MEANS FOR SUPPORTING A SEPARATING HOPPER AS APPLIED T0 PORTABLE MILLS Filed Jan. 26, 1931 '10 ered position.

Patented Mar. 7, 1933 'rf-UNITED. 'STA-Tiasl PATENT OFFICE i EARL L. MARTIN, DES MOINES, IOWA v MEANS :Pony SUPPORTING A sEPAnA'rING HOPPER As APPLIED To PonTABLE MILLS Application 1edJanuary'26, 1931.` Serial l1\To..5ll,241.

` l *This invention relates to improvementsA "n j I 5 for adjustably mounting the hopper, whereby the hopper may be easily and quickly elevated and lowered, and at the same time provi-des means whereby the hopper is firmly supported in either an elevated `or low- -More specifically it is the object of my invention to provide an improved support or stand for carrying a separating hopper which is of simple construction and formedv principally of structural steel, and in'such a manner thatthe parts are firmly secured k.together against working loose as the mill is moved fromone position to another.l l

, A further object is to provide improved means for securing the hopper to the movable member of the adjustable support.

A further object is to provide improved means for bracing the hopper after it has been moved to either of its adjusted positions. y Y Y A further object is to provide a simple and strong adjustable stand formed of structural langle iron having a stationary member and a movable 'member Vwith simple and effective means for*l elevating and lowering the movable member.

My invention consists in the construction, arrangement and combinationr of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, andv illustrated in the accompanying drawing, in which:

Figure 1 1 ure 1;

llustrates a'portion of one endv 40of a mill supporting frame vshowing the .Referring to the. accompanying drawing, I have used the reference numeral 10 Vto indicate a supporting frame on which a mill 11 of ordinary construction is mounted. An

enginel 12 is also vmounted on the rframe for supplying powerto the mill. i

Adjacent to oneside of the mill 11 is a blower 13,also'driven from the engine 12,

and designed toV receive material from the.

mill asit lis ground. Said material is delivered to a hopper 14`of ordinarylconstruction. The lower end ofthe hopper is substantially funnelyshaped, while the upper portion .15 of the hopperv'is of cylindical vformation. .A pipe y16 connects the blower 18 with the Vmember 15, in the usual manner, sothat material delivered to' the blower A18 will in turn' be delivered to the hopper 14.

For supporting the hopper 141 have provided an adjustable stand comprising'an upright angle iron 17 having vits lower end welded in one of the corners of the frame 10. One of the flanges 18 of the angle 17 lies adjacent to the inner surface of the side member of the frame, and the otherzflange 19 adjacent to the back member20 of the frame.

` Supported adjacent to the outer surfaces ofthe flanges 18 and 1 9v and near theirv lower ends, and immediately `vabove the frame.

member 10, is a'bar 21, secured in position by welding andV has, its'y ends projecting inwardly, as clearly illustrated in Figure 5.

' The inwardly projecting ends are indicated Vby thenumeral 22.'

Supported near the upper end of the angle 17 is a bar 28 similar to the bar 21, having forwardlyextending portions 24. A crank shaft 25 is rotatively mounted in the members 24, said shaft carrying a sprocket 26.. The forwardly extending'portions 22 have `a shaft`27 designed to support a sprocket wheel 28. Mounted on the

sprockets

26 and 28 is a chain 29, the purposer of which will hereinafterbey made clear.

`The free edges of thefianges 18and19 are provided with strap.l irons 30 welded in position andbent inwardly to form Ahook portions 31. Similar straps. 32 are provided intermediate the upper rand lower endsl of the free "edgesiof said channels,

similar to the members 30. Said hook portions 31 provide guides for a movable angle iron 33 mounted inside of the angle 17 in the manner clearly illustrated in Figure 3. The outer surfaces of the flanges 34 of the angles 33 are provided withl blocks 35, to serve as spacers to permit the outer lcorners of theiangle 33 from engaging the liilet of the angle 17.

By this arrangement it will be seen that the angle 33 is free to slide upwardly 'and downwardly in the angle 17. The angle 33 -is connectedtothe inner run of the chain 29 by means of a block 3d in such a manner that as the chain 29 is rotated, the angle 33 will be moved upwardly and downwardly. -The outer run of thechain 29 is provided with a stop memberl 37 designed toeiigage the sprocketl 28v when the angle 33 has reached itsupper limit of movement. The angle'33 is locked against downward movement by means Aof suitable set screws 33 mounted in the

flanges

18 and 19. The crank shaft 25 is provided with a crank 39 for operating the chain 29.

lA brace bar 40 is welded to one side of the flange 19 near its upper end, and has its lower end connected. to one of the frame members 10. A similar brace bar-l 41 is secured to the outer surface of the angle 13 land to the frame member 20. Said brace 'bars `support the angle 17 in an upright position, and also the flanges A13 and 19 against 'torsional movement about the longitudinal' axis of the angle.

Secured to the upperend of the flange 33 is abracket plate 42 having rearwardly and outwardly lextending `portions 43. Bands 44l are pro-vided for the upperand lower ends of the member A15, the ends of said bands being secured together by means of a bolt v45 projecting through suitable lugs 46.

Mounted between the inner vedges of the bands 44V Lis a plate 47 welded or otherwise rigidly supported between the inner 'edges of said bands. rllhe plate 47 and the bands 44vare secured to the members 43 by welding, :so that the bracket 42 the plate 47, and the bands 44 form a unit-ary frame member for clamping the upper end of the hopper 14, and providemeans whereby the hopper may be easily and quicklyl removed if so desired for repairs or the like, lby simply loosening the bolts 45, permitting` the 'ends of the bands 44 to be separated sufiiciently to allow Ithe hopper tov be removed.

`The bands 44, the plate 47 and the bracket '42 provide means for rigidly supporting the hopper to the upper end of the .movable supporting member 33. Y

To assist in supporting the weight of the hopper and to assist in preventing swinging of the hopper about the longitudinal axis of the member 33, l have provided a telescoping brace member48, one end of which is pivotally connected to one of the frame members 10, and the opposite end pivotally connected to the lower band 44. A. pin 49 is provided for locking the movable members of the brace in its various extended positions. Suitable openings 5() are provided in the brace members for the pin 49.

By this arrangement it will be seen that I have provided a support for separating hoppers, especially designed to be used in connection with'portable mills, and formed principally of structural steel having all of its fixed membersrigidly supported together by welding, to prevent loosening of the connections between the members due to excessive vibiations as the machine is moved from one position to-another over rough ground.

Furthermore, l have Vprovided means whereby the hopper may be easily and quickly adjusted toV 'various' elevations vas desired in the operation of the machine, and

`provided with an adjustable brace for rigidly supporting the hopper in said adjusted positions.

.I claim as my invention:

1. The combination of an upright support, a second upright support slidably mounted longitudinally of the first support, a supportingf'rame comprising a pair of parallel annular lframe members, and a plateadjoinling a portion of the inner edges of said frame, and means for locking the movablerv members of said brace to each other and in one of a number of adjusted positions.

3. The combination of, a rectangular frame, an angle iron supported vertically from one corner of said frame, a brace. mei'nber connected to the outer lsurface of each flange of said angle near its upper end, one of said braces being connectedto one of the side members of said frame and the other to one ofthe end members of said frame, a second angle slidablymounted longitudinally of the first angle, guides carried by the first -iio angle for slidably supporting the second angle, a laterally. projecting supporting to the corresponding side member of said i supporting bracket to prevent swinging movement of saidvsupporting frame about the longitudinal axis of said supports.
