J. SCHOR ETAL CLAMP Filed May 12, 1957 fig -l //A [Z a Z I 9 I y I INVENTOR JOSEPH 56/102 THE/1E ATTORNEY Patented Jan. 16, 1940 UNITED STATES PATENT OFFICE Skoverski, Oakland, signor to said Schor Application May 12,

3 Claims.

Our invention relates to a clamp structure for fastening the pedestal of a device, such as a butter cutter, to a table or other support. While we refer to a butter cutter in the following description, it is understood that our improved clamp structure may be used in connection with the pedestal of any device where clamping to a support is desirable for holding the device rigid.

The broad objects of our invention are to provide a clamp of the character described, which may be folded out of the way when the pedestal is moved, so that the inconvenience of a clamp dangling from the pedestal is avoided; and to provide means for holding the clamp in its folded or inoperative position.

The invention possesses other object and features of advantage, some of which, with the foregoing, will be set forth in the following description of our invention. It is to be understood that we do not limit ourselves to this disclosure of spe cies of our invention, as we may adopt variant embodiments thereof Within the scope of the claims.

Referring to the drawing:

Figure 1 is a side elevational view showing the clamp structure of our invention in operative position; and

Figure 2 is a similar view showing the clamp in inoperative position.

In devices mounted on pedestals, such as butter cutters, it is highly desirable to clamp the pedestal to a support to give stability when the device is in operation. Since such devices are made portable for convenience in moving them about, it is important that a clamp structure be mounted as a permanent part of the pedestal to prevent loss. Still another and equally important consideration is that of keeping the clamp out of the way, so that the pedestal may be moved freely about and positioned on a shelf or other place of storage, without interference by the clamp. Our improved clamp structure has all of these advantages.

In terms of broad inclusion, the clamp embodying our invention comprises an arm pivotally mounted on the base of a pedestal, for movement from an operative position depending from the base to an inoperative position lying against the column of the pedestal above the base. Means are also provided whereby the clamp arm may be shifted on its pivot to engage the arm with the base, so as to hold the clamp securely in its inoperative position.

In greater detail, our clamp structure .is mounted on a pedestal having a base 2 for rest- Calif.; said Skoverski as- 1937, Serial No: 142,152

ing on a table or other support 3, and also having a column 4 for supporting the head or body of a device, such as a butter cutter. The clamp is of substantially G-shape, having a lower arm 6 with a thumb screw 1 for clamping against the underside of the support 3. Upper arm 8 of the clamp extends upwardly at an angle, and lies along the inclined side of the pedestal base 2 when the clamp is in operative position, as shown in Figure 1.

Means are provided for mounting the clamp for combined pivotal and sliding movement on the base; whereby the clamp may be rotated upwardly out of the way, and then shifted into a position of interlocking engagement with the base. For this purpose the clamp arm 8 is provided with slot and pin connection, preferably formed by a slot 9 in the clamp arm and engaging a pin I I held by suitable ears l2 formed on the base 2. Of course this same arrangement could be obtained by stub pins on the ears engaging grooves formed in the sides of the arms; or by a pin fixed in the arm and engaging grooves or slots in elongated ears on the base; or by other equivalent means.

By this arrangement the clamp may be rotated up against the column 4, and then dropped down against the base with the arm 8 caught between the pin and base. In order to insure a snug fit between the clamp and pedestal, the adjacent edge of arm 8 is curved, complementary to the curved surface of the base; so that arm 8 is cradled in the lap of the base, with the vertical edge of the clamp lying against column 4. When it is desired to use the clamp, it is only necessary to lift it out of its locked position, and then rotate it down to the operative position.

We claim: 1

l. A clamp comprising a base, a clamp arm pivotally connected to the base for movement between retracted and clamping positions, means on said arm and operable in the clamping position thereof for clamping the base against a support, and means for mounting the clamp arm for slidable movement transversely of its pivot axis for positioning a portion of the arm against the base to lock the arm in retracted position.

2. A clamp comprising a base, a clamp arm pivotally connected to the base on a substantially horizontal axis for movement between upwardly and downwardly extending positions, means on said arm and operable in the downwardly extending position thereof for clamping the base against a support, and means for mounting the clamp arm for slidable movement transversely of its pivot axis for lowering a portion of the arm against the base to lock the arm against downpin whereby the arm may be shifted transversely ward pivotal movement. of the pin to position a portion of the arm against 3. A clamp comprising a base, a pin on the base, the base for locking the arm against pivotal a clamp arm pivotally mounted on the pin, and movement. 5 means on the arm for clamping said base against JOSEPH SCI-10R.
