DRAFT-RIGGING.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed July 13, 1914. Serial No. 850,695.

To all whom it may concern."

Be it known that I, PERRY BROWN, a citizen of the United States of America, and a resident of Coraopolis, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Draft-Riggings, of which the following is a specification.

This invention relates to improvements in draft riggings of that character in which followers are arranged between a pair of side bars located between the intermediate sills of a car, springs or other cushioning devices being located between the followers to absorb the blows.

The invention consists in the construc-' tion and arrangement of parts hereinafter more fully described and set forth in the appended claims.

In the drawings accompanying and forming part hereof:

Figure 1 is a top plan view, with parts in section, of a draft rigging showing the preferable embodiment of my invention;

Fig. 2 is a longitudinal vertical section of the same;

Fig. 3 is a vertical central section taken on a line going through the springs;

Fig. 4 is a perspective view of one of the side bars detached;

Fig. 5 is a perspective view of the rear follower detached;

Fig. 6 is a perspective view of one of the intermediate sills, the front follower and part of one of the side bars;

Fig. 7 is a longitudinal section of a modified form;

Figs. 8 and 9 are details of the modified form;

Fig. 10 is a perspective view of the bottom of a modified form of rear follower.

Referring now to the details of the drawings by numerals: 1 designates the ordinary end sill of a car and 2 and 3 the intermediate sills. The ordinary coupler or draw bar has its shank 4 passing through the end sills and between the intermediate sills, in the usual way, the said shank being supported by a carry-iron as 6 in Figs. 1 and 2. The longitudinal sills are slotted slightly at the rear of the end sill, as indicated at 8 and 10. In the form shown in Figs. 1 and 2 a horizontal supporting bar 12 is employed which passes through the slots 8 and 10 of the intermediate sills 2 and 3 and also through a slot 14 in the shank 4 of the draw bar. As will be seen in Fig. 1, the horizontal supporting bar 12 snugly fits the opening 14 in the draw bar shank but has play in each direction in the long slots 8 and 10 of the intermediate sills. Located between the intermediate sills, and just behind the draw bar shank is a front follower 16 between which and the rear follower 18 are interposed the usual springs 20. These followers 16 and 18 are chambered as illustrated in Fig. 2 to receive the aforesaid springs 18 and the space between the chambered walls of the followers 16 and 18 is such that these walls will come together to prevent the springs from being crowded beyond their capacity. As illustrated in Fig. 2, the springs are of difierent lengths, the lighter springs being longer than the heavier springs so as to take up the lighter shocks and give increased travel while after a slight movement of the follower both springs come into play to absorb the heavier shocks. The rear follower abuts against a pair of heavy castings 24 and 26 which are riveted to the intermediate sills 2 and 3 and have bolts 30 passing through them, the bolts also passing clear through the intermediate sills 2 and 3 so as to prevent any spreading of said sills. these castings 24 and 26 are hollowed out as shown at 32 and 34 as indicated in Fig. 1 for a purpose to be explained. Each of the followers 16 and 18 is formed of the shape shown in Fig. 5, that is to say, each follower has a pair of lugs 40 at the upper end and a pair of lugs 42 at their lower ends, the lugs 42 of the rear follower being extended rearwardly as shown at 46 in F ig. 5. The lugs 40 and 42 of the followers are designed to straddle or extend over a pair of side bars 50 and 52 which are generally of the shape shown in the perspective view in Fig 4. As there shown, the front end of each side bar is provided with a slot 54 with reinforced walls through which passes the horizontal bar 12 hereinbefore referred to as passing through the opening 14 of the shank of the draw bar. The rear end of each side bar is provided with a hook shaped end designated 56. This hook shaped end may be of any desired shape, but I prefer that shown in the drawings. The rear sides of these hook shaped ends 56 are designed to fit into the recesses 32 and 34 hereinbefore referred to as being formed in the front ends of the castings 24 and 26 and the hooks are de- The front ends of signed to hook into recesses 60 (see Fig. 5) formed in the rear follower 18. This hooked end serves the double purpose 'of' drawing the rear follower forward on a pull and 5 also of preventing the side bars from' being spread apart and it follows that if the bars 50 anc1'52 cannot spread the tendency of the sills to spread is greatly overcome. I have hereinbefore described the rear follower as having projections 16. These'are for the purpose of supporting the rigging in its proper position, as theprojections 4L6 are designed to rest upon a carry-iron 62, illustrated in Figs. 2 and 4. Or, instead of having'the projections 16, the rear follower may be provided with a buttressed flange 63 (Fig. which would rest upon the carry-iron 62- Any kind of cheek plate or abutments may be used on the inner faces of the intermediate sills 2 and 3, but I prefer toemploy an' arrangement like that shown in the drawings comprising a casting designated by the numerals 643 This casting extends from the pointdesignated 65 in Figs. 1 and 6 clear up to the end sill and its-front is flanged as at 66 and riveted to both the end sill and to the intermediate sill. In the form shown in Figs. 1, 2 and 6, this abutment casting is-slotted as indicated at 67 for the movement of the horizontal bar-12.

The side bars also have lugs 53 which are normally the same distance from the abutment 65 asthere is space between the followers, so that said lugs will contact at 65 at the same moment the springs are compressed to their capacity. Lugs 55 are also formed on the rear ends' of the bars to'*con'- tact with the castings 2% and 26.

In the modified form shown in Figs. 7, 8 and 9, -I omit the slots 8 and 10 in the intermediate sills2'and 3, and employ only slots 70 formed in'the abutment castings 62. These-abutment castings are formed with openings 7 2 which enter the slots 70, andthe horizontal bar 7% instead of being long enough to pass through the intermediate sills as' at 12 in Fig. 1, is only long enough to bridge the space between the intermediate sills. In assembling-the parts-of them odi fied form, the rigging is first placed in'position and then the draw bar with the horizontal bar 66 passing through its shank is inserted upward from beneath the car through the opening 7 2 of the abutment castings when the'carry-iron is placed under the shank of the draw bar in order to support the same. lVhen this carry-iron is in-position the horizontal bar 7 1 will be in the position shown in Figs. 8 and 9 so that it may be moved either forwardly or rearwardly within the slot 70 the rear end of the rigging being supported by the lugs 46 projecting from the rear follower overthe 65 carry-iron 62 as hereinbefore described.

In operation, whether in the preferred form or in the modified form, upon an impact, the"draw'bar shoves the front follower 16 to the rear compressing the springs be- I tween the two followers 16 and 18, the thrust being received by the rear follower abutting against the heavy castings 24 and 26. On a pull, the draw bar shank pulling upon the horizontal bar 12, in the preferred form or the bar 74 of the modifiedform, draw the side bars 50and' 52 forwardly'and as the rear ends bf'these'side bar's arehooked into the rear follower, said rear follower is also drawn forward to compress the springs between it and the front follower'16, the front follower being held from'fo'rward movement by means of the rear ends 65 of the abutment casting 63.

Fronrthe foregoing and the accompanying drawings, it will be seenthat I have invented'a draft rigging-in which the intermediate"sills' "are securely connected 'to-" gether by means of'the heavy castings, 2i and 26 and the bolts 3O,s 0 as'to prevent spreading of the sills, but the side bars 50 and-'52 are provided with projections which enterrecesses in" the castings2et and 26 secured to the intermediate sil'l's so th'at'upon an impact these parts willalso tend to prevent any spreading of the sills. Furthermore, as the side bars are provided with members as the hooks 56 'to jco-act the rear sides of the rear followers, it, willbe I noticed that these rear followers do not need any separate. connection as for example, a horizontal bar, bolts or equivalent means, to connect the rear follower with said "side It will be obvious that modifications bemade without departing from the spirit ofmy invention, the scope of which set forth in the appendedtlainis'; V

What Iclaimas'my invention is:

1. In draft rigging and in combination with thesills and draw bar, a pair of side bars, front and rear followers, and a cast ing' secured to the sills and receiving the blow from said rear follower,said side bars and saidcasting having 'coniplemental projections and recesses co acting to prevent spreading upon an iinpactW 2. In draft rigging and combination with the sills and drawbar, a pair of side bars, front and rearfollowers, a pair of cast ings secured to said sills and having'recesses therein, said side bars}liaving projections fitting in said recesses upon an impact and thereby preventing spreading.

3 In draft rigging and in combination bolt passing through said castings and through said sills.

4. In draft rigging and in combination with the sills and draw bar, a pair of side bars connected with said draw bar, front and rear followers each having lugs projecting over and under said side bars, abutments on the sills co-acting with the lugs projecting from said followers, the rear ends of said side bars having hooks co-acting with the rear follower, said rear follower having a horizontally projecting member and a carry-iron connected with the sills and supporting said horizontally projecting memher.

5. In draft rigging and in combination bar located to contact with the abutment when the followers abut against each other under outward movement or draft on the draw bar.

In testimony whereof I afiix my signature in presence of two witnesses.
