BOLSTER-SPRING.
SPECIFICATION forming. part of Letters Patent No. 252,036, dated January 10, 1882 Application filed November 8, 1881. (No model.)
To all whom it may concern:
Be it known that 1, CHARLES A. HOWARD, of Pontiac, county of Oakland, State of Michigan, have invented a new and useful Improvement in Spring Attachments for Bolsters; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to whichit pertains to make and use it,reference being had to the accompanying drawings, which form a part of this specification.
My invention consists of the combination of devices and appliances hereinafter specified and described, and more particularly pointed out in the claim. I
It is the object of my invention to produce a removable spring-frame having semi-elliptical springs so constructed and arranged as tomake a convenient, elastic, and durable set of springs for use on a lumberwagon, sand or dirt wagon, or any other'similar wagon, and so made that when a heavy load is being carried all the springs are brought into use; but when the load is taken off and the wagon returning for another a part of the spring-power may be dispensed with, ifdesired. I accomplish these results by employing the mechanism illustrated in the accompanying drawings, in which Figure 1 is a view of the removable springframe, with 'springsattached, as it appears,
when adjusted to the bolster ofalumbr-r-wagon. Fig. 2 shows the same when detached from the bolster. Fig. 3 is a view of the spring-frame when the cross-spring is not in use, as is the case when the load isoft' the wagon. Fig. 4 is a separate view of one of the side pieces of the frame, showing another method of attachment of the spring thereto. tion where two cr0ss-sprin gs are employed instead of one, as in Fig. 1.
Ais the bolster, and B B the wagon-stakes, of a common lumber-wagon.
0 0 represent a removable longitudinal spring-frame composed of two side pieces,'D D, adapted to fit upon the bolster, said pieces having metallic plates screwed to their upper sides-to receive the wear of the cross-spring D.
E E are semi-elliptical spriugs, placed over the side pieces, with their length in the direction of the length of said pieces, and their concaveside toward the plated surface of the Fig. 5 shows a variaable as a ready attachment.
side pieces, each of their ends resting in a refcess formed by the upturned flange on the end other, and its ends to rest upon the metallic 1 plate, above described, when it is desired to employ it as shown in Fig. 1.
When the device is used upon a common lumber-wagon the removable frame :is placed in position upon. the bolster, and the body of the wagon will rest upon the cross-bar F.
It will be readily seen that as the spring D is directly over the bolster, two shorter springs of similar shape may be employed for the same purpose, each of these springs being pivoted to the cross-bar F in the same way as the spring D aforesaid, thereby allowing them to be turned aside when not in use. In this latter case the appearance of the device will be as shown in Fig. 5.
If desired, the springs E E may have their ends turned down over the ends of the side pieces, and have slots made in them, through which a bolt passes, thus enabling the spring to flex, but not permitting it to leave its place on the side piece. This method of attachment is perhaps preferable to the one shown in Fig. 1, being somewhat cheaper.
A latchet device of any suitable construction may be employed to hold the cross-spring D in position at right angles to the cross-bar when not in use.
tion that a removable frame, with a set of springs arranged in the manner shown, and
capable of ready attachment to a wagon-bolster, is an article of great use and value. This device may be made separate, so as to be readily placed upon the bolster of any ordinary wagon; or, if desired, the side pieces may be framed into the bolster and made a permanent fixture. I prefer, however, to make it remov- So, also, the top of the side pieces may or may not be shod with 1 It will be apparent from the above descripmetal, or may be shod only where the ends of the springs wear upon them It is apparent that across-piece similar to D may be interposed between the two side 5' pieces, and be provided with a spring in like manner. For ordinary light work the crossspring may be omitted, and the removable frame consist only of the side pieces and their springs united by the top bar parallel with the IQ bolster. y
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The removable spring attachment for a wag-
