Be ,it'known that I, HERMAN C- PRIEBE, citizen of the United States, residing. at Blue Island, in the count'y of Cook and State of Illinois, haveinvented a certain new and useful Improvement in- Draft Gears, of which the following is a full, clear, concise, and exactdescription. j I

My inventionrelates to railway cars and to draft gears employed therein.

The invention has for one of its objects the unification of draft gear carriers and draft lugs in. integral structures. 7 This characteristic of my invention has been of par ticularservice in connection with freight cars having wooden center sillsl, In such a car:I employ two angle irons each having an inner upright and a lower outwardly extending side, each angle iron being individual'to and receiving onelof the two center 1 sills of the car at the lower innerlongitudiresisting draft strains.

nal corner of such sill. There are two carriers for each draft gear, these carriers underlying and .beingfa'stened tothe lower sides, of the corresponding ,angle irons. There are also inner and outer draft lugs that-are fastenedto the upright sides ;of the angle irons. "Each angle iron has thus assembled therewith a structure individual thereto and comprising a carrier andinner and outer draft lugs, each carrier and the corresponding draft lugs being formed in one piece. r

, The draft gear carrier portions are desirably inwardly extended'into abutting en-' gagement. with the adjacent body bolster that thus reinforces the inner draft lugs in The invention also relates to those draft gears ,which' employ keys for assembling coupler shanks with the balanceof the draft gears.- In carstructures; having such draft gears th center or draft sills are formed with openings through which the keys are passed in the process of placing them in position. These keys project laterally of the sills and there are cotter pins or other formations to keep them from becoming dis lodged. T j v V In accordance with my invention the draft sills maybe provided with the usual openingsto permit of the passage of keys there- .through. I- am enabled to make these keys sufficiently short; to occupy the space between the adjacent sills without projecting through the sillsg In order to prevent the keys from becomingdislodged the openings in ithe' sills through which they are passed arer sufl i-l ciently covered by obstructions." to prevent the withdrawal of'the'keys. I I willexp'lain my inventionmorefully reference toth'e' accompanying jdrawing'is'flnwl1i'ch-'Fig."-1"is a plan Viewywith parts shown in section andparts broken away, of a portion of a @car structure having equipment of my invention applied thereto; Fig.2 is

Like parts areindicated by similar characters of reference throughout the different figures. v j I v i V I have illustrated -enough of the under frame of a freight car structure to show the relation of my inventionthereto. This underframe includes longitudinal wooden sills 1 and 2 which are cut awayat their outer ends to receive woodenend sills, the end sill 3 at one endof thecar, structure being illustrated. There are two angleirons at each end of the car structure, each angle iron having an inner upright'side 4i and a lower out wardly extending side 5. Each angleiron is :"individual to a'center sill, such sill being received in the angular seat of'jth'e' corresponding angle iron at the lowerinner longitudinal corner of such sill.- Each center sill thus includes'th'ej-wo'oden sill and the angle iron in addition thereto.

There is a-draft gear carrier6 individual to each angleiromeach carrierunderlying and being-fastened to the lower 'side of its angle iron. The means for fastening the carriers to their angle ironsare desirably in the form of rivets 7 which pass through rivet holes 8 inthe carriers and through corresponding rivet holes in the bottom walls of the angle iron.- There are also inner and outer draft lugs 9. and 10- at v each end of the Year structure, each carrier'having an inner lug and an outer lug formed inthe same in v 7 tegral casting therewith. .These, draft lugs are formed with rivet 11 19311, Rivets 12 are passed th-rough these rivet holes and through corresponding rivet holes in the'adjac ent ,upright sidesof the angleirons.

Each carrier has two depressions'1 '13 for re ceiving keys 14 that pertain "to the draft gear. These keys project outwardly beyond the center sills, the outer endsof these keys being surrounded by spring abutments 15 that are provided for the motor resisting Springs 16 upon the exterior of the sills. These keys also pass through followers 17 and 18 thataredisposed between the sills, there'bein'g a longitudinal spring" 19 between and'abutting the followers. A coupler yoke 2O surrounds the followers, this yoke being of U-form, each end of the yoke being bifurcated into fork branches 21. The coupler sills,.being outwardly extended beyond the parts 21.

region of--the key 23 and'having slots 24 formed "therein through which the key 23 may be passed-through the registering slots in the coupler portion 22 and the yoke Hitherto these keys'have projected outwardly beyond the draft sills through which they were passed, but in accordance with my' invention such a key is shortened to be fu'lly confined in thespace between thesedraft sills, the openings 24 being afterwards sufficiently "covered by obstructions 25 to prevent of the repassage of the key therethrough. These obstructions are preferably in the form of angle irons while both draft sills are formed with the openings 2% -which"have to be closed by the ob structions 25, yet it is obvious that but one of these draft sills needs to be provided with such an opening. It will be observed that the obstruction 2'5 lies against the inner upright face of the draft sill to which it. is. applied and substantially to one side of, this face whereby the key receiving opening in this sill may be readily uncovered when it is desired to remove the Each composite draft sillanddraft gear carrier 6 has integrally formed therewith in thesame casting outer and inner draft lugs 9, 10, the outer draft lugs being engaged by the follower 17 and the inner draft lugs being engaged by the follower 18. At. each end of the car-there is a ster and the draft sills co-operate withthe inner.draft lugs in resisting coupler blows.

It isapparentto those skilled in the 'art that the structure of my invention. when employed in connection with car undertrations.
