FLASK SLIDE FITTING Filed llay 3, 1928 IN VEN TOR. d e/60a 5012a ILE-4 AM A TTORNEY Patented Feb. 11, 1930 PATENT OFFICE STEPHEN BONA, F BRIDGEPORT, CONNECTICUT FLASK SLIDE FITTING Application filed May 3,

The main object of the invention is to provide a flask slide fitting consisting of a guide pin, and a follower of novel and improved construction adapted to be associated with .5 said guide pin in such manner as to insure that there will be no tilting, shifting, or rocking of a member or section of a flask while being associated with or removed from a different section or member of the flask.

With the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as 15 hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being permissible so long as within the spirit of the invention and the scope of the appended claims. v

In the accompanying drawing forming a part of this specification,

Fig. 1 is a front elevational view of a flask slide fitting in which the features of the invention are incorporated, disclosing parts of the drag and cope sections and the pattern or match plate of the flask in elevation;

Fig. 2 is a side elevational view of the fitting, disclosing the drag and cope sections and the pattern or match plate of the flask in section;

Fig. 3 is a central vertical sectional view of the fitting, disclosing the drag and cope sections and the pattern or match plate of the flask in section;

Fig. 4: is a top plan view of the fitting; and

Fig. 5 is a top plan view of a flask having two fittings made in accordance with the in vention.

The flask illustrated consists of a drag section 10, a cope section 11, a pattern or match plate 12, and a plurality of flask slide fittings (usually two), represented generally at 13, designed with the purpose in view of insuring that a part of a flask while being placed upon or removed from a stationary part of the flask, will be caused to travel in a vertical plane, directly toward or away from said 1928. Serial No. 274,911.

stationary part, without tilting, shifting, or rocking relatively thereto.

In Fig. 5 I have disclosed two flask slide fittings 13, at opposite sides or ends of the flask. These may be duplicates, and but one need be described.

A bracket ll removably attached to a face of the dra section, as by screws 15, includes. spaced apart bosses 16 cut away to provide vertically aligned depressions 17. A vertical guide pin 18, situated in the depression 17, is removably secured to the bosses 16 in any convenient manner, as by screws 19. The guide pin is desirably cylindrical, but could be some other suitable shape.

A bracket 20 has slots 21 in its inner edge adapted to receive small bolts 22 passing through tl e pattern or match plate 12. Nuts 23 upon threads of the bolts 22 and adapted to engage the lower face of said bracket 20, complete a construction making provision for removably attaching the bracket 20 to the pattern or match plate in such manner that said bracket can be adjusted inwardly and outwardly of the pattern or match plate and securely fastened down at any desired position, as will be obvious. A vertical part 24: of the bracket- 20, extending through an opening 12 in plate 12, has inwardly extending, spaced apart ears 25 between which a web 26 of a follower 27 is pivoted as indicated at 28. The face of the follower is shaped to preferably embrace the guide pin 18 throughout approximately one-half of the circumference of said pin, and the axis of the follower is desirably situated at about its midlength. (See Fig. Small coil springs 29 having their opposite ends fitted. upon

protuberances

30 and 31 of the vertical part and follower, respectively, at the upper and lower extremities of said vertical part and follower, serve to cause the follower to normally assume vertical position to more easily find the guide pm.

A bracket 32 removably attached to the cope section, as by screws 33, has a horizontal part 34 extending outwardly from the cope section and provided with an opening 35. A bracket 36 has slots 37 in its inner edge adapted to receive small screws 39 entering the horizontal part .34 and adapted to function in about the same manner as the nuts 23 to removabl and securely attach the bracket 36 to the horizontal part 34 and allow inward and outward adjustment of the bracket 36. A vertical part 41 of the bracket 36 has inwardly extending, spaced apart ears 42, similar to the ears 25, between which a web 43 of a follower 44 is pivoted as indicated at 45. The face of the follower 44 is shaped to preferably embrace the guide pin 18 in about the same manner as the follower 27, and the axis of said follower 44 is also at its midlength. (See Fig. 3.) Small coil springs 46 and protuberances 47 and 48 on the vertical part 41 and the follower 44, respectively, at the upper and lower extremities of said vertical part and follower, function to cause the follower 44 to normally assume vertical position to more easily find the guide pin, in precisely the way as already described in connection with follower 27.

The manner in which the flask slide fitting operates will be apparent. In Fig. 5 a set of fittings are arranged opposite each other upon the sides or ends of a flask. In practice, when associating the pattern or match plate with or removing said plate from a flask section, or when associating a flask section with a different flask section or with the pattern or match plate or removing said flask from said different flask or plate, the part of the fitting being moved should be positively guided by the part of the fitting remaining stationary, in order that there can be no tilting, shifting, or rocking of the member being moved relatively to the stationary mem- It will be obvious that either of the

followers

27 or 44 will of necessity embrace the guide in 18, no matter whether said guide pin is s anting toward or away from the flask, during the entire passage of the follower along the guide pin, for the reason that the upper and ower portions of the follower can swing about the follower axis, toward and from the guide pin, and the arrangement will be particularly effective to prevent sidewise tilting of the part of the flask being put in motion during association or disassociation of flask parts.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

l. A flask slide fitting comprising a guide pin secured to a flask member, a follower for said pin, a bracket upon a different flask member pivotally supporting an intermediate portion of said follower, and coil springs between said bracket and end portions of said follower. i

2. A flask slide fitting comprising a guide pin secured to a flask member, a follower for said pin and adapted to embrace a portion only of the perimeter thereof, a bracket upon a different flask member pivotally supporting an intermediate part of said follower, and coil springs between said bracket and end portions of said follower.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 7th day of March, A. D. 1928.
