many 7 Filed Oct. 8,1959, Ser. No. 845,272 Claims priority, application Germany 9st. 15, 1958 4 Claims. (Cl. 24.2-55.2)
The present invention relates to a carrier for detachably holding the ends of objects, such as a roll from which a band is unwound. More particularly, the present invention relates to a paper roll carrier for a business machine. Calculating machines, and other business machines, are generally provided with acarrier for a paper roll including two holding arms whichcan be swiveled between two positions, and can be moved in direction of the paper roll for removing the paper roll.
It is one object of the present invention to improve carrier means serving this purpose, or a related purpose, and to provide acarrier means consisting of simple and inexpensively manufactured parts which can be easily assembled without any tools.
Another object of the present invention is to provide a paper roll carrier for a business machine with holding arms resiliently urged towards each other, but held by suitable abutments in a position permitting an easy insertion of a new paper roll.
Another object of the present invention provides a roll carrier constructed in such a manner as to take up very little space and to have no projecting parts which could interfere with the operation.
With these objects in view, the present invention mainly consists in a carrier means for detachably holding the ends of an object, such as a paper roll which is to be unwound. The carrier means comprises a pair of arms between which the paper rollis turnably held, and which are mounted onan elongated support, which is preferably turnable together with the arms and the paper roll. At least one end portion of the support passes through a cutout in an arm, and is'non-circular or includes other means for connecting the arm for turning movement to the support. The support has at least one abutment against which the respective arm is urged by a resilient means preferably located in a recess or slot of the support. In the preferred embodiment of the present invention, both arms are mounted on the end portions of the support, and are urged against transverse abutments of the support by a spring located in a recess or slot of the support and held in no other way so that no tools are required for the assembly.
Preferably, transverse pins pass through the slot in the support crossing the cutouts in the arms and abutting against the arms under the action of the common spring which is connected to the two pins.
In the preferred embodiment of the present invention, the arms have arcuate holding portions in which the transverse pins rest to prevent a displacement of the pins.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its constructionaudits-method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
FIG. 1 is an elevation illustrating a preferred embodiment of the present invention, showing on the right side a first operational condition, and on the left side a second operational condition; and
FIG. 2 is a fragmentary side view illustrating a detail of the embodiment of FIG: 1 in a third operational'condition.
Referring now to the drawings, an elongated support 1 has a substantially rectangular cross section, and has two end portions 3 which terminate in journal portions 2. Journal portions 2 are turnably mounted in bearings of a pair of stationary supports 14 which are indicated in dash dot lines in FIG. 1. The journal portions 2 have part-cylindrical surfaces, and flat side faces which are a continuation of the side faces of the elongated support 1.
The end portions 3 are'narrower than the center part f support ll, so that two'transverse'shoulders or abutments 4, 5 are formed onopposite sides of each end portion 3. As best seen in FIG. 2, abutments 4 and 5 are staggered in longitudinal direction of support 1, and abutment 5 is inclined to the axis of support 1' passing through the journal portions 2, and also inclined to the respective other abutment 4.
A pair of holding arm means 6 is provided for turnably supporting a paper roll 13 between a pair of studs 12 located at the free ends of arm means 6. The other ends of arm means 6 have cutouts '7 of rectangular shape which substantially match the rectangular cross section of the end portions 3 adjacent shoulders 4 and 5. Since the end portions 3 taper outwardly, mounting of arms 6 on end portions 3 is a very easy operation.
Due to the fact that cutouts 7 and end portions 3 have non-circular loosely matching cross sections, arms 6 are connected to support 1 for turning movement. However, arms 6 can move on end portions 3 in longitudinal direction of support 1.
Support 1' has a longitudinal recess or slot 11 passing therethrough and extending into the end portions 3 slightly beyond shoulders 4 and 5. Transverse pins 8 are located in the rounded ends of slot 11, and rest on arcuate holding portions f arm means 6. Each arcuate portion 9 includes parts located on opposite sides of support 1 which passes between these parts through a cutout 7, and since portions 9 cross slot ill, a passage for pins 8 is formed when arms 6 abut on shoulders 4 or 5.
A tension spring, shown to be an elongated coil spring 10, is located in recess 11, and has hooked-shaped end portions passing through cutouts 7 and located in annular grooves in transverse pins 8.
Consequently, pins 8 are drawn toward each other, so that arms 6 are urged against abutments 4 andS, and at the same time secured against said displacement.
When no paper roll 13 is supported on arms 6, corresponding to the illustration of the left side of FIG. 1, spring ltl will pull arms 6 into a position in which arm 6 abuts on both shoulders 4 and 5. Since shoulder-s 4- and 5 on each side are slightly staggered, and preferably shoulder 5 is inclined, both arms 6 will assume the inclined position illustrated only on the left side of FIG. 1. When a paper roll is inserted between arms 6, both arms are held in the operational position illustrated only on the right side of FIG. 1. In this position, arm 6 abuts mainly on shoulder 4 and extends substantially perpendicular to the turning axis of support 1.
It will be noted that the released position of arms 6, as shown on theleft of FIG. i1, is determined by shoulders 5 in such manner that studs 12 are displaced only a small distance in axial direction as compared with the normal operative position shown on the right side of FIG. 1. This facilitates the insertion of a new paper roll.
When the new paper roll is to be inserted, as least one arm 6 is pulled into the positon shown in FIG. 2. in which the free ends of arms 6 are farther spaced from each other. In this position, a paper roll is reasily inserted, and and upon release of arm 6 it will tend to assume the position shown on the left side of FIG. 1, but will be held by 3 the paper roll in the position shown on the right side of FIG. 1.
As is clearly shown in FIG. 1, transverse pins 8 are normally in a position spaced from the rounded ends of slot 11. When a paper roll is to be inserted, and arms 6 are spread, the outward movement of arms 6 is limited since pins 3 engage the rounded ends of slot 11, as shown in FIG. 2. Consequently, arms 6 cannot be accidentally turned into an undesired position.
From the above description of a preferred embodiment it will become apparent that the roll carrier of the present invention includes no threadedly connected, riveted, or other permanently connected parts, and that all parts can be manufactured by simple and inexpensive stamping operations. Consequently, the assembly of the device is performed by unskilled workers in a very short time, while nevertheless the assembled device performs all required functions to perfection. The construction includes no elements having sharp projecting corners or edges, particularly since the spring is located in slot 11 and covered by support 1 and by the arcuate portions of arms 6.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of carriers for holding an object differing from the types described above.
While the invention has been illustrated and described as embodied in a paper roll carrier for a business machine, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
