BUGGY-BOW SPRING ATTACHMENT.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed July 12, 1905. Serial No. 269,376-

To all whom it may concern:

Be it known that I, GEORGE A. Jonxsox, a citizen of the United States, residing at Clyde, in the county of Callahan and State of Texas, have invented new and useful Improvements in Buggy-Bow, Spring Attachments, of which the following is a specification.

This invention relates to a cushioning attachment or spring device for application to buggy-bows to prevent bending and breaking the latter and to materially relieve a buggy of injurious vibrations due to a sudden fall of a buggy-top.

The present improvement consists of an elongated spring of suitable proportions and formed with a central depression or curvature to take up the major part of the shock when contacting with the usual stop projecting outwardly from therail and serving as a fulcrum supporting means for part of the bow structure. This spring has a sleeve with an interior buffer of such dimensions as to freely slide over the bow member to which it is applied and at its lower extremity is ful crumed on a special form of bracket which is clamped to the rail.

In the application of the improved attachment to a buggy-bow no special construction of the parts of the bow and the rail is necessary, and the formations of openings or weakening structures with respect to the rail are avoided.

In the drawings, Figure 1 is a side elevation of a buggy-top, showing the improved cushioning or spring attachment applied thereto. Fig. 2 is a longitudinal vertical section through a portion of the upper extremity of the spring and the sleeve connected thereto. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 1, and taken longitudinally through the connecting-bracket for the lower end of the spring. Fig. 4 is a detail perspective view of the bracket for securing the lower end of the spring to the rail.

Similar numerals of reference indicate corresponding parts throughout the several views.

The numeral 1 designates a side railusually forming a part of a buggy or carriage seat structure and provided with an outwardlyprojecting stop 2 at the rear. The bows are connected, as usual, to the forward upturned extremity of the rail 1, and to the rearmost bow 3 on one or both sides, preferably both sides, the improved spring attachment is applied. This spring attachment consists of an elongated band-spring 4, of suitable thickness, having an intermediate bend 5 to strike against the stop 2, as in usual devices of this class.

Secured to the upper end of the spring 4 is a sleeve 6, having such interior diameter as to readily slide or move longitudinally over the rear bow. This sleeve is riveted or otherwise secured to the upper end of the spring, and has a buffer or gasket 7 therein, which is held in place by the securing-rivet for the spring and also by a diametrically opposite rivet 8. The advantage of the sleeve 6 is that the fact that the spring is applied to the bow separation thereof from the latter will be impossible and the attachment will always be in position for operation. The enlarged diameter of the sleeve with respect to the bow with which it engages also obviates injury to said bow, especially in view of the buffer or gasket 7, located in the sleeve.

The lower end of the spring 4 is firmly se cured to a clip 9, having a knuckle or loop 10 at its lower end, which is fitted over and free to turn on the shank of an eyebolt 11 and held in place by a nut 12, engaging the outer extremity of said shank. The eye of the said bolt 11 is disposed under the lower aw 13 of a clamp let, a bolt 15 being inserted through an upper jaw 16, the lower jaw 13 of the clamp, and the eye of the bolt 11 and held against movement by a lower nut 17, which also serves to draw the jaws of the clamp together.

The clamp 14 is fitted over the rail 1, and the latter, as in the ordinary devices of this class, is elliptical in cross-section. The open ing through the clamp which engages the rail is also approximately elliptical, as at 18, and when the clamp is applied the elliptical contour of the rail and the opening 18 of the clamp will prevent movement of the latter.

From the foregoing it will be observed that the application of the attachment to the buggy bow and rail is simple and facilitated by the use of the clamp structure including the eyebolt set forth and that the clamp will always be held in one position after application. Another advantage of the use of this clamp is that it can be moved longitudinally to any point desired on the rail, either toward the front extremity of the latter or rearwardly, and by such means increase or decrease the resilient resistance of the spring 4 in accordance with the weight of the buggytop as an entirety. In pursuing this adjustment longitudinally of the rail the sleeve 6 will readily accommodate itself to the change The improved attachment may be quickly applied to any buggy-top now in use as well as to like structures on carriages, wagons, or other vehicles.

Having thus described the invention, what is claimed as new is 1. The combination with a buggy bow and rail having a stop, of a yielding attachment consisting of an elongated spring having a sleeve at the upper extremity thereof loosely embracing'the bow, and a clamp adjustably mounted on the rail and having the lower end of the spring fulcrumed on a portion thereof.

2. The combination with a bow and rail having a stop at the rear extremity thereof, of a yielding attachment consisting of an elongated spring having a sleeve at its upper extremity loosely embracing the bow and provided with an inner buffer, and a clamp readi 'ly applicable to and removable from the rail and having the lower end of the spring movablyconnected to a portion thereof.

3. The combination with a bow and rail having a stop at the rear portion thereof, of an elongated spring having means slidably engaging the bow, and a clamp secured on the rail and having an eyebolt projecting out wardly therefrom, the lower end of the spring being movably attached to the shank of the eyebolt.

4. The combination with a bow and rail having a stop at the rear portion thereof, of an elongated spring having means at the upper end for loosely engaging the bow, and a clamp secured on the rail and having an outward projection to Which the lower end of the spring is movably connected.

5. The combination with a bow and arail having a stop at the rear portion thereof, of an elongated spring having means at its upper end loosely embracing the bow, a clamp fitted over the rail and provided with outwardly-projecting jaws, an eyebolt disposed against the under jaw, and means for connecting the clamp-jaws and the eyebolt, the lower end of the spring being movably at tached to the shank of the eyebolt.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
