To all whom t may concern Be it kn own that l, CHARLES W. Kami-inn, a citizen of the United States, residing at Zillah, in the county of Yakima and State of lVashington, have invented certainznew` Another object of the invention is to proi vide improved operating means for the clamp so that the clamp may be held in a lowered position while the lid is being nailed to the box and `to also provide improved means for guiding the vertical bars which carry the adjustably-mounted lid-engaging claws.`

This invention is illustrated in the accompanying drawings wherein Figure 1 is a side elevation of the improved press; Fig. 2 is a `vertical sectional view taken alongthe line 2-2 of Fig. l; Fig. 3 is an enlarged view of the upper-end portion of one of the vertical bars with the lid-engaging claw shown in place; Fig. 4l is a fragmentary view showing the treadle in section and the rack in elevation.

This press is provided with a supporting table which is provided with the corner standards 11 upon which the top 12 rests.

`'lhe forward standards 11 are connected by the cross bars 13 and 111 and the rear standards are connected by the cross bars 15 and 16 and connected with the forward standards by the angle bars 17 and side bars 18. The various parts which form the table are secured together by suitable bolts shown, and it 1will therefore be seen that the table will be very strong in construction and not liable to easily come to pieces or wear out. Angle bars 19 are carried by the table top 12, but are not securely held to the top since it is desired that these angle bars may be moved to accommodate themselves to the length of the box 20 which they support.

The treadle 21 has its rear end pivotally connected with the cross bar 16 by means of i the hinge 22 and has its forwardend portion Specification of Letters Patent.

passed the lower end of a bar24 which car- :ries a rack 25. A latch 2G is carried by the treadle and engages the teeth of the rack 25 `to releasably hold the treadle in a lowered position.` A. spring 27 has one end connected with the treadle by means of the eye `bolt 28 and has its upper end connected with `the'` table top by means ofthe eye bolt 2S).` This spring is provided to yieldably hold the treadle in the raised position shown in dotted lines in Fig.` 2. The rods 30 which are slidably mounted in slots formed in the table top have `their lower-end portions passed through the collars 3l and pivotally connected with the pivot pin32 which is` rotatably `connected with the treadleby` means of the bar 33. The collars 31 are adj ustably connected with the rods 30 by means of the setscrews 34 and are provided with eXtensions 35 so that the collars may be pivotally connected with the links 36. These links 3G have their outer-end portions pivoti ally connected with the pivot brackets 87 which are secured to the angle bars 17 as shown in Fig. 1.

The claws 38 are adj ustably mounted upon t the upper-end portions of the rods 30 and are releasably held in place by the set screws 39. Each of these claws comprises a sleeve 40 which carries the set screw 39 and forms a connecting means for the two arms 41 which extend in diverging relation from the sleeve, as shown in Fig. 3 and have their upper ends bent to extend beyond the ends of the box lid, as shown in Fig. 1. The upper ends of the arms are provided with en-` largedend portions 42 which provide means for firmly gripping the box lid and prevent any danger of the box lid being broken away when the treadle is moved downwardly.

The operationof this machine is as follows: The box 20 is put upon the supports 19 and the cover 423 is then put in place. The rods 30 are then moved to the proper position so that the claws 38 may engage the box cover and the claws 3S adjusted to the proper position and the set screws tightened. The treadle can `then be moved downwardly and this will cause the rods 30 to swing toward the center of the table until the claws engage the box cover and Patented Oct. 27, 19ML.l

provided with a slot 23through whichis i then move downwardly `to the position i ile the lowered position so that the operator can remove his foot from the `treadle while securing the cover with suitable nails. The treadle can then be moved to disengage the rack and the spring 527 Will then return the treadle and rods to the normal Position. It is, ofv course, obvious that the claws lWill have to be adjusted upon the rods 30 according to the size of the `boX and that the collars `3l are adjusted according to the amount it is desired to have `the rods 30 swing outwardly When the treadle is in the raised position.

lli/That is claimed is:

l. A press of the character described comprising a supporting frame, a treadle carried by said frame, rods pivotally connected with said treadle, article engaging means mounted upon said rods, and guiding means for said rods carried by said supporting frame and adjustably connected with said rods.

2." A press lof the `character described comprising a support, a treadle carried by said support, a pivot pin rotatably connected to said treadle, rods pivotally connected Wit said pin and extending above said support,` article engaging means carried by said rods, guides adjustably connected with said rods,

and links pivotally connected With said guides and with said support.

. 3. A press of the character described comprising a support, a treadle carried by said support and provided With a slot, a rack bar carried by said support and extending through said slot, a latch plate carried by said treadle and extending partially across said slot for engaging said rack bar, means for yieldably holding said treadle in a1 normal position, article-engaging means connected with said treadle, `and guiding means carried by said support andl adjustably con-V nected with said artcle-engagingmcans.

4. A press of the character describedv comprising a supporting frame, rods extending vertically throughy said frame, article-engaging means carried by said rods, collars slidably mounted upon said rods, means for releasabl holdinov said collars in an adjusted position, links pivotally connectedr `amies of thispatent may be obtained for ve cents each, by addressing the Commissioner of Patents,
