PLATE-Ll FTER.

SPECIFICATION forming part Of Letters Patent No. 230,108, dated July 20, 1880.

Application filed May 27, 1880. (No model.)

To all whom it may concern Be it known that I, Moses CHURCHILL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Plate-Lifters, of which the following is a specification.

The nature of my invention consists in a device for lifting hot plates or dishes from the oven or stove, the same being made with a handle in two pieces hinged together so as to tilt from end to end, so that a pressure by the hand on one end of the handle will open the other end, and by means of connecting-rods close together toward a common center a number of arms suspended similarly to the bows of an inverted umbrella. When the arms are so drawn they will clasp under the edge of a plate by hooks on the outer end of said arms.

In the drawing, which is a perspective view, A and B are the two parts of the handle, 0 the joint which unites them. at c f are offsets radiating from the side of the end B b, (a fourth one being obscured,) from which the arms G H J K are suspended, the lower ends, G e, H 0, J c, and K e, of said arms being hooked to support the edge of the plate T T. Y

S is a piece with a hole in the middle, and slides on apost, P, projecting from the under side ofthe end B b ofthe handle A B. L, M, N, and O are rods which, by a loop at each end, connect the arms G H J K with the slide S.

r 'r is a-rod which is secured at one end into the side of the slide S, passes up loosely through a hole in the side of the end B-b, thence over the top of the upper half, at A a. of the handle A B, and thence down loosely through a hole on the other side of the end B l) and securely into the other side of the slide S.

V is a spiral spring which presses against the under side of the end B b and the upper side of the slide S, and serves to spread the two parts of the handle and the arms G H J K,

and thereby disengage and let free the plate and prepare the instrument for use.

' The device is operated by pressing together the outer end of the handle, which opens the other end, A a and B 1), moves the slide S on the post P, compresses the spring V, draws upward the connecting-rods L, M, N, and O, contracting the diametrical distances between the hooks H e and K e, and J c and G 0, thereby grasping the plate T T under the rim.

On removing the pressure on the handle the spring causes the arms to open, and the plate is freed.

The advantages of my improvement are that a single and perfectly natural grasp of the hand around the handle will close together the arms, so that the greater the weight of the plate or dish the more firmly and securely is it held, in consequence of the tendency of a heavy load on the arms to draw them toward a common center by the combined action of the arms G'H J K and the connecting-rods L M N O, and slide S on the post P.

1. The plate-lifter consisting of the arms G H J K, in combination With the ofl'sets d e f, 8tc., connecting-rods L M N O, the slide S, operating on the post P by the spring V, and the duplex rod 1" r, or its equivalent, operated by the handle A B, substantially as and for the purpose specified.

2. The device consistingof the armsG HJ K, operating in combination with the ofi'sets (1 cf, 860., connecting-rods L M N O, the slide S, and the duplex rod 1 r, by the handle A B, without the post P, substantially as and for the purpose specified.
