BOX-NAILING PRESS- Specification of Letters Patent.

Patented Jan. 1 5, 1 907.

Application filed January 16, 1906. Serial No. 296.421.

To all whom it may concern.-

Be it known that we, HENRY A. BASSFORD and GEORGE S. BASSFORD, citizens of the United States, residing at Vacaville, in the county of Solano and State of California, have invented new and useful Improvements in Box-N ailing Presses, of which the following is aspecification.

Our invention relates to a device for use in nailing covers on fruit and other boxes.

In packing apples, pears, and the like for the market the box is filled so that the contents extend more or less above the edges of the box. The covers are usually th in boards, and they must be pulled down tight at their ends to enable them to be nailed to the ends of the box.

The object of our invention is to provide a simple practical press for pulling down and holding the ends of the covers, so that the latter may be nailed, which press is adapted to boxes of all sizes and which will automatically release a box on the release of pressure.

It consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a perspective view of the press, and Fig. 2 is a side elevation of a modification of the same.

A represents a frame or table of any suitable description. On the top of this table are the angle-iron or equivalent guides 2 for centering and holding the box which is to be covered.

Suitably arranged below the table is a vertically-reciprocating carriage 3, preferably constructed of ordinary pipe-fittings with suitable offset T members 4, sliding on the vertical guides or standards 5. Springs 6 act to move the carriage 3 normally upward toward the top of the table. The carriage is reciprocated in opposition to the springs 6 by suitable means, as the foot-lever 7, which is fulcrumed, as at 8, and is connected to the carriage by the link 9. The carriage may be held at any suitable level by engaging the dog rojection 10 on lever 7 in the rack-teeth 11, ormed on the inside of the guide-straps 12. The carriage 3 supports the bails 13, by which the ends of a cover are drawn down snug onto the ends of the box.

A bail 13 may be made from a fiat metal bar bent into suitable shape so as to extend down on each side of the table A and to pivotally connect, as at 14, to the carriage. The upper horizontal'portion of the bails may be twisted at their angles, so as to lie in planes substantially at right angles to the planes of the legs of the bails, thereby affording a suitable stiff straight edge to bear equally across the entire width of the box.

The legs of the bails may be of any suitable length, and they may be perforated, as at 15, to enable their pivots to be shifted to lengthen or shorten the bails, and so accommodate the device to boxes of any desired depth. As the bails are freely turnable toward and from each other on their pivots, they are capable of taking boxes of any length. The movement of the bails away from each other may be limited by suitable means, as the stops 16.

In practice the bails are adjusted on their pivots on the carriage 3 to allow the bails to project the proper amount above the top of the table, depending on the depth of the box to be nailed. WVith a deep box the bails are pivoted nearer their ends than if a shallow box is to be handled. The box to be nailed is placed in its seat 2, the cover laid on the box, and the bails turned inward to stand with their horizontal portions slightly inside of the planes of the ends of the box. The foot-lever 7 is then operated to pull down the carriage 3 and engage the bails with the ends of the covers to properly clamp the cover for nailing purposes. A slight lateral movement of the lever 7 engages the dog 10 with the rack 11. The cover may then be nailed on, after which the foot-lever7 is released, and the carriage and bails lift automatically by reason of the springs 6. The bails are then thrown outward to release the box, which may then be removed and a fresh one inserted, the action being repeated indefinitely. I

In Fig. 2 we have shown a modification of the invention in which it is possible to adjust the bails to boxes of various sizes and to clamp the boxes Without having to handle or guide the bails by hand in any manner. In this case the bails 13 are pivoted to the carriage 3, similarly as before described; but they are longitudinally slotted, as at 1-7, to receive the guide-pins 18, which are capable of being adjustably secured in the holes 19, formed in the stationary part of the table. By engaging the pins 18 in the slots 17 and in appropriate perforations 19, depending on the length of a box, it is possible to have the bails so act when the carriage 3 is moved down for the horizontal clamping portions of the bails to come down in exactly the right position onto the cover and box. In this case the boxes are fed in from an end of the table and through a bail rather than from the side of the table and between the bails, as in the first instance. The springs 6 normally act to lift the carriage 3 and the bails 13 to allow the ready ingress egress of the boxes. By suitably positioning the fulcrum-pins 18 in the manner described pressing down on the foot-lever 7 the clamping horizontal l portions of the bails describe arcs which have their adjacent terminii slightly within the planes of the ends of the positioned box, leaving only enough of the ends of the cover projecting outside of the bails for the purposes of nailing.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. A box-nailing press comprising table, a carriage movable at right angles to the plane of the table, verticallyadjustable clamping-bails pivoted to the carriage and movable to and from each other, means for reciprocating the carriage, and shiftable means on the table and forming fulcra for the bails to turn about in the vertical movements of the carriage.

2. A box-nailing press comprising a table, a vertically-reciproeating carriage thereunder, clamping-bails extending across the ta ble and having their legs straddling the outer sides thereof, said legs being pivoted to the carriage, and said table having a series of holes, and pins removably fitting said'holes and forming shiftable fulcra for the bails to turn about in the vertical movements of the carriage.

3. In a box-nailing press, the combination of a table having suitable box-centering guides, a vertically-reciprocating carriage arranged below the table, said carriage cornposed of vertical and horizontal pipe-sections. clamping-bails extending across the table and down over the outer sides thereof and having their lower ends pivotallyconnected with the carriage, said table having a series of holes, pins removably fitting said holes and forming shiftable fulcra for the intermediate portions of the side arms of the bails, and means for reciprocating the carriage.

4. In a box-nailing press, the combination of a suitable box-support, a vertically-reciprocating carriage, bails extending across the support and pivoted to the carriage, said bails having longitudinal slots, and adjustable pins fitting said slots, and carried by the support and forming fulcra for the bails to turn about in the vertical movements of the carriage, and means for reciprocating the carriage.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
