FRED A. NEIDER, OF AUGUSTA, KENTUCKY.
PROP FOR CARRIAGE-TOPS.
SPECIFICATION forming part of Letters Patent No. 744,219, dated November 17, 1903. Application filed December 31, 1902. Serialll'o. 137,230- (No model.)
Too/ll whom, it may concern:
Be it known that I, FRED A. NEIDER, a citi zen of the United States of America, and a resident of Augusta, county of Bracken, Stateof Kentucky, have invented certain new and useful Improvements in Props for Carriage- Tops,of which the following is a specification.
My invention relates to top-props for carriages in which the bolt of the prop-joint passes through the bow.
- The object of my invention is a bolt which does not split the bow, will not turn therein, and with which the use of reinforcing-clips to prevent the bows splitting are dispensed with. This object is attained by the means described in the specification and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a carriagetop. ,Fig. 2 is a detail sectional view of a carriage-bow and the bolt embodying my inven tion upon an enlarged scale. s Fig. 3 is a de tail plan view of apart of a bow, showing the hole made therein through which the bolt is driven. Fig. 4 is a detail view of the same after the bolt has been driventherethrough. Fig. 5 is a sectional view showing the propjoint complete. Fig. 6 is a perspective View of the sleeve upon which the prop-brace fits. Fig. 7 is a perspective view of the bolt.
Referring to the parts, bolt A has two of its sides cut away at diametrically opposite points, making the bolt in cross-section substantially in the shape of an elongated rectangle. The screw-threads are left upon the sides a a. At the end a the bolt is reduced, so that its end consists of a circle of a diameter equal to the least diameter of the bolt. Bow B has a hole I) bored through it equal in diameter to the end a of the bolt. The bolt is then driven through hole b, with the longer diameter of the bolt lying parallel with the.
grain of the how. The effect of this is to spread hole 19 in the direction of the grain, while the hole in the direction counter to that of the grain is not affected. Thus there is no tendency to spread the bow apart at the grains, the expanding of the hole in a direction parallel to the grains only crowding the material in that direction and not affecting the strength of the how, but simply tightening the wood about; the bolt, so that there is no tendency in it to slip out or to rotate in the how. The
bolt not having affected the grain of the bow the splitting of the bow or to hold the bolt from turning therein. After the bolt has been passed through the bow as aforedescribed thimble O, which is interiorlyscrew- 6o threaded at its upper end, is screwed down over the bolt to bear against the bow, and split sleeve D is then placed over the bolt. Brace E is then placed over the sleeve E, and jam-nut F is brought to bear against the sleeve D, which is made slightly wider than the brace E, so that it is held firmly against the thimble O by the jam-nut F and aflords a good journal for the brace E.
What I claim is- 1. In a prop for carriage-tops, the combination of a bow, a bolt having two of its sides cut away at diametrically opposite points driven through the bow with its longer diameter in a direction substantially parallel to the grain thereof, and abrace journaled upon the bolt, substantially as shown and described.
2. In a prop for carriage-tops the combination of a bolt having two of its sides cut away'at diametrically opposite points and driven through the bow by first forming therein a hole of a, diameter equal to the least diameter of the bolt, with its greatest diameter parallel to the grains of the bow, and a brace journaled upon the bolt, substantially as shown and described. 7
3. In a prop for carriage-tops the combination of a'bolt having two of its sides cut away at diametrically opposite points, the screw-threads upon the bolt at its longer diameter, a bow with the bolt driven therethrough, the longer diameter of the bolt coming parallel to the grain of the how, a thimble upon the bolt, a sleeve adjacent to the thimble, a brace journaled upon the sleeve and a jam-nut upon the end of the bolt bearing the bow with its longdiameterparallel to the against the sleeve, substantially as shown grain of the bow to form a part of the propand described. joint, substantially as shown and described. 4. In a. prop for carriage-tops the combi- FRED A. NEIDER. 5 nation of a bow, a bolt whose cross-section is Witnesses:
a figure having a long and a short diameter BERNARD BOWEN,
