Specification of Letters Patent.

CAR-UNDERFRAME.

Application filed November 30, 1914. i Serial No. 874,681.

To all 007mm it may concern.' j

Be it known that I, RICHARD I/Vnn BUR- Nnr'r, a citizen of the United States, residing at Montreal, in the Province of Quebec and Dominion 0f Canada, have invented a certain new and useful Improvement in Car- Underframes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in car under frames.

An object of the invention is to provide an under frame structure for cars having wooden center sills and which is particularly adapted for repairs.

Another object of the invention is to provide a construction suitable for repairing carsrhaving wooden center sills and which is adapted to have attached thereto stop castings of the type generally employed with.

wooden draft sills.

In the drawing forming a part of this specification, Figure 1 is a longitudinal vertical sectional view of an end portion of a car taken along the longitudinal center thereof. Fig. 2 is a horizontal sectional view, the lower half of which is taken substantially on the section line 2 2 of Fig. 1 and the upper half on the section line 2A 2A of Fig.

. 1, said Fig. 2 showing a draft 'ear applied,

the parts vof the latter being s own in top plan view. Figs. 3 and 4 are enlarged detail sectional views taken respectively on the lines 3 3 and 4 4 of Fig. 1. Fig. 5 is a sectional view, similar to Fig." 3, showing another form of my invention. Fig. 6 is a view, similar to Fig. 1, showing another form of my improvements, and Fig. 7 is a horizontal sectional view taken substantially on the line 7 7 of Fig. 6 and showing also a tandem spring draft rigging in position, the parts of the latter being shown in top plan view.

lReferring now to Figs. 1 to 4 inclusive, 1.0 10 denote wooden center sills, 11 an end sill, '12 a buferor dead block and 13 a body bolster. Secured tothe' inner faces of each of the centerl sills 10, is a plate 14, each of which has an upper vertical portion 15, lower vertical portion 16, the latter being ,offset from the upper portion 15 by means of a horizontal web 17 which lits against the under face of the sill. The portions 15 are secured to the sills 10 by transversely extend- Patentea Apr. 15, 1919. y

ing bolts 18 which, at their outer ends, pass through plates 19 on the outerV sides of the sills. As shown in Figs. 1 and 2, the portions 15 are provided with inturned flanges 20 at their front ends which abut the rear face of the end sill 11 and are secured thereto Vby bolts 2l. vThe portions 15 are also notched or cut away as indicated at 22, to pass by the body bolster 13. Secured tothe outer face of each of the depending portions 16 are upper and lower angles 23 and 24 which brace and strengthen the plates 14. As will be understood, the angle irons 23 and 24 are suitably offset as indicated at 25 25 in Fig. 1 at the free ends thereof to conform to the narrowed width of the portions 16 where the same extend beneath the end sill and buffer block. The horizontal flanges of the upper angle irons 23 are secured to the sills 1() by vertical sill bolts 26. To further strengthen the plates 14 and also to assist in absorbing the bufling shocks, I provide a U-shaped plate having side arms 27 riveted to theportions 16 and a transversely extending portion 28 which abuts the front side of the body b olster 13. The depending portions 16 of the plate 14 serve as draft sills or draft members for the stop or side castings 29-29, having mounted therebetween a draft gear which, as shown, is of the tandem variety and comprises followers 30, springs 31, yoke 32 and `draw bar 33.

. In the construction shown in Fig. 5, the plates 114 have the upper portions 1157bolted to the outer sides ofthe center sills, the transversely extending securing bolts 118 therefor vpassing through wear plates 119 on the inner sides of the sills. In this'construction, the vvertical sill bolts 126 pass. through the vhorizontal webs 117 of the plates instead of throughan upper angle iron in the construc- ,tion shown `in the rstlfour figures. In other respects, the structure shown in Fig. 5 corresponds to that shown in Figs. 1, 2 and 4.

In Figs. 6 and 7, theconstruction is similar tokthat shown-in the first four figures, except that the plates v214 are provided with offsets or indentations 40 40 inwhich are Ladapted to vbe seated the lugs 41`formed on the back faces of the stop castings 229, which lugs 41 are those ordinarily found on stop castings which are employed with wooden draft sills and are seated in notches cut in the wooden draft sills. With'this construction, in repairing a car having wooden draft sills, my improved plates 21a are substituted therefor, the'sanie having means provided for re-attaching the stop castings used with the wooden draft sills. In the construction shownv in Figs. 6 and 7 the angle irons which brace the draft member portions of the plates 214; are also offset as indicated at 42-42 where the angle irons pass by the offsets 40 in the members 214.

From an inspection of Figs. 3, 4 and 5, it 'will be seen that the plates 14e and ll/l, which may be said to be of Z-sliape, in combination with the plates 19 and 119 form a box-like casing for the wooden center sills, which I have found to be of great practical value in repairing cars, especially when the sills have 'been split from any cause. lVith my arrangement it becomes unnecessary to remove or replace such split sills, since the application of the inner and outer and bottom plates thereto, when tightly bolted, form a rigid and strong casing therefor.

Y I claim l. In an underframing for cars, the combination withwooden center sills, end sill, and body bolster, of platessecured to the inner sides of said center sills and having oiset depending` portions disposed beneath said sills, the offsetdepending portions being connected to the upper portions by integral horizontal webs, separate plates secured to the outer faces of said sills, angle irons secured lo the outer upper portions of said offset portions ofthe first named plates, said angle irons engaging the under sides of said sills, horizontal ybolts extending through said plates on theV sides of said sills, and vertical bolts extending through said angle irons and said sills, whereby the center sills are provided with a substantially boXlike casing.

2. In an under-'frame for railway cars, the combination with wooden center sills, end sill, and body bolster, of'plates secured to the inner faces of said center sills, each of said plates extending from the end sill toa point in the rear of the bolster and provided with a depending offset portion disposed beneath the sill, said depending portion serving as a draft sill, upper and lower angle irons secured to the outer faces of said depending portions of the plates, the upper ones of said yangle irons being bolted to the center sills.

3. In an underframe construction for cars, the combination with a wooden center sill, of a plate secured to one sideof said sill, saidplate having a depending portion'below the sill to which is adapted to'be attached a stop casting, a reinforcing member secured to the depending -portion .of said plate and abutting the bottom face of said sill, another plate secured to the opposite face of saidvsill, horizontal bolts extending throughfsaid plates on the sides of said sill and vertical bolts extending through the reinforcing member and-said sill, whereby the Y sill, the draft plate having an outwardly l turned web reinforcing its bottom edge, cheek plates on the depending portions of the draft plates, secured thereto, and means for securing the cheek plates to the inner faces of the depending portions of the draft plates in the forni of two rows of rivets, the upper row passing through the vertical web of the angle, the draft plate and the cheek ilate.

l 5. A reinforced wooden underframe for cars having wooden center sills, draft plates secured to the inner faces of the center sills, aporti'on of the draft plates extending below the sills and offset outwardly, horizontalangle irons secured to the upper and lower edges of the depending portions of the draft plates, each upper angle iron having one flange securedto the bottom face of one sill and a vertical ange secured to the depending portion of f the corresponding draft plate justbelow the sill, the other angle iron having' a horizontal flange at the bottom of the draft platey and a vertical flange secured to the lower portion of the draft plate, and cheek plates secured tothe depending portions of the draft plates, and l means passing through the vertical webs of the angle irons, the dependingportion of the draft plate and the cheek plates for holding the parts together.

6. As an article of manufacture, a draft arm and center sill reinforcement constructed to be used with cars having wooden center sills, said article comprising draft plates adapted to be secured to the inner faces of the sills and having an outwardly offset portion, a portion of each draft plate depending from the offset portion, horizon-V tal angle irons leach having one flange .adapted to be secured to the bottom face of one sill, the other flange of each angle iron being secured to the depending portion of the corresponding draft plate, the draft plate4 `having an outwardly turned web reinforcing its bottom edge, cheek plates on the depending portions of the draft plates, secured thereto, and means for securing the cheek plates to the inner faces of the depending portions of the draft plates in the roo ias

form of two rows of rivets, the upper row passing through the vertical web of the angle, the draft plate and the cheek plate.

7. In a car underframe reinforcement, the combination with stop castings provided on the outer faces thereof with projecting lugs, 0f wooden center sills, metal draft plates secured to the faces of said wooden center sills and extending between the end sill and the car bolster, said metal draft plates having portions depending below the wooden center sills and offset beneath the latter, said depending portions of the draft plates being provided on their adjacent faces with recesses within which are received the projecting lugs of the stop castings.

8. In an underframe construction for cars, the combination with a wooden center sill, of a rolled plate secured to one side of said sill and provided with a depending portion beneath the bottom of said sill, said depending portion being offset from the upper portion and the plate extending c0ntinuously from the end sill of the car to a point at the rear of the body bolster, said depending portion of the plate being provided along the lower edge thereof on the outer side with a reinforcing flange, said depending portion of the plate being also r0- vided with outwardly extending o sets adapted to receive the usual lugs formed on the outer sides ofthe draft rigging stop castings employed with wooden draft sills.
