WHIFFLETREE.
SPECIFICATION forming part of Letters Patent No. 732,320, dated. June 30, 1903.
Serial No. 154,094. \No model.)
To all whom; it may concern:
Be it known'that I, ABRAHAM CALVERT SOARR, a citizen of Canada, residing at Harriston, in the county of Vellington and Province of Ontario, Canada, have invented certain new and useful Improvements in VVhiffletrees, of which the following is a specification.
' My invention relates to improvements in whiffletrees for vehicles; and it principally consists of the hollow metallic construction of the doubletree and the swingletrees, which comprise the whiffletree.
The object of my invention is to provide a hollow metallic whitfletree which shall combine strength, durability, and lightness.- I attain this object by the device illustrated in the accompanying drawings, in which Figure 1 is a plan of my improved whiffletree in its completeness. Fig. 2 is an enlarged plan of one end of the doubletree. Fig. 3 is an enlarged plan of one end of a swingletree. Fig. 4 is an enlarged sectional end elevation of the doubletree through a central part thereof, showing also the section of a woodblock, the swingletrees being similar. Fig. 5 is an enlarged plan of the central part of thedoubletree, the upper plate being broken away to show the wood block in the interior, the swingletree being similar. Fig. 6 is an enlarged sectional end elevation of a doubletree or a swingletree of modified construction of a single piece of sheet metal.
Similar letters refer to similar parts throughout the several views. 7
In the drawings the doubletree is indicated by A and the swingletrees by B. At each end of the doubletreeis a clevis 2, pivotally connected at 3 to a rear plate 4. The central part of the swingletree B is provided with a staple-eyebolt 5, which extends through the swingletree and fastens thereto against a washer-plate 6. The clevis 2 is adapted to allow the rear eye part of the staple-bolt 5 to swivel therein. The ends of the swingletrees B are provided with U-shaped closed end plates 7, which cover the ends of the swingletrees and extend a suitable distance on the front and the rear sides thereof and flush with the swinglctree. The clevis-hooks Snear each end of the swingletrees are pivotally connected at 9 to the rear part of the U -shaped plates 7, The clevis-plates 4 and 7 are boltedor riveted to their respective parts of the whifl'ltree, as is desired.
10 is an eyelet-plate secured to the front central part of the doubletree for attachment to avehicle, and the clevis-hooks 8 of the swingletrees are for attachment of the horse side straps.
The important part of my invention consists of the metallic construction of the doubletree A, together with the swingletree B, the top and the bottom of each being of a single thickness of metal and the sides thereofv that is, the front and the rearare of double thickness of metal and secured together, as especially shown in Fig. 4 of the drawings.
The metallic doubletree, together with the metallic swingletrees, are formed with a horizontal top plate 12 with side flanges 13 at about right angle thereto and forming one single piece of metal. The bottom or under side 14 of the doublet-rec, together with the swingletrees, are formed with side flanges 15, which fit snugly into and between the side flanges 13 of the upperpart. The side flanges 13 and 15 may be secured together at approved places by means of rivets 16. (Shown in Fig. 4 of the drawings.)
The closed U-shaped end plate 7 of the swingletrees may be applied to the ends of the doubletree, if deemed expedient.
It will be obvious that the doubletree and the swingletrees are of similar construction, though differing in size and proportion.
The central part of the doubletree and the swingletrees are provided with suitable blocks of wood 18, which may be six or eight inches in length, more or less, in full-size whiffletree, in order to strengthen the middle part thereof, more especially in the doubletree part. The wood blocks 18 referred to are advantageous when the whiffletree is constructed of light material. \Vhen the wood blocks are applied in the whiffletree,the construction of the whiffletree may be of lighter materiahthereby adding no additional weight in obtaining the desired resnltsthat is, sufficient strength with a minimum of weight of whiflietree.
It will be noticed that the upper part or top 12 of the whiffletree, together with the sides 13, entirely cover the exposed parts thereof, thereby presenting in appearance one solid piece of metal without joint or opening to the weather. This feature is important.
It will be obvious that throughout the body of the whiifletree the upper and the lower body parts 12 and 14:, respectively, is each of single thickness of metal and that the sides or flanges thereof, 13 and 15, respectively, when in position form a double or two thicknesses of metal, thereby adding great strength to said sidesthat is, to the front and to the rear of the whifiletree. This feature is desirable in a whifiletree and especially so in the front part thereof. The metallic section throughout the whifiietree from end to end is similar and of identical construction, comprising upper and lower single plates and the front and rear sides of double plates.
In Fig. 6 of the drawings is shown a seetional end elevation of a lighter whiffletree, consisting of a continuous single piece of metal comprising the top 20, the bottom 21, the rear side 22, and the front side 23, which is double. The rear side 22 is of a single thickness of metal continued at right angle from the top 20, and the interior flange 24 is continued from the bottom 21, which is a continuation from the rear side 22 and is parallel with the top 20. The flange 2a extends to the top plate 20 on the inner side of the front 23, thereby presenting a single thickness of metal to the top, a single thickness to the rear side, and a single thickness to the bottom side and two thicknesses of metal to the front side of the whiffletree. The block 18 in this section of a whifiletree, as shown in Fig. 6 of the drawings, is similar to the block 18, as shown in Fig. Iof the drawings, and for the samepurpose of strengthening the whiflletree in the central parts thereof.
Various changes in the form, proportion, and minor details of this invention may be resorted to without departing from the spirit and scope thereof.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
1. A whifiietree for vehicles, comprising ahorizontal top plate with sides extending downward, a horizontal bottom plate with sides extending upward and adapted to fit between the sides of the top plate and fasten therein, substantially as set forth.
2. A whiflietree comprising horizontal upper and lower plates, side flanges extending downward from the upper plate and side flanges extending upward from the lower plate, said flanges of the lower plate adapted to fit between the flanges of the upper plate, substantially as set forth.
3. A metallic whiflietree comprising an upper plate and a lower plate; sides extending from said plates and adapted to fit one against the other whereby each said side shall comprise two thicknesses of material, substantially as set forth.
4. In a whiflietree of the class described, a U-shaped plate adapted to fit over the end of the whiflletree and fasten thereto and a elevis pivotally connected to the rear side of said plate, substantially as set forth.
5. In a whifiletree an upper plate with downwardly-extending sides, a lower plate with upwardly-extending sides adapted to fit between the downwardly-extending sides and fasten thereto, and a block adapted to fit between said sides, and fasten thereto, substantially as set forth.
6. Ina whifiletree a top plate, a rear side extending downward from the plate, a bottom continued from said side and parallel with the top, a front flange extending downward from the opposite side of the top plate, and an upward continuation from the bottom plate and adapted to fit against the inner side of said front flange and fasten thereto, substantially as set forth.
7. In a whiflletree an upper horizontal plate, a lower plate parallel therewith,-a rear plate forming a part of the same, a front side continued from the upper plate, a flange continued from the lower plate and adapted to fit against the inner part of the front side, and a block inclosed between said sides, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
ABRAHAM CALVERT SCARR.
