Patented Aug. 22, 1933 1 QEEI MACHINERY FOR HANDLING lCHASSIS 1- FRAME Christopher F. Coda, Detroit,. Mich., .assignor vto TheMurray Corporation of America, a vCor-1 poration of Delaware Application August 12, 1930.: Serial No. 474,7,64
13'Claims. (Cl. 1918-20) As maybe inferred from the-aboveftitle, it is an object of this invention Jto-provide means wholly-or largely obviating reliance upon manual l labor in the handling of heavy units such as the chassis frames of automotive vehicles.
It being-customary to'advance heavy frames of the-general character referred to, from one operation to anotherror from a final operation to a point of delivery or storage, by means including an overhead or upper chain conveyor provided with vhoolrs from which the frames freely del object of this invention to provide a lower conveyor advancing at a sufliciently higher rate to permit the mentioned frames to b e disposed upon the latter in an orderly arrangement, and preferably end to end; and the mentioned intermediate meansmay advantageously be driven from one or the other of said conveyors and at a rate intermediate between the rates thereof.
Inpthe use of overhead conveyors for the purpose referred to, it has been customary to employ a ground crew of men, these being sometimes aided by an overhead crew, said crews cooperating in the lifting of the successive frames from their respective hooks. The ground crews have been required to grab said frames and, advancing the lower ends thereof more rapidly than their tops until said frames reach an inclined or horizontal position, tc hasten away with each frame at such a rate as to permit the next frame to be similarly manipulated; but such labor is naturally fatiguing and not free from the dangers incidental to hurry and fatigue; and it is accordingly a general object of this invention to enable operations of the character referred to to be performed more economically, more expedi-y tiously and more safetly than heretofore.
Another object of the present invention in-V cludes the provision of a preferred type of frame f hanger, cooperating With both the mentioned upper conveyor and the mentioned intermediate transferring means-the latter preferably including both Va pair of laterally disposed and sprocket-driven chains, so spaced apart as to permit the lower ends of frames to advance there--` between, and also a pair of inclined guides eX- tending upward into a position of cooperation with said 'chains and downward into a position-of cooperation with the'mentionedA belt conveyor.
Other objects of the present inventionfin4 cluding features of drive'mechanism and of support for relatively moving parts; maybe best appreciated from the following descriptionof an illustrative embodimentvof the invention, taken; in connection-with the appended claims and the accompanying drawings.
Fig. 1 is a side elevational view, witlrpartsv broken away and with optional features includ-` n ed or diagrammatically suggested.
Fig. 2 is an elevational view, taken from theA general direction suggested `by the arrow2 of Fig. l.
Fig is a partial top plan view showing a power take-off from a conveyor chain, but with" parts broken away and with chains ofa transfer device omitted.
Fig. 4 isa side elevational .view, .enlarging a Central portion of Fig. 1.
Referringiirst to general features .of the il` lustrated embodiment of thepresent invention, upright'frame elements 10, 10C and 10a, ,1 0a
longitudinal horizontal frameelements 11,1111, llc, -11a ,and transverse frame elements 11b,
11b and 11e, llc areshown as employedto.
support .not only a rail,12 for an upper conveyor. compls'inga Achain 13, carrying hooks 14, Abut also bearing brackets-15, 15 and. 16, 16 for pairs of short shafts 1,7, 1'7' and 18, 18,-the lat-v tercarryingsprocket wheels19, 19 and\20, 20
over which4 extend block-carrying chains 21, 21`
adapted to advance successive `chassis, frames F, or the like, towardguide channels 22,- 22, ter k minating above Aa belt conveyor 23.,
Although the .mentioned guides 22, 22 `vmight' be usedin conjunctionwithany preferred, means for lifting Vsuccessive frames from the vadvancing hooks 14,1 shown as comparatively broadin a transverse direction; and although theA .chains 21 'mightbe sc eXtended as to bring the sprockets` 20, 20 tov any desired-lower level relatively tothe conveyor 2 3 (either of the mentioned -devicesof the illustrated transfer means being optionally eliminated) it will beobvious that the advancev at a linear rate such as-10 to 15 feet per minuta- .optional means for this purpose being, hereinafter described.
The vertical distance between;the upper conveyor 13 and the lower conveyor 23 is preferably` such that no matter what nmeans may be emindirectly from one of the conveyors 13 or 23 and 1 ployed to release the successive frames from conveyor 13, the lower ends of said frames come into engagement with the conveyor 23 at about the time that the upper ends of said frames are removed from the hooks 14; and it should be understood that, regardless of the specific character of the intermediate transfer means employed, such transfer` means should provide an unobstructed space therebelow and the relative rate of advance of the conveyor 23 should be such as to carry the lower end of each frame forward, by an amount at least equal to the length of said frame, during the descent of the upper end of the frame substantially to the level of the conveyor 23,--the linear rate of the latter being accordingly about 35 to 40 feet per minute in the case assumed.
Consistently with the foregoing, the showing .of means such as a sprocket drum 24, carried by a shaft 25 extending between posts 26, 26
(optionally employed to support the lower ends of the guide channels 22, 22') and especially the suggestion of intermediate drive means including sprockets 27, 27 on shafts 18 and 18 and sprockets 28, 23 on shaft 25, chains 29, 29' being carried over the respective pairs of sprockets, should be understood as merely diagrammatic and as indicative of the mentioned synchronization of movement, although power for the driving of mentioned parts may be obtained from any suitable source or sources. For example, a motor M controlled by a switch S in a circuit C may be employed to drive the shaft 25,-the
interposition of a clutch being diagrammatically suggested at 30 and reducing gear being omitted. But motion is preferably imparted to the respective chains 2l, 2l', by means imparting corresponding rotation `either to the shafts 17, 17 or to the shafts 16, 16'; and such motion Amay advantageously be derived, as above suggested, indirectly and wholly or largely from the chain 13, or its equivalent.
'in the preferred form, vertical frame elements 10a, 10a extend upward above horizontal frame elements llc, llc to a sufficient distance satisfactorily to support bearing brackets 31, 31 for a horizontal shaft 32. carrying both a bevel gear 33 and sprocket gears 34, 34,-the latter being disposed in the same vertical plane with similar sprocket gears 3,5, 35', on the respective shafts 17, 17 and adapted to impart motion thereto by means of socket chains 36, 36. Vertical shafts 37, 37 may then be supported in any appropriate manner, as by means of brackets extending inwardly from additional frame elements 38, 38',- the latter being shown as terminally connected with mentioned horizontal frame elements llc, llc', and the shaft 37' being shown as terminally provided with a bevel gear 39 adapted to engage with the mentioned gear 33; and motion may be imparted thereto in a novel manner by means comprising a sprocket chain 40. This chain is shown as extending over sprockets 41 and 41 provided upon the lower ends of the shafts 37 and 37. The links of this chain are shown as provided with outwardly projecting teeth or lugs 42, adapted to intermesh with links of the chain 13; and the shafts 37 and 37' may be unequally spaced from said chain, to facilitate an intermeshing of said teeth, for a driving eiiect upon chain 40.
Unless the upper ends of the frames F happen to include transverse elements and/or projections or elements suitable for engagement by the hooks 14 and projecting laterally to a sufficient extent to engage the chains 21, 21 and/or the guide channels 22, 22', use may be made of special hangers comprising rods 50. These are shown as provided with laterally movable hooks 51, 51' adapted to enter openings in the upper ends of the respective frames F, supporting the same in Vertical arrangementand as provided also with annular spacers or collars 53, 53,-between which the hooks 14 may be received in such manner as to centralize and orient the frames incidentally to the positioning of the same thereon; and although the hooks 51, 51' are shown as pivoted at 54, 54 for lateral movement, it will be obvious that the exact location and configuration of these hooks, as also the form and/or location of other parts mentioned, must depend upon the type of the frames F to be handled. Any separable hang-ers will naturally be returned to a loading station for repeated re-use.
The chains 2l, 21 may be provided with any suitable means, (engaging laterally extending elements such as ends 56, 56 of hanger rods 50 and such as blocks 55) serving not only to lift the units successively from the hooks 14 but to carry the' same forward and downward toward the guides 22, 22 and/or the belt conveyor 23; and it will be `understood that the form and spacing of the blocks 55 and the chains 21, 21 are intended to accord with the illustrated mode of operation. The lower end of each frame F or like heavy unit is preferably engaged by the conveyor 23 at the beginning of the descent of said frame after it has been lifted from a hook 14; and said lower end is thereafter carried forward, preferably without appreciable drag relatively to the conveyor 23, at such a rate as to deliver successive frames in a substantially end-to-end arrangement upon said conveyor,-the end portions 56, 56 of rods 50 being received successively by chains 21, 21 and by guides 22, 22' when both of these transfer devices are employed.
The intended mode of operation of all features of the present invention having been indicated in connection with 'the foregoing description thereof it may be mentioned that the laterally spaced guides 22, 22 if used may advantageously be or" either channel or angle section, the latter being shown, and disposed either in the same planes with the laterally spaced chains 21, 21' or in planes laterally offset therefrom,-the latter construction being practicable only in case the rods 50 extend to a slight extent beyond said chains, as shown; and it is again emphasized that chains 2l, 21', when used, need not be driven both from above and from below.
It will, however, be understood not only that various features of the present invention might be independently employed but also that numerous modifications, additional to any suggested herein, might easily be devised by skilled workers, if informed of the foregoing-all without departure from the scope of the present invention, as the latter is indicated above and in the following claims.
