MOVABLE BULKHEAD FOR 'nnrniennaronrcens.

Specification of Letters Patent.

Patented J an. 9, 1912.

Applicationfiled November '4, 1909. Serial No. 526,222.

Be it known that I, EDWARD Posson, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Movable Bulkheads for Refrigerator-Cars, of which the following is a specification.

My invention relates to movable bulkheads or partitions for refrigerator cars by the use of which ice chambers may be partitioned off from themain part of the car at the ends. The bulkheads may be displaced when desired so as, to make the entire interior space in the car available for freight. The objectof my invention'is to improve the construction of bulkheadsiofthis character in various respects, one of which consists of a series of guideways in the sides of the car which have downwardly turned the bulkhead in either of its positions. Convenient and simple means for raising the bulkhead from the. depressed ends of the guide have been provided, as well as rollers anda track on which it may be easily moved from'one positionto another. v 1 Another object consists of providing means for supporting the grate on which I pivoted to the car. frame.

the-ice is carried and which permits easy whichthe grates are supported at one of heir ends, the otherend of each grate being Another feature comprises stops in the V fioorof the car into which thevertical posts fof the bulkhead frame are lowered.

Other objects and advantages will be apparent in the specification and claims, taken in connection with thedrawings', in whichj Figure 1 is a cross sectionof a'refrige'rator car' body showing a view in elevation with-parts broken awayof one of the bulkheads. Fig. 2 is alongit'udinal vertical section of one end of the car showingthe bulkhead in cross section. Fig. 3 isa horizontal section of one end of the car showing the bulkhead in section and ajportion' of the grates. Fig. e'is a detail showing one of .theupper corners of the bulkhead and tho particularly theshaft and rollers by which adjacent parts of thecar body and showing the bulkhead is. elevated. 'Fig. ;5 is a side view of the same. Fig. 6-is a perspective view of one of the pivoted bails' withpne of the grate bars resting thereon and also one of the retaining hooks for said bail in its proper relative position to said parts. Fig. 7 is a perspectiveview of the lower end ofone of the right-hand members of the bulkhead showing a device for engaging the stops in the perspective view 'of one of the frame members.

floor; Fig. 8 is a perspectlve view ofone of said stops. Fig. 9 1s a In the drawings, the reference numeral 16' designates the outer upright frame memupper ends Near the bottom of the bulkhead is the horizontally disposed Z-bar 20. In the central web 20 of the Z-bar are vrectangular apervtures 20 through. which the vertical posts '17 are placed. The shorter posts 18 .rest at their lower ends upon the web 20 of the Z-barand are fixed to the said Z-bar by" means of the bolts 18 The Z'bar is recessed atits outer end 18 to permit the insertion-of the outer posts 16. In the body of the bulkhead the deflecting devices 20 for the air current are placed between these upright posts and are not described in detail herein because they donot form a part of this invention. The netting 21 is placed against the said posts on their inner faces. The slats 22 are fixed to the front faces of the posts and protect the other deflecting devices 20. A horizontally pivoted door is provided at the-bottom of the bulkhead.

This door comprises slats 23 which are fixed to hangers 24 which in turn are pivoted at 25 to links 26. These links in turn are pivoted to eyes 27 which-are fixed to the"vertical flanges 27 of the Z- bars 20.

The above described bulkhead is'spa'ced a considerable distance from the end wall 28 of the car and in the space thus provided the ice is deposited.

The bulkhead is provided at its upper edge with a horizontal shaft 29 which is pivotally supported thereon by the bearings 30 fixed to the channel bar 19. The shaft 29 is. provided with crank arms 31 preferably integral with said shaft, and in the ice'to rest upon in-th'elower portion'of the I outer extremity of said arms 31 the shaft 33 siderable distance.

is mounted. A roller 32 is fixed'tokthis passes through the lever and has a bearing 1' therein. -The shaft 29 may be rotated by means of this lever andby means of the .eccentrically attached roller 32, above de scribed, the bulkhead may be raised a conhook 36 attached to thebulkhead provides means for retaining the lever 36 in an oper- *ated position in whlch position the bulk-.

head is carried upon the track 34 by the rollers 32. Another hook- 37 provides means for holding the lever 36 in its unoperat'ed positionadjacent the root of the car.

The guides 38 are provided in the walls of the car and serve'to guide the bulkhead between its two positions, one of said posi- I 'tions being that shown in the drawings in which-aspa'ce is separated off for anice chambnthe other of said po'sitions being adjacent the end wall of the car. .These guides have a, channel-shaped cross section of rectangular ,form'in which the ends of pins 41 are made to operate. The ends of the pins 41 areprovided with heads 42 which lie within the retaining flange 43of thelsaid the ends with downwardly extending guides 38. The. guides 38 arefprovided at tions or ofl sets 39. The pins 41 drop 1nto these downwardly extending port-ions 39 in either position of the bulkhead and the bulkhead is thereby securely retained in posi-- tion. In order to move the bulkhead from of the parts related thereto.

v-downwardly extending portions 39 of the one position to the other-lit is necessary to first raise it by means of the lever- 36 as will be clear. from the previous description When thus ra-ised -the bulkhead is free tofslide along the. gu'ide 38 to. the other position. The

guides are provided with the short retaining guard 40 at their lower and inner faces. The guides are securely heldin position in the walls of the car by means of bolts 45,

46, etc;- The.sheetimetal lining 46%"- iscut away around the guides 38 and is made to lapover the upper edges 43 and-to lie within thelower edges 43 0f theguides 38.

-The ice grates 47 are provided for the ice chamber and are pivoted at one edge to the hooks-49 which are bolted to the end wall of thecar. Thespacing thimbles 48 serve as means for making. this pivotal conneo {age by the pressure of the ice;

When thus raisedv its weight is'transferred to the. tracks 34. A

tion. The, said grates 47 are composedof bars which are spaced by thimbles '48.- The grates 47 are given an inclined position'as shown in 'the drawings for the purpose ofcausing-the blocks of ice to move away from the bulkhead and against the end 28 of the car body. By this means the 'bulkhead is protected'in-a' largemeasure against dam- 1 The grates 47 arecomposedpf independentsections which form a-series which liestransversely of the car at the bottom;

of the ice chamber.

The separate ends, of

the grate sections are supported by the swinging bail 51, which is pivoted'at 52 tothe underside of the Z-ba-r 20. The grate bars are-"notched at their ends as shown at 50 a where they rest upon the bail 51.. The down wardly projecting and. outwardly curved 1 8 5 tongue 53 is provided on'each'bail and serves as a means byxwhich the grate bar s may push the :bail' out of'the way momentarily when the grates are being raised to their inclined positions. The grate sections' a r'e adapted to drop into the'pan' 57' at thejbot tions and when the sectionsare lowered their upper surfaces are therefore in the same plane with the floor of the-car; The bail 51 is retained inp'osition below theelevated end'of the grate sections by thehook 54 which is pivoted on one of the spacing thir'n bles 48. It is prevented from dropping down to an excessive degree when not en-v gaged with the bail by anotherof the spac-- ing thimbles. The pan. 57 is provided with a depressed portion 58 and in this depressedv portionis a further depression 58? in which-- is placed the trap 59.. The trap 59 retains a small portion of the water below the level of the end of the outlet pipe 59, thus iseal frhm the outside of the car; r The extended lower ends 61 0f the upright 'frame members 16 and l7.;rest upon,- the"- bottom of the pan57 adjacent-{the inner edge ing the ice chamber against admission- 0f air ire where said pan lies against the floor (SO'otthe car. Near the lowerend ti'l'of the said upright frame meinbersis a :short barf63 which is adapted toengage the 'sto p-'62 in -fl' the floor of the car. .Thisstop 62 is a hollow metal device into which the bar 63proje'cts.

When the bulkhead-is lowered intoxfposi-tion thebar 63 enters the recess in the stop 62. The operation of my. improved bulkhead .has already been largely referred to throughout the preceding'portion of the spee'ificm' tion. I It may be further said that the bulkhead may be very quickly and, conveniently moved from theposition shown in the drawings to a position adjacent th'evendiof the car by first pulling downwardly upon the lever 36, which raises thebulkhead adis tance equal to thedepth of the downwardly" y tom of the -ice chamber. The depth of this pan is equalto the depth of the grate sec'- extending portions 39 of the guides 38. This heads 42 of the pins 41 are free to slide along the guides 38 to'the other extremity of sai guides and when inthe latter position the lever 36 may beallowedto rise to aposition adjacentthe ceiling of the car. By this movement. of the lever 36, the bulkhead is the end wall of the car.

into the downwardly extending portions 39' bails. 51 which are suspended from. the Z-bar permitted to settle into a position adjacent The pins 41 drop of the guides 38 andhold'it in that position.

IThe return movement of the bulkhead to its former. position may of course beefiected in a similar manner. If it is desired to retainthe/bulkhead in a supported position while being moved from one pointto the other without effort on the the lever 36 may on the bulkhead; V V

Both rollers 32 at the endsof the shaft 33 being keyed thereto the later al edgesof the bulkhead are caused to move at the same speed and no attention is required of the operator in causing the bulkhead to move upwardly into position. i

When the bulkhead is used as a partition as abovedescnibed and a-n'ic'e chamber is thereby divided off, the ice may be dropped into said chamber. in the usual way through a hatch in the roof of the can. The ice be engagedby the hook'36" would fall upon the grates??? and the weight of said ice would be carried partly by the 20 and partly by the hooks'49. If it is desired to remove remnantsof ice in the ice chamber before moving the bulkhead to a position adjacent the end of the car, the

grates't'? may bedropped into the pan 57. In doing this the retaining hooks 54 would be first raised after which thebails 51 may be easily swung out from beneath the ends of the grates. i In view of the factthatthe ice grates are.;made in sections it would be clear that one only of these sections may be lowered at a time and the i'ceat any particular part of the ice chamberma be removed. The gate 23 would of course eqraised out of-the way when removing the ice. The link 26 serves an important function when thus raising the gate as it permits the pivot 25 to be swung out of a vertical line below the'pivot- '27., This permit'sthe gate 23 to be fully swung around to a vertical position v against the slats 22 of the bulkhead Thefdownwardly curved tongues 53 on the bails 51 are very convenient for. the operator to seize for the purpose of swinging the bails 51 out of engagement with the ends of the grates 47. 'Their forwardly projecting position causes the handof the operator to be out-of the path of the falling grates They.

upon the floor and part of the operator,

as a partition for dividing otf space as an ice chamber, the lower end 61 of the upright members of the bulkhead frame drop into their proper positions in the forward part of the pan 57, and the bars 63 enter the recess of the'stops 62 without any attention on the part of, the operator.

"The-bottom of the'pan is below the level of the floor 60- and it will be clear thatthe Water in said pan cannot find, its way out cause damageto the contents in the car.

While I have described more or.less precisely the detailsof construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the subst-i-.

tution 'of'equi'valents' as circumstances may suggest or render expedient without depart-- in from the spiritof my invention.
