ROBERT HERMANN THIELEMANN, OF LICHTENSTEIN, GERli/IANY.`
SPECIFICATION forming part of Letters Patent No. 542,661, dated July 16, 1895. 4 Application filed July l'7J 1894. Serial No. 517,824- l (N0 model-l To rif/ZZ whom, it may con/cern.-
Be it known that I, ROBERT HERMANN THIELEMANN, a subject of the Kin g of Saxony, and a resident of Lichtenstein, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Furniture, of which the following is a full, clear, andV exact description.
The present invention consists of a device in connection with tables, desks, and the like,
' by means of which the feet and legs of the occupant may be kept warm.
It is Well known that many people whose vocation necessitates their sitting at a desk or table for the greater part of the day sulfer from cold feet during Winter, a fact which besides personal discomfort generates also a number of diseases. The disadvantage is 0bviated by means of the present invention, which comprises a combined table or desk,
stool or chair, and device for warming the feet and legs arranged underneath the said table or desk before the stool or chair in the manner hereinafter more particularly described; and in order to make this specification more easily intelligible reference is had to the accompanying drawings, in which similar letters denote similar parts throughout the several views.
Figure l is a side elevation of the device; Fig. 2, a horizontal section on the line a. b, Fig. 1; Fig. 3, a vertical cross-section through the desk; Fig. 4, a plan of the desk-slab; Fig. 5, a detail side elevation of the mechanism Y for adjusting the position of the desk-slab;
Fig. 6, a plan of Fig. o with the retaining springs for the slab in position in the rails thereof; Fig. 7, a similar plan showing the said springs disengaged. i
The device consists of the outer structure D, advantageously in the form of a desk having an interior lining of zinc Z and anintermediate layer of felt F. Within the shell G, which is open at the front part Where the occupant is intended to sit, is a second casing of zinc Z', both shell and casing being covered in by a top plate or covering C. The interior casing Z has covering ot' cane R, woven in the usual manner and stretched in a metallic frame R', corresponding in shape and size to thev interior conguration of the said casing. The side of this interior casing,
against which the chair T is situated, only extends from the base-plate up to the seat ot' the chair, so that the two casings Z and Z inclose an intermediate space having the plan form of three sides of a square, Fig. 2, the said space being closed in on the chair side by the strips T3 T3. Thus the occupant' of the chair can sit on the same with his feet 6o and legs extending into and resting on the i tioor of the interior of the casing Z', direct contact with the zinc walls being prevented by the cane-covering R.
Within the space between the bottoms of the exterior and interior casings Z Z a ring of steam-distributing nozzles K, having a steamsupply pipe D, lead upward and through the top covering C to a stop-valve A and then outward, Fig. 1, in any convenient direction. 7o Thus a steam-jacket is formed around the chamber -in which the occupant of the chair has his legs. Upon the top plate C and cornmunicating with the interior of the steamjacket is a safety-valve S, While in the baseplate a valve V is arranged, having a protecting-cap Eand operated by means of any suitable lever system St, Figs. l, 2, and 3, by a button or handle arranged on the top of the plate C. A thermometer This arranged upon 8o the latter plate by which to control the temperature ot' the steam-jacket. The valve V is for letting oft the condensed Water from the steam-jacket, and when employed the cap E should lirst be removed.
On an extension T of the base-plate the chair T is arranged, having folding seat T2 adapted to fold onto the back ot' the chair so as to facilitate getting into position before the desk. The valves and other devices on 9o the plate or covering C are covered by the slab of the desk P which is advantageously made adjustable and arranged in the following manner: On suitable upwardly-extending arms or brackets tif of the plate C or upper 95 part of the casing G, Figs. -l and 5, are fixed horizontally-extending arms if', Fig. 5, carrying guide rolls r r, Figs. 6 and 7, in grooves, of which rshaped rails s s are mounted to run, said rails being supported at theiriorn.0 ward ends on rolls s3, mounted on arms s?, supported on the plate C. The Writing plate or slab P is hinged at its forward ends at cc to two rails s s,which latter have theirI ends hereinafter described. At therear side of the plate-'L'. e., the side farthest from the writer two graduated sector-bars m are pivoted to the under side of the said plate P at Z, said sectors being each adapted to slide in slots of thecorresponding rail s, so that the slat can be tilted and supported at any desired angle in the substructure G by means of the setscrews n of the said rails s, which clamp the said sector-bars in any position. The slab P can further be slid backward from the occupant, as shown in dotted lilies in Fig. 1, and is arrested in its forward or normal position by means of the following device: To the arms if', Figs. 5, 6, and 7, are fixed fiat springs f,-
carrying at their free ends studs a, adapted when the slab is in its normal positien,to engage in orifices or slots e of the upwardlyextending web of the rails s s. Suitably guided on the web of the said rails is a wedge shaped sliding block g, attached by a connecting line or rod to one end of a pivoted lever 7c pivotedv to the under side of the slab I). The inclined surface of this slideblock gis adapted when drawn forward by moving the lever /c into the position shownin Fig. 7 to contact with the pin or stud z ofthe springf, and push the same back out of the slot e of the rail so that the slab P can then be pushed backward away from the occupant into the position shown in dotted lines in Fig. l. On releasing lthe lever 7c the block g will return to its original position under the pull of its spring t'. Thus,in order to push the slab back to facilitate getting into position before the desk or table, it is only necessary to pull back the levers 7c and push the slab y out, its outward movement being determined tom of which a s'titfening-ring I, having feet resting on the base-plate is provided to prevent treading through the zinc lining.
slab may then be drawn forward and the temperature within the steam-jacket regulated as desired. If deemed necessary, buttons H H may be arranged on the plate C for the reception of a covering for the knees.
Instead of steam heating any other suitable heating may be employed, although the former is advantageous.
By means of this apparatus the feet and legs of persons sitting at the desk will beheld continually warm.
I claim as my invention- 1. A desk or table, having an outer shell or substructure, an' inner chamber within said exterior shell to receive the occupants legs and feet, a covering plate common to both shell and interior casing an adjustable slab mounted on and above said cover means to adjust the same and means for heating the space inclosed between the said shell and interior casing substantially as described.
2. A desk or table having an exteriorshell and an interior chamber, a cover common to both an adjustable slab mounted on said cover, a steam distrbuter between the shell bottom and inner easing bottom, steam supply pipe to said distributer, means for regulating the steam supply and a condensed water cock arranged in the bottom of the exterior shell substantially as described.
3. A desk or tabfe, having an outer shell or substructure, an inner chamber within said exterior shell, a covering plate common to both shell and interior casing means for heating the space between said shell and interior casing, an adjustable slab, sliding rails hinged to said slab, fixed guide rolls to said rails and means for arresting said rails in their forward or normal position, sector bars hinged to said slab, and guided in slots in the rail ends and means for clamping said sectors in any position substantially as described..
In witness whereof I have hereunto set my hand in the presence of two subscribing witlleSSeS.
