CLOCK-SPRING BARREL.
LOSEJOZO.
Specification of Letters Patent.
Patented July 16, 1912.
Application filed May 31, 1911. Serial No. 630,448.
T 0 all whom it may concern:
Be it known that I, GEORGE KERN, a sub ject of the Emperor of Germany, and a resident of the city of Peru, county of Lasalle, and State of Illinois, have invented certain new and useful Improvements in Clock-Spring Barrels, of which the following is a specification.
My invention relates to improvements in clock spring barrels and has for its object the production of a clock spring barrel which is composed of thetime main wheel and a separable part attached thereto, one or both of which parts are journaled on the spring winding arbor, and its further object is to produce such a clock spring barrel by forming it up from sheet metal making it very inexpensive to construct.
In the drawings, Figure 1 is a central ver tical sectional view of one form of my clock spring barrel. Fig. 2 is an end view of Fig. 1. Fig. 8 is an enlarged partial top View of Fig. 1 showing the separable connection between the principal parts of my clock spring barrel. Fig. 4 is an enlarged partial vertical sectional view of a modification of the connection between the principal parts of my clock spring barrel.
Similar numerals represent similar parts through the drawings.
In the drawings 1 and 2 represent the plates of a clock or bridges used to support the barrel fastened to the clock plates. Journaled in these plates is a winding arbor 3, having a threaded portion 4 for the usual winding key, a squared portion 5, shouldered portions 6 and 11 and a projection portion or hook 7. Mounted on the squared portion 5 is a ratchet wheel 8 whose teeth engage a pawl 9 which is journaled to plate 1 by means of a rivet 10 and held in engagement with the ratchet teeth by means of a pawl. spring not shown. Journaled on the shouldered portion 11 of arbor 3 is a formed member 12 suitably shaped as shown, having gear teeth 13 on its outer periphery and pins 14k fastened to its smaller cylindrical projecting portion. These parts lat may be pins which are inserted as shown in Fig. 1
or may be forced or cut out of the metal forming a part of 12 by any of the known means as in the modification shown in Fig. 4. Separably attached to 12, is a cup or cup shaped member 15, which is preferably journaled on 6 of arbor 3, and which has suitably shaped. slots 16 shaped in its outer cylindrical surface which engage the pins 14 above mentioned, forming the detachable connection between the members 12 and 15. Fastened in the outer shell of cup 15 and projecting inwardly is a rivet 17 to which one end of-the clock spring 18 is attached, the other end of spring 18 being attached to the projection or hook 7 on arbor 3. The teeth 13 on member 12 engage with the second wheel of the clock train which is not shown in the drawings.
From the construction shown it is evident that should the spring 18 break, or for any other reason it is desirable to take the spring out, it is only necessary to rotate 15 on 12 until pin 14 comes against the open end of slot 16 when 15 can be pulled off. It is further evident that the construction of my clock spring barrel is very simple and eflicient and can be produced very cheaply.
It will be understood, of course that while I have here shown one form of my invention 1 do not wish to limit myself to the exact shape shown, but desire to have it taken in a sense illustrative of any or all the forms of my invention as come within the scope of my claims.
I claim 1. In a clock spring barrel, in combination, an arbor, a cup shaped member having a circular flange projecting therefrom journaled on said arbor, gear teeth formed on said flange, a similarly cup shaped member having an aperture slidably mounted on the cylindrical portion of the above mentioned cup shaped member and means for detachably connecting said members.
2. In a clock spring barrel, in combination, an arbor, two cup shaped members journaled on said arbor and slidably mounted on each other, a flange with gear teeth projecting from one of said members, and
means for detachably connecting said memmeans for detachably connecting said members. bers, szud means comprlslng a pm and a slot.
