NELSON TROYER AND FRANK CHESTER FOX, OF ASTORIA, OREGON, ASSIGNORS TO ASTORIA IRON WORKS, OF ASTORIA, OREGON.

HINGED RETORT-DOOR.

Application filed August 7, 1913.

To all whom it may concern:

Be it known that we, NELSON TROYER and FRANK Fox, citizens of the United States. and residents of Astoria, in the county of (latsop and State of Oregon. have invented a new and Improved Hinged Retort-Door, of which the following is a full. clear. and exact description.

()ur invention' has reference more particularly to a hinged door for use on a retort or receptacle used for cooking fish, fruits. vegetables and other food materials by steam. hot water or other artificial means, after the material has been placed in cans, glass jars, or other receptacles.

The general object of-our invention is to provide a retort door capable of being operated "ery quickly and with facility. and

which will effect a steam tight closure of the retort.

It is a design of our invention also to provide a door. the body of which will have a degree of flexibility on its hinged supporting members, whereby the door will be properly seated when closed.

The distinguishing features of the invention and the important structural, elements characterizing the practical embodiment which is illustrated as an example. will be more particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification, in which si'milar characters of ref erence indicate corresponding parts in all the views. j

Figure 1 is a front elevation of one example of our invention embodied in a retort door, showing the same applied: Fig. 2 is a horizontal section: Fig. 3is a side elevation; Fig. 4 is a vertical section: Fig. 5 1s a detail vertical section showing the manner of effecting an engagement between the door body and a hinged member forming part of the door; and Fig. (3 is a diagrammatic view showing in side elevation certain elements forforcing the door to a tightly closed position.

It is to be understood that our invention is applicable to retorts, round, square, or of other form in cross section, and is applicable to retorts disposed vertically or horizontally. In the illustration the retort is presumed to be horizontal.

In the drawings a portion of a retort is Specification of Letters Patent.

ets' 16 or their equivalent, the separate forming of the frame and covering of the door body being preferred in practice in the case of large doors for which it is not so practical to make the door body all integral.

The door body is secured to a transverse bar or bars 18, as by rivets 19, the bars be mg preferably T-shaped in cross section,

and said bars are hinged to the head 11 by a hinge pin 20, which passes through eyes 18 on the bars 18, and through lugs 21 on said head. In addition to the hinged bars 18, transverse bars 22 are comprised in our improved door, at the top and bottom respectively of the door, and are hinged to the retort head by thehinge pin 20 which passes through eyes 22 on the said bars It is to be noted that the hinged bars 22 are not fastened to the door body, but have the character of floating bar's. There is a guided engagement only between the body and the floating hinge bars, so that there can be a bodily relative adjustment thereof. Asone expedient for effecting the guided engagement between the floating hinged bars and body we have shown straps 23 secured by bolts 23 or their equivalent to the door body. and each formed at the free end thereof with a U-bend 23 presenting an open side so that the bent ends of the straps fit loosely over the shanks 22 of the floating bars which are T-shaped in cross section.

To provide for a bodily transverse adjustment between the door body and the floating hinged bars, we may employ adjusting screws 21 which take into bosses 22 on said bars, the forward ends of the screws bear ing against the outer faces of the door and preferably against the frame 16 thereof. In the adjustment of the screws 24 the engaged portion of the float bars has sliding movement in the bent ends 23 of the straps 23. Lock nuts 21 are employed on the screws if desired.

-In addition to the bodily relative adjustment between the floating hinged bars and the door body, we provide for a degree of adjustment and relative flexibility between the door body and the hinged bars 18 which are fastened to said body; thus it will be observed in Figs. 1 and 2, that the fastening elements 19 that secure the door body to the hinged bars 18 are inward from the ends of said bars, thereby leaving the door body free from the bars 18 along the hinge edge, and the free edge of the door, and to spring the free portions of the door body relatively to the hinged bars 18,. adjusting means 1s provided, preferably in the form of adjusting screws 25, which take into bosses 18 on said bars, the forward ends of the screws bearing against the outer face of the door frame 16 directly over the head 15 and packing 11.

As will be clear from the foregoing, the door will have a high degree of flexibility in that it has no rigid relation to the tloating hinged bars 22, and that the vertical edge portions of the door are tlexible with respect to the supporting hinged bars 18, the

result being that the door body will have freedom to accommodate itself to the seat provided on the door head, thereby making it feasible to efi'ect a close bearing of the door when closed against the retort head. Moreover, the adjusting screws serve to correct any inaccuracies in the assembling of the diii'erent parts and provide also for taking up wear.

In order to center the door to the retort opening and alme the packing strip 13 and bead 15, a roller 26 is mounted in the lower end of the door between dependent lugs 27 on the door frame 16, which form bearings for the pin :28 constituting the axle of the roller. The said roller contacts with a fixed incline 29 on the head 11. Thus, should the door sag-by reason of wear on the hinges, or otherwise, it will nevertheless be prpperly centered.

A latch 30 is pivoted at one end, as at 31, to the door body, to swing in a keeper 32 and is adapted to engage over a catch 33 on the head 11, being provided with a loop 34 to constitute a handle. \Vhen the door is SWI Ag toward the retort, the latch will be engaged with the catch 33 so as to hold the door partially closed, the door still inclining slightly to the face of the head 11. In this position the hinged end of the door will, however be sutliciently close to the head 11 for the bead 15 to lie close against the adjacent portion of the packing strip 13.

We provide a novel means for forcing the door tightly to a bearing against the head '11, with the head 15 pressing on the packing strip 14 throughout the whole length of the latter to effect a steam-tight closure of the retort. To effect the desired tight closure of the door we provide a series of cams to engage the several hinged bars and actuating means therefor. Thus on each bar 18 and :22 at the end opposite the hinge, a friction roller 35 is secured, and on the head 11 a corresponding series of cams (designated generally by the numeral 36,) is mounted, ach cam having a pivot pin 37 journaled in a bearing lug 3; on the head 11, so that the cam may rock in a vertical plane. 011 the outer end of each element 36 an arm 38 is formed, which is adapted for hooked engagement with the adjacent roller when the door is held in the partially closed position by the latch 30. At the inner side of the arm 36 and continuing across a line intersecting the pivot 37 is an internal cam surface 35), which contacts with the roller 35 when the cam is rocked in an upward direction, and the cam surface is such that the distance between said surface and the center of the pivot 37 is graduallyless from the outer endof the arm 3b, the result being that a forced contact of the cams against the rollers will carry the rollers and the hinged bars in the direction of the face of the retort, thus forcing the door body to a firm bearing against the head of the retort, and effecting a steam tight contact between the rib l5 and the packing 11.

In order to operate the cams simultane ously, each is pivotally connected as at 10, by bolts rl-l or the like to a connecting rod 42, and the latter in turn is connected by a link 43 to a lever 11, which is fulcrumed as at 14 on the head 11, the arrangement being such that the rocking of the lever 41 in an upwa'rd direction will cause the arm 38 of each cam to have hooked engagement with the adjacent roller 35, and tightly close the door as described. The lever it may have its handle or outer portion 45 formed with a socket to be readily detachable where space is not available to leave it projecting. Also to hold the lever in the raised position to prevent its being accidentally thrown downward, a hook 16 may be pivoted, as at =17, to

the head 11, in a position for its hooked end to engage in a hole 18 in the lever.

Since the action of the cams on the rollers 35 may tend to exert an upward thrust on the bars 22, we provide means to resist such thrust, the means consisting of fixed lugs or equivalent elements to be engaged by the bars or parts appurtenant thereto. As an example of means for the purpose we have shown lugs 49, 50, on the door, projecting forwardly therefrom sufficiently to overlie the floating hinged bars 22, and thereby receive and resist the upward thrust of the cams.

The floating bars, it will be seen, constitute hinged clamping bars independent of the door-supporting means to press the door to a tightly closed position under the influ- Having thus described our invention, we-
