No. 542,955. Patented July 15, 1895.




SPECIFICATION forming part of Letters Patent No. 542,955, dated July 16, 1895.

l Application led March 8, 1895. S'erial No. 541,061- (No model.)

To a/ZZ whom it may concern.-

Be it known that I, JOSEPH J. FEELY, a citi zen of the United States, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Standards for Furniture, of which the following is a specification. i My invention relates to standards for fur- I niture, and particularly to those standards which are adjustable vertically to provide for the location at dierent heights of the piece of furniture supported thereby, and its object is to produce a device of that class which shall be simple and durable, easy of manipulation, and efficient in its action.

My improved standard is especially intended to be used in connection with schooldesks, and I have illustrated and described the preferred form of my invention for that purpose; but it may be used as well for chairs, tables, type-writer stands, and other analogous articles of furniture, as will be apparent.

In the accompanying drawings, Figure lis a perspective view of a school-desk provided with my standard. Fig. 2 is a side elevation of a detached standard. Fig. 3 is a central vertical section of the same. Fig. Aalsa transverse section of the standard on the line a: w in Fig. 2. Fig. 5 is a view similar to Fig. et, illustrating a slight modication. Fig. 6 isa detail View on an enlarged scale, showing the arrangement of the pawls and racks hereinafter described the upper part of the standard being removed. y

The letter A represents an article of furniture, in this instance a desk, supported by two of my standards B. Said standard consists of two main parts, a lower part or base a, and an upper part b, which I will referto as the adjustable part. These parts are provided with suitable lugs or ears, as shown, whereby they are secured, respectively, to the floor and to the under side of the desk. The upright arms a3 of thebase a are provided, in the form of my invention shown in Figs. l, 2, 3, and 4, with ribs a3, which, together with said upright arms, form guides between which the upper part b of the standard is adapted to slide when being adjusted.

In the modification shown in Fig. 5 the adjustable part Z) slides in grooves a4 formed in the arms a3, whereby the parts of the standard will be kept from falling apart even though the bolt (Z, hereinafter described, be removed.

The adjustable part b carries a bolt d, on which is mounted a plate c. This plate c and the part b slide on opposite faces of the arms a3, and consequently by tightening the nut tt on the bolt d the parts a and b of the standard can be firmly clampedin any position of adjustment. These parts c, d, and d', however, do not constitute the primary locking mechanism for the adjusted parts,but are supplemental to a rack-and-pawl arrangement, which consists of the racks a', formed on the inner edges of the upright arms a3 and the pawls e, pivoted preferably on the bolt el and arranged to engage said racks. The pawls e are normally kept in engagement with the racks by means of a spring e', which is preferably a rat-trap spring, and has its ends secured to the upper ends of the pawls e. A rod or wire f, attached to the loop of the spring e', extends upward on theinside of the upper part b of the standard and is bent outward at its upper end through a slot b to form a handle f. Said handle f is of such width that in order to get it into or out of the slot b" the rodfmust be brought up into a horizontal position. Consequently after the parts are assembled and the lower end of the rod is secured to the spring e, it is impossible for the rod f to be disturbed from its operative position by any amount of meddling on the part of the scholars. The length of the slot Z9 is such as to allow` a sufficient upward movement of the rodf to draw the upper ends of the pawls toward each other and thereby free their lower ends from the racks when it is desired to raise or lower the standard.

I prefer to provide the plate c on its top and bottom edges with inwardly-projecting anges c', which, in connection with the adjacent parts, completely inclose the pawls and prevent them from being meddled with. My adjusting mechanism, as above described, is provided on each of the standards which support the desk, and its operation is thought to be obvious without further description. As stated, the parts when adjusted can be tightly IOO clamped together by means of the nut d when it is desired to prevent the adjusted parts from being interfered with by the scholars, or this clamping may be omitted, if preferred. 5 If so desired the pawls e may have their bearings on a stud cast on the inside of the adjustable part b of the standard independent of the bolt d; but I prefer the construction shown, it being simpler. Furthermore the to device may, if desired, be somewhat simpli- `tied by omitting one of the racks and one pawl from each standard, and I do not intend to limit myself tothe duplicate construction. Also my invention may be modified in other 15 particulars, especially in the form of the parts a and b, Without departing from the spirit of my invention.

I claim as my inventionl. A standard for furniture comprising in zo combination a lower part or base, an upper part adjustable thereon,raclrs on one of said parts, pawls secured to the other of said parts, a rat-trap spring substantially as described secured by its ends to the pawls, and means z5 for operating said pawls consisting of a vertically movable rod connected to the loop of the spring and extending upwardly on the inside of the standard, it being bent outward at its upper end through a slot to form a handle 3o which is integral with the rod and is also wider than the slot, all substantially as described.

2. A standard for furniture comprising in combination a lower part or base provided with racks, an upper partadjustable thereon and carrying locking pawls, means for disengaging the pawls from said racks, and a plate secured to the upper part of the standard by means of a bolt and nut, orits equivalent and arranged to clamp the lower part of the standard between itself and the upper part of the standard, all substantially as described.

3. A standard for furniture comprising in combination a lower part or base provided with racks, an upperpart adjustable thereon and carrying locking pawls, means. for disengaging the pawls from said racks, and a plate secured to the upper part of the standard and arranged to clamp the upper and lower parts ot the standard together when adjusted, said plate being provided with inwardly turned flanges at its ends, whereby the locking pawls are completely inclosed, all substantially as described.
