JOHANNES ALEXANDER KRUSEMAN, OF LISSE, NETHERLANDS.
SPECIFICATION forming part of Letters Patent No. 718,850, dated January 20, 1903.
Application filed June 10, 1901. Serial No. 63,990- (No model.)
To all whom it may concern:
Be it known that I, J OHANNES ALEXANDER KRUSEMAN, a subject of the Queen of the Netherlands, residing at the city of Lisse, in the Netherlands, have invented new and useful Improvements in Cycle-Saddles, of which the following is a specification.
My invention relates to a sanitary saddle for cycles and motor-cycles according to anatomical principles.
My invention consists in a saddle in which an elastic air-tube enveloped in a knitted or like elastic fabric is placed to a base-plate and then so stretched over with a firm material that the saddle is divided in the middle by a deep air-groove into two parts.
In the accompanying drawings, Figure l is a sectional view of the saddle of the invention, and Figs. 2 and 3, respectively, a front and a back view of the same. Fig. 4 is a top View of the saddle on a smaller, scale.
dis a base-plate of a form corresponding to that of the saddle and having attached to it a plate 1), upon which is placed an india-rubber tube 0, adapted to be inflated with air. The india-rubber tube 0 is enveloped in an open knitted or like fabric cl, which can stretch out within certain limits and permit the tube when carrying a load to bend to some extent around the edge of the plate, but without being turned right around the same. Upon the fabric cl is placed a sheet g, of leather, over this a pad 71., and outside over the whole a covering e, of leather or other suitable firm material, which is stretched to bring its edge between the two plates a and b. The several fabrics or materials are placed above the india-rubber tube 0, and these tubes also are at the middle w of the saddle drawn downward toward the plates at b by means of a curved metal plate f, attached to the base plate by screw-bolts. In this way a deep groove is formed from front to back of the saddle.
The saddle has the great advantage that by its construction it is perfectly sanitary. The india-rubber tube only can stretch outward within the limit of the knitted or like fabric d, and otherwise it follows all movements of the rider, because the tube is not fixed on the ground-plate. Further, when traveling the rider only is supported by the right and the left part of the saddle, besides the groove at the middle as, through which will be a constant current of air, so that this saddle is perfectly constructed in the way recommended by the medical profession in accordance with sanitary and anatomical principles.
-What I claim as my invention, and desire to secure by Letters Patent, is-
In a resilient cycle-saddle the combination of an inflated tube located upon the baseplate of the saddle, with a stiff groove extending throughout the length of the saddle, and adj ustably secured to the base-plate by means of screw-bolts, and with a covering fastened to said base-plate and held at the groove, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
