LOADING-MACHINE.

Application 'led May 21, 1909. Serial No. 497,436.

Be it known that I, THOMAS MALLoY, a citizen of the United States,rresiding at Chicago, county of Cook, and- State of Illinois, have invented certain new ,and useful I mprovements in Loading-Machines,- of whlch the following is a specification.

My invention relates to improvements 1n "loadmg machines adapted foruse in conjunction with concretel machines, the object I of the inventioubeing to provide a machine of this character that shall be strong and durable in its construction and efficient in its' gravel or sand maybe drawn to a M invention will be more" readily understoo by reference to the accompanying drawing forming a part of this specification Flgure, `1 is ka side elevation 1of m imzgnovedv concrete 'machine in its pre erred form, and Fig. 2v is a top'. plan thereof.

Referring no'wto, the drawings, 1. designates `thefraine or body of the machine and 2 the. inclined track incorporated therewith up which carsor wa ons 3 ma be drawn by means ofthewind ass 4. iveted 'to the frameil' are yv e1ti cz 1l standards 5, in the lower ends l(')f'w'hich' the front wheel axle 6 is journaled;A andfin'n similar standards 7 the rear Wheel axle 8 journaled. The rear portion 9 vof the inclined track 2 is hinged to' themain' portion thereof and is adapted to foldinto the osition'as shown in dotted lines in Fig. '1 w enl not` in use, the pointed hinged portion l() serving ,as a uide to directthe car wheels'so that they will roperly engage the track when being rawn thereon.

The rotary mixing cylinder lljof ordinary construction supportedy on rollers and on pinions 13 which' mesh with gear rings .thereon and are adapted ito'rotate the same,

said rollers being rotatably mou'ln'ted on the horizontal frame lfipsuspended v,from the frame 1, and the pinions 13 being secured to the driving shaft 15 which is Journaled Patented Dec. 27,1910.

in the bearings'lG y rovided on said frame.

On the driving shaft 15a sleeve 17 is rota-7 tably and slidably mounted, and on this. sleeve the bevel pinions 18 are formed. Each` end of the sleeve 17 is bifurcated to en pins 19 secured in the driving shaft 15, length of said sleeve being less than the distance between said pins. When thepsleeve 17 is in the intermediate or neutral position between the pins19 there is no engagenngntV vof the p1nions'18 with any gear, but when said sleeve is moved along on the 'shaft 15 so that a bifuroated end of said sleeveenfA gages a pin then the bevel pinion at the other end thereof is adapted to enga a driven bevel gear 20' formed on a aft which is journaled in' members secured to` the frame 14. In order to slide the sleeve on theshaft 15 a rod 24e/having ahandle 25 is. shdably mounted on the' frame 14, and an arm 25 secured to said rod is provided with'- a bifurcated end adapted to engage a circumferential groove in the sleeve 17.- A sprocket provlded on the shaft 21 is connected by means ofthe chain belt 28 to a sprocke on the agile G. It will now be readily -seen that the machine will run in either dlrection according as to which bevel pinion is inmesh with the gear 20.

A-driven bevel shaft 15 which mes es with and is driven by the bevel ear 31 provided on the shaft 32, the lattereing journaled in the hangers 33. A driven sprocket? is provided on the shaft 32, and the chain belt 35 .traveling\.{on\the ear 30 isfornied on the'y driving sprocket 36 on the main driving shaft 37 is adapted to-drive the sprocket 34; It is clear that the rotary mixing cylinder revolves continuousl when the main driving shaft 37 is being criven -by -the chain 38 which is connected to the Agasolene engine 39 provided onthe platform 40, the latterv r0- eert@ fle-Sinin the Cream .from the gravel hopper 52 to thepropor tional hopper 53, and the conveyer 51 to` ca rry sand from theA sand hopper 54.tosaid proportional hopper having a partition 57.

y The operator standing onthe platform 41 ing wheel'G() is provided adjacent the open.

may empty the bags of cement into the pro? 'portional hopper as required, By Watching the raduations 55y and 56, the operator is enabed to tell when the proper lamounts-of sand and gravel are in their respective sides of the hopper 'and thus govern the proportions of the same in the mixture.

The shaft 58 is mounted in hangers 59 depending from the body l, the conveyer 51, traveling over sprockets provided lon said shaft, being 'adapted to receive sandv as it escapes through the bottom of the hopper 54. To regulate the flow of sand on to the conveyer from the hopper v54 a feed regulating of saidhopper, the same being secured to a shaft 61 journaled in andA projecting from the hopper. A sprocket 62 1s secure to the shaft 61 and is connected by means of a chain to a driving sprocket provided onthe shaft 58, the exact position of which Asprocket on the latter shaft not being shown.

The shaft 63 is mounted. in hangers G4 depending from the body 1, the conveyer travelin over sprockets provided on said shaft being adapted to receive gravel as it escapes through the bottom of the gravel hopper 52. To prevent clogging of the openinr in the bottom ofthe ravel hopper thc following means are provided: A reciprocating shutter '65 is mounted to slide across the opening of the hopper, and on said shutter a vertically rdisposed piny 6G is formed which acts as a shaker when reciprocating to loosen the gravel. The shutter 65 recipro- Cates in the rectangular guide tube (37 formed 'integral with the hopper 52, and to said shutter a bar 68 is riveted. This bar is pivoted to a lever 69 which is. fulcrumed on the stationary plate 70 and which is oscillatedrby means ot a connecting 4rod 71 connected thereto and' to the crank shaft 72,

' the latter' being journalcd in a hanger 73 depending from the body 1. A sprocket 74 is provided. onthe crank shaft, and it receives its motionfroma chainiadapted to `vention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to Amake such changes and alterations as `fairly fall within the spirit and scopeI ofthe claims.

l Having described. my invention claim as new and ters Patent is:

1. In a machine of the class described; a wheeled frame; an inclined car track on said frame, each of the members of said track terminating at, its lower end in a hingedsection adapted to contact with the ground; means for drawing cars onto said track; one or more receiving hoppel's located under said track; and means on said hinged sections for directing car lwheels onto said track, substantially`as described.

. 2. In a machine of the class described; a wheeled frame; an inclined car track en said i what desire to secure by Letframe; means for drawing cars onto .sa-id track; one or more receiving hoppers located under said track; and a pointed wheel guide pivoted between the lower ends of said tracks and adapted when in operative position to lie upon'the ground and direct car wheels onto said tracks, substantially as described.

3. In a machine -of theclass described; a wheeled frame; an inclined car track on said :trame lcomprising a pair of parallel members, a hinged section at the lower end of each of said trackA members adapted, to contact with the ground; meansfor drawing vcars onto said track; one or more receiving hoppers located under said track;

and a pointed wheel g'uide connected to and `upon the ground and direct c r wheels onto said tracks, substantially as escribed In testimony whereof -I have signed my name to this specification in yhe presence of two subscribing witnesses.
