AUTOMATIC WAGON-BRAKE.
Specification of Letters Patent.
Patented May 23, 1916.
Application filed. September 25, 1915. Serial No. 52,628.
To all whom it may concern Be it known that I, Janus M. DAvIs, a
citizen of the United States, residing at Charlottesville, in the county of Albemarle and State of Virginia, have invented certain new and useful Improvements in Automatic Wagon-Brakes, of which the following is a specification, reference being had to the accompanying drawings.
7 This invention comprehends certain new and useful improvements in wagon brakes of the type called automatic and it has for its primary object a durable and very efficient construction of device of this kind, the parts of which are so arranged that they may be readily applied to the vehicle and automatically brought into play when desired as for example, when the vehicle is going down hill, the parts being further arranged so that when the vehicle is being hacked and the tongue turned to the right or to the left, the device will not operate to set the brakes and consequently the backing of the vehicle will not be interfered with.
The invention has for a further object an improved construction of brake of this character which may be very effectively applied independently of the driver of the vehicle and applied in proportion to the need for abraking action, which will be found unfailing inservice and which can be easily applied to any wagon with a tongue arranged for two horses or more and adjusted to any length of tongue or pole coupling. And the invention also aims to generally improve devices of this class so as to render them more useful and commercially desirable.
l i ith these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements, and combinations of the parts that I shall hereinafter fully describe and claim.
For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a wagon equipped with the improvements of my invention. Fig. 2 is a top plan view thereof,
arts being shown in difierent positions in full and dotted lines. Fig. 3 is a transverse sectional view, the section being taken substantially on the line of Fig. 2. Fig. I is an enlarged detail view of the front portion of the tongue and parts connected thereto. Fig. 5 is a bottom plan view thereof; and Fig. 6 is a fragmentary detail of parts hereinafter more specifically referred to.
Corresponding and like parts are referred to in the following description and designated. in all of the views of the accompanying drawing by like reference characters.
In carrying out my invention I apply to the tongue T of the wagon a preferably tubular rod 1 which constitutes the forward or tongue section of the brake apparatus and which is so arranged and connected to the tongue that it may be moved readily longitudinally thereof to a predetermined limited extent. In the present embodiment of the invention, the front section 1 is guided at any desired points by means of eyes or rings 2 depending from the tongue T as shown, and the forward end of the section 1 is movable in and guided by the depending apertured ears 3 of a bracket at which is secured to the tongue or pole at the forward extremity thereof by screws or similar fastening devices, said bracket being preferably formed with an upwardly extending plate 5 secured directly to the forward extremity of the tongue, as shown. In order to limit the'movement of the section 1 relative to the tongue, a collar 6 is mounted upon said section between the depending ears 3 and is secured in place by a set screw 7 the abutment of this collar against either of the ears manifestly determining the extent of movement of the forward section. Secured to the forward end of the section 1 above referred to is a latorally elongated ring 8 provided with a shank 9 which fits within the tubular section 1 and is secured therein in any desired way, the ring 8 being designed to have the breast chains secured thereto.
The forward section 1 of my improved brake apparatus carries at its rear end an extensionmember 10 which in function and operation forms a part thereof, said extension member being preferably in the form of a solid rod, one end of which is inserted within the rear end of the section 1 and secured therein at any desired adjustment by means of a set screw 11, whereby the device can be used with tongues of different lengths. The extension member 10 is guided in its longitudinal movements by passing through an opening formed for it in a transc indicated at 14c for engagement with the prof erably tubular rod 15 which constitutes the versely extending bar 12 which is secured to the hounds H, as best seen in Fig. 2 and after passing through the supporting bar 12 the extension member is inclined downwardly as indicated at 13 andis then extended,at a lower elevation rearw'ardly, as
rear section of the braking apparatus. This rear section is guided underneath the reach or "coupl ng R bymeans of eyes or r1ngs16,
as shown, andisprovided at its rear end with an extension member-17 in the formof a preferably solid rod which is adjustably mounted in the rear end of thesection 15 and held therein by a set screw 18, as clearly illustrated in the drawings. The rear end v of the extension member 17 of the rearsec-- tion .15 is connected inany desired way to the brake bar 19 which is suspended from lap rings 20 as shown and to which contractile springs 21 are fastened, said springs exerting a tension on the brake bar so as to tened to the forward section 1 at or about the point 23 in any desired way.
From the foregoing description in connection with the accompanying drawings,
the operation of my improved wagon brake will be apparent. Inthe practical use of theapparatus, whenthe vehicle goes down hill, and the horses naturally hold back, the
. connection of the traces and the forward section -1fof-the brake apparatus will move said section rearwardly, this movement be 7 ring limited by-the collar 6 in the bracket 4,
v the holding back movement of the horses, -which is proportionate to the declivity down and the rear movement of the forward section '1 will cause itseXtension member 10 a to engage, with its rear and depressed end, the forward end of the rear section 15, the latter being thereby pushed rearward and the springs '21 expanded and the bar. 19 moved rearwardly so that the blocks or shoes 22 will engage the peripheries of :the rear ground or traveling wheels. Naturally which the wagon is traveling will act proportionately upon the braking apparatus and secure the required braking action upon the wheels.
It will thus be seen that I have provided 7 a verydurable and eflicient construction of automatic wagon brake, parts of which can It is further to be noted that a driver never backs his teamrexcept for the purpose of changing the position of'his wagon or backing up-to a barn. In either case he will invariably turn the team to the right or to the left.
tion shown by dotted "lines in Fig. 221ml; it
L will be observed that the rear end ofthe eX-c 'VV hen this is .done the front of the Wagon will of'course assume the posi-' tension member 10 of the forward section 1 will then be out of alinement with therear section 15 and the teamcan be backedywithout applying-thebrakes. I
lVhile the accompanying drawings illustrate what g-Ibelieve to he the preferred embodiment of invention, it is to be underto but that various changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of theinvention as defined -;in the appended claim. ,Iclaim: v a I The combination with ajwagon-ru-nning gear and. a tongue connected thereto, of a stood that the invention isnotlimited therebrakeactuating means therefor, said actuatmg means compr sing a rear section movably supported by the running gear and adapted to apply the brake-upon a straightline rearward movement, and a movable -for-,
