HARRY C. LINDSLY, OF KANSAS CITY, MISSOURI.
HEAD-BLOCK.
Specification of Letters Patent.
Patented Jan. 2, 1906.
Application filed February 29, 1904- Serial No. 195.864.
To all whom, it inrty concern.-
Be it known that I, HARRY C. LINDsLY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Head-Blocks; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My present invention relates to head-blocks for pile-drivers, and has for its object to provide a device which will be simple and economical in construction and will embody points of novelty and utility not heretofore known.
The principal object of my device is to provide means for guiding the auxiliary rope used for picking up the piles before placing them in the leads, thereby obviating the tendency of said rope to slip from the sheave-wheel when it is extended at an angle thereto.
A further object is to provide means whereby the tendency of the hammer-rope to leave its sheave is obviated.
Further objects of my invention are to provide improved details of structure hereinafter described, and pointed out in the claims, reference being bad to the accompanying drawings, forming part of this specification, in which like reference-numerals refer to like parts throughout the several views, and in which Figure 1 is a side elevation of my device. Fig. 3 is an end elevation of same. Fig. 4 is a reduced perspective view of same.
Referring more in detail to the drawings, 1, 2, and 3 are standards, preferably formed by having metal webs 1, 2, and 3, faced with bands 1 2", and 3", the said bands extending from each side of the webs and forming a substantial base upon which the standards may rest, and, further, forming an extended bearing-surface for carrying a series of shafts, as will presently be described, while the webs give a rigidity and strength to the standard. Said standards may be set a desired distance apart and secured together by means of bars 41 and 5, said bars being secured to the standards by means of bolts 4* and 5, which pass through perforations in said bars and the lips of bands 1, 2, and 3, which extend beyond bands.
the webs of the standards. The upper sides of bands 1", 2 and 3 are provided with cutout portions 6 and 7, which form the lower members of a journal-box in which are positioned shafts 8 and 9. Fitting over shafts 8 and 9 and rigidly secured to said bands are the upper members 10 and 11 of said journalboxes. Mounted on shafts 8 and 9 are sheavewheels 12 and 13. 14 represents plates'adjustably secured to the rear ends of said standards by means of bolts 27 and 28, which pass through slots 29 and 30 and through said Plates 14: are provided at their outer ends with curved members 15. Positioned in curved members 15 is a shaft 16, on which is mounted a small sheave-wheel 17. At the front of each of said standards is an arm 18, extending upwardly and outwardly therefrom. Secured to the upper faces of said arms is a plate 19, having an ear 20, which is provided with a concaved portion 21. Secured at their upper ends in the outer ends of ear 20 and at their lower ends in a base 22 of said standard are a pair of shafts 23 and 24, on which are loosely mounted rollers 25 and 26.
In the operation of my device the standards are joined in the manner described'and mounted on the top of a pile-driver. A rope secured at one end to the drum of an engine is run over the smaller of the two large pulleys and between the rollers on the front end of the frame. The outer end of the rope may then be attached to a pile at a point at any angle from the front of the pile-driver and drawn up in position to be set, the rollers serving to guide the rope to prevent its leaving its seat on the sheave, as it would ordinarily do when a head-block of the usual construction is used. When the pile has been set in the leads, the rope is removed therefrom and work of driving it into the ground is begun. In doing this a heavy hammer attached to a rope passing over the larger of the sheave-wheels and attached to the drum is utilized, the hammer being drawn up by winding the inner end of the rope around the drum of the engine and then releasing it, allowing the hammer to fall, striking the head of the pile. The hammer in falling draws the rope rapidly over the sheave, and as the hammer stops suddenly there is a tendency for the rope, which is necessarily loose, to fly up and leave its seat in the sheave. To obviate this, I place a small sheave or rooster on the rear of the frame, directly in line with the hammer-sheave and close enough to it to prevent the escape of lIO the rope, but not so close as to prevent free movement thereof.
I do not wish to be understood as limiting myself to the exact details of structure herein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.
Having thus described my invention, whatI claim as new therein, and desire to secure by Letters Patent, is
1. In a head-block, a series'of standards, means for joining said standards to form a frame and pulleys carried by said frame.
2. In 'a head-block, a series of standards, means for joining said standards to form a skeleton frame, a shaft mounted in boxings on said standards, and a pulley mounted on said shaft between two of said standards.
3. In a head-block, a series of standards, bars joining said standards and securing same together to form a frame, cut-out portions in said standards, a shaft mounted in said cut-out portions, plates, having semicircular portions therein, secured to said standards and forming, with the cut-out portions in said standards, boxings for said shaft, and a pulley mounted on said shaft.
4C. In a head-block, a series of standards, means for joining said standards to form a frame, arms on the ends of said standards, means on said arms for carrying rollers, rollers carried by said means. and pulleys mounted in said frame. I
5. In a head-block, a series of standards, means for joining said standards to form a frame, arms on the ends of said standards, seats on said standards adjacent to and extending at an angle with said arms,a plate secured to the outer ends of said arms, and rollers mounted between said seats and said plate.
6. In a head-block, a series of standards,
means for joining said standards to form a frame, arms on, and extending at an angle with said. standards, seats on said standards, at the bases of'and extending at an angle with said arms, a plate secured to the tops of said arms, shafts mounted between said seats and said plate, and rollers mounted on said shafts.
7 In a head-block, a series of standards forming a suitable frame, arms on said standards, a plate secured to said arms, an ear on said plate, shafts having one of their upper ends carried by said ear and the other by a suitable base on said standard, and rollers mounted on said shafts.
8. In a head-block, a series of standards forming a suitable frame, arms on said standards, a plate secured on said arms, an ear hav ing a concaved portion, on said plate, and rollers mounted between said ear and a base on said standard.
9. In a head-block, a series of standards forming asuitable frame, arms on said standards extending upwardly and outwardly therefrom, a seat on said standards extending from said arms and in a plane parallel with the upper faces of said arms, a plate secured to the upper faces of said arms, an car on said plate, a series of shafts mounted in said ear and in said seats, and rollers carried by said shafts.
10. In a head-block, a suitable frame, pulleys journaled on said frame, plates having slots therein adjustably mounted on the rear of said frame by means of bolts passing through said slots and into said frame, means on the outer ends of said plates for carrying a'shaft, a shaft carried by said means, and a pulley mounted on said shaft.
In testimony whereof I aflix my signature in presence of two witnesses.
