BURTIS VAN HENNIK, OF NEV YORK, N. Y.

PAC KAG E- SPECIFICATION forming part of Letters Application filed August l, 1890.

.To all whom t may concern.-

Be itknown that l, BURTIS VAN HENNIK, of New York city, in the county and State of New York, have invented a new and Improved Package-Elevator for Presses, of which the following is a full, clear, and exact description.

My invention relates to a package-elevator for presses, and has for its object to provide a means whereby packages of paper to be printed may be expeditiously and conveniently elevated from the Hoor of the pressroom and delivered alongside of the feedtable of the press with a minimum of inconvenience to the attendants of the press; and a further object of the invention is to provide a means whereby the elevated packages may be readily transferred from the elevator to the feed-table.

Another object of the invention is to provide a device capable of accomplishing the above-named results which may be set up in any press-room, occupying space not heretofore utilized, and to so simplify the device that it may be construct-ed and erected at but little cost and attended by unskilled labor.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the elevator, the lifting-platform being represented as in position to receive a package. Fig. 2 is a perspective View of the elevating mechan ism, the elevator being illustrated as carried upward and the package as in position to be slid upon the feed-table; and Fig. Sis a transverse section through the elevatortab1e and its carrying-frame, illustrating the said table in position to admit of the transfer of the paper to the feed-table. i

Tracks 10, usually two in number, are suspended from the ceiling or other support at the rear of the feed-table 11 of the `press or presses, which tracks are inclined downward at one end in the direction of the table, as is ELEVATO R.

Patent No. 449,453, dated March 31, 1891.

Serial No. 360,695. [No model.)

best illustrated in Fig. 2. The tracks may be of any desired contour in cross-section, and upon the tracks a carriage A is held to travel, which carriage consists, preferably, of four corner posts or uprights 12, connected by cross-bars 13 and braced by diagonal bars 14. Each of the corner posts or standards has formed integral with its lower end or attached thereto a hook 15, the mouth of the hooks being somewhat diagonally inclined, as is best shown in Fig. 1.

each of the corner posts or standards of the carriage a friction roller or wheel 1G is journaled, which wheels. are adapted for engagement with the tread of the track, the said wheels or pulleys being usually provided with a peripheral groove to receive the same..

To the forward end cross-bar of the carriage one end of a rope 17 or chain is secured, the attachment of the chain being preferably at the central portion of the said end, and the said rope or chain is carried for ward between the tracks to a point at or near the ends of the latter and downward over a friction-pulley 18 or equivalent device pivoted in any approved form of hangen, and

chain is carried vertically downward and attached to an eye 19 or its equivalent secured to the floor of the press-room, for instance. The said cord or chain is also preferably provided with a ring or eye 20, secured thereto between the friction-pulley 1S and its lower attached end.

At or near the forward or upper end of the tracks a drum 21 is pivoted in suitable bearings 22, the said drum heilig' preferably made to extend transversely below the tracks. The drum has integral with or attached to one end a peripherally-grocved wheel 23, and to the periphery of the said wheel one end of a rope 24. or chain is secured, the other end of the said rope or chain being attached to a windlass 25 or its equivalent, as illustrated in Fig. 1; but, if in practice it is found desirable, the rope or chain may be passed around the wheel 23 of the drum, and thence around a lower friction-pulley, in which event the chain or rope is endlessl Near one end of the drum two cords a and from the friction-pulley 18 the cord 17 or- In suitable bearings at the upper end of IOO a or chains are secured, and at or near the opposite end two other cords a2 and a3 are secured. The cord a or chain passes through screw-eyes and over friction-rollers 26 and 27, somewhat closely grouped and secured to the ceiling or other support to which the tracks are attached, and afterpassing over the innerfriction-pulley 27 the cord a or chain is permitted to fallvertically downward. The second cord d orchain of this pair is also carried overfrictionrollers 2S and 21), suspended from the ceiling; but the friction-roller 29 is a much greater distance from the friction-roller 2S than the friction-roller 27 is distant from the friction-roller 26. Afterpassingoverthe friction-roller29 the cord c or chain is also permitted to drop perpendicularly downward. The cords a2 and as or chains are passed over friction-rollers in like manner to the cords c, and a at the opposite end of the drum, and which have just been described, the position of the frictionrollers over which the rope a2 or chain passes corresponding in position to the friction-rollers 26 and 27 of the cord a or chain, and the friction-rollers of the cord a3 or chain correspond in location to the frictionroller 28 and 29 of the cord ct or chain.

The lower extremities of the cords c, a', d2, and a3 or chains are attached one at each cornerof a platform 30, which platform, together' with the cords, constitutes an el@ vater B. The platform 80 is preferably made as light as possible consistent with strength, and in the drawings is represented as constructed of two side bars having eyes formed at their extremities, through which the cords or chains are passed, the said side bars being connected by diagonal brace bars, as is best shown in Fig. 2.

In connection with the elevator and carriage a paper-carrying table C is employed. The table is preferably made in two sectionsnamely, a platform-section 3l and a framesection 32, the former being fitted into the latter. The frame-section corresponds in contour to the contour of the platform-section, which is preferably rectangular, and the frame-section 32 is ordinarily made of skeleton form and provided at each corner with an upwardly-extending preferably perpendicular standard 33, each of which standards is provided at or near its upper extremity with a longitudinal slot 34. Then the elevatorplatform B is constructed as described, the side bars of the frame-section of the table are provided with recesses to receive the transverse bars of the elevatorplatform. rlhe platform-section 8l consists, preferably, of one piece of metal, wood, or other preferred material, and is usually divided transversely into two compartments bya partition 35. At one side of the platform-section of the table and at both ends upright studs 3G are secured to the upper face, as bestshown in Fig. 1, and at that side of the platform-section which faces the press feed table or tables studs 37 are located, which studs are preferably latter.

hinged or pivoted to the platform-section in such manner that they are capable of folding downward and outward, as shown in Fig. 3. The construction of the movable studs, as illustrated in the drawings, consists in providing the inner end of each stud with a longitudinal slot 3S, and the studs are locatedin metal-lined recesses 39, the. pivot-pin of the studs being secured in the walls of the recesses and made to pass through the slots 38, as is likewise best shown in Fig. 3.

In operation the table C, seated in its frame, is placed upon the elevator-platform B when the said platform is resting upon the floor of the press-room, and when the table is in this position the desired number of packages ofpaper to be printed are placed upon it. The carriage A is then drawn up the inclined tracks until it is near3 the forward end of the Then the carriage is in proper position, it may be held so by causing the ring 2 0 ofthe rope 17 or chain connected with the carriage to engage with a hook or equivalent device placed in the floor to receive it, as illustrated in Fig. 1, and when the carriage is secured in proper position it will be immediately above the table, as shown in the same ligure. By operating the windlass or the cord 24, connected with the drum 2l, the said drum is revolved and the lifting-cords c, a', a2, and a3 or chains are wound upon the drum, and the elevator is thereby carried upward beneath the carriage. As the elevator-platform approaches the carriage the slots 34 in the uprights 33 of the table-frame receive the hooks 15 of the carriage, whereupon the frame and table become a portion of the carriage, and by loosening the rope 17 or chain the carriage is permitted to travel down the inclined plane of the tracks untilit reaches one of the press feed-tables, as illustrated in Fig. 2, at

which point it may be stopped in any suitable or approved manner, and the pivoted studs 37l are thown downward upon the presstable, as shown in Fig. 3, and the operator'at the feed-table may thereupon expeditiously slide the packages of paper from the table of the carriage to the said feed-table. Then the packages have been delivered to thepress or presses, the cord or rope 17 is again drawn downward and the carriage is brought over the elevator-platform. The windlass is'then operated, and the platform of the elevator is lifted upward sufficiently to engage with and elevate the frame carrying the platform-section of the table C, and in thus lifting the frame the slotted standards of the latter are disengaged from the hooks of the carriage, and in disengaging the standards cause the carriage to slide slightly forward as the tops of the standards come into engagement with the inclined surfaces of the hooks, and by pushing the carriage a slight distance forward it is removed from the path of the table C, whereupon the elevator may-be lowered to carry the table with itto the floor of the pressroom to receive another load.
