Serial No. 659,754.
claimed, and which are illustrated in the accompanying drawings, in which:
Figure l is a left-hand side elevation of my improved concrete spreader. Fig. 2 is an upper plan view of the same. Fig. 3 is a detail elevation of one of the upwardlybent axle-sections.
Similar characters of reference designate corresponding parts throughout the several views.
My improved spreader is of the push-cart type, having a hollow metallic body a supported on a pair of carrying-wheels wf Each wheel to is rotatably mounted on the cylindrical horizontal outwardly-directed portion of an axle-section h, each section h being bent upwardly, then flattened to produce fiat fork-members g, and then secured to the side of the box a by means of a staple z' and rivets y. This manner of dividing and mounting the parts of the axle conduces to stability and strength, without any interference with the functions of the spreader.
The box a of the spreader has a rearwardly-inclined bottom-plate 2, whose rear edge a is extended a short distance beyond the plane of the rear end of the box for a purpose to be indicated later. The forward part of the box a is supported on legs t having braces .9, said legs having a plurality of pin-holes r to adjustably receive a pin 79 also seated in an orifice in the lower rear end of a brace 0, the upper forward end of said The lower part of the rear end of said box a is open, but said opening is adapted to be closed by means of a swing drop door I) hinged to the rear plate by means of the hinges The height of the door is such, that its lower horizontal edge may scrape over the projecting part a of the box bottomplate a, and thus, in cooperation with the forwardly-flanged .side edges of the door, makes a tight fit over said opening. The said door is manipulated for opening and closing by the following mechanism: The character Z designates a shifting-lever composed of two parallel arms connected by a cross-piece, the cross-piecebeing located just above the handle-bars n and lying a distance forward of the front end of said'box a. This cross-piece is thus located conveniently to be thrust upwardly by any means or an upward blow received by it from a knee of the user. said lever are pivoted to brackets w on said box at pintles o, and at a short distance anterior to said pintles at a bent part of said arms the upper ends of the connecting-rods e are pivoted to them at 70. The lower ends of the connecting-rods e are pivoted at d to the lower side parts of the door I). The arrangement of the lever-arms and connectingrods is such that when the arms are moved forward and downwardly to the position shown in the full lines in Fig. 1, the pivot is on each side passes the medial line from the pivot o to the pivot 01, and secures the door in its closed position. However, when the arms Z are raised to move the rods 6 to the The rear ends of the arms of rear of the pivots o, the combined weight been discharged, it is only necessary to shift the arms l back to their former position, the rearward positions of the moving parts above described being indicated by the dotted lines in said Fig. 1.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:
In combination, a hollow box mounted pivotally on carrying-wheels, having a hinged outwardly-swinging door, having also forwardly directed handles, a bailshaped lever having its members pivoted 0n Signed at WVaterloo, Iowa, this 26th day opposite sides of said box and its transverse of October, 1911.
