HAM BOILER.

Application led. May 5, 1924.

This invention relates to appliances for the cooking of hams or other meats in the piece or other food products in any bulk form, with provision for molding or compressing' the same during the cooking action.

Among the objects of the invention is to provide a cooking' receptacle, referred to hereinafter for convenience as a ham boiler, having a receptacle or body portion, a cover or closure for the receptacle, improved hand power fastening means between the closure and the receptacle, and with a resilient cushion means associated preferably with the cover to compensate for variations in bulk during the cooking action, such as would result from either swelling or contraction of the commodity or the like, and to provide peculiar and novel means for attaching the fastening and handle means to the cover and provide improved seats for the cushion devices.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying` drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical sectional View approximately along the vertical central plane of the device.

Fig. 2 is a plan view.

Fig. 3 is an end elevation.

Fig. 4E is a detail of a modification.

Fig. 5 is a plan view of the same.

Referring now more specifically to the drawings I show a receptacle formed as by stamping or the equivalent from sheet metal of any suitable strong, rigid, non-con rodible material. This receptacle is shown, especially in Fig. 2, as of oval form but with substantially vertical walls and is provided around its upper open top with an outwar ly projecting flange 11, said flange lying substantially in a horizontal plane except at the ends where downwardly deflected lips 12 are provided. f

The cover or closure 13 is substantially a flat member but having a downwardly turned marginal flange 111 which is adapted to move downward fairly close to the in- Serial No. 711,1e6. p

ner surfaces of the receptacle walls. The main portion of the cover is `substantially flat and imperforate, a form best calculated for ready, easy, and relatively cheap construction from sheet metal as by stamping.

15 indicates a handle or bar of any suitable material or construction as, for instance, a casting having forks 16 at its ends and having formed along the lower surface not far from the respective ends a pair of bosses 17 forming seats, and these bosses are pr0- vided with central vertical holes 18 which merge into counter bores 19 at the top of the bar. 20 indicates a pair of catch members in the nature of racks which may be formed in any convenient manner and each havingat its upper end a knuckle portion 21. Each catch 20 is suspended by a pivot pin 22 passed through the spaced lugs of a yoke shaped hand power lever 31, said lugs 30 in turn being pivoted on pins 32, eccentric to the pin 22 and attached to the ends of the fork 16. In the open position of the parts the levers 31 are directed upward as in dotted lines of Fig'. 1 and with the rack pivots 22 below the pivots 32. W'hen the levers 31 are then swung outward from each other and downward the pivots 22 are swung around or past the vertical plane of the pivots 32, relatively, insuring that the levers 31 will be self retained against the racks and with the springs under suiiicient compression for the purpose of the device. The racks are afforded a sufficient degree of tilting around the respective lips 12 to enable the aforesaid relative movement or interchange of position of the two sets of pivot pins.

In the modified form of Figs. 4 and 45 the levers 31a swing upward'and toward each other into locking and holding position. Otherwise the action is substantially` the same in both arms. The ends of the bar, however, are in the form of simple knuckles 16a instead of forks as above described, and the upper end portion of each rack 2O consists of a pair of spaced lugs 21a instead of a simple knuckle 21.

A pair of springs 24 are shown interposed between the bar 15 and the cover 13 to afford the desired resiliency or cushioning eect above referred to. The upper ends of the springs are seated upon or around the bosses 17 while the lower ends of the sprinefs are seated upon or around a pair of housings 25.

Each housing 25 consists of a hollow boss 25a for the reception and accommodation of a nut 26 within it, and integral with the boss 25EL is a horizontal flange 25h. rIhese hous ings are readily formed from sheet met-al by stamping or the like and the material there` of is of such a nature as to be readily and directly connectible to the upper surface of the cover 13. As shown at 27 the preferred manner of securing the housings 25 to the cover is by direct welding et the flanges to the cover. This may be by any suitable process such as spot welding, acetylene welding or its equivalent, but in any event the connection is strong, rigid, and permanent, and the nut 26 is then retained within each dome or boss 25a. rEhe boss 25 is preferably formed as a counter partot the form in plan oi'f the nut, shown as hexagonal, so as to hold the nut from rotation. Within the center oi the top of the boss formed a smooth hole 25. The attachment means between the bar 15 and the cover connections are shown as consisting ot a pair ot bolts 28 whose lower threaded ends project freely through the holes 25c and have threaded engagement within the nuts 26 while the extreme ends thereo't bite snugly against the original surface ot the cover below the nuts, thereby locking the bolts rigidly in place as anchored by the bolt nuts. The upper shoulder portions ot the bolts have slidable movement in the holes 18 ot the bosses 17 while the heads normally are depressed within the counter sinks 19u When,y however, the bar is depressed 'torceably with relation to the cover, compressing the springs 24, the head ends ot the bolts may project upward somewhat above the normal position. Thus I provide by means et the housings 25 and the parts co-operating therewith a substantially permanent connection between the bar and the cover and with interposed cushions, such connections, how-- ever, being removable or interchangeable in the event ot necessity at any time by the use of tools, although the housings are retained as rigid fixed parts of the cover.

In operation a ham or its equivalent after being made or prepared is put directly into the receptacle, and the cover being manipulated by the handle, or bar 15, is put directly upon the ham, the operator bringing downward upon the ends of the bar only about enough :torce to insure temporary holding ot the catch members upon the lips l2. ylhen the levers 31 are swung around their pivots 22 and 32, according to the construction or manner of hanging the racks above described, bringing the pivots 22 past the dead centers ot the pivots 32 and insuring the proper degree of compression of the ham within the receptacle. It will thus be seen that a very moderate amount ot torce applied to the levers 31 will insure ample compression of the springs and ham and such compression will react in such a manner with respect to the two sets ot pivotpins as to insure selt locking of the parts. The levers, however, are easily swung to unlocking position when thc cover is to be removed.

I claim:

1. In a ham boiler, the combination 'of a metal cover, a handle spaced above the cover, and connections between the cover and the handle comprising a bolt extending Jfrom the handle to the cover and having its cover end threaded` a metal housing welded to the cover and having a hollow boss with a hole therethrough through which the threaded end ot the bolt projects, and a nut housed within the boss and having threaded interlocking engagement with the end of the bolt, the threaded end ot the bolt having biting engagement directly with the surface ci the cover within the housing.

2. In a ham boiler, the combination with a receptacle and a cover movable within said receptacle to compress the contents thereof, ot combined power application and locking means for said cover comprising a handle and a lever having pivotal engagement with the handle, and a hook having` direct eccentric pivotal engagement with said lever and extending' downwardly into engagement with the receptacle, whereby when said lever is swung about its pivot to lie alongl the top ot the handle and in locking position, a downward torce is exerted upon said cover to depress the same into the receptacle and to lock it in position.

In testimony whereof I affix my signature.

HANS ADELMANN.
