COMBINED SCHOOL DESK AND 'SEATf SPECIFICATION forming part of Letters Patent No. 605,268, dated June 7, 1898 Application filed January 24, 1898. Serial No. 667.785. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH B. BURFOOT, a

' citizen of the United States, residing at Mobile, in the county of Mobile and State of Ala bama, have invented certain new and useful Improvements in a Combined School Desk and Seat; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combined school desks and seats; and the object is to simplify the construction and increase the efficiency without adding to the first cost and at the same time provide a novel means for removably securing the same to the floor in a rigid substantial manner, so as to practically brace it against lateral or 1011- gitudinal displacement.

To this end the invention consists in the construction, combination, and arrangement of a the device, as will be hereinafter more fully described, and particularly pointed out in the claim.

The accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my invention, as set forth in the claim at the end of this specification.

The same reference characters indicate the same parts of the invention in the several views.

Figure 1 is a perspective View of my improved desk and seat. Fig. 2 is a top plan view of one of the horizontal integral braces connecting the duplex side legs. Fig. 3 is a longitudinal section of the same.

'1 and 2 denote the duplex side legs, the lower ends of which are connected by the integral horizontal brace 3, the lower edge of which is formed with a series of arched recesses, alternating with the depending lugs 4 4 and the central socket 5.

The lower flanged feet of the legs 1 and 2, the lugs 4L 4, and the socket 5 all lie in the same horizontal plane, and from their plane faces project a series ofpointed spurs 6 6,

which may be cast integral therewith and brought to a sharp point afterward, or pointed wrought-metal brads may be inserted in .correspondingly-threaded cylindrical shank 9 of the screw 10, the upper portion of which is formed with a' countersunk collar 12 to conform to the orifice 8, and this collar terminates in a rectangular head 13, formed with a transverse slot 14 to receive a screwdriver, while the rectangular head is adapted for a socket-key or suitable key to manipulate it.

The inner Vertical faces of the legs are semicircular. in cross-section, while the lower portions of said legs, where they connect withthe flanged feet, are cast solid to insure additional strength at these points.

Of course it will be understood that the machine-thread on the shank 9 and the woodscrew thread on the screw 10 are of the same pitch, so that when manipulated up or down the threads on the wood-screw portion will travel in the same ratio as the machinethreads on the shank 9, and it will also be observed that the external diameter of the wood-screw 10 is somewhat less in diameter than the diameter of the threaded orifice 8, so that when inserted in place the wood-screw will freely pass through the orifice 8 without nating with the depending lugs4 4 and the centrally-arranged socket 5 formed with the countersunk recess7 and internally-threaded cylindrical orifice 8, the alined plane faces of IOO said legs, lugs and socket being provided with my hand in presence of two subscribing wita series fighdependiifg fSPHISGG 6ifliighcoaibingnesses. tion wit e screw orme wi e rea ed cylindrical shank 9, countersunk collar 12 JOSEPH T' 5 andrectangular slotted head 13,substantially Witnesses:
