Romains, a in the torni or t-restle provided with pairs citizen oi the United States, residing at Wilot upright guides 2 at opposite ends with ton, in the county of Hillsborough and State the guides appropriately spaced apart to 5 ot New Hampshire, have invented certain ccive between nach of them a slide member 3 C0 new and use 1ul improvements in Box-Cover oi? appropriate length. These slide members Presses, of which the following is a speciare joined by cross members 4, 5 and S, rciication. spectively, the member 3 serving as a sup This invention has reference to box cover port for a box or container T desio'ned to conpresses and i155 Object is to provide a device tain fruit or vegetables, while the cross piece 65 whereby a boxY cover may be subjected to 4 joins and participates. in the movement of pressure to hold it positively in position on the SllGS 3. the box during the nailing of the cover there The Cross pieces 4 and 5 are joined by a on. coiled spring 8 tending` to cause the slides 5';

Referring to the drawings, there is shown causing a participation ci the toggle in the eil movement ot the toot treadle Q0 or with the spring 8 as the case may be.

Then the box is mounted on top of the trestle and the follower 6 is brought into Contact With the cover l0 of the box, the structures are firmly united und the nailing of the Cover in place may proceed, after Which the yoke structure 20 is raised there-- by breaking,- the toggle connection 10a, ll, and allowing the spring' S to act to raise the slide 3 and elevate the follower G automatirally.

The action ot the box clamping structure may be rapid and certain, with the follower 6 locking in the depressed position und the toggle holding the follower during the process o nailing the boX Cover.

'What is claimed is l. A box cover press comprising a support for the box, slides on opposite sides ot the support, pairs of guides outside or" the support, with a slide between each pair ot guides, a. follower connected to and participating in the movements ot' the slides, and a toggle actuator for the slides.

2. A box @over press comprising a support for the box, slides on opposite sides of the support, pairs of guides outside of the support, with a slide between each pair of guides, 'follower connected to and` partieipatinfc)` in the movements of the slides. and a toggle actuator Yfor the slides, said `guides and follower having associated with them un extension spring tending to hold the toggle actuator in the lextended or looked position.
