HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 491,524., dated February 14, 1893.

Application filed September 10, 1892. Serial No. 445,571. (No model.)

To all whom it may concern:

Be it known that 1, FREDERICK BURMEIS- TER, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and Improved Hot-Air Register, of which the following is a full, clear,and complete description.

The nature of my invention relates to a register in which the different parts are cast in such a manner that they are all ready for use when they leave the foundry, with the exception of two threaded openings, and one screw which holds all of the parts together.

The object of myimprovement is to provide a practical register which is simple and inexpensive in construction and can be quickly and easily put together.

That my invention may be seen and fully understood by others reference will be had to the following specification and annexed drawings forming a part thereof, in which- Figure 1 is an enlarged top view of the register; Figs. 2 and 3 are opposite end views; Figs. etand 5 are opposite sectional end views; Fig. 6 is a view of the bar by means of which the leaves are opened and closed; Fig. 7 is a View of the locking-bar and the segment which reciprocates the bar shown in Fig. 6 and Fig. 8 is an end view of one of the leaves.

Similar letters of reference designate like parts in the drawings and specification.

The frame A, Figs. 1, 2, 3, 4 and 5, hasaboss B in each of the four corners. An opening B is cored out of the upper part of the boss B and through the four openings thus formed are passed the screws which secure the perforated top or cover to the register. The perforated top is common to all hot air registers and it has not been deemed necessary to illustrate or describe the same in connection with this case. The notches A, in the top of the frame A, are to receive corresponding projections on the under side of the perforated cover for the purpose of holding said cover more firmly in place.

Surrounding the interior of the frameA at the base are the flanges a and a, Figs. 1, 4 and 5. The flange a,on one side of the frameA,is elevated above the flange a on the remaining three sides, as shown in Figs. 4 and 5, forthe purpose hereinafter described. Cast on the end sections of the flange a are the bearings 19 and b and communicating with the interior of the bearings 11 are the openings 0, cored out of the frame A, as shown in Fig. 2.

The leaves 0, provided at both ends with the trunnions d which rest in the bearings 11 and 1), form a bottom to the frame A, when said leaves are closed as illustrated in Fig. 1. The end of each of the leaves O next to the bearings b'is provided with an upward projecting lug 6, Figs. 1 and S, which has extending therefrom the pin 6, said pin and lug forming an integral part of the leaf O.

The bar D, of essentially the form shown in Fig. 6, is provided at the top with the pin f, projecting from the face and forming an integral part thereof, and has at the bottom the dogs or ears f. The holes D, in the bar D, receive the pins 6' of the lugs cand when the leaves are in a vertical position or open to their fullest extent the ears f come in contact with the trunnions d and prevent said leaves from turning completely over.

The locking-bar E, Figs. 1 and 7, is provided at the base with the flan ge E which rests upon the top of the bearings b, when said bar is in place between the end of the frame A and the bar D. Projecting from the locking-bar E are the guidesF],whichbearagainstthe barD and assist in retainingsaid barD in place. Screwed or pivoted to the locking-bar E is the segment F, having a serrated edge and a pin for rotating the same. In the segment F is the slot F into which the pin f of the bar D is received. The screw Gpasses through the opening G in the frame A and secures the locking-bar to the end of said frame. It will now be readily seen that, by rotating the segment F, the bar D will be reciprocated between the lugs e and the guides E and at the same time open or close the leaves of the register accord ing to the direction in which said segment F is moved. hen the leaves are closed the outside edge of one outer leaf bears on the underside of the flange a, each successive leaf overlapping the next until the opposite outside edge of the outer leaf rests on the flange a. A portion of one of the leaves O is broken away in Fig. 1 to show a top view of the bearing 1). The trunnions d which rest in the bearings b extend through the openings 0 and when the bar D is in place, over the trunn1ons at the opposite end of the leaves 0, said leaves are held securely in place.

WhatI claim as my invention and desire 5 to secure by Letters Patent, is

1. In a hot air register, a series of leaves provided with trunnions at opposite ends, the lugs e and pins e; the frame A having the flange a and the bearings 12 and b, said bear- Io ings b communicating with the openings c;

and the reciprocating bar D having the piu'f and the downwardly projecting ears f, with openlngs to receive the pins 6, in combination with the locking-bar E and slotted segment 15 F, said locking-bar being provided with a iiange at the'base, theguidesE and secured to the end of the frame A, in the manner substantially as and for the purpose set forth;

FREDERICK BURMEISTER.
