-brackets are straight horizontal flanges f Vertical wallsf' connect the upper an d lower portions, and through the said vertical walls the brackets are secured to the runway-girders T. The cavities F in the brackets F are shaped to allow the hammers C, which are similarly shaped, to easily lock into the same and to automatically lock the cranes opposite the tram-rails when operating therewith.

It will be noticed that by means of the inclined ends of hammers, as shown at c, and the corresponding faces f of the clutch brackets the said hammers can easily be released from the brackets and that the crane automatically centers itself in proper position opposite the tram-rails.

To the main girder A are bolted safetyclamps X, which serve the double purpose of preventing the crane, with its load, from falling in case the frames B or anything above them should break and also prevents the crane rising or creeping on the tracks by reason of the lower flanges f of the said brackets constituting stops to the said clamps. .l-Eetween the clutch-brackets angle-irons U are bolted to the runway-girders for the same purpose.

The stop-levers J (see Figs. 9, 10, and 11) consist, essentially, of two jawsj, which straddle the girders with which they operate, the upper flanges of said girders being cut away, as shown ataa. The said jaws j are straight on one side, as j and curved on the other, as j and they are tied by the connecting-wall 7 and strengthened by the rihj, to which is cast the foot The levers swing on pins 1), carried on the journal-bracket Z1 extending from the frame B, and it is evident that the said stop-levers can only swing in one direction from the position, as shown in Fig. 10, which in this case is from right to left and when thus swung can be raised clear of the girder A, which would allowa trolley, as Y, to be run from the girder of the crane onto its accompanying tram-rail. Should it be attempted to swing the stop-lever in the opposite direction from the position shown in the drawings, the foot 7' resting on top of the girder, would prevent the same. It will be clearly seen that if it is attempted to run the trolley off of the girder without raising the stop-lever it would be impossible without breaking the lever. This novel feature of our de vice makes it absolutely safe regardingthe danger of one of the trolleys running off of the girders A, A, A or A when the crane is not locked to a run of tram-rail.

The sides j" of the jaws j are curved, as shown, by virtue of which a trolley can be run onto the crane-girder from the tram-rail and impinge 011 the said curved sides of the lever and raise it without resorting to the j, and thereby raise the stop-lever.

hand-ehains. The stop-levers J are secured to the tram-rails A A A, with which the crane is to be coupled, and swing on pins Z1", carried in journal-brackets Q. The said levers are raised and lowered by the chains S and R operating with the rock-shafts R, which swing in the brackets R.

In Figs. 1 and 2 only two tram-rails A A are shown, and the rock-shaft, with its stop-levers J, is shown only over one of them, but it is evident that any number of tram-rails can be employed, the device being specially applicable where many are used. It is also evident that two stop-levers J could be carried on the crane-girder A, as shown in Fig. 14, and in that case the second stop-lever would be used in connection with runs of tram-rail A, which would be placed on the right-hand side of the crane in addition to the tram-rail A, shown on the left-hand side. lVith such a disposition of stop-levers another set of levers, as M N, with their chains and appurtenances, would be added to the crane. Similar cranes can be used at the other ends of the tram-rails A and A and the combination of tram-rails and cranes could be made to suit any situation. The crane could be operated, although not as securely, by employing only one locking-hammer and its corresponding clutch-brackets.

To operate this device, the crane is moved opposite one of the tram-rails, as A, Figs. 1 and 2, the loeking-hammers thereby sliding on the inclined faces f of the clutch-brackets until they are secured in the cavities F, when the girder A of the crane will be exactly opposite the tram-rail A. The next operation, if it is desired to run a trolley from the tram rail A to the crane girder A, consists in raising the stop-lever J by means of the hand-chain R and running the trolley on the crane, it being optional whether the handchain N is employed to raise the lever J or whether the wheels of the trolley are allowed to impinge 011 the curved sides After the trolley is on the girder A of the crane and behind the stop-lever a stop V at the other end prevents the said trolley from running off. The locking-hammers are 110w pulled out of their cavities and the crane removed.

lVhen the crane approaches a train-rail to which it is to be coupled, the locking-hammers are allowed to ride on the clutch-bracket accompanying said tram -rail, and the said hammers will secure themselves in proper position in the cavities of the clutclrbrackets but should it be desired to pass one of the tram-rails and lock the crane to one of the other tram-rails the hammers are kept from looking themselves in the clutch-brackets by being held outof gear with them by their hand-chains. After the crane is locked to its tram-rail the stop-lever J is raised by pulling on the hand-chain N, and the trolley is run onto the tram-rail to which it is coupled in the same manner as when rolling onto the girder of the crane.

It will be noticed that all the stop-levers on the ends of the tram-rails after dropping in place assume position as shown in Fig. 2, and thus prevent any of the trolleys running offof the said rail when the crane is moved away, and the similar positions of the stoplevers J prevent the trolley runnin g off of the tram-rail.
