To all whom it may concern.'

Be it known that 1, KNUTE S. SA'rnE, 4a citizen of the United -.States, residing at Frost, in .the county of Faribault land State of Minnesota, have invented certain new and useful Improvements in Shock-Loaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to that class of nieehanism generally designated as shock leaders, and in its preferred 'arrangement is in the nature of en attachment to a bundlereceiving wagon or truck, and is arranged to pick up shocks of loosely assembled bundies and to elevate and deposit the some in the Wagon box, under the forward movement of the Wagon or truck, and through the intervention of power transmission connections between the bundle or shock engaging fork and one or more oi' the traction wheels `oi' thc said wagon or truck.

. after described and de'lned in the claims.

.In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a View in right side elevetion, showing a wagon having niv improved bundle-loading attachment applied tl'iereto. Fig. 2 is a plan view of the same, with some parts broken. away. Fig. 3 is a rearelevation ol the parts shown in Figs. 1 and Fig. 4 is e rear elevation withsome parts broken away, showingthe fork and supporting frame therefor, swung backward, preliminary to the bundle or shock discharging movement thereof. Fig. 5 is a view in rear elevation, showing the fork and the supporting l'rame 'therefor in its uppermost or bundle discharging position.. Fig. f5 is an enlarged 'view in right side elevation, and with some parts broken away and some pnrls sectioned, showing the fork, its supporting frame, :ind ccrtnin nsso- Cizxted parts. Fig. 7 is :i view rhielly in plan, but with soun` pi'ir'ts in horizontal section, showing the mechanism illustrated in Fig. Fig. S is a detail 'view in plan showing the right hund member ol' :i pair el" .so--

Called clutch opcrziling chains and nssoclated parts. Fig. 0 is a-vertical section taken approximately on the irregular line of Fig. S. Fig. 11) is a detail view in plan, with some pnrts broken away, showing the leit hand member of the pair of .so-called clutch operating chains. Fig. 11 is a vertical section taken approximately on the irregular line a5 o'l`. Fig. 10. Fig. 12 is a detail in vertical section taken centrally through the meci'uinism shown i-n Fig. 10, .approximately on the line si :rw o1' said Fig. 10. Fig. 13 is a transverse vertical section taken on the line .fr-I in o i Fig. 12. Fig. 14 is a transverse section token on the line az fr. oi Fig. 1t). Fig. .l5 is a detail in vertical section, taken approximately on the line oi Fig. 8; :ind Fig. 1G is a transverse vertical seclion, taken on the line at ol'A Fig. 15.

The numeral 1 indicates the wheels, the numeral 2 the 'framework or running gear, und the .numeral 3 the large bundle receiving box oi the wagon or trucii, which wagon or truck may be of anyT suitable construction. As illustrated in the drawings, the right hand rea-r wheel 1 is used as a traction wheel, and is provided on its huh with a driving sprocket 4. Mounted in suitable bearings on a rearwardly projecting portion ot the framework 2, is n transverse shaft 5 that carries three sprocket wheels, o, 7 and A sprocket chain S) runs over the sprockets 4.* :unl G and thus transmits motion, under the 'forward movement oi the wngon, from the traction wheel to the said `shnl`t 'lhe functions )erformed by this shnl't 5 will be described inter on.

handside oll the wagon box -E, is nn upright post or column 1() which, :is shown, is sccured at its lower cnd to the projectiiig end of one ol the trai'isverse bcnms oi the lriunework 2, und ut itsinterniediatc portion is connected to thc bottom ol' the bo.\ I by nn inclincd bruce lever. A heriyenlall)r swinging upright i'rame 1; is hinged tothe upright 10, prei'ernbly by moans oi n. vertical hinge rod 13 which, as shown, is rigidly secured to the transverse arm ol' said swinging trame. liigidly secured to the outer portion. of the frame 12, :it its intermediate portion, is a horizontal hinge rod 14, theI inner end of which is rigidly secured lo the said vertical hinge rod 12, :is best shown in Fig. 3. A rectangular l`ork-su1porting I'rnmc 15, which is capable olI vertical swinging movements, is pivoted on the said horizontal hinge rod 14.

Rigidly secured, :is shown, lo the right pivotally attached to said shaft 18 just in-v ward of said sheaves, are inclined stop links 20. These stop links 20, at their upper ends, are provided with elongated slots 21 that pivotally slide upon the projecting ends of a transverse'stop rod 22, the end portions of which are secured to the vertical legs or side portions of the vertically swinging frame 15. The stop links 20 limit the downward movement of the fork to the position shown in Fig. 1, but permit the same an initial rising movement shown in Figs. 4 and 6, which movement is suilicient to raise the shock, caught by the viorkhirom the ground. The bundles which constitute the shock are indicated by the character e. The inner end of the rock shaft 16 carries a trip arm 23, for a purpose presently to be noted.

When the fork is in an operative position, or in a position to pick up a shock of bundles, the laterally or horizontally swinging frame 12 must be held in a position at a right angle to the box 3, and this result is accomplished by means of a so-called lock rod 24,. the outer end of which is pivotally connected to the lower end of the outer portion of said frame 12 (see particularly Figs. 6 and 7) and the inner end of which works in a sto bracket 25 rigidly secured to the right hand side of the wagon frame 2. The rear end or inner end of the said lock rod 24 is' headed and normally bears against a stop flange 25a of said bracket 2.5,while the rod itself is capable of a limited vertical movement in a slot 25b of said bracket. When the headed Gnd 'of the saidgrod 2li. israised, as shown byv full lines in Fig. 6, its headed end will move freely over the stop flange 25, so asto permit the rod to slide throug'h the slot 25h, and.

thereby permit the frame 12 to swing laterally backward and inward, carrying therewith the frame 15 and thefork into the posi# tion shown in F ig. 4. By reference to Fig. 4 it will be noted that whenrthe said fraine 12 swings into the position shown' therein, the

lower endof the fork supporting frame 15- strikesl the lower end of a stop' bracket 26 fixed to the wagon box and the frame 2, thereby forcing the lower portion of the said frame 15 away from the lower portion of said frame 12.

For the purpose of moving-the lock rod 24 into its releasing osition at the proper time, to-wit, after the ork has been given its initial upward movement into the position shown in Fig. 6, the 'following connections are provided: The numerals 27 and 28 indie cate a pair fof heil cranks, the former oi which is pivoted to a bearing 29 on the trarne 2, and Vthe latter of which is pivoted to a bearing 30 on said frame. The upwardly extended arm of 'the beilcranks is connected by a rod 31. The rearwardly extended arm of the bell crank 27 is connected by a rod 32 to the rear end of said lock rod 24. The forwardly eX- tended arm ofthe bell crank 28 is connected to the upper end of a depending rod 33 that works through lthe lower portion of the bearing 3() and has alaterally bent lowerend that directly underliesthe trip arm. 23 of the rock shaft 16. With this arrangement, it is evi dent when the fork is moved upward, as shown in Fig. 6, the trip arm 23 presses the rod 33 downward, and, through the connections described, raises the lock rod 24 into iis frame releasing iosition. f

Mounted in suitalile bearings at the iront end of the truck frame 2, is a transverse sii-aitk 34 which, a't its ends, carries sprocket wheels 35 and 36, respectiveiy, thataline with the sprockets 7 and 8 ot the heretofore described shaft 5. Sprocket chains 37 and 38 run, respectively, over the said sprockets 7 and 35, and 8 andj36. p

The upper portion or" the "left hand clutch chain 38 works over a skid or horizontal support 39 (see Figs. 10, 11, 12 and 13)'that is rigidly secured to the projecting left hand end of thetransverse timbers ofthe truck frame 2 (see F igs. 3 and 5). The right hand clutch chain 37, at its upper portion, works over -a skid or horizontal support 404v (see Figs. 8, 9, 15 and' 16) that is likewise secured to the projecting right hand ends of the transverse beams of the truck frame 2 (see Figs'. v 4 and 5).

Extending along and over the skid 46 is a ric long guide channel, shown as formed by laterally spaced angle strips Lilgrigidly secured, to the sides of said skld, as best shown/ in Figs. 8, 9, 13 and 16. Working in this guide channel, between the said guide stripsvfil and just above the upper portion oi the chain 37;

1s a sliding clutch block 42, provide-d oirit's/ upper face with an undercut lock lug 43, and at its rear end wi th a cable anchoring lug 44. Pivoted to the forward end of the clutch block 42, isa lock dog 46 provided atits free end with a chain-engaging lug 45, and with a `forwardly extended tripping lug 47. Said dog 46` is also provided with a rearwardly extended arm 48 that is provided with a depending pivoted gravity-actuated. lock hook 49, adapted to engage 'with the lock lng 43 1 to hold. the clutch dog 46 out of engagement. with the chain 37. The clutch dog 46 when the hook 49 is' disengaged from the lock lug 1,30l

emerse 43, 'drops into the position shown in Fig. 8 From the guide sheaves 64, the upper and and its lug 47 engages with one of the links of the chain 37, thereby locking the said parts 42 and 46 to said chain for movements therewith toward the front end of thel wagon box. When the said forwardly moving parts reach theposition shown by dotted lines in Fig. 9, the trip lug 47 of the dog 46 engages the free endo'fan arm 50, which is carried i y a transverse rock shaft 51 mounted in a suitable bearing 52 on the front end ol`l the skid 4() (see Fig'-8) and in suitable bearings on the liront end of theframe 2. Vfhen the saidparts reach the position shown by dotted lines in Fig. 9, the arm 50 raises the dog 46 so that the hook 49, under the action of gravity, rengages with the lock lug 43 of the sliding block 45, thereby securing said dog 46 iii its inoperative position with the said parts 45 and 46 released from the chain 37 and free to make their' re turn movements together.

Extending transversely across the intermediate portions of the lfoi-lr rines 17, and mounted to slide laterally thereon in front of the tie bar 18,is a trippiiigbar 53. rlhis tripping har 53 is rigidly secured to a pair ol" sleeves 54 that slide upon an adjacent pair ol" the intermediate tines 17. (oiled springs 55 on cert ot the tines are compressed hetween t .tie bar 18 and the tripping rod 53 and yie'dingly press the latter forward. Mounted on the same tines as the sleeve 54, but at the rear thereof, is another pair ot sliding sleeves 56 which, as shown are connected by a couplingpin 57. A rigid coupling link 58 connects the said pin 57 to the tripping rod 53, all as best shown in Fig. 7, but also in Figs. 1, 4 and 6.

A le'ver`59 (see Figs. 1, 6 and 7) is intermediately pivoted to a bearing 60 on the right hand portion of the l'rame 2. rl`he lower end of this lever 59 stands.1 in position to be engaged and pressed rearward by a lrearward movement ol" the tripping bar 5?;

when the fork is in operative position. A. tripping rod 61 which works in suitable bearings 62 on the frame 2, ispivotallyconnectful at its forward end to the upper end of the lever 5). The rearend ol this tripping rod 61. is bent laterally at'62, and in the normal position of the parts shown in Figs. l, S, 6, 7, 8 and 9, stands in position to engage th(` rear face of the hook 4). With this construct ion, when the tripping bar 52% is forced rearward, the tripping rod 61 will be drawn l`or\\ ard and thereby release the hook 4!) l'rom the loclr lug 43, andtliereby pci-mit the clutclrdog 46 lo interlock with 'the pin 37, as shown in Fig. E).

'lhc numeral 62') indicates a cable, the ends of which are securely attached to the lug 4l of the sliding block 42. 'l`hc upper and lower portions of the cable (lil pass partly around a pair of guide sheaves 64 mounted on the rear portion ol thc right hand angle bar 41, see particularly Figs. 2, 8 and 9.

lower portions oi the cable 63 pass. to and partly around a pair ot vertically .spaced guide sheaves 65 (see Figs. 1, 2 and 8) which sheaves are mounted on a bearing 66 secured to the frame 2. F rom the up er sheaves 65, the upper portion of the ca le 63 passes to andpartlv around a swiveled -guide shcave 66, (see Figs. 1, 2, 3 and 5), on the outer portion of the frame 12. From the lower sheaves 65, the cable extends to and partly around a guide sheave 67 on the upright post l() (see Figs. 1, 2, 3, 4 and 7). From the sheave 67, the cable passes upward to and over a guide slieave 68 mounted on the upper end of the post 10. From the guide sheave 66, the cable 63 passes up to and over a guide sheave 69 on the up er outer portion of the horizontally exten cd swinging trame 12 (sec Figs. 1, 2, 3 and 4). From the sheaves 68 and 69, the cable 63 passes downward to and under thc guide v1) on the tie bar 18, and from the said'sheaves 19 said cable passesto and partly around a pair of guide sheaves 70, located. on the lower ends of the inner and outer portions ol` the vertically swinging frame 15. 'lhe cable 63, it will thus be, noted, is so disposed and guided, that when its ends are draw-n forward by the engage ment ol the clutch dog 46 ol' the sliding block 42, with the chain 37, as already described, the strain on the said cable would 'lirst raise the fork 17 as liar as permitted by the stop lugs 2() andV far enough to carry the bundle of shocks above tht` ground. \Vhen the lines of the forli are lorccd through or into the bundles ol the shock, sonic one or more ot the said bundles will engage the tripping bar 524 and thereby lorce the same rearward and causo thc clutch dog 46 to be engaged with said chain 37, as already described.

'lhe upward movement ol" the. li'ork, as already described, causes the tripping arm 23 to depress lhc rod Ill and through the connections 2, 2H, 3l and 32, to move the lock rod 24 into a trame releasing position, shown in Fig. 6, so that under continued pullingsi rain on the cable 62, the l'rame 12am] parts carried thereby will bc movcd or swung rearward und i n\\ ard, into thc position shown in Fig. `l. when the paris have been moved into the position shown in Fig, 4,'l`urther pulling strain on the cable (S3 produced by continuous l'orward movement ol: the clutch block L15, under the action ol' the chain 37, will carry tho lramc l5 pivolally upward and into the position shown 1nv Fig. 5v, in which position the bundles will be thrown in'tothe wagon boiY` il, partly under the action olE gravity and' purly by their o\\ n momentum.

When this lramc l5 and l`or|r carried thereby are tlu'onn lo ille cxtreme upper positions just noted, thc upper portion ol the cable 63 is temporarily carried oll l'rom thc sheaves esente dropping from the forkunder t 68 and 69, and is throvmjagainst a pair of guide sheaves 68a and 69, respectively, on the post 10 anden the frame 12. By direct pull on the cable 63, the frame 15 and fork will be positively moved upward, far enough to carry the weight of the shock beyond a vertical dead center, or beyond the .upright 10, so that the weight of the shock Willinsure the completion of the movement of said naine 15 and fork to the position shown in Fig. 5. The numeral 71 findicates a' platform secured to the frame 12, and which normally stands above the bundles on the fork but which, when the framel 15 is inverted, as shown in Fig. 5, underlies the bundie and prevents the same from prematurely ing movement of the trarne.

We have. now described ineens whereby, under ower transmitted through the right hand c ain 37, the iorkland the trarne which carries the same are swung laterally and'then raised to discharge the bundle from the fork into the wagon box. We will now describe means for effecting the return movement of the fork and the frames which carry the same. Extending longitudinally of and just over the skid 39, which is at the left side of' the box', is a guide channel formed by laterally spaced angle strips '72`,(sce Figs. 10, 11, 12 and 13), and extending forward ol said skid and guideV channel, and constituting an eX- tension to the latter, is a guide channel formed by laterally spaced. channel bars 73 (see Figs. 1'0, 11 and 14). Arranged' to slide in the alined guide channels just noted, is a sliding block 42* that corresponds, substalb tially, to the sliding block i2 and provided with an undercut lock lug 43a. Also, to the front end of the block 42 a chain engaging dog 46a is pivoted and is provided with a qhain-engaging lug 45, a tripping lug L17Lt and a rearwardly extended arin 4S, to which arm isA pivoted a lock hook 49a. Vilhcn the hook 40 is engaged with the lock lug 43a, it holds lthe clutch dog 47"* with lug 45a out of engagement with the chain 33.

The sliding block 42- is provided with a supplemental section 74 that is normally connected thereto by a coupling hook -75 that engages a lug 7G on the said block 42, as shown by full lines in Figs. 11 and 12. The coupling hook 75 has a laterally projecting pin 77 that is adapted to be engaged with a cani'lug 78 located on one of the channelshaped guides 73, at the intermediate portion thereof (see Figs 1() and 11).- A.Located below the up er portion of the chain 38 and unted to slideV in the guide channel formed b'tween the channel bars 73, is a secondary sliding block 79 which has a depending leg 80 and a pair of upwardly projet-.ting lugs 31. 011e end of a frameereturning cable 32 is at tached to the leg 80 of said secondary sliding .Wagon box.

dischargblock 79. The other end, to-Wit, thelear end, of this cable 82 is connected to and works upon-a windlass drum 83 carried by a countershaft 84 mounted in suitable bearings on the rear portion of the frame 2, and pr0- vided at its other end, to-Wit, its right hand end, with a small windlass drurn 84a. A11- other cable 86 is attached to and mounted upon the drum 84a and its forward end is attached to a coiled spring 86a which, in turn, is attached to an armS, which arm is rigidly securedA to the lower inner portion of the swinging frame 12 and works below the The cables 32 and 35 are Wound in reverse directions on the respective Windlass drums, so that when one is wound up the other'will be unwound. Still another cable 88 is attached at one end to the supplemental section 74 of the sliding block 42a, and at its otherA end is attached to the transverse rod 22 of the vertically movable frame 15'(see Figs. 3, 10- and 12).` This cable 88 is guided by Guide sheaves 39, 90, 91,92 and 93. The guic e sheave is j ournal-ed on a braclietQ/i that forms an extension oi the inner angular guide bar 7 L. (See particularly Figs'. 10 and 11). The sheave 9() is journaled on a bracket A95 secured to one of the rearwardly projecting beams of the frame 2 (see Fig. 2). The sheave 91 1s Ieurnaled on a bracket 96 that 1s rsecured to the lower portion of the swinging frame 12 (see Fig. 2).

The sheave 92 is directly journaled to the lower portion or' said frame 12 (see Figs. 2 and 3). The sheave 93 is j ournaled in bearings 97 secured to the lower portion oi said traine 12 (see Figs. 2 and 3). y

A wide-faced sheave 98 is journaled in a bearing lbracket 99 that is rigidly secured to' the central portion of the non-rotary hingel rod 14. v When the frame 15 is inverted or moved upward into the position shown in iiig. 5, the upper portion oi the cable 88 engages temporarily with the sheave 98 and is thereby ailorded a guide over which to pull, to thereby accomplish the initial return or dmvnward movement of the said traine 15 and the/.fork carried thereby.

The roel: shaft .51, heretofore noted, is

,provided at its left hand end (see Figs. 2, 10

and 11) with a second arm 10G to which the forward end ot a trip rod 161 is oivotally attached. This rod 101 is suitab y guided by one 'or more bearings 102 on one oi the angle guides 72, and at its rear end, is provided, with jalaterally bent end 103 that stands in positioi'i to engage the liool{.49"?and disendage the saine froihsthe lock lug 43a.

" As shown in Fig. 2, the sliding blocks/l2 and 42E are connected by a cable 10st that runs over guide sheaves 105 journaled 'on brackets 106 on the front portionvof `the frame 2. By means of this cable 104,"whcn the block 42 is released and is put under strain to nieve rearward, it is prevented from moving rearward faster than the said block 42* is carried forward by the chain 38. A summary of the operation is as follows: When, under the advance movement of the machine, the fork tines 17 are run through the bundles of the shock and one or more ol' the bundles is thrown against the tripping bar 53, the right hand cutch dog 46 is enaged with. the chain 37 in a manner already escribed, and the frames 12 and .15 will be swung rearward and inward, 'first into the position shown iii F ig. 5, iii a manner also above set forth in detail. When, after the bundles have been discharged into the wagon box by the upward movement of the fork, the trip lug 47 of the clutch dog 46 enffages the arm 50 of the rock shaft 5l and theiook 49 is permitted to again connect with the lock lug 43, the said rock shaft 51 and its arm 50 are moved into the position indicated by dotted lines' in Fig. 9, and the right hand clutch is then uncoupled from the chain 37 and is capable of return movement. This movement of the arm 50 and rock sha-tt 51 carries the arm 10() forward, together with 'the trip rod 101, and causes the end 103 of the latter to move the liooli 49 out of engagement with the lug 455, thereby permitting the dofT ttL to couple with the chain 3S. When this Telt hand clutch is coupled to the chain 38, as shown in lFig. 11, it ol' course moves forward with the said chain. ApproXimately the first one-half forward movement of this left hand clutch, by drawing the cable S8, positively draws downward the inverted Vtraine 15 and fork carried thereby. Simultaneously with the return ol' the l'rame 15 to the position shown iii Fig. d, the pin 77 of the coupling hook 75 comes into engagement with the cam lug 7S (Fig. l l) and disengages or uncouples the supplemental block sections 74 from the main block section 42, so that under 'forward movement of said block 42* no further pulling movement will be exerted on said cable SS. Simultaneously, or approximately so, with the separation of the supplemental block 74 from the main block 42, the said main block comes into contact with the lugs Sl of the secondary sliding block 79, so that umler continued forward movement ol' said block 42, the cable S2 is drawn forward and unwound from the drum S3, while the cable S6 is drawn rearwardand wound onto the drum SAPR This rearward movement olI the cable S6, acting thiougli the arm S7, swings the l'rame 12 and parts carried thereby l'rorn the position shown in Fig. 4 outward and forward into their normal position where the said l'ranu` 12 will be locked by the lock rod 2a in amanner already clearly set l'orth. When the left hand clutch dog d6 reaches its extreme forward position, as shown by dotted lines in F ig. 11, a pin 107 comes into engagement with a fixed cam 108, which cam releases said dog 46 from the chain 238. When the frames llZ and 15 are again given their pivotal or hingelilie bundle discharging movements, the cables 82 and S8 will be drawn rearward, thereby accomplishing the return movements of the sliding blocks 7l), 46 and 74 to their normal positions shown in Fig. 1l.
