SLEIGH.

SPECIFICATION forming part of Letters Patent No. 682,934, .dated September 17, 190,1.-

Application filed April 20, 1901.

To t/Z whom t may concern' Be it known that I, JOHN A. HEINTZ, `a citizen of the United States, residing at Menomonie, in the county of Dunn and State of Wisconsim have invented a new and useful Sleigh, of which the following is a specification.

This invention relates to sleighs; and one object is to provide a construction in which the runners have an independent limited swinging movement, so that they'will accommodate themselves to uneven portions in the roadway.

A further object is to provide novel means for fastening the knee to the frame, so as to permit of a limited swinging movement of said knee, but securely hold the same against longitudinal movement and accidental displacement.

A still further object is to provide a construction in which the weight of the body is directly over the knees and runners instead of on an intermediate connecting bar or rod, as in the ordinary sleigh, and, furthermore, t employ springs in this connection which will absorb the jolts and jars to which the runners may be subjected. Y

In the following specification there is described the construction and operation of the preferred embodiment of the invention, and said construction is illustrated in the drawings which accompany and form a part of the specification; but it will be understood that such changes may be made as are within the scope of the appended claims.

In the drawings, Figure 1 is a perspective view of a front bob embodying the present invention. Fig. 2 is a vertical longitudinal sectional view of the same. sectional view. Fig. 4 is a perspectiveview of a section of the bearing-block. Fig. 5 is a detail perspective view of a detached knee. Fig. 6 is a detail perspective view of a modied form of knee and axle. Fig. 7- is a longitudinal sectional view through the same. Fig. 8 is a vertical cross-section ythrough the upper end.

Similar numerals of reference designate corresponding parts in all the figures of the drawings. v

ings, it will be seen that two runner-sections 10 are connected by an axle 11, upon which is supported spring-gear 12. The axle 11 is in the form of a continuous bar having'at its ends the spindle portions 13. The runnersections 11 each comprise a runner 14, hav*- ing a forwardly-upturned end 15 and carrying an upstanding knee 16, bifurcated at its lower end and embracing the runner and held against movement by the braces 17. The upper end of this knee is` provided with an enlarged transverse head or journal-boxing 18, having an opening 19 through the same to receive the spindle 13 of the axle.v The upper face of the box has an inset semicircular bearing-face 20, which forms a continuous tiange or shoulder 2l, and has a transverse notch 22, for the purpose hereinafter shown.

Located upon each journ al-box 1.8 is a bearing-block'23, which comprises an intermediate semic'ylindrical body portion 24, that bears upon the correspondingface 20l of the journal-box and is provided at its ends with collars 25, which surround the axle at the opposite ends of said journal-box. The edges of the semicylindrical body port-ion are normallyl spaced from the flange 21 of the journal-box, as shown in Fig. 2, and thus form abutting shoulders 26, which limit the swinging movement of the knee. The bearingblock 23 is rigidly iixed to the axle by means of a set-screw 27, that passes through the inner collar 25 and engages said axle, and also by means of a bolt 2S, that passes entirely through the outer collar and spindle and also serves as means for fastening a step 29 in place upon the bearing-block. Each bearing-block is furthermore provided intermediate its ends and directly above the knee with 'a transverse supporting-arm 30, the endsof which project upon opposite sides of said This arm is provided with a longitublock. dinally-disposedopening31,whichalineswith the transverse notch 22 of the journal-box 20. Bowed springs 32 connect the corre-V sponding ends of the opposite arms Y30, the ends of said springs being fastened to the arms by means of hanger-links 33, ,whichare pivoted upon bolts 34, that pass through the openings 31 of the arms andthe notches 22 of the journal-boxes. Securedto the springs IOO at their highest and central points is the fifthwheel 35, the lower section 36 ot' which is fastened rigidly thereto, while the upper section 37 is pivotally connected to the lower section by means of an integral journal-stud 38, which passes through the central opening in the lower section, and by a pivot-bolt 39, which passes through the entire wheel. It will be observed that the journal-stud 38 relieves the pivot-bolt of all strain. The bolster 40 is fastened upon the upper section 37 ofthe fifth-wheel and supports the body of the vehicle. By this construction it will be seen that the sleigh-knees ot' the opposite runners each have an independent swinging movement, which is, however, limited by the shoulders of the bearing-blocks that are rigidly attached to the axle and have no independent movement therefrom. These bearing-blocks also serve to hold the knees against `longitudinal movement and accidental displacement, and thus perform a double function. As a further security the pivot-bolts 34, engaging in the transverse notches 22 ot the journal-boxes of the knees, assist in both limiting the swinging movement and holding the knees against longitudinal movement, so that all other fastening means might be dispensed with, if desired. Perhaps the most important feature, however, is the manner of distributing the weight and placing it directly over the knees, so that the axle is entirely relieved ofthe same, and a much lighter structure can be employed. Furthermore, it permits the use of springs which will absorb the jar and pitch of the runners when passing over rough roads, and said springs distribute the weight on opposite sides of the knee.` In certain classes, however, it may be undesirable to employ springs, and the weight of the (body may be placed directly upon the axle, in which case the modified construction shown in Figs. G, 7, and S is employed. In this form the axle ll and spindle 18n are used; but the stationary shoulders 26, corresponding practically to the shoulders 26 of the above-described construction, are formed integral with said axle. The knee is ot' the same general construction, having the journal-box 1S, the stop-shoulders 21, however, being formed only at the inner end and coacting with the stationary shoulders26a of the axle, as in the former construction. This journal-box I8 is also provided with a transverse notch or opening 22a, through which passes a set-screw 34, that engages the axle and corresponds to the relatively stationary bolt 3l of the other construction. A-nut 25a is screwed on the outer end of the spindle. In this construction the fifth-wheel is designed to be secured directly to the axle.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape,

proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad vautages of the invention.
