To @ZZ whom .it ,may conceive:

Be it known Ithat 1l, vJOHN A. MEHLING, a

citizen sof .the 'United States, and a resident and .exact `description, such as will enable others skilled in the art to Wh ichzi-t .-appentains 1o to make and use the same.

I choose to exemplify my invention in its application to a fare-collecting box for streetrailway service, a box having been selected having a sliding cover.

My invention consists lin the fixed hook upon the cover combined with engaging mech# anism upon the box,(` or vice versa,) which will act to pierce a paper check or seal which is out of reach of the conductor and must be 2o acted upon before the hook can be released therefrom or the cover can be opened.

My invention consists in the combination and arrangement of parts and construction of details, as hereinafter described, shown in A the accompanying drawings, and specifically pointed ont in the claims.

In the accompanying drawings, Figure l isa front view of the upper portion of the box, partly in section, showing the cover low-` ;o ered, and an edge view of the hook-engaging mechanism. Fig. 2 is a vertical transverse, section of the box, showing a side view oi'V hook-engaging mechanism and edge view of cover and hook. Fig. 3 is a top view of box,

Figs. 4t and 5 are viewsof paper check or seal. Figs. 6 and 7. are details of mechanism.

In the figures, l is the box-casing.

2 is the cover, which moves in grooves 3, arranged for it on either side of the casing.

et is the hook. (Shownin dotted linesin Fig. l and in side vieW'in Fig. 2.) This hook is securely attached to the inner face of the cover, and as the cover closes the barb of the hook coines into contact with the lockingarm or keeper 5, which is hinged upon the bellcrank 7 and is placed directly in the path of the hook. The keeper 5 is hinged upon the bell-crank 7 by means of a pin 6 and is turned aside by 5o means of the hook as it passes, but is immediatelyre-turned into its position, so as tolie behind the barb and prevent the openingof the cover :by means of the spring .15, which is secured gto Jthe keeper and bears upon the main =portion ,of .the .bell-crank 7. To release the cover, Ithe ventire Vbell-crank is rotated in the following manner: This bell-crankis pivotally secu-red to the side wall of the box 4by rneansfef a iv-ri'st 14, which projects through ,the case vand is provided with a slot l to receive .a Itool Yorsnitable means for rotat-in git. As seenv clearly in Figs. 2 and '6, the bellcrank is provided with a projecting arm sharpened at the extremity to the cuttingpoint 8, which is adapted to pierce a paper check or seal 9, placed where the cuttingpoint will engage it while the bell-crank is 'being rotated and before the cover can be released. The bell-crank need only be rotated yfar enough for the hinged keeper to pass the barb of the hook, when the cover can be withdrawn. As the bell-crank is turned on its pivot, the cutting-point will cut through the paper check or seal andl mark it, so as to indicate that the box hasbeen opened.

The paper check is mounted loosely in guides 10, between which it is inserted before the cover is placed on the box. check and over an opening 1l in the box is placed the glass 12, covered by the ring 13,- thus permitting the check to be seen through the casing. Y

A'spring 1S, secured at one extremity to the top wall of the box and at the other eX- ltremity to the bell-crank at a distance'from the pivotal point, instantly returns the bellcrank to its original position, (with the keeper blocking the path of the hook and cover,) where it presses against the stop 19 upon a ldisk 20, which is integral with a sleeve 21, se-

cured to the casing and through which the Wrist 14 passes. This stop also receives the pull of the cover and prevents its being opened until the bell-crank is turnedaside from the hook.

It will readilyl be seen that it is necessary to rotate the bellcrank 7 and pierce the check before the cover can be removed, and the cover must be removed before the bellcrank is released and the spring returns it to Over the p IOO its normal position, the bell-crank being held,

immovable in the meantime.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-.-

l. The combination with the box and cover thereforof a seal-holder and seal upon one of said box portions, and means for looking the box and cover together and for defaoing the seal simultaneously with the disengagement of the look, consisting of a bell-crank adapted to be rotated from the exterior of the box, mounted upon one of said box portions, and provided with a outter-arm,.and a lockingarm or keeper adapted to engage a catch upon the other portion of the box, a stop for the bell-crank and a return-spring therefor, substantially-as described.

2. The combination with the bo'x and Cover, of a seal-holder and seal, a bell-crank adapted to be rotated from the exterior of the box, and provided with a cutting-arm and a lockingarm, and mounted upon one portion of the box, and a catch upon the other portion of the box, adapted to engage said lookingarm, when the cover is closed, the catch and locking-arm being adapted to pass each other as the oover is closing,- substantially as de# scribed. i o

3. In a seal-lock the combination with a box and coveraud seal-holder and seal or cheek, of means for looking the same and for defacing the seal or check by means of the looking mechanism While disengaging the lock, before the cover can be released, oonsisting of a bell-crank operated from outside the box, and provided with defaoing and looking arms, and mounted upon one portion of the box, in combination with a catch on the other portion of the box, substantially as described.

4. In a'seal-look the combination with the box and cover therefor, of a seal-holder and seal, a looking-arm and catch, one upon the cover and the other upon the box, and an osscribed.
