Figur 1-is an enclosed casing ment 2 having a compartand an upper compartment?) separated from the firstnamedcompartment by a glass partition 4. 5'is'a cover hinged at its upper edge at 6 to the casing 1 and adapted to close the otherwise open front of partment 2.

casing 1 partment 3. 7 is a glass plate clos-' otherwise open front of the com- 9 is a slot in one end of the through which the glass plate? may be introduced, its inner edge engaging in a slot'9 in the opposite end wall of the casing 1. 8 is a cover screwed upon the end wall of 10 (Fig the casing 1 to cover the slot 9. 10,

. 2) are lamps in the compartment 3.

11, 11 are supporting end plates extending parallel to each other and'to the end walls of the casing 1 and adjacent to said walls.

17 1s a sectional'rod' having a turn-' line 111, 111' buckle 1" and extending between the plates 11, 11; 12 is a roller'pivoted at its ends in the plates 11, 11, and provided with attaching pins 12, 12 13 is a roller pivoted at its ends in the'lower portion "of the plates 00 11, 11, entirely similar to the roller 12 pivot ed towards the upper ends of said plates. 13 13 are attaching pins extending from the roller 13. 12 is a squared extension of the shaft of the roller 12 and 13 is a similar extension of the shaft of the roller 13. 16 16 (Fig. 1) are holes in the end wall of the casing 1 through which a key may be passed to engage the squared extension 12'' or 13 to rotate the roller's12 or 13. 14, 14 are ratchet wheels upon the shaft of the roller 12 outside of and adjacent to the plate 11., 15, 15 are similar ratchet wheels on the ends of the shaft or' the roller 13. 14 is a pawl adapted to engage the teeth of theratchet wheel 14. There is a pawl 14 engaging each of theratchet wheels 14 and between the pawls extends a rod 14 by which said pawls may be simultaneously raised to disengage this from the teeth of the ratchet wheels 14, 14. i There is a pawl 1'5? adaptedv to engage the teeth of each of the ratchet wheels 15, 15. v

The number of the automobile is placed upon a sheet of paper or other suitable mate'rial. of the shap'e'shown in Figure 5, in which 16 denotes the number sheet and 16 theenga'ging apertures in the upper and lower portion of said sheet. Said engaging apertures are placed over the pins 12 and 13 and the rollers 12 and 13 turned in opposite direction untilthe sheet is drawn taut and is held, asshown'in Figure 4, converging outwardly from the top to its lower portions and in front of the glass plate 7 so that the number may be seen through said plate and'will be illuminated by the light from thelamps 10,10'in the upper compartment 3.

18 is, arotatable shaft pivoted at its ends in the plates 11, 11 andlocated between the rollers 12 and 13 and parallel thereto. 20, 20 are ratchet wheels on the axle of the shaft 18 and 21, 21fare pawlsengaging the teeth of the ratchet wheels 20, 20; 19, 19 are spiral springs adapted to rotate the shaft 18. 18

is a squared shaft which may be engaged by a key passing through the hole 18 in the end of the casing 1, to wind up the springs 19, 19, which springs are held in their wound up condition by the pawls 21, 21 engaging the ratchet wheels 20, 20 and when said pawls are released. the said springs unwind, rapidly rotating the shaft '18. 18 is a series of cutter bars extending at right angles, or radially, from the shaft 18 and arranged in a spiral extending about half way around the shaft. The shaft 18 is arranged, as shown in Figure 4, so that the sheet number 16 will clear it but the bars 18 will strike against and out said sheet into strips and destroy the number thereon when the shaft 18 is rotated.

23, 23 are tubular guides extending vertically and secured to the bottom of the easing 1 inside and towards the ends of said casing. 25, 25 are tubular parts fitting over and adapted to slide on the guide 23 and preferably having their upper ends closed. 24:, 24 are helical springs in the guides 23, 23 acting to force the parts 25, 25 upward when said parts are free to move. 25, 25 are horizontal extensions from the lower ends of the parts 25, 25.

26 is a rod extending horizontally between the plates 11, 11 and adapted to reciprocate backward and forward in slots 27 in said plates. 26 is a rod extending horizontally forward from the center of the rod 26 and passing outward through an aperture in the front of the casing 1. 26 is a roller adjustably supported below the rod 26 and rigidly secured to said rod. There is a roller 26 at each end of the rod 26, when the rod 26 is pulled forward the rollers 26 come over the extensions 26 of the parts 25 and hold said parts in their lowest position with the springs 24. contracted. When said rod is pushed backward, as indicated in broken lines in Figure 1, the rollers 26 are'removed from over the extensions 25* and the parts 25 are free to move upward under the impulse of the springs 24: unless otherwise restrained.

22, 22 are rods extending vertically downward, pivoted at their upper ends to the pawls 21, 21 and extending at 22 over the extensions 25 of the movable parts 25.

The glass 7 is cut away at 7 7 (Fig. 6) so that if said glass is moved endwise until such cut away parts come over the parts 25 the last named parts will be freed from the restrain of the glass 7 resting upon their upper edges and permitted to rise under the impulse of their springs 24, 2 1-.

33, 33 are tubular guides extending from the rear wall of the casing 1 and having helical springs 31, 31 therein. 28 is a bolt having a head 30. The shank of the bolt 28 passes through the spiral spring 31 and through the guide 33 and through an aper- Thearts 25 are forced downward and i are engaging rod 26 is drawn forward so as to hold the parts 25 in their lower positions and the springs 19, 19 are wound up,

the shaft 18 being in the position shown in Figure 4:. The sheet 16 is now engaged by the aperture 16 over the pins 12, 12 and 13, 13 and the rollers 12 and 13 are turned to tighten said sheet. The casing is attached to a convenient support by the bolts 28 and said bolts are drawn up to considerably contract the spring 31 and even so that the head 30 of the bolt shall engage the end of the guide 33, thus holding the casing in position to show the number through the open front of the casing. The glass 7 is now slid inward through the opening 9 and rests with its lower edge upon the parts 25, 25.

The engaging rod 26 is now pressedinward by means of the rod 26 until the rollers 26 are free of the parts 25 and the rod 26 falls inside the casing. closed by securing the covering plate 8 thereon.

Now should anyone attempt to remove the number sheet he might take off the cover plate 8 and draw the glass 7 outward in the slot 9. If, this were done, when the cut away portions 7 7 came over the parts 25, 25 said parts would be forced upward, the

extensions 25 would engage the lower ends of the rods 22 and force the pawls 21, 21 out of engagement with the teeth of the ratchet wheels 20, 20 releasing the shaft 18, which would be rapidly rotated by the springs 19, 19 thus by means of the bars 18? cutting the sheet 16 into shreds and de.

stroying said sheet and the number thereon. Should the plate-7 be broken and removed of course the same result would follow.

Should an attempt be made to remove the casing 1 entirely by unscrewing the nuts 29 or cutting the bolts 28 said bolts would be released and the springs 31 would force them forward carrying the rollers 35i'nto contact with the pawls -21 releasing'thze shaft 18, as before described, and destroying the number sheet.
