Filed: 1938-09-20
Abstract: 502,334. Vehicle bodies. DA1MLERBENZ AKT.-GES. Sept. 20, 1938, No. 27419. Convention date, Sept. 21, 1937. [Class 108 (i)] The invention is particularly concerned with stream-lined bodies as used on sports or racing oars, wherein the body is carried by a supporting structure and is characterized in that the external skin m, Fig. 3, is produced independently of the supporting structure g, h, i and is applied as a whole to such structure. The skin can be made from a single sheet or parts welded, hammered or pressed together to obtain a smooth surface and avoid air turbulence. The shaped skin m has bowed portions n stiffened by ribs o welded or riveted thereto. The end rear portions of the skin may be similarly stiffened as well as portions on the top of the body behind the driver's head. The front portion r, Fig. 1, may have no stiffening but may fit like a cap over parts s of longitudinal members h, i, of the supporting structure. The skin is tilted to engage the front r and may be made sufficiently elastic to be sprung into position and remain elastically. The tops and bottoms of the ribs o, Fig. 3, may be bolted or welded to the supports h, i. This avoids deformation of the skin. The assembled skin and supports are lowered on to the chassis in bent portions k, Fig. 1, of the frame accommodating the wheels. Flanges l, Fig. 3, rest on bearers b on the chassis. Instead of the stiffening ribs n being on the skin m, similar ribs n' may be provided on the supports. In this case the outer skin should be made elastic so as to splay apart prior to being welded or riveted in position.

[Class 6(iii)] [Also in Group XXX] A machine for elevating hay of the kind having a wheeled frame, a jib supporting an endless conveyer and a hopper has the wheels at the hopper end of the frame carried by a two-part member to one part of which the wheels are attached and the other part being pivoted to the frame so that the frame may be lowered, and the two parts being so connected that the wheels carrying part may be turned relatively to the other for steering purposes. In the construction shown, the wheels D at the hopper end of the base frame B are mounted on a cross member E attached to a turntable G, for steering purposes, which is attached to a second cross member H, carried by arms J, having stub axles K engaging in bearings in brackets L, secured on the base frame B. A toothed quadrant M on the axle K has engaging therewith a worm N on a shaft O carried in a bearing in a bracket P on the base frame B. Rotation of the shaft O turns the member H and thereby the member E, the turntable being locked by bolts G<SP>1</SP> during this process. A spur wheel and pinion connected to the cross member, or any other suitable mechanism may be used to adjust angularly the cross member and so lower the hopper.

A rotary conveyer comprises a co-operating pair of members 12, 13 each having sets of radially extending arms 12a, 13a, each arm 12a being parallel with a corresponding arm 13a, a support member 17 being carried by each such pair of arms 12a, 13a. Thus work-holding containers 1 carried on respective members 17 can be rotated from a loading station B. through an intermediate load-storage station C to a station A at which work is first performed on workpieces in the container, after which the latter is unloaded. The containers 1 slide from the upper run 5 of an endless conveyer down rods 2, 2, and rollers 7 into a tray 24 which is carried by the member 17 and is automatically tilted at the station B from a normal horizontal position into a sloping position in alignment with the rods 2. The automatic tilting is brought about by the interaction of cam surfaces 20a on sleeves 20 axially slidable on a pin 15 projecting axially from the outer end of a respective arm 12a (or a pin 16 projecting from an arm 13a, as the case may be) with a pin 18 fixed to, and extending radially from, the respective pin 15 (or 16). The two sleeves 20 in respect of each support 17 are joined by a link 19. Rigid with each link 19 are a pair of links 21 which are connected to arms of respective bell-cranks on the other arms of which is mounted an associated tray 24. Rotation of the members 12, 13 is normally prevented by a pawl releasable by a hand lever 25. The members rotate under gravity due to the weight of each container 1 in the tray at station B.
