SAFETY-GUIDE.

Specification of Letters Patent.

Patented Aug. 2a, 1911.

Application led March 6, 1911. Serial No. 512,489.

To all whom it may concern:

Be it known that I, PATRICK SHEEHAN, a citizen of the United States, residing at 316 East Ninetieth street, New York city, New York, have invented a new and useful Improvement in Safety-Guides, of which the following is a specification.

This invention relates to elevator appliances and has for its object the prevention of injury to employees and damage to property incident to the use of hoisting elevators in the erection of buildings.

In erecting a building it is the practice to carry the concrete, plaster and other materials in wheel-barrows, and the wheel-barrows are raised from the basement to the floor desired by a lift or elevator. This elevator is operated from a hoisting engine by signals, and quick action is required in deposit-ing the wheel-barrows on the lift, giving the signal, and proceeding with the hoist. The elevator itself is necessarily compact, and it frequently happens that wheel-barrows are placed on the elevator platform or car so that the handles at the rear, or the wheel in front, projects over the edge of the elevator platform or car so thatwhen the latter is raised the wheel-barrow or elevator or both are wrecked in passing a iioor above, and the workmen are frequently injured as well. Various attempts have been made to overcome this evil and to provide some sat-isfactory means for preventing the over or under positioning of the wheel-barrow. But on account of the fact that the wheel-barrows are rolled onto and off the lift half the time from one side and half the time from the other in the course of erection of the building and the various floors thereof, it i's obvious that no mere stop or wall forming part of the elevator can be used. It is further clear that the temporary character of the whole installation will not permit of any expensive attachments.

It is the purpose of my invention to provide what I term an improved safety guide and which is a device or attachment which will permit the proper positioning of wheelbarrows on an elevator platform or car, which will permit the wheel-barrows to be rolled on or olf in either direction, which will permit the wheel-barrows to be faced in either direction, which is very easy to attach, and which is cheap to construct and durable.

With the foregoing in view, the invention consists in the improved safety guide as hereinafter set forth.

In the drawings, Figure l, illustrates in side elevation the use of a safety guide embodying the principles of my invention; Fig. 2, is a top plan view; Fig. 3, is a side elevation; Fig. t, is a vertical section; Fig. 5, is a bottom plan view; Fig. 6 is a side view of the bar; Fig. 7, is an end view of the same; Fig. 8, illustrates a gib screw which may be employed with my invention.

lIhe invention will include a metal casting or body having a hopper shaped pocket on the upper side and means by which the casting is attached to the floor of the elevator platform.

l denotes broadly the casting as a whole, and 2 denotes the hopper shaped pocket on the upper side thereof. The construction of the pocket may vary somewhat in practice, but in the best constructions will include certain features or characteristics which I will later describe.

The casting has a considerably greater length than its widthwise dimension and the upper surface is inclined downward from the pocket toward either end by a comparatively long gradual incline 3 so that the legs of the wheel-barrows tend to run naturally up the inclines and drop into the pockets, and further so that the workmen hastening across the car from either side will not trip over the safety guide. Also I prefer to roughen the surface of the incline so that it will constitute a foot-hold, and the best form is that illustrated in which a series of inclined teeth 4 pointed upward give the best protection against the foot of the workmen slipping down the incline and vat the same time offer a minimum obstruction to the wheel-barrow legs riding up the incline, or the foot of the 'workman likely to trip thereon.

The bottom of thel casting is ribbed in the interests of strength and lightness. The form of the bottom also coperates with a longitudinal adjustment which I provide,

and by means of which the safety guide is equally adapted for use with wheel-barrows moved onto the lift from either side. Referring to Fig. 1, the outline of an ordinary wheel-,barrow is shown inabout the way it willbeplacedupona'lift From this diagram it will be seen that thertwo legs of the wheel-barrow fall on a line somewhat back of a central-'plane so that vif the wheel-barrow is pushed ontol the elevator from; the opposite sidethe legswill be as much on such l other side. of; the fcentral plane. total difference in. ositionwamountsto per.- haps 8 inches in .ordinary practice. Accordingly I provide a means for adjustingmy safety guide a sufficient.l distance tozaccominodate the vabove two p ositions offa wheelbarrow. In the best constructions embodying the-invention,.there wil-lbe provided a bar 5 of preferably square transverse section and having holes by which itis screwed to the floorrofthe lift.- Thel undersidee of the safety yguide is recessed with a groove. `61 hav` Y ing a. transverse section corresponding` to that ofthe bar; Means will be provided for securing the safetyf guide to the bar` in any positionof longitudinal adjustment. Ordinarily there will be holes 7cored laterally in the casting near eachcendithereof and eX- tending over ythe bar sothat gib screws 8 may be inserted in the coredholes with the hooked-over ends 9 engaging the bar 5.

10. denotes nuts by whichfthe gib screws are tightened.- The.l gib screws may be located inthe holes onzeithen side', ofthe `bar as is most. convenient, and do not preventthe removal of the entire safety guide fromthe elevator platform when desired.I

11 denotes screw holes by which the safety.

guide mayI be vpermanently attachedtov the floor of an eleva-tor platform in case the longitudinal adjustment isnot required.

I have already referred to the pockets 2 which have a widthrsufficient to accommo Thel `casting in the interest-s of strength and lightness. In the approved construction the casting Vwill have a bottom face as particularlyr shown in Fig. 5, with passages 15 grooved therein and recesses 16, and the middle or main portion of the casting,V will have a contour corresponding to the upper surface. There will however be strengthening ribs 17 and 18 in order to have the high degree of rigidityzandstrength which is required in such an appliance.

Inoperation a pair ofzbars 5'. are screwedk upon the. floor of the elevator platform parallel to one another and separated: a distance corresponding `to the separationofthe legs of a wheel-barrow; The castings .l'will then be tightened in place on the bars at one end or the: other-thereof according to the direction that the` wheel-barrows are pushed onto the car. The legs tend to'run upA the incline from either: side -in-an obvious manner when4 the wheel-'barrow' is pushedinto place and furthertend :to drop vnaturally into the pockets 2.V Underr` these circumstances the wheel-barrow is-certa-in tonbe properly positioned and the workmen are lrelieved'of the usual care and anxiety. When the wheelbarrow is to .be removed, itis readily liftedV outof the pockets andlcaube pushed orpulled off the carin either direction.
