PORTABLE NAIL STBIPPEB.

Application filed October 1, 1928. Serial No. 309,455'.-

The invention forming the subject matter of this application relates to foldable nail strippers, and particularly to foldable devices which automatically arrange a bunch of nails dropped thereon in single file, so that the same may be withdrawn by the carpenter using the nails to occupy the correct position between his fingers for immediate use.

The primary object of the invention is the provision of a foldable nail stripper which is readily carried by a carpenter so that the same may be placed alongside the place where the carpenter works, and which may be readily set up into operative position and is supported in such a manner that each blow struck by the carpenter with his hammer vibrates the supporting members on the whole nail stripper, thereby advancing the nails into the correct position, readyto be removed for use by the carpenter.

Other objects of the invention are to provide a portable and foldable nail stripper that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation and facility, convenience in use, and general efilciency.

In this specification, and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the drawing:

Figure 1 shows a perspective'view of the nail stripper set up for use;

Figure 2 is a sectional view of the nail stripper in a folded position inside of the casing in which it is carried; I

Figure 3 is a fragmentary, detailed view showing the manner in which the brackets of the nail stripper are supported so as to render the same portable at will; and

Figure 4 is a fragmentary view of the joint securing of the brackets to a support, showing the joint in the folded position of the bracket.

Referring to the accompanying drawing, wherein similar reference characters designate similar parts thruout, the various figures described above adequately illustrate my invention, and the following detailed description is commensurate with the above 55 mentioned drawing in enabling an artisan to construct and assemble the constituent parts of the same.- a c In carrying out my invention, the stripper 1s arranged in a case, denoted in its entirety by the numeral 1, which case is made'in the form of a suit case and is made preferably of wood. The two halves 2 and 30f the case. 1 are hinged as at 4, and are provided with suitable catches 5 for closing the same. From the bottom 6 of the case rise two brackets 7, the lower ends 8 of which ares'ecured to the bottom '6 by means of bolts and nuts 9. Abolt 11 extends thru the upper end of each bracket. 7. The brackets 7 are so formed that they incline toward the adj acent end wall of the case 1. To the upper ends of the brackets 7 are secured standards 12. The standards are so shaped that the lower portion thereof ex-. tends in extension of the brackets 7, and the uppermost portion thereof extends substantially vertically. In the lower end of each standard 12 is cut a square slot 13, which terminates toward the lower end of the standard 12 in a round aperture 14. It is to be noted that the portion of the bolt 11 which extendsv thru the slot in the lower end of the standard 12 is provided with oppositely'disposed flat surfaces 16, which surfaces are inparallellsmv with the direction in which the brackets 7' slope. 1

It is apparent that when the standards 12 are disposed in the manner shownin Figure 1, they lower by their own gravity so that the square slot 13 slides over the fiat faces 16 of the bolt 11; thus the standards 12 are sup-j ported in an upright'position and are pre= vented from pivotal movement upon the bolt. 11, The standards are folded onthis joint" by pulling the standards 12 upwardly until the round aperture 14 is raised in a position surrounding the bolt 11, whereuponthe lower end of the bracket may beipivoted around the bolt 11 so as to assume the folded posi-: tion within the case as shown in Figure 2 To the upper ends of the standards 12 is secured a box 17 in themanner shown in Fig ure 1. The ends of the standards12-are secured to the opposite sides of the box by means of bolts and nuts 18, the ends of the standards being spaced and reinforced by a substantially U -shaped cross member 19,'the legs of said U-shaped member 19 extending between the sides of the box 17 and the upper ends of thestandards 12. The box 17and the U-shaped member'19 are pivotally supported on the nuts and bolts 18 so that the same may be folded alongside the standards 12, whereby they areallowed to assume the position shown in Figure 2.

The lowermost end of the box 17 is open so that a bunch of nails thrown'in the box will work downwardly, particularly when the standards 12 are set into slight swinging or vibrating motion by the handling of a hammer in the immediate vicinity. The box 17 is disposed at sucha slant that the nails advance over the lower edge of the box, wherefrom they drop upon a guide 21, which guide consists of aplurality of V-shaped troughs 22 with open bottoms so as to form slots, allowing the shanks of the nails to drop therethru while preventing the heads from doing so.

The troughs 22 are arranged to slant downwardly from the lower end of the box in a reverse direction. The troughs communicate at their lower ends with sets of rods or rails 23 arranged so as to continue the slots in the troughs and to allow the heads of the nails to ride downwardly therefrom. The upper end of the guide containing the troughs is secured to the lower end of thebox by means of hooks 24 which are pivotally supported in the sides at the lower end of the box 17, and are so bent as to be readily inserted in corresponding apertures in the upper end of the guide 21.

The lower ends of the rodsor rails 23 are fastened to a metal strip 26, the ends of which are bent. at right angles so as to form a U-shaped strip with comparatively short legs 27. The legs 27 are pivotally supported on the standards 12 by means of bolts .and nuts 28. The folding of the guide member ii performed by removing the hooks 24 from t e that the guide 21 drops by its own gravity, pivoted around the bolts and nuts 28 and assumes the position shown in Figure 2.

In therods an offset 29 is formed near the joint with the troughs 22 in the manner de-- scribed in my Patent #1,677,527, dated July 17 1928. Theseoffsets'provide stepsin the rods and allow nails suspended from the rods to be withdrawn therethru. In order to reinforce the structure without materially reducing its resiliency, the brace 19 carries a hook 31, while another hook 32 is secured in a co-acting position with the hook 31 on the outside face of the corresponding side of the half 2 of the casing 1; A spring 33 is stretched between the hooks 31 and 32, the opposite ends thereof being removably. supported on the hooks. A shield 34 is provided so as to be readily positioned opposite the end of the rails 23 and outside of the stand ards 12 so as to prevent the accidental falling of the nails out of the case 1.

A guard rail 37 extends transversely over the rails 23, and is spaced therefrom so as to allow the passage of the nails thereunder.

guide 21, thereby releasing the same so.

rightposition. The box 17 is then turned around the pivots 18, the slope of the box 17 being determined by the position of the upper edge of the guide 21. The guide 21 is turned around the bolts 28 until the ends of the hooks 24 are in cooperative position relative to the corresponding apertures in the guide 21. When the hooks 24 are secured to the upper end of the guide 21, the slope of the box 17 and of the troughs 22 is determined thereby. Now, by securing the spring 33 upon the opposite hooks 31 and 32, the structureis strengthened in. its upright position. Then the shield 34is placed behind the lower end of the brackets 12, and the device is ready for operation.

The device is used in the manner described in-my aforesaid patent, the operator dropping a bunch of nails on the box 17, which nails are guided thru the troughs 22 and rails 23 and are disposed in a long line, depending on their heads from thelower rails The whole line may be removed thru the'loop formed at'the offset 29.

When the device is not in use,'it may be readily folded by first releasing the spring 33 and placing the same on the bottom of the half 2 of the casing 1, in the mannershown inFigure 2. Next, the shield 34 is removed and it will beplaced in the, upper half 3 of the casing l after the device is folded. The next step is the releasing of the books 24 and the dropping of the side 2l-to the bottom 6 of the half 2. 'A trough shield 36, which depends from the bottom'of the box 17 over the V-shaped troughs 22, is pivotally secured to the bottom of the box 17, so that the same may be folded over the bottom of the box 17. Then the box.17 is pivoted around the bolts 18 over the standards 12. The standards 12 are then raised-until theround' aperture 14 in the lowerends thereof surround therespective bolts 11, whereupon the standards 12 are pivoted around the bolts 11 sothat the box 17 may rest upon the guide 21. It is to be noted that the box 17 and the guide 21 are so proportioned that the guide 21 fits within the box 17 when the device is folded. Now, the shield 34 is placed in a corner of the upper half 3 of the case 1 in the manner shown in Figure 2. In this position, the compact unit is. folded in the lower half of thebox. Then, by closing the case 1, the same may be readily closed'by the hooks and forms a I readily operating when set up, also combines strength with facility of transportation. The device maybe readily set up, and when in position, it combines vibratory operation with a ruggedness of construction adapting the same for its use. The device does not require any careful adjustment and readily lends itself to effective application by the labor ordinarily available.
