SPECIFICATION forming part of Letters Patent No. 603,387, dated May 3, 1898. yApplication filed November 18, 1897. Serial No. 658,980. (No model.)

To @ZZ whom tpm/ay concern:

Be it known that I, CHARLES H. SwANK, a citizen of the United States, residing at Linville, in the county of Rockingham and State of Virginia, have invented anew and useful Tongue-Support, of which the following is a specification.

The invention relates to improvements in tongue-supports. y

rI he object of the present invention is to improve the construction of tongue-supports fory harvesters and .other heavy agricultural machinery and the like and to provide a simple, inexpensive, and efficient one which will cushion a tongue and relieve the draft-horses of the weight of the same.

A further object ofthe invention is to provide a tongue-support which will be capable of adjustment to support a tongue at the proper elevation and adapted to yield to the movements of the same.

Another object of the invention is to provide means for adjusting the parts to take .up the wear of the same. f

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1-is a side elevation of a tongue-support constructed in accordance with this invention and shown applied; to a tongue. S'Fig. 2 is a vlongitudinal sectional'view of 'thesame Fig. 3 is a horizontal section. Fig. 4 isa sectional view on line 5 5 of Fig. 1. Fig. 5 is a sectional View on line 4 4 of Fig. 1.

Like numerals of reference designate corresponding parts in all'the figures of the drawings.

1 designates the tongue ofthe harvester or other heavy agriculturalmachine; but the tongue-support may be applied to any other machine or the like where it is desired to relieve the draft-horses of the weight of the tongue. A vertical tube or housingy 2 -depends from the tongue 1 and has its upper end enlarged to form an attachment portion or flanges which present an upper inclined face to suit the inclination of the tongue. The top of the vertical tube or housing is recessed to receive the tongue and provide upwardlyextending flanges 3 to engage the side faces of the same, and it is. provided at opposite sides 'with perforations', to receive bolts 4, which pass through similar perforations of a top attachment'or clip plate 6, arranged on the upper face of the tongue. The attachment or clip plate 6 Vis recessed at its lower face to receive the tongue, and the bolts have their nuts 7 arranged on the upper face of the plate 6, their lower ends being provided with Arectangular heads which bear against the side faces of the vertical tube or housing 2,whereby the bolts are prevented from turning. The nuts 7 which are located at the top ofthe tongue, are in convenient position for lready access, and they enable the housing or tube`V 2 :to be drawn' up tightly against the lower face of the tongue.

.Within the tubular housing 2 is arranged a round standard 8 of a caster-wheel 9, and a spiral spring 10 is interposed between the lower face of the tongue and the top of the standard, being housed within the vertical 5 tube 2 and adapted to cushion the tongue when the caster-wheel is traveling over uneven ground. The upper end 11 of the standard 8 is reduced and receives a disk or washer 12, provided with an enlarged opening for the end 11 and detachably secured to the same by a pin or key13.

The upper portion 14 of the bore or opening ofthe tubular housing 2 is enlarged to receive the 'spring 10 and forms a horizontal shoulder'at its lower en'd, which .is engaged by the disk or washer, the enlarged opening of thelatter being for the purpose of permitting the necessary play of the standard, as hereinafter described. The disk or Washer limits the downward movement of the standard'in the tubular housing and prevents it from leaving the latter.

The standard, which is provided at yits bottom with a depending stud 15, is supported by a front inclined brace 16, extending upward and forward from the bottom of the standard and hingedly connected at its upper end with the tongue by means of a bracket 17 and a sleeve 18. The lower end of the inclined brace 16 is provided with a perforation to receive the stud 15 and is set an angle to arrange it horizontally on the bottom of the standard, where it is secured by means IOO of a nut 19, engaging the end of the stud 15, which is screw-threaded.

The upper end 20 of the brace 16 is threaded and receives the sleeve 1S, which is interiorly threaded and adapted to screw on or off the brace to vary the length of the same to take up any wear of the parts. The upper end of the sleeve is provided with an eye 21, which is pivoted between depending perforated ears of the bracket 17 by a removable bolt or pin 22, which is adapted to be readily detached to disconnect the brace from lthe tongue, so that the former may be readily adjusted by means of the sleeve 1S.

The brace forms a rigid support for the standard and the caster-wheel, and in order to permit the tubular housing and the tongue to move vertically on the standard for cushioning the parts the lower portion of the bore or opening of the tubular housing is enlarged above and below the center 23 at 2st and 25 at the front and back of the housing or longitudinally of the device to permit the standard to tilt rearwardly and have the necessary play, and the enlarged opening of the disk or washer contributes to this result. The bevcling or cutting away of the inner walls of the tubular housing at 2l and 25 forms a central horizontal circular ridge, which constitutes a bearing or fulcrum for the standard, and the transverse diameter of the lower portion of the tubular housing is not increased, so that the standard of the caster-wheel is permitted no lateral movement or play. Openings are provided at the front and back of the upper portion of the tubular housing to afford ready access to the pin or key, so that the parts may be conveniently separated and assembled without removing the tubular housing from the tongue.

The tubular housing is designed to be attached to the tongue in rear of the doubletree, and the bracket 17 is bolted or otherwise fastened to the same in advance of the doubletree, and as the tongue is arranged on a slight slant it may be raised or lowered by adjusting the support backward or forward. A vertical adjustment of the tongue is also obtained by means of the connection between the caster-wheel 9 and the standard 8. The standard is provided with a rearwardly-extending arm 2G, to which are detachably secured rearwardly extending side pieces 27 and the caster-wheel is journaled between the latter. The arm 2G is provided at opposite sides with annular series of lugs or teeth 28, and the upper ends of the sides 27 are provided with similar lugs or teeth 2.9,which interlock with the teeth 2S and form a ratchet connection to permit the side pieces to be arranged at any desired angle to the arm 26. The teeth 2S and 2f) are locked in their engagement by a transverse bolt 30, which passes through perforations of the parts and is adapted to be readily loosened when it is desired to change the adjustment of the side pieces. By swinging the side pieces downward the length of the tongue-support is increased and the tongue is raised, and by swinging it in the opposite direction the tongue may be lowered.

The side pieces 27 are laterally offset near their upper ends to increase the space between them, and they are provided at their lower ends on their inner faces with annular flanges 31, forming bearings and receiving the hub 32 of the caster-wheel. The lower end of the side pieces 27 are also perforated to receive a transverse axle pin or bolt 33, which connects the sides and which may be fastened by a key, nut, or any other suitable fastening device. In order to reduce the friction to a minimum, a bearing-sleeve or bushing 31 is arranged on the bolt or pin within the hub and interposed between the said side pieces to prevent the same from binding against the ends of the hub of the caster-wheel.

The invention has the following advantages: The tongue-support, which is simple, inexpensive, strong, and durable, is adapted to be readily applied to the tongue of a harvester or other heavy agricultural machine or the like and is adapted to relieve the necks of the draft-horses of the weight of the tongue. It is adapted to adjust the tongue to the proper elevation by being moved longitudinally of the same and by arranging the side pieces of the caster-wheel at the proper angle to the arm of the standard. It is iirmlysupported by the inclined brace, which extends from the bottom of the standard to the tongue, and the particular construction of the lower portion of the tubular housing permits the necessary backward-andforward play of the standard and at the same time affords a perfect bearing for the same to permit it to rotate freely in the housing without lateral movement. The upper end of the inclined brace is detachably hinged to the tongue, an d the sleeve maybe readilydiscolmected therefrom when it is desired to vary the length of the brace and take up any wear of the parts.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacricin g anyof the advantages of this invention.
