JOHN n. BALDWIN, OE NAsHUm NEw HAMPSHIRE, AssIeNOE To HIMsELE AND THE MILES. ALARM-TILL.MANUFACTURING COMPANY, OE PROVIDENCE, RHODE Letters Patent No. 103,124, dated May 17, 1870.

IMPROVEMEN T IN ALARM-TILLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom/it mag/ concern: Beit known that I, JOHN F. BALDWIN, of Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Improvement in Alarm-Tills; and I do hereby declare that the following is a full, clean-and' exact description thereof, which will enable others' skilled .in the `art 4to make and use the same, reference being had to the accompanying drawings forming part of this specitication.

This invention relates'A to improvements inf alarmtills, and consists in mounting the boltslin' av tilting case, withwhichthe bell-hammer catch is combined fin such away that an effort to withdraw the till `without retracting the bolts will cause 'the case to: l

swing back against the bell-l|ammer catch and trip the hammer, to allow it to sound the alarm.

The invention also comprises a novel construction and arrangement of' parts, so as to be cheaply constructed. l

Figure 1 is a scc-tional elevation of my improved till, taken ony the linea a: of fig. 2.

\ Figure 2 is a section on theline y 'y of `iig. 1.

Figure 3 is atop viewof'a part of th'e till.

' Similar letters, of reference indicate corresponding parts.

` A is 'the drawer Or till.

B, the top, or a section of the table or 4desk into which thetill slides.

C is the hell,

l D, thehammer, and

E, the short arln thereof, which is held by the retaining-catch against the action of the springF, which forces` the hammer against the-bell.

When thecatch isdisengaged this spring is conl .nected'to the lng G, attached tothe short arm E, and arranged to strike'against the plate H, when the arm E is let go, to produce th'e necessary springing action `of' the bell-hammer stem` for striking the bell.

The bell-hammer is `p ivoted at I, in ears projecting from the sidefof the plate H.

'The arrangeme-ntth`us far described does not diier materially `from the commoiarrangements. l

I proposeto employ 'a spring catching and tripping lever, I, for holdingand tripping the' short arm E of the bell-hammer stem, the same beingv suitably pivoted at K, or'thereabouts, and provided with anotch, L, and in connection with it I employ a tilting bolt- Vc ase,`M, carrying vertically-moving bolts N, and vso arranged that when 'the till is pulled forward without l irst causing the bolts to drop, the contact of the latter against the Acatch-plate O will tilt the case back, and cause a projection, P, at one side of the case M, and above the descendingly-inclined arm of the catolilever L, to bearuponzthe latter,force it down, and

disconnect the bell-hammer.

-The catch I is thrownlup again to catch the arm EV by the spring Q, when pushed back by striking the `stud R, projecting from the top B, at the time the till is shoved home, and the case is restored by the spring R.

shiftingl the curvedv partsN' of the yboltfsfront or rear, they maybe so placed as to stand in the elevated "position with the upper ends behind the catch-plate 0,',or be dropped below and pass under it. The combinations are `changed by shifting the bolts in this way.

The pivot-bolt T vof the dogs S is also the pivotof the case M, and the dividing-plates V are supported on it. -It is supported at the ends in the plates H of the outer case.

To facilitate'the removal of the boltsfor changing'v the combinations,l the side plate-'W is applied in grooves in the end plate X, so as to be dropped in and taken out readily, and this plate Wand the frontside plate have V-grooves for confining the dividing-v plates V.

Y represents stop projections, toprevent the'case M and the bolts from being tilted toO far back.

It will be seen that, by tilting the dogs S backward by the pull-slides Z and the rods Z', some of the bolts will be thrown up and others down, and by rpulling only those which let the bolts fall, the'till will be unlocked, and these being known to the: authorized person, enables him to openI the drawer readily without striking the bell.

It will also be seen that the case is made wholly, or

nearly so, by casting, and that the dividing-plates and the side plate Ware held together 'without the aid offastenings,-other than the grooves which are formed in the plates when cast, and which receive the edges of' the dividing-plates and of the side plate W.

I do'not claim the locking-bolt and three-armed lever as new, but freely concede them to `be old and well known to the public.

Having thus described the invention,

I claimias new and desire to secure by Letters Patent- 'l l. The combination of the tiltingcase, the-lock ing-bolts, and the bell-catch lever, substantially4 as specified. l

2. lThe locking-bolts N, provided with the curved ends N', and combined with the tilting dogs S and a tilting case, M, substantially as specified.

.3. The case M, provided with the detachable slide W, the Idividing-plates V, and pivoted ou the-rod T,

substantially as specified.
