moroarnucx Bon Specification of Letters Patent.
llaten'ted Dec. 3 0 1913.,
Application filed December 23, 1912. Serial Ito. 1733323.
To all whom it may concern;
Be it known that I, ROBERT S. McKnAGn, a citizen of the United States, residing in the city and county of Denver and'State of Colorado, have invented certain new and useful Improvements in Motor-Truck Bodies and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the being'had to the accompanymg drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates tomotor particularly such as are adapted for hauling coal, and has for one of its objects to provide a construction in which the coal box may be raised and lowered, and to provide means for accomplishing this purpose, which means are of such a character as to be readily ada pted' for the application of power thereto.
' Another object of the invention is to pro .vide a simple and etlective'means for suporting a coal chute in a convenient position slow the trap door'opening-of the coal box.
Other objectswill appear hereinafter as l proceed With the description of that embodiment of the invention, which, for the purposes of the presentapplicatlon, I have illustrated in the accompanying drawings, in which: 1
Figure l is a view in side elevation of a portion of a truck embodying my invention. Fig, 2 is a section taken upon line 2, Fig. 1.
Fig. 3 is a side View showing the coal box in section and the sub frame with parts removed to disclose to view the operating mechanism. Fig. 4t is a section taken upon the line 4%, Fig. 3, and lookin in the di-- rection of the arrow. Fig. 5 is a detail view, partly in section, showing the means for supporting a coal chute. I
The same reference numerals refer to like parts in the several views.
In the drawing the numeral 4 designates the ordinary truck chassis, mounted upon ground wheels 8, of which I have illustrated only one, my improved truck body being adapted to rest upon the chassis to which it issecured by any suitable means. The subframe of the truck body is formed of side bars 5, 5, which are suitably spaced at the front and rear ends by angle-irons 6 and .7.
truck bodies,
bar .10, which extends across the upper ends or" each pair of posts 9.
The coal box 11 is preferably constructed of sheet metal, and in the embodiment illus' tratcd is reinforced upon its under surface by a central longitudinal I-beain l2, trans,
verse Lbeams l3 and 14:, and transverse channel irons 15 and 1c. The E-beams 13 and 1% and the channel irons l5 and it in the lowered position of the box, rest upon the side bars 5, 5 of the sub-frame.
To the bottom of the coal four corners, are secured short angle bars 17, to the vertical sides of which are attached plates 18, which are reinforced by shorthorizontally exteiulingangle bars 19, the plates 18 and the angle bars 19 extending longitudinally beyond the box 11, lapping outside of the respective posts 9,v while the vertical angle bars 20 are mounted upon the 'plates 18"to lap the var sides of the front posts 5) and the front sides of the rear posts I 9. By the means just described the box 11 is guided during itsvcrti'cal movement.
Mounted across the side bars 5, 5 are channel irons 21, 22,- 23, 12 i, 25,'and Within the channel 21 is mounted an inverted U- shaped bracket 27, in which is fixed one end of a guide rod 28, and in which is rotatably mounted one end of a screwQS), the middle portion of which is rotat al v mounted in a bearing 30 supported by" the channel 23, while the opposite endis rotatably mounted in a bracket 34:, in which latter bracket is also fixed one end of the guide 35. One half of the screw 29 cut right-handed the other half is cut lcfbhanded. The a jacent ends of the guides 28 and 35 mounted rcspectivel in the brackets 37, supported by the channel irons 2s and A gear wheel 38 is secured upon the screw 29 near the central bearin 36 saidgear meshing with a small gear 1Ll1 gear 40 is mounted to rotate with t a sn'iall 39 and meshes with small gear ll tired to a shaft 42,-which is arranged to be rotated by an electric motor 43. Although I have described more or less in detail the mochenism for rotating the screw 29, it should be I understood that this particular mechanism box, near. the
the motor 43 is started in the proper direction to rotate the screw 29, to cause the blocks 44 to move upon the guides 28 and 35 toward the middle of the truck, whereupon a pull will be exerted upwardly at the points 50 to raise the box 11. hen it is desired to again lower the box the motor l3 is caused to rotate in the oppositedirection.
I claim as my invention: I I
1. In a truck body, a sub-frame, a'box, uprights mounted upon the sub-frame, horizontal guides arranged upon the sub-frame, one end of each guide being arranged near the base of one of the uprights, a block slidably mounted upon each guide, a sheave upon the sub-frame near the base of each upright, a sheave near the upper extremity not essential to my invention, which in this respect is limited only by the scope of the claims hereunto appended.
Blocks 44s have each an internally threaded opening 1n their lower portions to engage the threads of the screw 29, and a smooth opening in their upper portions to slide upon the guide rods 29 and 35 respectively. Upon either side of each block 44: are ears lo 45, to each of which is attached one extremity of a cable or other flexible connection 46. Each of said cables passes around the lower side of a sheave 4:7 which is anchored to the angle bar 7 by means of an eye-bolt 48. The cable after leaving the I sheave 47 passes upwardly and over a sheave 49, which is hung from the T bar 10 by any suitable means. The cable then passes downwardly and is secured at 50 to a bracket 51, depending from the bottom of the truck box 11. By thus attaching the cable below the bottom of the box proper I am enabled to cause the raising of the box to an elevation where its bottom will be level with the tops of the T bars 10, as shown in dotted lines in Fig. 1.
In the floor of the box 11 I provide a trap door 52', which is hinged art-53 to the central longitudinal I beam 12: Upon this I beam 12 is mounted ahanger 54, preferably of strap iron, which is given a quarter turn at 55, thus causing the lower portion of the hanger to extend parallel to the I beam 12. When coal is to be unloaded from my improved truck the hooks 56 of a chute 57, are supported upon the horizontal portion of the hanger 54; said chute then occupying a osition directly below the trap-door 52, .which when released will fall into the chute. In order to latch the trap-door 52 in its closed position, I provide an angular plate 58 upon the side of the box 11, and a pivoted latch bar 59 upon the trap-door, the said parts being held in positlon, as illustrated in Fig. 1, by means of a hook 60, pivoted at 61.. From the foregoing description it is"believed that the operation of my improved truck will be apparent. The normal position of the box 11 is that illustrated in Fig. 3, and in full lines in Fig. 1. When coal is about to be unloaded tached to each block extending aroun i the lower portion of the lower adjacent sheave, around the upper portion of the upper adjacent sheave, and downwardly to a lower portion of the box, to which it is attached, and means for movin the blocks simultaneously along the guides away from or toward the uprights.
2. In a vehicle body, a sub-frame, a wagon-box, uprights mounted upon the subirame at the front and rear thereof, a horizontally arranged rotatable screw mounte longitudinally upon the sub-frame, said screw being reversely threaded from its ends toward its middle, an internally threaded block mounted upon said screw on either side of the middle, means for preventing said blocks from turning, a sheave mounted at the upper end of each upright, a sheave mounted upon the su -trame below each of said first-mentioned sheaves, and a tlexible tending below the adjacent lower sheave, up
,to which it is attached, and means for T0- tating said screw.
In testimony whereof I afiix my signatur in presence of two witnesses.
