CHARLES A. DIXON, OF NEWARK, NEW JERSEY.

HOISTING APPARATUS.

Specification of Letters Patent.

Patented May 1 1, 1909.

Application filed January 20, 1809. Serial No. 78,223.

To all whom it may concem:

Be it known that 1, CHARLES A. DIXON, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ersey, have invent-ed certain new and useful Lu movements in Hoisting Apparatus; and I do ereby declare the following to be afull, clear, and exact dcscri tion of the invention, such as will enable t ers skilled in the art to which it appertsins to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to adevice adopted 1' or hoist-in and for automatically retaining the hoisted element so as to relieve the hoisting moons of its weight, and to also revent the return or descent of the hoisting e ement.

The invention is ap lica-ble to a number of uses, but is portion all designed for use in conjunction with dwellings where the delivery of merchandise is made, particularly groceries and so forth, which deliveries are made sometimes in the early morning before the occu ants are about, and the merchandise can lie hoisted to an upper window and left there without any chance of its being removed exce tbvthe occupants. Thisa. ps- I ratus will t ere ore overcome and avoi the thefts that occur in localities where two family or three family houses are situated, and Where material is left on a. door-step or similar situation easy of access, and therefore easily stolen.

The device is illustrated in the accompanyin in whichigure 1 '18 a view of the apparatus secured to the second story of a structure, and with a receptacle about to he hoisted. Fig. 2 is a side view of the hoisting and retailing devices. Fig. 3 is a. front view of Fig. 2. Figs. 4 and 5 are a. side and an end view, res ectivel-y, of a..mo(lificd form which also cm odline sft'erthe hoisted element is in its remined position.

The-device is adapted to be attached to any convenient part of a structure and is refer-ably disposed alongside the window of l is so ended thereon. he upper' fioors ofli'ouscs contaii iing-niore than one family.

ably has the {air-n1 *1-3 to strengthen it.

In the referred f outer edge of the pn end of the line 16 depends, it passes substan- 5 wardly from the bracket 11, and between these cars 14, which act as a. bracket therefor,

is arranged the pulley over which Jasses the rope or similar flexible line 16 whic also passes over a pulley 17 which is arranged )etweeu the ears 18 on the base-plate 12, and then extends downwardly as shown in 1 and can be lefttp hang loosely, or preferably is secured to the structure so as not to run free over the pulleys.

Below the bracket 11 is a retaining bracket 1 9 which has the brace 20 for strengthening it, and the bracket 19 is rovicled with an eye or its equivalent, wich eye has the opening 21 therein, which opening is substantially 1per mrndicular with the ey 15 so that when the tially through the center of the eye on the end of the bracket 19.

A catch 22 is secured to the end of the line 16 and it has a. hook 23 or similar means by which it is adapted to support an element 24 to be hoisted. 'The catch 22 is provided with means which are adapted to assupwardly through the eye on the end ofthe retaining bracket 19, but which are prevented automatically from assing downward unless manually manipu' stecl at the top, and the catch therefore suspends the hoisted element in position until releasul. The catch is preferably made with the 25 arranged on opposite. sides of the catch and pivoted to the lugs 26, and havin the noses 27 to come up against the sides 0 the catch to limit the movementof the wings 25. The Wings therefore can cells so downwardly and nearly against the sides of the catch and are thus unable to pass through the e ein the end of the. retaining bracket 19. zVhen they pass through "the eye they are. pressed downward and inward against the springs 28, and as soon as the 1 ends of the. wings are through the openin max an apparatus for releasing the hoisting 5 7 2-1, the springs 28 snap the wings apart am they rest on the top end of the eye, andwhen a. pull on the line 16 is relaxed, the wings set in place as shownin Fig. 2 and it is ini ossible to agarn lower the-catch, fund the evlce This apparatus can "A catch thtut is'dosigned to release the l nc 2. orm' he cm 1 1 project downafter the hoisted element suspends is be used in n, nun-flier of situations, and securely elevates a device device consists of s'bracket-l'l which Without any chance of-its bein ugainjl projects' fromtlreElinsesplate 12 and prefercred unless manipulated froin't e,-top;-'

shown in Figs. 4 and 5. Theeatch in this ally secured to the celeb and nor-null bungform comprises the body portion 29 having the wings 30 operating as in the described structure, and having t e sprin s 31 to force them apart after they are throug 1 the eye of the retaining device, and above the wings I pivot one or both rods 32 which have the semi-circular portions 33 on their ends, which, when fitted together, form a ri as shown in Fig. 4, these being norma 1y ulled together by the s ring 34. The on s of the rods 32 are bent to arm pro 'ectin fingers 35 and noses 36, and thev are iorce inward as in dotted outline in Fig. 4 to cause the semi-cir ular portions 33 to separate, and a ring 37 or any other equivalent, on the end of the line 16, is at once released and can be lowered for another package, and in this way catches can be alternated on the same line, or aseries of catches can be used to successively hoist elements in place and leave them elevated.

I claim is 1.
