WAGON PULL DEVICE.
SPECIFICATION forming part of Letters Patent No. 762,311, dated June 14, 1904.
Application filel February 11, 1904:. Serial No. 193,039. (No model.)
To all 1072 0771, it may concern.-
Be it known that 1, WILLIAM W. HorKINs, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in l Vagon Pull Devices, of which the following is a specification, which, together with the drawings, fully describes and illustrates the construction, functions, and operation of the invention.
One object of the invention is to provide a suitable device operative to pull or draw wagons and other vehicles up hills, grades, and inclines and provided with mechanism for making automatic engagement with some predisposed appliance connected with the wagon or vehicle while the pull device is in motion and without manual adjustment other than that required to place the said appliance in position to be engaged by the pull device.
Another object is to provide a device of thischaracter adapted to be mounted and operated below the level of the street or road and comprising a chain, cable, rope, or similar object with means for moving the same up the hill, grade, or incline with sufficient force to pull or draw any vehicle or wagon, loaded or not, and having devices attached thereto at intervals with means for raising them above the street or road-bed for engagement with some suitable connection on the wagon at the base of the declivity and arranged to disappear below the surface a short distance up when not employed to draw any wagon or vehicle.
A further object is to provide in a device of the class mentioned suitable means for automatically releasing the wagon or vehicle at the top of the hill, grade, or incline without stopping either the wagon or the draft appliance.
In the drawings, Figure 1 illustrates the catch device and the means whereby it is raised to engage with the appliance attached to the wagon. Fig. 2 shows the catch device in engagement and the position of the parts just prior to being released from the wagon at the top of the hill or grade. Fig. 3 is a top view of a portion of the apparatus. Fig. 4 is a cross-section of a portion of the device, showing the engagement with the appliance on the vehicle. Fig. 5 is a full sectional view with the catch device raised above the street or road surface. Fig. 6 is a view of complete apparatus in operation.
Essentially this apparatus consists of a chain or cable 1, preferably in endless form and mounted on suitable propelling devices, such as wheels or pulleys 2, drawn by any desired motive power. At intervals along the part 1 there are attached catch devices, the preferred construction of which is shown in the drawings, each comprising an angular member 3, pivoted at one end to the part 1 and the opposite or free end projecting upward when traveling up the hill or incline and downward when descending, as may be clearly understood by referring to Fig. 6. On
the front side, near the free end of the member 3, there is formed a notch 4, adapted to receive the draft appliance extending from the wagon or vehicle, and the lower side of the said notch extends forward, forming a shoulder 5,
which is slightly above the street or road surface when the device is in use, the purpose thereof being to hold the part which is in engagement therewith out of contact with the surface and to form an abutment for the free end of a spring-actuated jaw 6, attached rigidly to a transverse rod 7, supported by the member 3. Said member 3 is in two pieces, one attached to each side of the chain or cable 1, and the free ends thereof being bent together to form shoulders 8, just below which the rod 7 is mounted. The jaw 6 is between the free ends of the two parts forming the member 3 and when in normal position abuts upon the shoulder 5, but leaving an open space wherein the draft appliance from the wagon or vehicle may be received. Then projected above the surface, the jaw 6 forms an acute angle therewith, so that while being carried forward it will pass over the prearranged draft appliance without stopping by turning the rod8 in opposition to the spring 9, attached thereto, the tendency of the spring being to hold the jaw upon the shoulder 5.
The entire mechanism operates within .a conduit 10, comprising two troughshaped piece-s arranged in the ground, as shown in Fig. 5, the upper sides being substantially flush with the street or road surface, and there being a slot 11, through which the catch device may be projected to engage the vehicledraft appliance, the sides of the conduit being braced by transverse projections 10. The chain or cable 1 being endless travels continuously up and down the conduit driven by the propelling wheels or pulleys 2. At suitable intervals along the chain or cable 1 there are rollers 12, or lateral projections may be used, if desired, which ride upon the track-pieces 13, fixed to the sides of the conduit and forming the ascending track. For a descending track two substantially U-shaped members 14 are employed having their bases attached to the sides of the conduit and their sides projectinginward. (See Fig. The rollers 12 or projections, if used, ride upon the upper sides of these track members during descent of the chain or cable. The rods 7 when traveling upward and idle rest upon the chain or cable 1, and thereby uphold the members 3. Said rods 7 preferably carry small rollers 15, which during descent ride upon the lower parts of the track members 14, and thereby uphold the free ends of the members 3 from the base of the conduit. At a suitable point in the conduit are the devices for automatically projecting the members 3 through the slot 11, and said devices consist of the short tracks 16, attached to the sides of the conduit and having their lower endsbentdownward, as shown in Fig. 1, so that the rollers 15 will travel thereupon. Themain parts of the tracks 16 are near enough to the top of the conduit to raise the devices 3 to the position shown in Fig. 2, so that the draft appliance, such as 17, when overlying the conduit will cause the jaw 6 to be raised against the tension of its spring until said jaw passes over and is again drawn down to the shoulder 5. This is the proper connection, and the vehicle will be drawn up the hill, grade, or incline until the parts are disconnected. Within and near the upper terminus of the conduit there is an inclined projection 18, and attached to the rod 7 is a cam 19, which during travel of the chain or cable 1 rubs under said projection, and thereby turns the rod 7 and raises thej aw 6, which, as before stated, is rigid on the rod. On each side of the slot 11 there is an inclined projection 20, against the under edges of which the rod 7 rubs after the jaw 6 has been raised, and this operation draws the part 3 down into the conduit and releases the part 17, and after passing beyond the projections 18 and 20 the jaw 6 will be snapped back to its normal position by the spring 9. The tracks 16 terminate a suitable distance above the lower end of the conduit, so that when the devices 3 are not employed to draw any wagon or vehicle they will after short travel be permitted to resume their idle position in the conduit, and hence form no obstruction above the street or road surface, but disappear below the level thereof only to appear again when commencing another ascent.
In making the connection for drawing the wagon or vehicle up the hill or grade some suitable device connected thereto is disposed across the conduit over the short track 16, so
that the part 3 will automatically engage therewith, as above set out, and the wagon will be drawn steadily upward until released at the top, whereupon the team assumes the burden, from which it had been almost or entirely relieved during the aforesaid operation.
This invention is designed especially for steep hills, grades, and inclines in cities where wagon traflic is great to relieve the necessity of providing additional teams to assist in ascending and toprevent overstrain and overwork of the regular teams employed. It may of course be used in other places, and it forms practically no obstruction or irregularity over the usual street or road surface inasmuch as the catch devices are arranged to disappear entirely below the surface when not in use. The lower end of the conduit may be provided with an outlet, so that the interior may be kept free from foreign mat .ter by flushing from the upper end.
