.vania, have invented certain Improvements in Rope Sheaves and Supports, of which the following is a specification.

This invention relates to certain improvements in carriers and supports for the sheaves of a drag scraper system and espe-.

cially to the support for the sheave at the opposite end of the piling floor from the operating mechanism, and around which passes the traversing rope which is connected to the scraper. The object of the invention is to provide means for properly supporting a balanced sheave and which will allow the sheave to be turned in an direction desired,

and to provide a 'suitab e support for the sheave carrier so that the sheave can be bodily raised or lowered as desired.

In thev accompanying drawing:

Figure 1 is a side view illustrating my improved sheave carrier and support;

Fig. 2 is a plan view; and

Fig. 3 is a perspective view of the upper portion of the support.

1, 1 are posts spaced a given distance apart. These posts in the present instance are I beams although they may be of other shapes if desired. 2 is a transverse beam ex-. tending from one post to the other, and this beam is also made of an I beam and is clamped to the posts by plates 3 which extend over one of the flanges of each of the beams and are secured to the flanges of the transverse beam by bolts 4, so that on loosening these bolts the transverse beam 2 can be bodily raised and lowered as desired, and on tightening the bolts the beam can be held rigidly in position on the posts. The beam 2 is only raised and lowered when it is desired to materially increase or decrease the height of the pile of material on the piling floor. The beam may be raised and lowered in some instances by hand or by hoists or winches (Fig. 1) carried by the posts 1, the

. cast metal, in the present instance, and the slot 8 in this slide conforms to the shape of one edge of the beam, and in order to secure this slide 7 to the beam I provide one or more bolts 9 which may have nuts thereon or cotter pins as desired, and the beam may have aseries of holes in the web so that the slide can be adjusted on the beam and the pins pass through the holes in the web.

Pivoted tothe slide 7 by a transverse pivot pin 10 is a block 11, and pivoted to the block by a vertical pin 12 is a body section 13 of the sheave carrier. By'this construction the body section can be moved laterally on its pivot pin 12 and the block 11 can be moved vertically on' its pivot pin 10. 14 is a sheave mounted on a vertical pivot 15 carried by side members 16 which are coupled by bolts 17 to the rear block 18 connected to the body section by a longitudinal swivel bolt 19. By this construction the sheave can swivel on the body section. In order to balance the sheave I secure to the body section a bar 19 the bar and may be properly weighted to balance the sheave. By this means the sheave is kept in the horizontal position and tends to prevent the chafing of the r0 e in passing around the sheave. Thus it wi 1 be seen by the above construction that the sheave itself is free to turn on its swivel and can be moved laterally with the body section on a bolt, and the body section and this block can swivel or can be moved vertically on the bolt 10, while the slide can be adjusted longitudinally and the beam can be vertically adjusted on its posts.

I claim:

1. The combination in a sheave carrier and support, of two posts; a beam vertically adjustable on the posts; means for securing the beam in position; a slide mounted on the beam and capable of longitudinal adjustment thereon; and a balance sheave mounted on the slide.

2. The combination of a support; a slide adjustably mounted thereon; a block connected to the slide by a horizontal bolt; a sheave carrier having a body portion connected to the block by a vertical pivot; a sheave frame swiveled to the body portion; and a bar secured'to the body portion and projecting rearwardly and carrying a balbody portion to the block; a sheave and a ance i ht, frame therefor; a. longitudinally arranged 3. The combination of a transverse beam; swivel bolt connecting the frame to the body 1 supports therefor; a slide mounted on the portion; and a bar extending rearwardly 5 beam; a block; a transverse pivot connecting from the body portion and havinga Weight the block to the slide; a carrier having a. for balancing the sheave. body portion; a vertical pivot connecting the WILLIAM E.
