CAR-FRAME.

Specification of Letters Patent.

Patented May 1, 1906.

To (1/! whom it may (JOTLOEZTVL:

Be it known that we, WVILLIAM H. EMERICK, residing in Osawatomie, in the county of Hiami, in the State of Kansas, and PETER AL- Uis'r, residing in Memphis, in the county of Shelby, in the State of Tennessee, citizens of the United States, have invented a new and useful Improvement in Car-Frames, of which the following is a specification.

Our invention relates to improvements in car-frames, and more particularly to means for removably connecting draft-timbers or other parts to the center sills and other members of the carframework.

The object of our invention is to provide a simple, strong, efiicient, and durable means for removably connecting the draft-timbers to center sills and body-bolster or other parts of the car-framework.

Our invention consists in the means we employ to practically accomplish this object or resultthat is to say, it consists, in connection with the center sills and body-bolster of a car, of draft-timbers removably connected both to the center sills and body-bolster, so that the draft-timbers may be easily and quickly removed and replaced by new ones when broken without the necessity of unloading the car and whereby at the same time the draft-timbers will be very strongly and firmly anchored and secured in place and connected with both the center sills andbolster.

Our invention further consists, in connection with the center sills, body-bolster, and draft-timbers, of dovetail connecting-plates secured to the draft-timbers and center sills and dovetail connecting-plates secured to the draft-timber and body-bolster, the connecting-plates being furnished with removable dovetail keys which when removed enable the draft-timbers to be readily taken out and replaced.

Our invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a portion of a car-frame embodying our invention. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail vertical section on line 3 3 of Fig. 1. Fig. 4 is an enlarged detail horizontal section on the broken line 4 4 of Fig. 2. larged vertical section on the broken line 5 5 of Fig. 2. Fig. 6 is a cross-section on line 6 6 of Fig. 3, and Fig. 7 is a detail view illustrating a modification in which a metal bolster is employed.

In the drawings, A A represent the draft or center sills of a railway-car, A the front or cross sill, and N the buffer-block.

B B are the removable drafttimbers to which the side plates or stop-castings are secured in the customary manner.

C is the body-bolster of the car body or frame.

To removably connect the draft-timbers B with the center sills A, the draft-timbers are furnished with a series of dovetail connectingplates D, rigidly secured thereto by bolts d,

. and they cooperate with corresponding dovetail connecting-plates D, rigidly and firmly secured to the center sills A and end sill A by bolts (1. The connecting-plates D and D are furnished on their meeting faces with registering dovetail grooves (l to receive a removable double dovetail key F, by which the connecting-plates D D are removably secured together. The connecting-plates D and D are further provided on their meeting faces with registering and interfitting recesses d and bosses or projections d", which serve to additionally lock and secure the connecting-plates against movement in the plane of their meeting faces. The heads (1 of the bolts (1 d fit in suitable countersinks or recesses formed in the connecting-plates D D, so that the heads of the bolts will not interfere with the proper interengagement of the connectingplates. Two bolts are preferably employed for each of the connecting-plates D D, one on each side of the dovetail grooves and key F, and one of the connecting-plates is preferably provided with two bosses or projections cl, one on each side of the dovetail key, the same entering corresponding recesses in the other connecting-plate. The double dovetail removable key F has one dovetail member f fitting in the dovetail groove of one connecting-plate and another dovetail member f fitting in the dovetail groove of the other connectingplate, so that the dovetail key securely locks the connecting-plates together. To look or secure the dovetail key in place, it is provided with a Fig. 5 is an env bolt F, having a head f 2 and nut f and furnished with washers f 4 f projecting over the marginal faces of the key and fitting against or engaging the upright faces of the connecting-plates D D, so that the bolt and its Washers thus lock the key in place while permitginlg its ready removal by first taking out the To removably connect the draft-timbers B" B with the body-bolster C, the draft-timbers B are provided at their rear ends with dovetail connecting-plates G, furnished with flanges or straps g and bolts g for connecting the same to the draft-timbers and which cooperate with corresponding dovetail connectin -plates G, which are secured to the bodybdlster C by bolts 9 extending through extension-flanges g of the plates G. The connecting-plates G G are furnished on their meeting faces with dovetail grooves g g respectively, to receive the removable double dovetail key H, which is held or locked in place by a bolt it, having heads h, nuts if, and washers 72/ By this means we not only removably connect the draft-timbers with the center sills, but also with the body-bolster, and at the same time provide an extremely strong, safe, and reliable connection between the draftetimbers and the car-framework and enable the draft-timbers to be quickly removed and replaced when broken or when desired. While our connecting-plates are specially intended and designed for cooperation with draft-timbers and center sills and body-bolster or other frame members of a car-body, the same may be used for removably connecting other parts and removably securing them together.

In the modification illustrated in Fig. 7 a metal bolster is employed and the connectingplate G is cast integral therewith.
