ELEVA'IOR.l

To all whom it may concern: Y

Be it known that I. Sioirt'xo L. GoLnMAN. a citizen of the United States. residing at Chicagorin the countv of Cook aud State of Illinois. have invented a new and useful Im- ..1n:1vement in Efevators` of which the following is a specification.

illy invention lrelates to certain new and useful improvements m elevators, and is l-fullv described and explained in the specification and shown in the accompanying drawings. in which: l

Figures l and la areside elevations of my improved elevator and the parts normally placed adjacent thereto in' operation. Fig. 1 representing the lower part of the. elevator and Fig. l the upper end thereof` Figs. 2 and 2* are views taken in longitudinalV section .illustrating the lower and upper portions of the elevator, respectively., F ig. 3ds a topplan of the discharge-end of the lower gravity conveyer from which the articles carried pass on to theelevator; Fig. '4, a dct ailed perspective of'a portion of the ap iaratus shown in Fig. 3,; and Fig.,5./a. top pl)an of the elevator,..a portion 'of t-lie`siclerails common.

Referring to the drawings`A is the lower end of a gravity conveyer comprising a framework and rollers upon which boxesor similar articles may move by accordance with the practice which is now A1 isa discharge-slide which is pivoted Vbetween its ends to the lower end of the gravity-conveyer, as illustrated in Fi 1. 2, 3 and 4, from which it will he'seen't atl the discharge-slide is so arrangedthat when in its lower position, it. will h ave its upper end projected into the path of the articles moving on the convegver so as to stop their movement as shown in Fig. 1, and when raised to the position shown in dotted lines in Fig. l, will have its upperend so depressed as to permit their passage thereover. Downward movement of the discharge-sliderbeyond the position shown in .solid lines in Fi 1 is prevented bv the engagement of pro] ecting ears a.; with fingers a? on the lower end ofthe 4convever.

and at its upper and forward enda shaft ZH,

upon which shafts are mounted sprocketwheels over which run chains C. The cha ins are guided i'n channel-irons b2 which ruu along both the upper and lowerhorizontal and curved portions of the convever and'continue throughout the lower slanting portion thereof. and angle-irons b3 which' extend along the upper portion of t-he slanting part of the conveyer frame. the said angles and vso channels being disposed attheir flange ends,

tlieangles having their flanges beneath the chains to prevent sagging thereof. Atintervals along the 4cham C are .located brack- .ct's 'which are opposite to each other upon the two chains and .which said brackets arc connected b v cross-bars C1, the bracke'tsand cross-bars forming together flightsfor the propulsion of articles. Two links in advance of each of the brackets area series of cross? barsCz. I ving inV the plane of the chain and oil the next preceding links are a. series of flat cross-straps C3, C, thejlinks C carrying the en 'ds of' which are curved ownfwad"asI the curve for a shortdistance and the'cenp t-ral straps'D1 for a somewhattance upward. p l

E is an upper conveyor, in form like the conveyer A, so positioned as to receive argreater dis# ticles delivered by the elevator in the manner to be explained. l

- The manner of operation of the'entire structure is as follows: The parts normally occupy positions as shown in Fig.f 2,f in which the boxes or cases on the conveyer A are arrested b v the upwardly rojecting end of the discharge-slide A1. [j sone of the flights. moves alongras to the position show-n in dotted lines in Fig. 1. it 4 raises thedis; charge-slide A1 to the position' shown in dotted lines 'in that figure", and the lastl box or case in 4 the series moves onto the discharge-sllde, sliding down the same after the, flight advances and'permits the disV 4shock or tion. Tliilsai'tier the passage of a flight past the discharge-slide one box or case will be 'found in anincline'd position on the discharge-slide vwith its lower forward corner the itto fall flat on the fingers C5 upon which it will move forward until said fingers are inclined vby passing upthe angular part of the elevator upon which the box will slip backward. taking a position first like that shown by the rear-most box illustrated in dotted lines in F 2 and finally, when the curve is completely past by the flight taking the position shown in dotted lines for the second box, after which the box or case occupiesl a fixed and definite relation with reference to the flight and fingers and may be carried for any distance'upward withrelative movement between said ately below the level of the chains is filled .up' m'ore or 'less completely by, the straps which extend upward vto apo'mt at which the box or case takes its final vadjustment after which they are no longer necessary.

When a box or case reaches .the upper end of theelevator andthe fingers Cs upon which it principally rests begin to turn-with reference to the' flight, the box moves through the various positions illustrated in Fig. 2*, being finally' discharged without jar onto the upper. conveyerA as illustrated.

It is to be seen that. the 4elevator thus described is simple and lcheap in its construe# tion, that its operation is certain and that the' box or case is subjected to no considerable jars'by which it or its contents might be injured. The construction as a Whole is thoroughly etlicient in operation and is free from the objections ap lying'to many types of elevators particular y in that there is no opportunity for the box to be pinched between the ilights and any. projection either in the chain or .its connection or on the elel va'tor itself, as is the case with chain elevators and certain other types of construction.

' I realize -that considerable variation is possible in the .details of construction of my improved' device, without i departing from the spirit of my invention, and I do not intend therefore'to limit myself to t-he specific form herein shownand described.

What I claim as new, and desire to secure 1. The combination with a conveyeriand a discharge-'slide at" the end thereof pivoted between its ends whereby-its upper end can project into the path Jof articles on the consuch articles may elevator' the discharge-slide in their passageto per slide being adaptedl to support the articles while passing from the conveyer to the ele# vator. l

2. In combination,` a conveyer, a discharge-slide pivoted between its ends adjacent to the end of a conveyor whereby its upper end can project into the path of articles-'upon said com-'eyer, an elevator-chain provided with flights disposed beneath the discharge-Slide, the flights being arranged to contact with the discharge-slide to elevate the same, depressing the upper end thereof to release packages moving upon the conveyer said dischaigey slide being adapted to 'support the articles while passing from the conyeyer to the elevator.

3. The combination with a conveyer and an elevator adjacentthereto, of a dischargeslide swingingly connected to said convey-'er and adapted when in lowered position to forma stop to retain articles thereon and when raised to form an incline down which travel to the surface of, the elevator. g

4. In combination, an inclined elevator for conducting packages upward and a conveyer inclined downwardly from a point ad- -jacent the upper end of the elevator, said elevator comi-rising l package-supporting 4sel'iarated flexible members free at their for- "ward ends. forming a slatted platform adapted to extend outwardly in the plane offthe downwardly inclined conveyer at the curve 0f the elevator'at its upper end, wherelby packages restinff on said flexible members are discharged fi'om the elevator to the conveyer without substantial tilt or j ai'.

- 5. In combination, an inclined elevator for cond-noting packages upward and a conveyor inclined downwardly from a point adjacent the upper end of the elevator, said comprising package supporting separated flexible members free at their for-V ward ends forming a slatted platform adapted to extend outwardlyy in the plane of the downwardly inclined conveyer at the curve of the elevator at its upper end and to partially bridge the space between the elevator and conve-yer, whereby packages restin on said flexible members are discharged rom the elevator to the conveyer without substantial tilt rjar.

6. In combination, elevator chains guided to travel lirs; in a substantially horizontal and then in a diagonally upward direction for the elevation of packages, flights carried by the chains, and intermediate flat package-carrying members mounted at their rear ends-on one link only of each chain and free at their forward ends, whereby said package-carryinor members afford elastic carriers for the pac 4ages and are adapted to conformto the curve of the elevator chains at yward at an angle, flights lcarried by the respective ends of the traverse of said chains, as set forth.

7. In combination, a cha-in guided to run first in a horizontal and then in anupwardi'y inclined plane, flights carried by the chain, a pair of cross-bars extending between the chains, a series of longitudinally-extendin' Hat-fingers carried by the rear-cross-bar an arranged to be supported by the forward cross-bar.
