ALBERT MOSES BARRIER, OF BROOKLYN, NEW YORK, ASSIGNOR TO EASTON GAR CONSTRUCTION (20., 011 EASTON, PENNSYLVANIA, A CORPORATION 01? PENN- SYLVANIA.
DUMFING-GAR LATCH.
T0 aZZ whom it may concern:
lie it known that l, ALBERT M. FARRIER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and improved Dumping-Car Latch, of which the following is a full, clear, and exact descrip tion;
'1 his invention relates to improvements in dumping car latches, and more particularly to improved means for holding the car body in an upright position or locking the same in a full dumping or partially tilted position.
A further object is to provide an improved construction or" the latch which is automatically thrown by the car body as the latter moves to full dumping position to secure the car body in this position and hold it until manually released.
A further object is to provide a latch of the character stated, which can be manually operated to lock the car body in a partially tilted position which is desirable in many cases for loading or unloading.
With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings- Figure 1 is an end view showing the body in normal upright position;
Fig. 2 is a side view of Fig. 1;
Fig. 3 is an end view showing the body in full dumping position;
Fig. 4 is a similar view showing the body in partially dumping or tilted position;
Fig. 5 is a fragmentary view in section illustrating a latch and its mounting; and
Fig. 6 is a plan view of the latch supporting bracket 14.
1 represents a car or frame and 2 the body which is supported on toothed segmental rockers 3 at its ends, said rockers mounted to roll on rack bars 4 secured to the car frame 1 and are provided at their ends with studs 5 adapted to be engaged by my improved latches 6.
I would have it understood that I may employ any desired number of latches 6, but find that one at each end of the body and diagonally opposite each other will in Specification of Letters Patent.
Patented Jan. 25, 1921 Application filed October 3, 1919. Serial No. 328,093.
many cases answer all purposes, but it may be, of course, desired to provide two latches at each end or at one end.
The latches 6 at their free ends are given a general parabolic curve 6 so that they rest against the outer surfaces oi the rockers 3 and normally hold the body in an upright position, as shown in Fig. 1. The latches 6 are pivotally supported on pins 7 mounted in brackets 14 fixed to or constituting part of the rack bars a and said latches are made with projections 9 extending through slots 10 in the brackets 1d and are limited in their pivotal movement in one direction by means of flanges 8 on the ends of the brackets 14.
Each latch 6 is provided in its under face with two or more recesses 11 and 12 and the latches are moved by means of rods 13 mounted in the frame 1 and connected to the extensions 9.
The operation is as follows: Assuming the parts to be in the position shown in Fig. 1 and it is desired to dump the body to the right, the right-hand latch 6 is moved by the rod 13 to the dotted line position shown in Fig. 1. In the movement of the body 1 to the position shown in Fig. 3, the righthand stud 5 will strike the projection 9 and throw the latch inwardly with the recessed portion 12 of-the latch engaging over the stud 5 securely locking the body in the position shown in Fig. 3. The latch will hold the body in this position and even though the contents of the body should not be fully discharged, the car can be run backward or forward to an advantageous position for completely emptying the body. This is desirable when dumping on trestles or other like places and where sticky material is being handled.
To return the body to its normal position, the rod 13 is operated to release the catch and when the body is in an upright position, the catch will be moved to the position shown in Fig. 1, and by reason of the engagement of the parabolic curved ends 6' of the latches with the rockers 3. the body will be securely held in an upright position.
The body can be locked in a partially tilted position for loading or emptying, as shown in Fig. 4 by manually manipulating the rod 13 and latch 6 so that the stud 5 is engaged in the recessed portion 11 of the latch. V
In some cases it might be found desirable to dispense altogether with the operating rod 13 and manually operate the latch in any desired Way. The flange S of the bracket 14 operates to limit the pivotal movement of the latch in both directions, as Will be readily understood.
1, of course, do not limit myself to any particular number of recesses in the latch as it is obvious that by providing various recesses, the body may be secured at various angles.
Various slight changes may be made in the general form and arrangement of parts described Without departing from the invention, and hence 1 do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
I claim 1. The combination With a car, a tilting body on the car, and rockers secured to the ends of the body and supporting the body on the car, of latches pivotally connected to the car located at diametrically opposite corners or" the car and adapted to engage the sides of the rockers to normally hold the body in upright position, lugs on the rockers, and said latches having recesses therein adapted to receive therlugs oi": the rockers and secure the body either in a partially tilted position or in a full'dumping position.
2. The combination with a car, a tilting body on the car; and rockers secured to the ends of the body and supporting the body on the car, of latches pivotally connected to the car located at diametrically opposite corners of the car and adapted to engage the
