BUFFER ATTACHMENT FOR VESTIBULE DIAPHRAGMS.

Application filed January 30, 1924. Serial No. 689,448.

To all whom. it may concern:

Be it known that we, WALTER D. VAUGHAN and EDWARD M. DICKERMAN, citizens of the United States, residing at Rutland, in the county of Rutland and State of Vermont, haveinvented certain new and useful Thi provements in Buffer Attachments for Vestibule Diaphragms, of which the following is a specification.

This invention relates to a buffer attachment, designed primarily for use in connection with diaphragms of ear vestibules, but it is to be understood that a buffer attachment in accordance with this invention can be employed for any purposes for which it is found applicable, and the invention has for its object to provide, 'in a manner as hereinafter set forth, a. bufier attachment to overcome the wedging of the bufier spring so that the diaphragm after contraction will be shifted to normal position, as well as to provide a buffer attachment to overcome the objections presentin the type of buffer attachment now used, and such objections being the wedging out of place of one side of the face plate of the diaphragm, the wedging of one or both ends of the buffer spring, bending of the face plate of the diaphragm out of position, wearing off of the ends of the buffer spring to such an extent that either one or both ends of the spring will break off, wearing out of the connecting brackets for the ends of the buffer springs, and by overcoming such obj ections a buffer attachment is set up which when used will materially reduce the cost of maintenance, as well as providing for a satisfactory buffing action with respect to the diaphragm during the travel of the car, especially when the car is travelling around a curve and further when the cars are not in alignment.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a buffer attachment for the purpose set forth, which is simple in its construction and arrangement, strong, durable, compact, thoroughly efiicient in its use, readily installed, and comparatively inexpensive to set up.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modilications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views 2- Figure 1 is a top lan view showing the adaptation of a bu er attachment, in accordance with this invention, with respect to the diaphragm of a. car vestibule.

Figure 2 is an end view of a car, broken away, showing the adaptation therewith of a bufier attachment in accordance with this invention.

Figure 3 is a top plan view upon an enlarged scale of a buffer attachment in accordance with this invention.

Figure 4 is a section on line 4l-4, F igure 3.

Figure 5 are 3.

Figure 6. is a perspective view of the connecting bracket for connecting the attachis a section on line 5-5, Figment with the body of the car.

Figure '7 is a grouped perspective view of the buffer spring coupling device.

Referring to the drawings in detail, 1 de notes a car body, 2the vestibule diaphragm and 3 the face plate of the diaphragm 2.

A buffer attachment, in accordance with this invention, is interposed between the upper end of the face plate 3 and the car body 1, and the attachment includes a buffer element, a pair of coupling devices and a connecting bracket. The connecting bracket is secured to the car body 1, and one of the coupling devices secures the buffer element to the connecting bracket and the other coupling device secures the buffer element to the face plate 3 of the diaphragm 2.

The buffer element is indicated at 4 and is in the form of an elliptical spring ofthe leaf or laminated type, and said elliptical spring can be of any size satisfactory for the purpose intended. The spring is formed of two like sections of arcuate contour and which are oppositely disposed with respect to each other and pivotally connected together, at their ends as at 5. The connecting bracket consists of a yoke-shaped body portion 6 having each of its arms 7 formed with an outwardly extending right angular- 1y disposed flange 8. The body portion 6 is formed with a series of openings 9 and each of the flanges 8 with an opening 10. The flanges 8 are positioned against the end of the car body, as well as bein fixedly secured therewith by the hold-fast e evices 11, which extend through the openings 10.

One of the coupling devices is indicated generally by the reference character 12, and the other coupling device by the reference character 13. Each of the coupling devices is similar in construction and the description of one will apply to the other.

Each coupling device consists of a rectangular flat plate 14 of substantial width and length and which is formed with a series of openings 15 corresponding in number to the number of openings 9 in the body portion 6. Formed integral with the plate 14, at each side thereof, is a pair of plates 16, 17, which are rectangular in contour and of substantal width. .The plates 16 and 17 are of less length than the plate 14 and each of said plates 16 and 17 is disposed with respect to, the plate 14, so that the latter will project from each of the ends thereof. The plates 16 are arranged in opposed relation or rather in parallelism and are spaced from each other by the plate 14 andare further disposed at right angles with respect to said plate, 14. The coupling device further includes a binder plate 18, having its inner face, as at 19, of areuate curvature, and said plate 18 is furthermore provided with a pair of openings 20 which align with a pair of openings 15 in the plate 14. l Vhen the coupling device is set up, the plate 18 is positioned between the plates 16 and 17 and bears against a. section of the spring 4, in a manner as shown in Flgures 3 and 5. The

inner face ofthe plate 18 conforms to the curvature of that section of the spring agalnst whlch sald face abuts.

Each of the coupllng devlces further in- V eludes two sets of securing members,one set of securing members of each of said couplingdevicesconsists of a pair of headed bolts 21, 22, each carrying a securing nut 23. The other set of securing members which is employed in connection with the coupling de vices 12 consists of a pair of headed bolts 24, 25, of less length than the length of thebolts 21 and 22, and each of the bolts 24, 25 carries a securing nut 26. The other set of securing members employed in connection with the coupling devices 13 consists of a pair of rivets 27, 28, of materially less length than the length of the bolts 21 and 22.

When the coupling devices are set up with respect to the spring 4, they extend towards each other and each coupling devlce overlaps V and is connected to the central portion of a section of the spring 4. The plate 14 of each coupling device is of the samewidth as the width of that leaf of a spring section against which the plate is positioned. The ends of V openings 15 of the plate 14 and further through the inner openings 9 of the body portion 6 of nuts 23 carried by the bolts 21 and 22 abut against the inner face of the body portion 6 of the connecting bracket. The bolts 24 and 25 extend through the outer openings 15 in the plate .14, and also through the outer openings 9 in thebody portion 6, and the nuts 26 carried by the bolts 24, 25 abut against the inner face of the body portion 6 of the connecting bracket.

The coupling device 13 is secured to the face plate 3 and projects rearwardly therefrom, and it is fixedly connected in position by the two sets of. securing members. 7' The bolts 21 and 22 extend through the openings 29, 30 formed in the face plate 3 and the heads are counter-sunk in said openings Thebolts 21, 22, further extend through the inner of the openings 15 of the plate 14, through that section of thespring 4 Which is mounted in the coupling device, then through the openings 20 in the plate 18 and the nuts 23 carried by the bolts 21, 22 abut againstthe outer face of the plate 18. The

rivets 27 and 28 extend through and are counter-sunk in the openings 31, 32,.formed the connecting bracket. The i in the face plate 3, and further are pro i jeeted into and counter-sunk in the outer openings 15 of the plate 14. V V

The foregoing manner of setting up a buffer attachment overcomes the objections heretofore pointed out in connection with buffer attachments nowin general use, and it is thought that the many advantages of the buffer attachment in accordance with this invention can be readily understood from the construction disclosed and illustrated, and althoughthe preferred embodiment of the invention is as shown and described, yet it is'to be understood that changes in the details of the attachment can be had which will fall within the scope of the invention as claimed. w What we claim is 3 1. A buffer attachment for car vestibule diaphragms comprising a connecting bracket adapted to be secured to one end of a car, an elliptical spring formed of a pair of oppositely disposed sections connected together at their ends, a coupling device inclosing and connected to the central portion of a spring section and including means for securing said section to the face plate of the diaphragm, and a coupling device inclosing and connected to the central portion of the other section of the spring and including means for securing said section to said connecting bracket, said coupling devices extending towards each other and each including a binding plate having an arcuate face bearing against the inner face of a spring section.
