NUT FOR SCREWS.

Application filed November 23, 1923.

lTo all whom t may concern.'

Be it known that l, SAMUEL J. NoLL, a citizen of the United States., and a resident of Newark, county otfEsseX, and State of New Jersey, have invented certain new and useful Improvements in Nuts for Screws, of which the following` is a specification.

This invention relates to an limproved device for receiving screws that are` fitted to holes too big for them and by acting,- as a nut causing a binding` on the screw that allows it to be again brought up tight against the element it is intended to secure.

rIhe invention illustrated and described as applied to a hinge plate on a door 'Frame although it will be evident that it applicable to many different situations and applications,

The invention is illustrated in the accompanying` drawings in which Figure 1 is a section with the device in place and `lligurs 2 is a section on line 2--2 in Figure 1. Figures 3, and are views similar to Figure i showing the manner of inserting the device. Figure 6 is a perspective view oi? the device.

The article is a plate 10 usually of steel with a pointed end 11 to permit its being easily driven through a board and near the pointed end is a perforation 12 this perforation beinpv usually screw-threaded.

l illustrate the device as used in a cone ventional door frame comprising a board 13 secured to a board 14- and the hinge 15 is shown as having` the leaf 16 secured in place by the screws 17. ln cases where the door is frequently removed and replaced as in the case of a screen door the screw hole 1S soon becomes enlarged and worn so that the lscrew no longer holds and cannot be tightened. In such case the plate 10 lis driven Serial No. 676,494.

in by a hammer, shown partly at 19 at right angles to the hole 18 until the hole 12 can be seen through the hole 18 as substantially aligned therewith. In the case of wood screws an approximate registering is sutlicient as when the screw 17 is inserted the pointed end of it enters the hole 12 and causes the plate 10 t-o be slid into exact position. The hole 12 is small so that the screw 17 enters it and engages its sides and 50 the plate acts as a nut and the screw can be screwed up tight.. To allow for a flush appearance for the tail of the plate 10 after it is in placel the plate is weakened at spaced intervals and I show, for this purpose, the parallel depressions 20 which form weakened portions. W'hen the projecting` part of the plate (see Figure 4) is to be removed it is tapped with the hammer and the plate broken off at the weakened part close up` in the wooden structure and is substantially flush as in 'Figure 5.

With this device in place repeated removals of the screws can be accomplished without affecting the fit on subsequent in* sertions.v

l claim:

1. A, nut for screws comprising a iat plate having a pointed end and a screw-threaded perforation near said end.

2. A nut for wood screws comprising' a flat plate with a pointed end and a perforation near said end, the other end of the plate having weakened portions to define lneakin, l points on said plate.

l'n testimony that l claim the foregoing. l have hereto set my hand, this 21st day of November, 1923.

SAMUEL J. NOLL.
