Specification of Letters Patent. Patented Apr. 12, 1921- Application' filed February 3, 1920. Serial No. 355,915.

To all 10 ham it may concern Be it known that I, InvIN U. MINEHART, a citizen of the United States, residing at Coggon, in the county of Linn and State of Iowa, have invented a new and useful Door- Catch, of which the following. is a specification.

This invention relates to new and useful improvements in door catches or latches and the object thereof is to provide improved gravity operated latch for use on latch to be reversed for right or left hand doors, while additional means are provided folholding the door in an open position while preventing injury to one of the handles which cooperates with means carried by a wall or part against which the door moves when opened, in order to prevent injury to With the above and other objects'in view which will appear as the description proceeds, theinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown 7 can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 is a front elevation of my improved gravity door catchin applied posi. tion, the bolt being shown engaged with its keeper;

Fig. 2 is an end elevation of the device disengaged from the keeper;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 1 but showing the latch in a disengaged position;

Fig. 4: is a fragmentary perspective view showing the means of engagement with one of the handles of the catch or latch, in order to hold the door in an open position;

Fig. 5 is a detailed view of an arbor or fulcrum bar foractuating the sliding bolt; and

Fig. 6 is a perspective view of the sliding bolt.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several vlews, my improved door catch is shown as comprising a casing 10 preferably of integral rectangular outline having attaching flanges 11 at the top and bottom edges there of suitably apertured for receiving securing screws or the like 12'by which thedevice is attached to the outer face of a door or the like13 adjacent to the free edge portion thereof. The casing 10 cut or hollowed out at its inner face as shown at 14; and in rectangular outline, providing side walls 15 and 16 thelatter'of which is provided with a recess or opening '17 for the purpose of receiving the engaging end of the sliding latch bolt therethrough, as will be later debeted portions or seats 18 adapted to accommodate a rectangular cover plate 19 which 16 suitably secured as ndicated at 20 to the casing, at the inner walls of the recesses or rabbeted portions 18, as particularly shown in F igf3 of the-drawings. Alined openings 21are provided in the front wall of the casing proper and the plate 19, so as to receive an arbor or fulcrum bolt 22 having a radially projecting bit 23 preferably slightly tapered toward its free end as shown, and accommodated between the wall at the casing and the plate 19 with the arbor projecting beyond the outer faces thereof. Slidably mounted in the cut-out 14 between the top and bottom walls thereof, is a sliding bolt or catch 24 of peculiar configuration preferably having corner projections 25 at the enlarged end thereof which is provided with a series of corrugations as shown. At the tapered end of the catch plate or bolt 24, it is provided with a reduced catch portion or beveled ended bolt 26 forming end shoulders 27 at the top and bottom, designed to engage the inner face of the wall 16 through which the opening or recess 17 is provided to accommodate the portion 26. As the sliding catch or bolt 24 is mounted within the casing, it is designed to be normally engaged by the bit 23 and for this pun i the recess thereof is designated at 35.

pose the said latch plate or bolt isprovided with a cross shaped opening 28 therethrough having a series, preferably four recessed extensions 29 8XtQI1Clll1g vertically and horn, zontally in either direction for en agement" by and accommodating the bit 23. mounted on the projecting ends ofthe arbor or fulcrum bolt 22, are handles 30, each having an opening 31 therethrough and formed at one end with a reduced extension or hub 32' apertured to receive the arbor therethrongh. The arbor is shown of circular cross sec tion so as to freely rotate through the circular apertures 21 and the handles are fixed or keyed to the arbor, as by means of screws 33 engaged through the reduced portions 32' at one side and seating in the arboras shown. Obviously when these handles are raised in the manner shown in dotted lines in 2 of the drawings, they will swing the. arbor.

on its pivot to cause the bit 23 operating in the lower extension of the opening 28, to

' latter sag to prevent interference with the working of the latch. The keeper jplate is of elongated form having attaching flanges 36 at the upper and lower ends thereof suit- I ably apertured for receiving fastening screws or the like 37 in juxtapositionjto the casing 10. As the keeper plate is of right angular crosssection at the opening and cut out 35 forming the catch. escutcheon, the open side is disposed towardthe free end of the casing 10 at the wall from which thejbolt 26 projects and. the wall 38 closes the outer face of the keeper. By swinging the handles 30 to raised positions in the manner shown in Fig. 2 of the drawings, the bolt is withdrawn from the keeper and by reason of the'weight of the handles, and the beveled end of the bolt 26, the latter may be engaged with the keeper without injury to the parts, that is, automatically so as to raise the handles when the same are horizontally disposed due to the shifting of the catch plate or bolt 24 through the medium of the'arbor 22 and the bit 28,01 the catch may be engaged with the keeper by. raising'the handles manually and then releasing them when the weight of the handles acting by gravity will automatically dispose the catch In an engaged position. displacement will be positively prevented,

since the fiat face of the bolt will be presented against the innerrface of the front portion of the keeper andthedoor can manually.

In this position only be opened by raising the handles 'l'hus, the necessity of employing defective oncomplic'ated parts such as springs and other intricate constructions commonly employed in locks or the like and catches, is obviated, thereby rendering tl device especially adapted for use in connec tion with outside doors particularly barn .doors, .or in connection with refrigerators,

ice boxes and the like where rusting is apt to take place and in ure intricate parts, such as springs and the like commonly employed in this art.

. In order. to hold the door in an open position against a wall or part of'the inclosure in which the door swings, the handle at the outer face of the casing'is designed to engage a catch 39, the same being of V-shaped construction having attaching legs e0, thefeetportions 41 of which are disposedin alinement andslotted as indicated at 4:2, to receive adjusting screws 4-3 by which the catch is attached to the face of the wall a l. Thecatch 39 is providechwith a beveled'engaging portion as designed to permit the handle 30 at the outside to ride over the same, sothat said beveled portion will engage between the space'dportions of the handle produced by the opening 31 in the form of an elongated slot therein, and also forming a grip by whichthe handle maybe conveniently manipulated, so that the right angular shoulder. 46 will engage the inner wall of the one V of the spaced portions ,ofthe handle, thus closed positionuntil the handle at the .opposite side is raised. It is'understood that this engagement is automatic, especially due to the fact that the handle 30 maybe elevated by a beveled portion 45 in moving into engagement with the shoulder 46 in order to prevent injury to the handleythe catch is provided with an extension 47 at the free end thereof adapted to abut the door'or wall of the barn, asindicated vparticularly in Fig. 4i of the drawings. By

reason 'of the slots l2 and the securing means 43, the catch can be vertically .adjusted so as to accurately engage the handle.

It will thus be seen that I have provided a door catcher latch, which embodies a preventing the door fromswinging to a.

used for either right or left hand doors, the fiat extension of the fulcrum bolt or arbor 22 constituted by the bit 23 corresponding to the bit of a key, always extending downwardly for operation or" the bolt in the manner already explained. It is also to be understood that the handles are in reverse positions during this operation, simply by loosening the set screws or other fastening means employed for securing the handles to the arbon it being understood that the arbor may be squared or otherwise form d for this purpose. Since the extension or bumper a? engagesthe door, and the handle is engaged with the catch shoulder d6, the possibility of striking the handle against the wall and breaking the same, is obviated.

Having thus I claim is:

A door catch of the gravity type embodying a keeper having attaching means, a casing having attaching means, said keeper and described the invention what casing conforming in shape in end eleva tion, sald casing having a cut-out producing top and bottom walls and side Walls,

one of said side walls disposed toward the keeper being provided with a recess, said top and bottom walls being provided with rabbeted recessesya detachable cover plate secured in said rabbeted recesses, over the cut-out at the back of the casing, a latch bolt of tapered-like formation movably mounted in the cutout, the enlarged end thereof being slidably supported at the bottom of the cut-out and the reduced end thereof being formed with a beveled engaging portion with shouldered walls above and below the same, said bolt having a cross shaped opening therethrough having a series of extensions of concaved-formation extending vertically and horizontally, an arbor rotatably mounted through the casing and having a radially projecting bit designed to engage said opening and extension recesses thereof wherebv when the arbor is turned said bit engages the walls of said recesses to shift said bolt to engaging or disengaging positions with respect to the keeper, and handles mounted on the arbor. r

In testimony that I claim the foregoing as myown, I have hereto affixed my signature in the presence of two witnesses.
