To all whom 'it ymail] concern: l

Be 'it known that I, CLARENCE H. Howsiu), a citizen lof the United "States, residing at St. Louis, in the State 'oi Missouri, 'here 'invented a. neviT and useful 11n rovement in Cor-Underemes, oij .which tlie following is a specifoa'tion.

` Vy invention relates to :i oost motel cer underfra y, e porticnlztry adapted for e. seli oiearingv'ore, o1 anoiogous duinpeesr havingside hinged drop-doors, and has for its object to provide sst'ong, rigid, :ind durable under which the metal surrounding 'the discliorge o enings therethrough 'is disposed 'to the rest advantage for resisting the lateral stress or spread of the load thereat.

The invention consists in features oi noveity ss hereinafter deseri'bed and claimed, reference being lied to the socomi'isnying drawing 'forming port 'oi this speciiieeti'on, Wirereon, y

Vertical transverse section to enizirved seele through the underframe and our' )ody on line 3, 3, in Fig. 2, showing the side hinged drop-doors, end Fig. 4, s. side elevation of the middle portion of the: underrelne and eer body' (broken away) 'et endudjaeent to the said doors.

gitudiuol channel members l iuii-u'medieto to the side meinhers "l, one on euch sido oi the longitudinal center oi the uniler'friuue o., :uid unitingr the transverse n'ieiubers 2 und I3 together, and s, middle'longitudinal prei'eruhijr -sheped member 5 uniting the transverse, 'i'nenibers 3 together ond iorniing therewith the openings c through the undertreuie a, for

receiving the lower Aportion oi the hopper (l 4of the om' body es hereinafter more'particularly referred to. Euch side member i is 'united lzitei'elly to the middle lonfitudiiml member o by two opposite transverse ixioinV- hers 6, one on each side of the couter of the undorirane a, esuli member (i lining prof-,tienlly Z-shsped, or other-'wiso adapted in cross'section, to reeeive the bottom odge portion of the eorresiwnding iii-.dined end well i, oi' the hopper d :uid forming therent u. rigid brztce to the longitudinal members i :md 5 for resistingT the ietorel or spreading ru'issuro of the materiel within the hopper d.

The lbottom oi the hopper nl lonoitudinelly in tire middie by' V- imperi flooring' 8 which is arranged -di rcctly over :ind along the middie longitudinal member 5, and united et its ends to the inclined end walls 7 of the hopper d, the iuclined side wells of the ilooringr 8 being fixed to and rs'upported by intermediate eorre-- s'pondingly shapedv breekets 9 secured to the top of the' middle member 5 o t suitable intervtileniong the saine, by bolts 10, or in any otiiei'suitsble manner. Within the inn verted' V-sheped s )ece thus formed between the ilooring 8 and t 1e top of the middle member 5 is mounted the longitudinsl shaft 11 with its bearings 12 sind drum i3 for the chains 14 (whereby the drop-doors e are operated), which being of the ordinary well- 'known construction and forming no part of my invention need no further description.

For permitting free movement of the' chains 141- over the outer lateral edge por* tions of the middle member 51, "I foi.'1n"`jtlie latter thereet with recesses 15 having round* ed feces 15 for engagement by the chains 14, which are thereby )revented from chefing and undue weer, anni the opening und closing oi the doors e facilitated. The drop-doors e for closing the openings 16 which ore formed, respeetiveiy, through. the bottom ofthe hop,m per d on cseiiz side of the middle memiier between tile letter und the opposite portion oi the side member 1 end the corresponding transverse members d, ere preiernioly hinged iiof to the underside of the side members 1, theV lugs or iixed portions'' te Which noch door is 'pivoted by pins 18, being integral' with the corresponding side member 1 as shown.

ln the above construction, by uniting the L ends of the transverse members 6 to the side and middle longitudinelmembers 1 and 5, l

and thereby forming solid sill frames around the outlet openings 16 of the hopper d', the rigidityr and resistance to spree-ding of the underirame a thereet .ere greotl increased end positive uniform closing o the dropdoors e insured at ell times. `It is here noted that in Fig. 3 one of the drop-doors e is shown its open position for the purpesefoi' clem-ly indicating the configuration of the transverse members 6 at their bottom edges a ainst which the doors e bein` when closed athough in practice both doors a are opened to form the body-holsters of the car, a middle lo'ngitudimtl member uniting the said tran.:-

verse members together, and two opposite transverse members integral with and uniting the middle member to erich side member end edepted therewith to support thecorres ending part of the lower end of s hopper en yto form the walls of on outlet opening from the said hopper through the said frame,

substantially as described.

t t x I i i l l i l i 2. in rt car underirenn ol' the ehsrertcr described, the combination oi' the side members, the end sills, transverse members uniting the side members together and adapted for the application thereto of suitable drelt` gear, e. middle longitudinal member uniting the seid transverse memliiers together, und two opposite transverse members integral with and uniting the middle member to euch side member und adopted therewith to support the corresponding part of the lower end of n hopper and to form the Walls of on outlet opening from the said hopper through the said frame, substantially es described.

3. ln a cnr uuderl'rmne ol the character described, the combination of the side moxnbers, transverse members unitinsor the side p members together, n middle longitudinatl number uniting the said 'transverse members f together, and Atwo opposite transverse members integrnl'with und uniting` the middle member to eachsidc member und adopted therewith to support the corres )onding port of the lower end ol' a hopper' im( to form the wells of an outlet opening from the seid hopper through the said treme, substantially ns described.

4. ln :t cnr underl'rame of the character described, lugs integral with e side member ol the said frame and adapted for hinging the drop-door of o hopper thereto, substantially as described.
