Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed February 13, 1905. Serial No. 245.473.

To all wil/om it may concern.'

Be it known that I, THOMAS PODMORE, a citizen of the United States, residing at Wilkesbarre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Elevating-Trucks; 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 is an improved elevatingtruck especially adapted for use in connection with machines for molding concrete blocks and other analogous machines for conveying the blocks from the machines to the stands on which the blocks are to be dried; and my invention consists in the construction, combination,and arrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a truck embodying my improvements, showing the upper frame thereof in lowered position in full lines and in a raised position in dotted lines. Fig. 2 is a transverse sectional view of the same, taken on the plane indicated by the line c a of Fig. 1; and Fig. 3 is a detail transverse sectional view showing the construction. of the truck and also showing the construction of the traveler which rolls on the upper truck-frame.

The lower frame l of my improved truck is mounted on axles 2, which are provided with flanged wheels 3, that run on a track which extends from the molding-machine to the stand or stands on which the blocks are Bearings 11 are here shown as depending from the lower truck-frame 1 and in which the axles 2 are journaled. The sides 5 of the lower truck-frame are made of angle' metal, having inwardly-extending horizontal flanges or webs 6 at their upper sides. On the lower frame l of the truck is an upper frame 7, which is adapted to be raised therefrom and to be lowered thereon. The upper truck-frame 7 is also here shown as made of angle metal, so that the same is formed with tracks 8 on its upper side. The upper frame 7 is connected to the lower frame 1 by means of links 9, which are disposed on the sides thereof and have their upper and lower ends respectively pivotally connected to the upper and lower frames of the truck. To one end of the truckframe 1 is pivoted a tubular guide 10, as at l1. In the said tubular guide is the rear portion of a lever-handle 12, which is longitudinally slidable in the tubular guide and the lower rear end of which is connected to the vertically-movable upper truck-frame 7 by means of a link 18, the upper end of which is pivotally connected to the upper truck-frame 7 and the lower end of which is pivotally connectedto the inner end of the said leverhandle.

When the outer end of the lever-handle is depressed, the link 13 is raised, thereby causing the upper truck-frame 7 to be also raised, the links 9 permitting such vertical movement ,of the upper truck-frame and serving to also move the same longitudinally in one direction as it is being raised. Furthermore, the said links 9 coact with the lever-handle 12 and link 13 to support the said upper truck-frame in its elevated position.

On the upper truck-frame is a traveler or car 111, which isadapted to be run onto the molding-machine to receive the blocks molded by the machine and to be run from the machine onto the tracks of the upper truckframe, so that the said car or traveler when loaded may be carried by the truck to the stand where the blocks are'to be dried, the raising and lowering of the upper truck-frame facilitating the loading of the car onto the truck and the unloading or discharging of the blocks from the car when the drying-stand has been reached. The said car 14; is provided on its under side at its ends with bolsters 15, to the under sides of which are secured frames 16, in which caster-wheels 17 are mounted, the said caster-wheels being adapted to travel on the tracks 8 of the upper truck-frame.

Said caster-wheels may be provided with ballbearings or other suitable bearings to reduce friction. Said car 14 has afloor 18, supported by springs 19. The blocks are loaded on the said spring-supported floor, and the same prevents the blocks from being injuriously jarred while being carried by the car.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

IOO

member, and a link connecting the lever-handie to the upper truclvframe, for the purpose Set forth, substantially as described.

In testimony whereotl I have hereunto set my hand in presence of two subscribing witnesses.

THOMAS PODMORE.
