SPECIFICATION forming part of Letters Patent No. 5 29,856,'dated November 27, 1894. Application filed April 13, 1894. Serial No. 507,346. (No model.)

To all whom it mayconcern:

Be it known that I, HARVEY FELDMEIER, a citizen of the United States, residing at Little Falls, in the county of Herkimer, in the State of New York, have invented a new and useful Improvement in Cheese-Presses, of which the following is a specification.

This invention relates to that class of cheese presses in which the press frame, in which the cheeses are pressed, ismovable up and down and so connected with apressure block that pressure is applied thereto automatically by the weight of the descending press frame and its load. x

The object of this invention is to produce an automatic cheese press of this character which is simple in construction, easily operated and which is efficient in use.

In the accompanying drawings consisting of four sheets: Figure 1 is a side elevation of my improved automatic cheese press, showing the press frame in its lowest position; Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal sectional elevation of the press, in line 3-3, Fig. 2, but showing the press frame elevated. Fig. dis a vertical cross section in line 4.4., Fig. 1. Fig. 5 isa fragmentary vertical cross section, in line 5-5, Fig. 1. Fig. 6 is a vertical section through 'one of the journals of the movable press frame, in line 6-6, Fig. 4, on an enlarged scale. Fig. 7 is a perspective View of one of the journal sockets. Fig. 8 is a side elevation of my improved press, showing a difierent construction of the stationary frame and ofthe connection of the automatic block therewith. Fig. 9 is a longitudinal sectional elevation of the head end of the press. Fig. 10 is an elevation of the head end of the press. Fig. 11 is a top plan view, partly in section, of the foot end of the press. Fig. 12 is a side elevation of a modified construction of my improved press. Fig.1?) is a top plan view thereof. Fig. 14 is a diagram illustrating the operation of my improved press. I

Like letters of reference refer to like parts in the several figures.

In Figs. 1 to 7, A represents the movable press frame which may be of any suitable construction and which is preferably composed of longitudinal side pieces a, longitudinal bottom pieces a, a head cross piece a and a foot cross piece a l 1 B represents the stationary supporting frame which may be of any suitable construction and which is preferably composed of longitudinal base sills b, uprights or posts b, diagonal braces b and suitable cross pieces.

' The'movable press frame A is mounted on the stationary supporting frame by a transverse pivotal connection which is located near the head of the movable press frame; so that the latter can swing with its free or foot end in a vertical plane about this pivoted connection as a fulcrum. This pivotal connection is preferably formed by two transverse journals-C, which are secured in line with each other to the under-side of the bottom pieces of the movable press frame, and socket pieces 0' which are secured to the lower portion of the stationary frame and. in which these journals are seated.

' D represents the movable head block of the press which is arranged in the movable press frame A in any suitable manner, and which is preferably provided with a device by whichthis block can be actuated by hand, as for instance a screw d which works in a screw nut d in the head cross piece a a ratchet wheel d secured to the screw, and a pawl lever (i E represents the automatic pressure block which is arranged in the movable press frame near the foot or'free end thereof.

F represents a gang of cheese hoops arranged between thehead block and the automatic pressure block. The latter is provided with arms 9 which project laterally beyond the side pieces of the movable press frame on the upper andolower sides thereof and which guide the block on the press frame.

H represents chains which are attached with their rear ends to the arms of the automatic pressure block and which connect the latter with the stationary supporting-frame at points which are located at a suitable distance from the pivotal support of the movable press frame. As shown in Figs. 1 and 2, these points are located on both sides of the uprights b, which latter are provided for the purpose with hook it with which the chains are engaged. Each uprightis preferably provided with an upright series of such hooks so that the chains can be attached higher or lower, as may be most desirable. By raising the points of attachment the pressure exerted upon the automatic block is reduced,and by lowering the same the pressure is increased.

The chains form a pivotal connection between the automatic pressure block and the stationary frame. The fulcrum of this pivotal connection is located at the points at which the chainsare attached to the stationary frame and this fulcrum is arranged eccentrically with reference to the fulcrum on which the movable press frame swings. The position of the automatic pressure block in the movable frame is controlled by its connection with the stationary frame, and the position of the head blockis controlled byits connection with the movable frame, which two movements take place in arcs struck from these centers, as indicated in the diagram, Fig. 14, in whichz' 2' represent the arc in which the automatic pressure block tends to move by reason of its connection with the stationary frame and j j the arc in which the head block tends to move by reason of its connection with the movable frame. The two arcs approach each other in a downward direction, and itfollows from this that the descent of the movable press frame from its elevated position causes the automatic pressurev block and the head block to approach each other and exert pressure upon the cheese. It also follows from this that by forcing the head block toward the automatic block, by operating the screw of the head block, the press frame is swung so as to be elevated.

In the use of this press the automatic block is attached to the stationary frame at the proper point and the cheeses are placed between the head block and the automatic block. The head block is then forced toward the automatic block by the screw mechanism, whereby the preliminary pressure is applied and the movable frame is elevated. The weight of the elevated movable frame and its load then causes a constant automatic pressure to be applied to the automatic block, which pressure is exerted until the frame has descended to its lowest position. If the cheeses are not sufficiently pressed when this position has been reached the press frame can be again elevated by further moving the head block toward the automatic block. The movable frame is preferably supported in its lowest or horizontal position by legs K, and is preferably held against lateral vibration by upright guides secured to the stationary frame and bearing against the sides of the movable frame.

The construction of the press represented in Figs. 1 to 7 is very simple and is particularly suitable for the purpose of changing existing, non-automatic cheese presses into automatic presses.

In the construction of the press represented in Figs. 8 to 11 the connection of the automatic block with the stationary frame is effected by somewhat difierent mechanical appliances, but without changing the principle of the press. In this construction the stationary frame is provided at the head end of the press with a transverse bar or shaft Z which is supported ata suitable height above the base timbers by an inclined arm L and a tie rod Z. The arm L is supported at its lower end in the line of the pivot on which the movable press frame swings and has its bifurcated upper end provided with bearings Z in which the bar Z is supported. The tie rod Z is connected at its lower end with the stationary frame outside of the pivot line of the movable frame and connects at its upper end with the bar Z between the bearings of the inclined arm L. The tie rod Z is composed of two parts, adjustably secured together by a turn buckle or other suitable means, so that the rod can be lengthened or shortened, whereby the bar Z is raised or lowered to change the leverage with which the automatic pressure is exerted. The bar Z is connected with the automatic pressure block by longitudinal rods m and the arms m of the automatic block to which these rods are connected project through longitudinal slots m formed in the side timbers of the movable frame.

In the construction represented in Figs. 12 and 13 the head block is not provided with a hand actuating device, so that the press operates entirely by automatic pressure. The head block is supported by pins 'n which are inserted in a pair of openings 72', of which there are two longitudinal rows in the movable frame, so that the position of the head block can be adjusted to the number and position of the cheese hoops in the press. The press frame is elevated by a tackle O, or other suitable means, the cheeses are then interposed between the two blocks, and the press frame is then released, whereupon the auto matic pressure is applied during the descent of the press frame. As shown in these figures, the automatic pressure block is connected with the uprights of the stationary frame by rods 19 which are secured to the uprights by pins or bolts q inserted in openings in the uprights. A vertical row of such openings is preferably formed in each upright so that the point of attachment can be raised or lowered.

It is obvious from the foregoing that the mechanical features of my improved press can be varied in many ways without departing from the spirit of my invention.

I claim as my invention 1. The combination with a press frame pivoted near its head end to be capable at its foot end of vertical movement and provided with a head block, of an automatic pressure block arranged in the press frame, and a connection extending from said automatic block to a stationary support which is arranged near the head end eccentrically with reference to the pivot of the press frame, substantially as set forth.

2. The combination with a stationary supporting frame, of a movable press frame supported near its headon the stationary frame by a horizontal pivot, a head block and an automatic pressure block arranged in the movable frame, and a connection extending from the automatic block to the stationary frame and attached thereto outside of the pivot line on which the movable frame swings, substantially as set forth.

3. The combination with a stationary supporting frame, of a movable press frame supported near its head on the stationary frame by a horizontal pivot, a head block and an automatic pressure blockarranged in the movable frame, a connection extending from the automatic block to the stationary frame, and means-whereby the points of attachment of said connection to the stationary frame can be raised or lowered, substantially asset forth.

4. The combination with a stationary supporting frame, of a movable press frame supa head block and an automatic pressure block arranged in the movable frame, and a connection extending from the automatic block to the stationary frame and attached thereto outside of the pivotline of the movable frame, substantially as set forth.

Witness my hand this 6th day of April, 1894.
