TRACK-SUSPENDER.

Specification of Letters Patent.

Patented July 23, 1912.

To all whom it may concern:

Be it known that I, ARTHUR M. HARRING- TON, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Track- Suspenders, of which the following is a specification.

My invention provides improved means for suspending tracks adapted for carrying trolleys, such as are used for translating traveling hoists and other purposes, and particularly for suspending I-beams by engagement with the top flanges thereof so that the bottom flanges can be used as unobstructed ways for the wheels. Its primary purpose is to provide a simple, convenient and firm suspending means. 7

In the accompanying drawings, Figure 1 is an elevation of a track suspender engaging an I-beam in accordance with my invention; Fig. 2 is an enlarged sectional view of a section of my improved suspender connected to an I-beam; and Fig. 3 is a perspective view illustrating the features by which the suspender is engaged to the I- beam.

As illustrated in the drawings, the suspender comprises the inclined tension members 1 having the angularly disposed horizontally extending bearings 1 which are engaged to an overhead beam 2 by the bolts 3 and the angularly disposed vertically extending parts l having the inwardly extending flanges 1 thereon. An I-beam 4 has its top flanges 1 engaged between the upright parts 1 and resting on the flanges 1 which conform with the under surfaces of the I-beam flanges and provide bearings therefor. A filling piece or block 5 rests upon the top of the beam 1 and bears against the parts 1*, such block having therein a longitudinal channel 5 with its bottom surfaces 5 inclined downwardly from the center. A bolt 6, bent to conform to the bottom of the channel 5*, extends through holes 1 in the parts 1 which are drawn up against the flanges 1 and the block 5 by turning the nuts 6. As the bolt 6 is brought under tension by the action of the nuts 6?, it tends to straighten, thus pressing the block 5 against the top of the I-beam and clamping the flanges 1 and 4 firmly together.

This construction has the advantages of simplicity and security, the parts being inexpensive, readily assembled and dissociated, and providing a firm connection with the top of the I-beam and a rigid support therefor without obstructing the lower flanges 4 thereof.

Having described my invention, I claim:

1. A suspender comprising, in combination with a track having flanges thereon, tension members having parts disposed beneath said flanges to support said track and means for drawing said flanges and parts together transversely to their bearing sur faces.

2. A suspender comprising, in combination with a track having outwardly extending flanges thereon, tension members having inwardly extending bearings disposed beneath said flanges whereby said track is supported, and means comprising a block and a bolt whereby said track is pressed downwardly to clamp said flanges and bearings together.

3. A suspender comprising, in combination with a track having top flanges thereon, tension members having bearings disposed beneath said flanges whereby said track is supported, and means comprising a device with oppositely inclined surfaces supported by said track between said members and a bent bolt passing through said members in en gagement with said surfaces whereby said flanges and bearings are clamped together.

4. A suspender comprising oppositely inclined tension members having upright parts and flanges, a track engaged between said upright parts and bearing on said flanges, a block disposed on said track between said upright parts, said block having bearing parts inclined downwardly toward said upright parts, and a bent bolt passing through said upright parts and engaging said bearing parts whereby said tension members and track are clamped together.

In witness whereof I have hereunto set my name this 23rd day of March, 1912, in the presence of the subscribing witnesses.

A. M. HARRINGTON.
