These journals are fixed in forks sufch holding devices for piece goods, such as 6 whose upper ends by lneans of pins 7 are: 55 bags, bales, packages, etc., having a simple rotatably journalled on a carrying part 9 alld reliable construction and also adapted resting on the upper sides of the prongs of. for automatic loading and unloading, while the forks 6by intermediate axial ball bearings y.being'cheap'tomanufacture. 8 through which the pins 7 pass.

Said bolt'isy ,Figa 6 is a vertical section on the line looselyplacedbetween said two side pieces VI-VI in Fig. 1, also on a larger scale. 23 and prevented by flanges or washersBOa In the drawings 1 indicates a rail of flat at both ends from lfalling out of the slots 29.' loo Said bolt is also embraced by two loop-shaped members 31, whose shape is best seen from Figs. 1 and 3. The openings in the members 31 show three notches 32, 33 and 34 of such a size that the bolt 30 fits snugly in any of these notches. Each of the side pieces 24 carries a projection 35 at the base of which a notch 36. (Fig. 4) is made having a size corresponding to the diameter of the bolt`30.

The members 31 are rotatably journalled on a pin 37and'are keptiapart 'byan intermediate distance member 38. The pin 37 is iixed on a die 39 rotatably journa-lled between two link members 41, 41 at oneV end of said link members while the other ends of said link members are Vrotatably j ournalled on the journals 25."The die 39v lia-sa transverse hole throughawhich an operating lever 42 is loosely inserted. and'may be moved in 'its longitu-l dinaldirection. .Said operating vlever is# threaded to a part of its length and normally lockedzto the die 39by use oftwonuts 43 screwed onV the operating lever on both sides of said die and engaging the latter. The operating. lever is somewhat curved inthe einbodiment shown. YIt may consist of two parallelarms, ifldesired. At the outer end of the operating lever a roller 44 is rotatably journalled andthe 'oppositeor kinner end of said operating lever is rotatably journalled on a pin` 45..between two projections 46, 46 projectingfrom theside-

pieces

19, 19 of the. u-ndividedgripping arm.v

A- tension spring 47 is arranged between vthe pin 37 and-.one Vofthe side pieces 24. The

motion of the part 24-of the two-part grip: ping arm inrelation to the part 23 of said gripping arm-is limited by abutments 48 on the side pieces 24. Furthermore, abutments 48aand 486 arerprovided on the side pieces 24 to limit the motion ofthe link members 41 v in relation to said last-mentioned side pieces. When. the jaws are opened, the link members 41 ywill abut against the abutments 48a torotate the part 24 .of the two-part gripping arm in relation to the part 23 of the .same arm. Thus, the'jaws are rapidly moved apart even if nojload is held between them. i When the gripping arms are moved againsteach other .to yclose the jawsl said link members 41 will abutagainst vthe abutments 487; and cause the parts of the two-part gripping arm to rotate untilthe abutment 48 engages the part 23. The abutment :486 also serves to. limit the downward motion of. the operating lever A42.

The device described acts asfollows: When the parts are' in the positions shown'A in Fig. 1. the jaws Aare closedL and locked. This locking is effected by the operating lever 42 and the bolt 30, in as much as saidboltrests inthenotches 36 and thus keepsthe .part 24 rigidly. locked to the part 23 of the two-part gripping arm, said part 24 engaging the abutT ments 48 andY 35 andbeingthus kept in position so that the parts-23,A 24 act as one single link'm'embers 41 and also by the abut-ment lever 42 would keep the jaws and gripping arms locked even-if the'special locking device 485. Itis to be observed thatthe` operating 28-,36 was not provided for.

"IV'hen the hold ofthe jaws is to be released to free the load held between them, the operating lever 42 is moved upwards. .This is done either by hand or automatically. In said latter case the roller 44 is caused to be liftedby a stationary operating rail 49 (Fig.

1) arranged obliquely beside the rail 1, when the roller 44 engages said rail 49 at the forward motion of the holder on the rail 1. Then the roller 44 thus is lifted, it swings the operating lever 42` upwards on the journal 45, thus causing the-link members 41gto swing on thejjournal. 40 andto move the journalsV 25 which are then moved outfrom the journal 45, so that the jaws 21, 26.are moved apart. Simultaneously, the members 31 are moved upwards and push upwardsand inwards the l locking bolt 30 resting in the notches 32,:thus

' lifting said bolt out of the notches 36, so that the locking. between the parts 23 and 24 of theYtwo-partgripping arm is released. Imf mediately after the beginning of the upward motion of the operating lever 42 the part 24 f of the two-part gripping arm is freedvand Inay rotate freely on the journals 25. Thevr piece of goods held between the

jaws

21 and 26 will be momentarily freed in this moment y and push the free part 24 outwards. Consequently, the jaws are opened'veryrapidly to theirmaximum width and the piece of goods is effectively prevented from beinghooked on to and possibly torn by the jaws anda correct operation is always secured. When the operating lever is thus moved upwards the link members 41 will engage the abutments 48a and aid in swinging the part.24 in relation to the part 23, so that a rapid opening motion is attained. Even if nofload is. placed between the

jaws

21, 26,.the latterwill yet be opened positively byrmeans of the abutment 48a.

It is evident that the distance between the jaws in lthe locking position shown in Fig. 1 or. in other words, the minimum width of the jaws may simply and easily be 'adjusted .Grip and hold objects of very dif` bleways, etc.

sume a different angular position,\a`lso slideupwards so that said bolt-slides out of the notches 32 and into the notches 33"or even- 34.- After this the operating lever can continue its movement upwards and move the

jaws

21, 26 still fartherapart, independent of the fact that the upward movement of the bolt 30 is limited by the upper ends'ofthey slots 29'- Now the various parts have the positions illust-rated in Fig.

When the operating level is pusheddown, the various parts of the holder are moved to their locking positions again. The spring .47

will press the part 24 ofthe two-partk gripping arm to engage the part 23 of said gripping arm tightly by the abutments 48, thus causing the notches 361to'coincide with the lower ends of the slots or'grooves 29. After "tion. Independently of this, the link inembers 41 will, however, abut against the abutment 48?; to turn the part 24 iii relation to the part 23, until the abutment 48 engages the part 23. After this the parts 23, 24 form a rigid structure, constituting the second grip ping arm. The engagement of the link members 41 with the journals 25 cause at the same time this gripping arm 23, 24 to be returned to the closed position and to be locked in this position by the operating lever. The downward movement of the operating lever to close and lock the jaws as described may be efected by hand or automatically, for instance by a spring (not shown) or an oblique rail, similar to the rail 49 but engaging the roller 44 from above (not shown).

In the embodiment shown, more than one different device is used for the same purpose, particularly for locking the parts, for moving the parts 23, 24 together to form a rigid unit and to move them apart. The holder will evidently function even if such doublings of the devices are not at hand. Particularly the locking device 28-36 may be omitted, if

desired.

The holders or carriers in accordance with this invention may be used in combination with wagons for suspended lines of various types, such as suspended railways, aerial ca- Their motion along the line may be originated in any suitable or wellknown way. For instance, the holders or their wagons may be attached to a rope or chain running along the rail 1 or may be engaged by catching devices attached to Vsuch rope or chain. In this latter case side-rails and switches may be provided so that the holders with their loads may be switched to diierent rails and distributed in any desired -The rail 1 mayalso be slanting so that the holders are moved forward bygravity;l A special plant based upon this principle is described in my copending U. S. patent application Serial No. 550,022 mentioned above.

Because suspension lines having holders in accordance with the invention require very' little space and may easily be constructedfto f follow almost any vertical or horizontal curves desired, such lines are very useful'for solving many transportation problems which otherwise would cause very high costs.
