ASH-CAN STAIR DEVICE.

Application filed April 11,

To all w/zom it may concern:

Be it known that I, CALLO D. FAHRNEY,

a citizen oi the United States, residing at Number Twenty-six Ellery Street, in the city of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Ash-Can Stair Device, of which the following is a specification.

My invention consists of a simple device and has for its object to enable a person to move filled ash barrels or other heavy ob jects up an ordinary stairs with comparative ease.

Referring to the accompanying drawings, Figure l is a perspective showing the device in position on an ordinary stairs.

Figure 2 is a front or top view showing thedevice in an operative position on the stairs.

Figure 3 is a view intended to show how the device, in the term as here. applied, may be converted into an ordii'iary carrying; hand truck while not employld tor stair ascending purposes.

Figure 4 showsa modified form.

Like letters refer to like parts in the different views.

The device illustrated consists of a handled frameof rigid construction adapted to receive and retain the ash can or other object being transported, supplied with wheels and provided with what I shall term herein pivoted supports, indicated respectively by 4 and! 5 and attached to the axles.

In the adaptation of my invention as here shown the pivoted supports, 4- and 5, are free at one end and extend beyond the limit ol the wheels. With. the device in position on the stair as shovn in W these snppnxs gra ate and will ch thereon on either o both sides the appa atu moved upwardly and forwardly i e operator. In operation the handles are seized and with the wheels hearing against the next step above the operator liit'ls on the handle to his right raising: the load on that side while it is supported by the wheel on the opposite side. The pivoted support 4t is shown notched and when that side of the device is raised the shoulder of the first notch is available for retention and supporting purposes, this shoulder being,- designated by 6, Fig. 1. With the load thus supported on one side 1922. Serial no. 551,543.

by the support the. operator may next li'ifi on the handle to his left, bringing; the other support into play. At this stage both wheels will be free from the step below but will remain pressed against the edge ot the step above by reason. oi" the leaninuposition at the supports. Then the operator again lifts the side to his right until the next shoulder 7 becomes operative for retention purposes. The pivoted supports may he of any practicable length and provided with as many notches as desired. it is obvious that the device and its load may in the foregoing manner be negotiated upward. to a point where the wheels will roll onto he next step above, when the operation is repeated until the top is reached.

In Fig. 2 the device is shown resting on two steps, one side being supported by the wheel on one step while the other side rests on the pivoted support l: standing; tw, ste i below. in practice it is not found necessary to have the -:upports long; enor '3. to elev; the bottom of the whee. of the step above as the opei draw the wheels onto the a well onto the edge 1'. the same.

In practice I provide the pivoted pports with stao'gered notches or shoulders and as the handled end oi the frame is manipulated from side to side by the operator the pivoted supports act as a tulcrum also and in order that the load in ay he tililQl'l on the supports without sliding the adjacent wheel sideways against the step above I provide suihcient play between the frame and wheel to permit of a rocking; movement without any such result, this feature beingwell illustrated by Fig. 9.

The tor ugoin g desl'rihos the Jotia vice a d uwlluul Hl load l w equally satista'tory resul In practice the pivoted supports may be attached to other points than the axles of the wheels and in tact the stair ascending purpose oi my invention, may he accomplished with elements other than wheels adapted to serve the smile or similar purposes on the stairs and I do not wish to be limited to the construction shown but in practice I combine the stair ascending feature with a conve ance ada ted for ordinal" use and for conveying cans down stairs. 'l heretore in the device illustrated 1 provide means for converting the device into a handy truck or conveyance by enabling the operator to throw the pivoted supports into and out of the way position except when needed for stair climbing purposes. For this purpose I provide the retaining hooks 8 and 9 which are attached to the "frame. A projection, as illustrated by 10, Figs. 1 and 3, may be provided on the pivoted end of the supports which will enable the operator with the toe of his shoe to throw the supports over into the hooks '8 and 9, leaving them in position illustrated in Fig; 3, this method of manipulating the supports with the foot being exceedingly advantageous when the operator has a filled can on the truck.

Claims:

1. An ash can stair device comprising load retaining body having hand holds, ground supporting means and provided with pivoted supports oppositely attached thereto with their free ends extending be yond the point of ground rest and adapted to catch on the stairs and sustain the load on one side while the other side is being moved upwardly and forwardly by the operator, substantially as and for the purposes set forth.

2. An ash can stair device comprising load retaining body adapted to rest on the stairs and having pivoted supports oppositely attached thereto with retaining shoulders on their under sides adapted to catch on the steps to retain the load pn one side while the other is being moved upwardly and :lorwardly by the operator substantially Y as and for the purposes set forth.

3. An ash can stair device comprising load retaining body adapted to rest on the stairs and provided with supports pivotally attached thereto opposite each other '\vithnotcl1es in their under side adapted to catch on the steps and sustain one side of the device while the other is being moved upwardly and forwardly by the operator.

4. An ash barrel truck having supports pivot-ally attached to the axles with their free ends extending beyond the rims oi' the wheels and adapted to catch on the steps and sustain the load on one side while the other isv being moved forward by the operator.

5. A stair ascending device comprising hand controlled load retaining body adapted to bear, and move on the stairs and provided on its under side with oppositely arranged detents pivotally attached thereto and adapted to catch on the steps alternately to prevent one side from slipping'back :while the other is moved upwardly and forwardly by the operator.

6. A stair ascending device comprising handled load retaining body adapted to move on the stairs and provided on its under side with oppositely positioned detents attached thereto and adapted to catch on the steps alternately to sustain the load on one side while the other is moved upwardly and forwardly by the op'eratorx' CALLO .D. FAHRNEY. lVitnesses CAROLINE HAMMETT, JOHN BUOKLER.
