MEANS FOR CONNECTING DRAFT-TIMBERS AND CENTER SILLS OF CARS.
Specification of Letters Patent.
Patented July 25, 1905.
Application filed April 6, 1905. Serial No. 254,163.
To all whom, it may concern.-
Be it known that we, WVILLIAM HUNTER EM- ERICK and PETER AL UIs'r, citizens of the United States, residing in Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Means for Connecting Draft-Timbers and Center Sills of Cars, of which the following is a specification.
Our invention relates to improvements in means for connecting the draft-timbers and center sills of cars. Heretofore the drafttimbers have been connected to the draft-sills by connecting bolts extending vertically through the draft-timbers and sills and bolting the same together, and great difficulty,
expense, and loss of time have heretofore been experienced when the draft-timbers are broken and require removal and replacement, as it is necessary to unload the car in order to remove the connecting-bolts and remove a broken draft-timber and replace it with a new one.
The object of our invention is to provide a simple, strong, efficient,and durable means for removably connecting the draft-timbers to the center sills of a car, so that the draft-timbers will not be liable to breakage and so that in case a draft-timber is broken it may be removed from a loaded car very easily and quickly and replaced by a new one without unloading the car.
Our invention consists in the means we employ to practically accomplish this object or result-that is to say, it consists, primarily, in the combination, with the center sill of a car, of a removable draft-timber and means for removably connecting the draft-timber to the sill.
It further consists, in connection with the sill and draft-timber, of connecting-plates furnished with dovetails.
It further consists in providing the connecting-plates with a removable dovetail key.
It further consists, in connection with'the sill, draft-timber, and connecting-plates, of a cap-plate and one or more clamp-plates furnished with wedging dovetails to clamp the sills together.
It further consists. in connection with the dovetail connecting-plates, sill, and draft-timber, of a cap-plate and bottom plate and one or more clamp or draw plates furnished with wedging dovetails to clamp the sills-together.
It further consists in the novel construction of parts and devices and .in the novel combinations of parts and devices herein shown or described.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partly in vertical section, of a device embodying our invention. Fig. 2 is a plan view partly in horizontal section. Figs. 3, A, and 5* are vertical sections on lines 3 3, 4 4, and 5 5, respectively, of Fig. 1. detail side elevation of the connection shown in Fig. 3 with the clamp or draw plate removed. Fig. 7 is adetail cross-section through the connecting-plates, showing one form of the same. Fig. 8 is a detail cross-section through the connecting-plates,showing the same furnished with a removable dovetail key; and Fig. 9 is a detail perspective view of the dovetail key. Fig. 10 is a detail partial section on line 10 10 of Fig. 4. Fig. 11 is a detail partial section on line 11 11 of Fig. 3.
In the drawings, A A represent the draft or center sills of a railway-car, and A A the removable drafttimbers; A the front or cross sill; A the buffer-block; B, the coupler; B, the draw-bar; B the draw-bar strap or yoke connected to the draw-bar by rivets b,- B ,'the springs of the draft-rigging; B, the followers, and B the side plates or stop-castings of the draft-rigging, which are attached to the draft-timbers A in the usual manner.
To enable the draft-timbers A to be removed from the sills A quickly and conveniently and without unloading the car and at the same time provide a very strong, efficient, and durable connection between the drafttimbers A and sills A, we provide a plurality of connecting-plates D F, D F, and D F each furnished with interengaging dovetails. The several pairs of connecting-plates I) F, D F, and D F differ somewhat in construction, according to their location in respect to the side plates or stop-castings of the draftrigging, or, in other words, as to-whether they fit along or at the rear or front of the draftrigging. The connecting-plate construction which we prefer to employ at the rear of the draft-rigging comprises, in addition to the connecting-plates D F, having side flanges d d, f f, a cap-plate G, having side flanges g g, and which fits on top of the sill A, a bottom plate H, having side flanges it h, and which fits underneath the draft-timber A, and a pair of clamp-plates K, which are furnished with inclined or wedging dovetails 7c, engaging correspondingly-inclined or wedging dovetails 9 it on the cap-plate G and bottom plate H and preferably on the sides g it of the capplate G and bottom plate H. By this construction the clamp or draw plates K, by reason of the inclined dovetails, operate to clamp the sill A and draft-timber A together in a very firm and strong manner. The rear connecting-plates D F are furnished with transversely-extending dovetails (Z and f 2 on their horizontal meeting faces, which interengage. The rear connecting-plates DT may, if desired, be furnished with a transversely-extending dovetail key M, as illustrated in Fig. 9, in lieu of the construction shown in Fig. 6, the dovetails on both plates D and F being in such case of a female form, necessary to receive such dovetail key M. The clamp-plates K are furnished with slots 76 through which extend a horizontal connectingbolt k furnished with a nut 70* and serving to clamp plates K K together after they are driven home, the slots permitting the necessary longitudinal movement of the clamp or draw plates K for tightening or clamping together the bottom plate and cap-plate and the sill and draft-timber. Vertical bolts N, having heads a, fitting in countersinks g in the capplates Gr, and nuts n, fitting in countersinks d in the sill-connecting plates D, securely fix the connecting-plate D and cap-plate G to the sill and clamp the same together and prevent any longitudinal movement of the plates D F on the sill. Similar bolts N, having heads fitting in corresponding recesses in the drafttimber-connecting plate F, and nuts'fitting in countersinks 71/ in the bottom plate H connect the plates F and H and fix them in position longitudinally on the draft-timber.
The connecting-plates D F, which connect the draft-timbers at points along the draftrigging, are furnished with transversely-extending female dovetails (Z f which receive a transversely-movable dovetail key M, thus firmly and removably securing the connecting-plates D F together. The clamp-plates K, employed in connection with the connect ing-plates D F, are of similar construction to the connectingplates before described, excepting that they are not so wide and do not project over the sides of the draft-timber. These connecting-plates K K, however, overlap the end faces of the transversely-movable key M and prevent its removal until the clamp-plates K are removed.
The connecting-plates D F at the front of the draft-rigging omit the side flanges d d and f f and are furnished with dovetail grooves or female dovetails and are connected byaremovabletransversely-extendingdoubledovetail key M, this form of connecting-plates adapting the upper one D if desired, to be secured to the front'or cross sill of the car and the lower one to be secured to the drafttimbers, although the side plates or stop-castings of the draft-rigging may extend to the front end of the draft-timbers, as is the case in some constructions of draft-rigging.
