COUPLING FOR ROLLER-BEAMS AND THE LIKE.

To all whom it may concern:

Be it known that I, IVILLIAM I-I. GoLo- SMITH, J r., of Biddeford, in the county of York and State of Maine, a citizen of the United States, have invented a new and useful Improvement in Couplings for Roller- Beams and the like, of which the following is a specification.

In machine of the roving frame class the roller beams have been coupled or joined by coupling plates between the samsons or legs of the machine without any especial floor support. The result has been that owing to the weight of the overhang and the parts supported thereby, the ends of the beams have tended to sag somewhat so that the frame as a whole has not been level. This has resulted in a slight deviation of the axes of the rolls from a true axial line. Such a deviation must result in unnecessary wear to the rolls, and those skilled in the art will also recognize that the product will notbe uniform owing to the variation in the angle of delivery of the roving. I Vhile this variation will be slight it will be sufficient to cause considerable trouble in the later operations in which the roving is concerned.

My invention consists in providing the samson top with two uprights having a recess between them, these uprights forming the coupling or plate by which the ends of two beams are coupled, the beam ends setting into the recess and being bolted or otherwise attached thereto.

It must be remembered that in a roving frame or the like absolute accuracy of construction is essential, especially when a number of separate revolving parts must be so supported as to rotate on the same axial line and such accuracy can only be economically attained by machine work. The construction below described lends itself to finishing of this character as all the parts may be set against guides in a milling machine and milled so that all the samsons of a given machine or sets of machines will be identical and interchangeable so far as this fea ture is concerned.

Much of the expense of machines of this class is due to the fitting of the various details to what broadly speaking may be termed the main frame of the machine and the present invention is in the line of simplifying the construction, so that there will Specification of Letters Patent.

be less hand Work and more machine work with better results.

" My invention will be understood by reference to the drawings in which the upper portion only of a samson is shown.

Figure 1 is a plan and Fig. 2 is a side elevation of a portion of a samson constructed according to my invention, Fig. 3 being a section on line 33 of Fig. 2 showing the samson in side elevation.

The upper part of the samson is shown at A. Its base may be constructed in any convenient way whereby it will serve as a firm support for the weight it carries. Its upperend is provided with the usual ribs or strengthening portions a and may be otherwise constructed in cross section as seems best. It is provided with a U-shaped recess formed by the uprights B and C each of which is milled out to form a shoulder b, c to receive the lower edges of the ends of two sections of the rail which are to be coupled at the samson or to receive the lower edges of the rail if it is to support an intermediate portion thereof. The upright B as shown has two holes Z2 b to receive pins 6 and the upright C has lateral projections 0 c and is provided with holes to receive bolts D.

E, E are the ends of two adjoining sections of the rail. The lower edges of the ends of these sections being properly milled, are brought together on the samson and each is pinned to the upright B and bolted to the upright O, a recess or opening C being provided in the samson to allow the bolts to be put into place. The space between the uprights B, C, allows the nuts to be properly screwed upon the bolts. It will be seen that each end of each rail is thus given proper support and that if the samsons are sufliciently near together there can be no sagging of the ends of the sections of the rail and consequently no tendency of the parts supported by the rail to get out of perfect alinement.

While this construction is especially applicable to the supporting of the ends of rail sections in a roving frame it is applicable to other uses.

IVhat I claim as my invention is In a roving machine or the like, the combination with two alined rail sections having extended lateral bearing faces and arranged with their ends adjacent one andisposed bearing faces engaging the lateral bearing faces of'both said ends and oppositely disposed shoulders each in engagement with the lower side of both of said Copies of this patent may be obtained for five cents each, by addressing the ends, and attaching devices for directly securing both of said ends to both of said uprights With said bearing faces in engage nient, substantially as described.
