ALBERT H. MADISON, OF BRA TlFOR-D, PENNSYLVANIA.
DOQR-FASTENER FOR RETORTS. I
Specification of Letters Patent.
Patented Feb. 25, 1913.
Application filed June 18, 1912. Serial No. 704,328.
To all whom it may concern:
Be itknown that I, ALBERT 'H. MADISON, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented cer+ tain new'and useful Improvements in Door- Fasteners for Retorts, of which the follow-' ing is a specification, referencebe'ing had therein to the accompanying drawing. My invention relates to improvements .in-
' door. fasteners for retorts.
The object of my invention is to provide a door of this character in which the same is firmly held closed and inwhich said holding means braces .the door and prevents itfrom warping or otherwise beingi'njured by the intense heat, to which doors "of this character are subjected.
Another object of my invention is to provide a simple,cheap and more effective door of this character, which can be more readily locked and unlocked and having certain details of structure hereinafter more fully described.
In the accompanying drawings-Figurc l is an end view'of a retort showing the door applied thereto. Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view taken on the line 22 Fig. 1, only showing the looking bolts withdrawn from the keepers carried by the retort, and showing an asbestos packing between the door and its retort.
Retorts of the character to which my improved, door is applied are of a double wall form, having two doors and my improvement is on the inner door. is hung or hinged and fastened by an ordinary latch, but I have not shown this, as
my lmprovement is on the inner door. There is between the outer and inner door a space of about sixteen inchesforming a dead air space for the purpose, understood by those skilled in the art. Intense heat is within this space, as well as within the retort proper, and 1t is for this reason that a door has to be greatly braced in order to withstand the intense heat on each side thereof.
Referring now to the drawings, 1 represents the inner wall of the retort, which, as shown in the drawings, is provided'with a ledge 2, surrounded by the flange 3, and said ledge 2 forming the surface against which the inner face of the door is tightly clamped. The said ledge is provided with "and size to :fit
Carried by The outer door an annular groove 4 to form a tight joint with the cover, as will be later described.
The door 5 is made of metal of a character to withstand the greatest heat and of a shape within the flange 3 upon the ledge 2 and is provided with an annular flange 6, adapted to enter the groove 4. EV
"this arrangement it will be seen that atightjoint is formed between the lower face of the door and the ledge 2 of the retort, so as to'prevent the escape of any of the byproducts from the retort.
the inner face of the door 5, is an enlarged plate 7, which strengthens the door and prevents the warping thereof. The said plate at the center is provided with arecess 8, in which rotates the head 9 of the operating screw-rod 10. By this arrangement'it will-be seen that the screw-rod is free to rotate in the door. Carried by the central portion of the door is a spider 11, having its lower ends 12 bolted or otherwise secured to the door.- This spider, as shown in'Fig. 1 of the drawings, is formed of four arms and has a solid central portion 13 through which the screw-rod 1O freely passes. The upper end of the screw-rod 10 above the solid portion 13 'of the spider is provided with a large head 14, whereby the screw rod is rotated. I This head 14, as shown, allows a ratchet wrench or other .means to be applied thereto, whereby the screw-rod may be rapidly rotated, the purpose of which .will be more fully described.
Within the spider 11 is a follower 15 having screw-threaded connection with the screw bolt or rod 10. The outer edge of said follower is provided with a series of ears 16, between which the levers 17 are pivoted. The said levers 17, as shown in 95 Fig. 1 of the drawings, from the follower 15.
The upper face of the door is provided with a series of loops or guides 18 arranged extend radially in pairs in alinementwith each other, and 100 passing through each pair of loops or guides 18 is a sliding bolt 19, the inner ends of the bolts 19 being pivotally connected to the upper ends of the levers 17. The bolts 19 have enlarged outer ends 20 beyond the 105 loops 18 and the upper face of said enlarged ends have beveled surfaces 21. These enlarged ends 20 prevent or limit the inward movement of the sliding bolts 19.
The flange 3 has opposite each bolt an 110 opening 22, which has its outer face beveled to correspond with the beveled upper face of the enlarged ends of the sliding bolts, whereby when the bolts are forced upwardly the enlarged ends enter the openings 22 and firmly wedge the door down upon the ledge 2 of the retort. The door 5 is hinged to the retort by means of the hinges 23 and 24.
The turning of the screw-rod 10 causes the follower 15 to move downwardly, and through the medium of the link 17, all of the bolts 19 are simultaneously moved outwardly, securely locking the door upon the outer face of the retort. The opposite movement of the screw-rod 1O draws the follower 15 upwardly .and through the medium of the lever 17 the sliding bolts are drawn inwardly, withdrawing the ends 20 from the opening 22 of the retort so that the door may be readily swung upon the'hinges 22 and 24.
In Fig. 3 of the drawings I have shown the retort l with its outer face perfectly smooth but provided with an annular recess 27 in which an asbestos packing 28 is placed, which extends a short distance above the upper face, and upon which the cover 5 rests.
In retorts of this character the wood is loaded on cars and run into the retort and then inclosed therein by two doors heretofore mentioned.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. The combination with a retort having an opening, a ledge formed around the said opening, a flange carried by the retort on the outside of the said edge and having a horizontal opening, a door resting upon the ledge within the flange of the retort, sliding bolts carried by the door and adapted to pass into the opening carried by'the flange, a spider carried by the outer'face of the door at the center thereof, a plate carried by the inner face of the door, a screw-rod having a headed lower end between the plate and the door and free to rotate therein and passing outwardly through the spider operating means carried by the outer end of the screw-rod, a follower within the spider and having a screw-threaded connection with the screw-rod, and links pivotally connecting the follower and the sliding bolts.
2. The combination with a retort having an opening, an annular groove on the outside of said opening, a packing in said groove, 9. door resting upon the said packing carried by the upper face of the retort on the outside of the packing and having horizontal openings therein, a spider carried by the outer face of the door and having horizontally disposed guiding arm, a screw-rod having its inner end swiveled within the door and passing outwardly through the spider, a followerbetween the arms of the spider, guides for the sliding bolts carried by the door and link pivotally connecting the follower and the sliding bolts, and a hinged connection between the door and the retort.
In testimony whereof I hereunto affix my signaturein the presence of two witnesses. ALBERT H. MADISON. WVitnesses:
