PATENT OEEIcE.
ROLLIN I-I. WHITE, OF CLEVELAND, OHIO, ASSIGNOR TO THE W'HITE SEWING MACHINE COMPANY, OF CLEVELAND, OHIO, A CORPORA- TION OF OHIO.
CROSS-HEAD.
SPECIFICATION forming part of Letters Patent No. 753,024, dated February 23, 1904.
Application filed May 21, 1903.
To all whom, it may concern: 7 I
Be it known that I, ROLLIN H. WHITE, a citizen of the United States, residing at Cleveland,
in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Cross-Heads, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
The invention is intended primarily as an improvement in the means for connecting an engine cross-head with the piston-rod and connecting-rod, respectively, the object being to make these connections cheaply, easily, and
effectively. g
The invention may be here summarized as consisting in the combination of parts hereinafter described, and pointed out definitely in the claims.
In the-drawings, Figure 1 is a central longitudinal sectional view of a cross-head embodying the invention. Fig.2 is a central longitudinal sectional view in a plane at right angles to the sectional plane of Fig. 1, and Fig. 3 is a plan view with the piston-rod cut of just above the top of the cross-head.
Referring to the parts byletters, A represents a cross-head which in the form shown is cylindrical incross-section. It should be understood, however, that this form of the cross-head is not at all material to the invention. In one end of the cross-head is the recess a for the reception of the end of the connecting-rod C. In the sides of the cross-head are two tapered holes a a which holes are in alinement, and the smaller end of the hole a is a trifle larger than the larger end of the hole a.
B represents the connecting-rod pin,which has a cylindrical portion 6, this being the part on which the end of the connecting-rod is pivoted, and this pin has also, on opposite sides of this cylindrical portion, tapered portions 5 6 which are respectively fitted to the holes a (f. A screw D screws longitudinally down through the cross-head into one of these tapered holes a m The inner end of the screw is made conical, as d. In the pin B there is a tapered hole Z into which the conical end of the screw D will project when the pin has been Serial No. 158,063. (No model.)
passed through the holes a" a as far as it can be conveniently by hand, and the conical end of the screw D at this time engages with that side ofithe tapered hole 6 which is nearest the small end of the pin. Therefore by screwing the screw D downward it draws the pin B lengthwise until its tapered portions are tightly wedged in the tapered holes in the cross-head.
In the embodiment of the device shown in the drawings two screws D are shown, and the pin B has two conical holes like the hole 6 The unscrewing of the screw D is prevented by a locking-nut 61 The pin is thus very easily removed when desired, and, moreover, the holes in the cross-head through which it passes are tightly plugged. This feature of the invention is capable of being used in devices where the member A, which has been herein referred to as the cross-head, is used as a piston-as, for example, in certain types of engines. In such cases the fact that the holes a a are tightly plugged is of great advantage.
E represents a piston-rod which is screwed 1 into one end ofthe cross-head. In the threaded part of this rod a longitudinal groove 6 is formed.
G represents a locking-washer which embraces the piston-rod and has an inwardly-extended tongue g, adapted to engage in the groove 6, and also a downturned tongue g,-
adapted to engage in a hole a in the end of the cross-head. I
F is a lock-nut on the piston rod. The piston-rod having been screwed into the crosshead as far as necessary, (during which time the locking-washer is held out of engagement with the cross-head,) the lock-nut F is then screwed down, so as to carry said lockingwasher against the end of the connecting-rod, with the tongue g in the hole a So long as this tongue does so engage in that hole any turning of the piston-rod is impossible.
The feature of the invention last described is also applicable to pistons or any other reciprocating member not specifically a cross ing paragraph furnishes a convenient connection between the piston and its rod; but it is no part of the present invention, and any other suitable connection may be used in its stead. Having described my invention, I claim 1. The combination of a reciprocating member having, in its sides, two alined tapered holes, and a connecting-rod, with a pin having a cylindrical portion which passes through the connecting-rod, and having, on opposite sides thereof, two tapered portions which. are fitted to the holes in said member, and having also a transverse tapered recess 6 and a screw having a conical point which screws through the said member and engages in the tapered recess in the pin, substantially as specified.
2. The combination of a reciprocating mem-
