of the lower truck a of the movable carriage. lhbraclrct 71 extends iromfthelower truck under the bar that carries the rib Z and also serves as a guide for the lower To all whom it may concern:

Be It known that we llrnsnn'r l3. Buss United States, residing at Detroit, county of l Vayne, State of Michigan, have invented a k as it r ns along the rackl' rom the certain new and useful linproveinent in a above, it is evident that the lower truck can I l forlr l able for a Machine for Driving Me travel toward and away from the upright of tallic Fasteners, and declare the following to the machine. Upon the lower truck is carhe a full, clear. and exact description of the ried a track q and another track r. The same, such as will enable others skilled in the track 9 is provided with a rib while the track 1" is preferably smooth. The grooved wheel .9 of the upper truck at fits onto the ribbed track (7 and the brackets u on each side extend under the lower truck edge to form guides. It is therefore evident that the upper truck 13 can be run transversely of the lower truck.

o is a screw journaled in tic brackets to of the lower, truck. A pair of nuts to run upon this screw. Consequently when the. screw is turned the nuts either advance or re treat from. each other by reason of the screw o being right and left hand. These nuts .1:

art to which it pertains to make and use the same, reference being had to the accompanying drawings, which. form a part of this specification.

This invention relates to work tables for moving fiber shipping cases which are sealed by wire stitching or metallic fasteners driven into the flaps at the end of the cash.

lln the drawings, Figure 1, is a side elevation of a wire stitching machine and the Work table. Fig. 2, is a plan view of the arm or rack which carries the movable carriage. Fig. 3;, is a plan view or the lower truck of the carriage. Fig. 4, is a plan viewed: the swiveling plate on the upper truck. Fig. 5, is a vertical section sl'rowing the pivot upon which the swiveling plate swivels. Fig. 6, shows the hall and spring interlocking which looks swiveling" plate in given positions with respect to the carriage.

The head of the wire stitching machine is desisnated a and need not be described as mac llll'E-S of this character are well-known in the art. The upright F) which supports the stitching head is in form of a cy i'idrical column s shown in l The sleeve pcrno large nut guided upon this The threaded portion the nut enga es rith the screw 03 .xlloh has a gear c on upper end that is revolved. by the worm f that in turn is rotated by the crank handle 7. It is evident that when the crank handle is turned the nut 0 will travel either up or down depending upon. the direction of revolution of the crank handle.

The nut c has at one side a vertical slot l"- shape in cross-section. This is indicated at it, l into this fits the 'l -bar end i of the arm 7'. This arm j is shown in a plan view in Fig. 2 and comprises not only the arm proper but also a rack 10 formed of two longitudinal bars and three cross bars. as shown iii-Fig. 2. One of these longitudinal bars the rack is provided with a raised the wheels 8. Consequently by adjusting the nuts to the desired positionthe stopping place of the carriages, when run in either direction, may be determined. These stop ping places are determined in reference tothe position on the flaps where it is desired to run the row of stitches.

ll. pair of plates 7 is mounted upon the swiveling plate 3 and can be moved transve. ely of the some by reason of the slotted bracl-rct arms which are held to the plate hy the winged. screws 1,. The rear end of the plate is provided with a cross plate or angle iron which limits he moven'icnt to the rear of the case when toe case placed. upon the swiveling plate 3. The swiveling plate 3 is connected with the upper truclr t by the pivot 4. The underside of the swiveling plate is provided with four slight depressions 5 which are located upon a determined circle so that in swiveling these depressions will pass over the spring ball 6 so that a weak temporary lock is effooted to notify the operator that one of the four positions in the turn of the swivelinn plate has been reached.

The operation of the apparatus is as follows: The carrier is drawn out to the end of the rack or arm; one of the plates 12/ is loosened and slid slightly to one side to allow the case to be shoved baclragainst the act as stops which engage with the axles of" rear plate 2 and the other plate 12 Whereupon the platethat has been moved is pushed against the case and held in this position by turning the winged nuts 1. The case is,

now adjusted upon the carrier, whereuponfready described, moves the entire arm by the screw and nut action. lVhen the proper height has been determined for a case of a given size, it will only be necessary to adjust the case upon the. carrier and then move the entire carriage forward. here upon the anvil will easily slip in under the flaps. The first row of stitches is taken in the two inner flaps (not shown) and the upper truck is forced over. against one of the nuts 0: so as to accurately determine the position of the first row of stitches in the two inner flaps when this row of stitchcshas been effected. Then the upper truck is forced over against the opposite nut and this determines the position of the second row of stitches in the inner row of flaps. It is evident that the distance of the stitches apart is determined wholly by the adjustment of thescrew '1) which determines the amount of separation between the nuts 02. Inasmuch as a blade-like anvil 7 is used, with large shipping cases it is almost impossible to seal the cases by a row of stitches clear across, for the blade-like anvil has not sullioient rigidity to extend clear across a case twenty or mpre inches wide. Consequently two operations are necessary. Two rows of stitches are inserted in the flaps fromone edge to the center; the box is then turned through 180 degrees, which is possible bv reason of the swiveling plate, and when the exact position of parallelism with irespect to the anvil of the machine is effected by reason of, the ball and depression lock, the carriageis swung back to bring the blade anvil 7 under the inner flaps at the opposite side; thereupon the two rows of stitches are repeated upon this side of the case. This seals the inner flaps.

It is customary in shipping cases to have two sets of flaps: inner and outer flaps; the inner flaps are continuations of two opposite sides while the outer flaps are continuations of theother two sides. Therefore the box is turned around through an arc of 90 degrees. to bring the anvil under the two outer flaps. Thereupon the operations enumerated in connection with the inner flaps are"repea'ted with the outer flaps until the box is completely sealed.
