REGISTER.

SPECFICATION forming part of Letters Patent No. 721,106, dated February 17, 1903.

Application inea April 19,1902.

To a/ZZ whom it' may concern:

Be it known that I, PETER S. STAUFFER, a citizen of the United States of America, residing at Springfield, in the county of Hamp# den and Commonwealth of Massachusetts, have invented a new and useful Register, of which the following is a specification, the same being an improvement on my invention for which Letters Patent No. 679,789 were issued August 6, 1901.

My invention relates to improvements in hot-air registers, in which peculiarly-constructed braces and hangers, resilient lugs for the operating-pins, slides having roller-bear,- ings, &c., are employed, all as hereinafter fully described, and especially pointed out in the claims; and the objects of my improvement are, first, to prod uce'a register of light weight, but rigid,V and strong construction, the parts of which can be easily and quickly assembled; second, to provide means for tightly closing the shutters in a positive manner; third, to afford easily-operated means for working said shutters to open or close the same either in pairs or all together when arranged in sets of four, as shown; fourth, to

furnish devices for compensating for wear incidental to frictional contact between certain of the operating parts, and, fifth, to provide a register embracing the advantages above set forth. I attain theseobjects by the means illustrated in the accompanying drawings, in which- Figure lis a plan view of one end of my register, showing the operating parts as viewed from above; Fig. 2, an under side View of said register, the center transversely of the shutters being broken out; Fig. 3, an elevation of the working end; Fig. 4, a vertical section looking toward said working end, showin g two,

of the shutters open; Fig. 5, an elevation of the left-hand side; Fig. 6, a plan view of one of the resilient lugs; Fig. 7, a side view of said lug; Fig. 8, a perspective view showing one end of one of the shutters, with the slots in kwhich the lug is to be received; Fig. 9, a perspective view of the lug; and Fig. l0, au enlarged view of the under side of one corner of the register, parts being broken away to Serial No. 103,713. (No model.)

better illustrate the method of inserting and retaining the resilient lugs in place.

Similar figures refer to similar parts th roughout the several views. 1

A plate 10, which forms the top of the register, has perforations 11 therein, and two hangers 12, preferably in the form of angleirons, are secured to the under side of said plateat opposite ends by screws 13. Shutters 14, preferably having elevations 15 to fit within the plate-perforations 11 when saidshutters are closed, are hung in the register-frame in the manner hereinafter explained. I prefer to make the plate,'hangers, and shutters, also the braces 16, of sheet metal in order to secure light-weight, the manner of construe tion giving therequired strength and rigidity. Four shutters 14 are shown; but the number is not imperative and may be departed from. The braces 16, which constitute essential parts of the frame, are preferably formed of double thicknesses of metal rolled over at the top to form holders 16a for the rods 17, and on both ends of each brace are ears 18, which are adapted to pass through openings provided for their reception in the vertical sides of theV hangers 12 and to be turned over against the outsides of said sides, thereby securing said braces in place. Each brace is further supported by a rod 17, which passes through the rolled top or holder 16a into suitable openings in the hangers 12. Portions of the top of said brace at the ends are cut away, as best shown at 19 19, Fig. 5, and

each shutter 14 is provided with rolls 20, which operate in said openings on a rod 17. A slot 21 is cut in the inside face of the roll 2O at the working end of the shutter, and a downwardly-turned lip 22, formed on said shutter opposite said rolls, has a slot 23 therein opposite said slot 2l. It will now be seen that the shutters 14 are so hung that they can swing freely on the rods 17 in the frame, consisting of the braces 16 and connected partsa frame which is strong and rigid without being heavy and cumbersome. -l

Slides 24 and 24a are provided with rollers 25, which operate in slots 26 in one of the hangers 12, said slides reciprocating against the inside face of said hanger. Each of these slides is provided with a lfoot-piece 27, the shank of which extends through a slot 2S in the plate 10. The foot-pieces 27 rise above the upper surface of the plates 10 and are the medium by which the

slides

24 and 24 are reciprocated. Projecting forwardly from the

slides

24 and 24 are pins 29, corresponding in number to the number of shutters.

A resilient lug 30 is provided for each shutter 14 and is preferably formed by bendinga long thin piece of metal over upon itself at one end, then extending the same downward at an acute angle, and finally projecting the free end 30a in a direction parallel with the straight part, or said free end may be turned upward slightly, for the reason hereinafter set forth. The free ends 30 of the lugs 30 furnish the bearing-surfaces for the pins 29. Each lug 30 is notched or shouldered, as best shown in Figs. 6 and 9, so as to provide a comparatively long projection 30b at one end and a short projection 30 at the other end, these projections being adapted to enter the before-mentioned shutter-

slots

21 and 23. A shoulder 30, adjacent to the projection 30, is adapted to bear against the lip 22 when said lug is in position. The lugs 30 are located just inside of the

slides

24 and 24 and constitute an efficient and valuable feature of my invention.

The general method of assembling the parts comprising this register will be understood from the foregoing description; but before the rods 17 are inserted in the rolls 20 at the working end of the register it is necessary to place the resilient lugs 30 in place, which is done in the following manner: First insert the end 30" of a lug 30 into the corresponding holder-slot 2l and push said lug to the right, as shown at the right handof Fig. 10, until the end 30c can be introduced into the correspondinglip-slot 23. Then move the lug to the left until the shoulder 30l bears against the lip 22. The rod 17 is then passed through the roll 2O behind the end 30", thus holding the lug against the lip 22 and securing the same firmly in place.

Assuming that the shutters are closed, the operation of my device is as follows: In order to open two of the shutters, as shown in Fig. 4, force the slide 24a toward the outside or to the left, which movement withdraws the pins 29 from beneath the ends 30a of the lugs 30 and permits the two shutters which were supported by said ends to drop or open by gravity. The other two shutters may be opened in a similar manner by actuating the slide 24 inwardly or to the left. If desired to open the four shutters at once, the slide 24 alone is actuated inwardly, contacts with the slide 24, and withdraws the supporting-pins from beneath all of the ends 30, To close the shutters, (shown open in Fig. 4,) it is only necessary to actuate the slide 24a toward the center, which movement will also close all of the shutters in case they are open, as said slide will then contact with the slide 24. The two left-hand shutters may be closed by means of the slide 24 without affecting the other shutters.

From the foregoing it will be readily seen that the slide 24 opens all of the shutterswhen actuated toward the center and closes two of them when moved to the left,while the slide 24 opens two only or closes them all, according to the direction in which it is actuated. In closing the shutters the pins 29 first bear against what may be termed the solid parts of the lugs 30, then against their inclined surfaces, and finally come to rest beneath the ends 30a. By inclining the ends 30 upwardly the pins 30 are brought to rest beyond projections formed by the lower angles of the lugs, and there is thusno danger that said pins will slip back without the application of force. These lugs afford means for operating the shutters in a positive manner without unnecessary shock or jar, and they also serve to compensate for wear, so that there is no looseness or backlash, and the rollerbearings for the slides permit the same to be operated easily.

Modifications in the shape of the lugs 30-and in the method of attaching them to the shutters may be made without departing from the nature of my invention.
