Claims.

Our invention relates to a new and improved combination clamp and cutter for X-ray films and for other purposes. 7

One of the objects of our invention is to provide a device having opposed jaws, for clamping the corner of an X-ray film or the like, said jaws being movable towards each other and being provided with cutting means, so that the X-ray film or other object can be released from the clamp by moving said jaws towards each other, thus cutting off the clamped portionof the X-ray film or the like.

Another object of the invention is to provide a device of simple and'eflicient construction, and which can be manufactured at low cost.

Gther objects of our invention will be stated in the annexed description and drawings which i1- lustrate preferred embodiments thereof.

Fig. 19 is a sectional view on the line ill-49 of Fig. 17.

Heretofore, in mounting X-ray films in a frame in order to hold the film flat and planar during the operations of developing, fixing, washing, drying, etc. it has been customary to provide ordinary elamps or clips, which could not be operated so as to cut the film. The conventional clamp has a punch-pin which perforates the film. After the film had been processed, it was necessary to open the clamp and to remove the film from the punch-pin, and then to cut off the corner of the film by means of a pair of scissors or by a cutter.

By using our improved device, the clamped corner or other portion of the film can be completely severed from the body of the film, so that the film can be removed from the clamps with the corners severed, causing much less delay and manipulation.

The frame I may be of any conventional or adjustable type. It is provided at its top with resilient metal members 2 and 3 which can be wires, springs, etc. Two of the combination devices C are respectively connected to said members 2 and 3, in order to exert tension on the film. The other two combination devices C are connected to the frame, adjacent the other corners thereof. The base plates of said other devices C may be connected to one or two legs of the frame, at the respective corners.

As shown in Fig. 2, each combination device comprises arms 4 and 5. These arms are provided with cooperating lugs, which are connected by a pivot pin 6. A conventional blade spring I normally and resiliently holds the arms 4 and 5 in the normal position shown in Fig. 2.

As shown in Fig. 6, one leg of the blade spring 1 is connected to the arm 5 by means of a rivet 8. The free edges of the arms 4 and 5 are provided with the cooperating side jaws 9 and I 0. The Jaw III has a sharpened shearing portion II and upstanding lugs l2 and II. The jaw 9 is provided with corresponding depending lugs l5 and I6. Between the lugs l5 and It, the jaw 9 is provided with a shearing edge. This consists of inclined or concave edge portions l1 and I8, an intermediate perforating portion i9, and edge portions 20 and 2| which are substantially parallel to the perpendicular to the axis of the pivot pin 6, when the device is in the normal position shown in Fig. 2. Said edge portions 20 and 2| can be omitted without departing from the invention, so that the concave cutting faces I! and I3 may meet in a point.

When the comer of the film is clamped between the jaws 9 and ID, the film is clamped without completely cutting it, and the perforating or punch portion l9 pierces the film. This element I9 is aligned with the cutting means, so that the hole which is formed .by member I9 is continuous with the line of cut. The elements 20 and 2| have sharp edges, but they act as stops so as to limit the closing movement of the jaws, under the force of the spring I. This position of the film F is clearly shown in Fig. 6. The corner of the film is then located, as shown in Fig. 8, between the pairs of lugs |2-|5, and |4--| B. When it is desired to cut off the corner of the film and to release the film, the jaws 9 and I are forced towards each other, until the corner of the film is completely out off by the shearing portions of the jaws 9 and I0.

Fig. 3 shows the line 22 along which the corner of the film is cut oil. This line may have any shape, instead of being a straight line, by suitably shaping the cutting elements. The portion 23 of said line shows the portion of the film which is perforated by the member l9, in order to engage the film.

When the jaws have been moved towards each other in order to cut off a part of the film, the lug I5 abuts or substantially abuts a portion'of the arm 5. Lug I5 thus acts as a stop to limit the movement of the jaws towards each other. In the cutting position of the device which is clearly shown in Fig. 11, the lug l6 laterally overlies the edge of the arm 5. For this purpose a' slot is provided in the arm 5, between the body of said arm and the upstanding jaw Ill. The jaw 9 is therefore guided relative to jaws i0, when said jaws are operated to cut the film. A supplemental blade spring 26 is connected to the arm 5 by means of a rivet 24. The free end of the lug i6 contacts with the spring 26, when the parts are in the normal position shown in Fig. 2. The force of the spring 26 is opposed to the force of the spring I, and these two springs balance each other when the device is in the normal position shown in Fig. 2. The cutting edges are then in inoperative position, because they have not cut off the corner of the film, so that the film is then held by the perforating extension.

In order to cut off the corner of the film, pressure is applied to the arms 4 and 5 adjacent the lugs I2 and IS. The spring 26 is flexed by lug it, when the jaws 9 and III are in final cutting position.

As shown in Fig. 10, an angular plate |6a is connected to the arm 5 by means of a rivet l6b. The lug I6 is guided slidably between the upstanding portion of the arm lie and the lug i4.

This embodiment is preferable to the second embodiment,'since in the first embodiment there are no punch-pins or: the like which engage the cut-off part of the film.

The second embodiment comprises arms 30 and 3|, having lugs which'are connected by a pivot pin 32b. The blade spring 33 corresponds to the blade spring I. The arm 33 is provided at its free end with a punch-pin 34a. The free end of the arm 3| has a bore in which a hollow bushing 32 is slidably located. Said hollow bushing 32 is connected to a blade spring 320 which is connected by a rivet 35a to the arm 3|. An additional reinforcing spring 35 is also connected to the arm 3| by the rivet 35a. The arm 30 is provided with a stripping spring 36 which is connected thereto by means of a rivet 31. In the normal relative positions of the punch-pin 34a and of the bushing 32, the punch-pin 34a partially enters the bore of said bushing, as shown in Fig. 17. This corresponds to Fig. 6 of the first embodiment. The arm 3| is provided with pins 33 and 39, between which the corner of the film is inserted.

In order to use the device of the second embodiment, the rear ends of the arms 30 and 3| are pressed towards each other so as to move the punch-pin 34a out of the bushing 32. The corner of the film F is then pushed between the pins 38 and 39, so that said corner overlies the bushing 32. This position is shown in Fig. 16. The arms 33 and 3| are then released. The force of the spring 33 may be suflicient or insuflicient to force the punch-pins 34 through the film F. Upon applying'slight pressure to the free or front ends of the arms 30 and 3|, the punch-pin 34a is forced through the film to enter the bore of the bushing 32. This is the position shown 'in Figs. 17 and 19. As shown in Fig. 19, the punch-pin 34 has an enlargement 34a which then abuts the top of the end of the bushing 32, so as to act as a stop.

When it is desired to remove the film, the free end of the arm 30 is pushed towards the free endof the arm 3|, so. that the bushing 32 is forced into the position shown in Fig. 18. The arm 30 is provided with a shearing jaw 4|] and the arm 3| is provided with a corresponding shearing jaw 4|.

After the corner of the film has been cut off, the jaw 40 is moved away from the jaw 4|. The stripping spring 36 has a bore through which the punch-pin 34 extends;

After the corner of the film has been cut off, the device is opened, and the stripping spring I facilitates the removal of the cut-off corner of means of which said arms 3| can be connected to the frame. As shown in Fig. 12, the combination devices can be of different shapes, but the mechanical action is the same. The frame which is shown in Fig. 12 is provided with adjusting {neans J, which may be of any conventional As shown in Fig. 8, the arm 5 of the first embodiment is fastened by means of members 5a to the resilient member 2 or 3 or to any part of the frame I.

In the broadest aspect of our invention, it covers a device having means which are adapted to grip an X-ray film or the like, without cutting off the gripped object, said means being movable relative to each other from their gripping position, either to cut offer to indent the gripped object. The invention would therefore include a device in which thefilm or the like is indented tion. Likewise the invention is not limited to a device in which the film or the like is either indented or out along the line of gripping.

, Therefore whenever we refer in the claims' to a cutter or to cutting the film or the like, we

include a device in which the film or the like is indented or scored so as to weaken the same, in addition to a device which cuts through the film or the like.

While the perforating means l9 and 34a are located on one of the jaws, in each of the embodiments described, it would not be departing from the invention if perforating means were located on each of the jaws. When the jaws are moved towards each other, the film is v first perforated and gripped. When the jaws are moved beyond said gripping position the film is cut through-and-through.

It will be noted that the'periorating position which is shown in Figs. 2 and 1'7 is in advance of the cutting position of the arms which is shown in Figs. '7 and 8. The arms are provided with spring means which maintain the same normally in perforating position.

Whenever we refer in the claims to providing one of the cutting means with a perforating extension, we include a device in which each of said cutting means has one or more perforating extensions.
