SAFETY-SUPPORT FOR LOCOMO'IIVE CROSS-HAD GUIDES.
\ Application filed March 13, 1918. l Serial No. 222,156.
To all whom t may concern:
Be it known that I, HARRY A. HOKE, a citizen of the United States, and residing at Altoona, county of'Blair, State of Pennsylvania, have invented certain new and useful Improvements in Safety-Supports for Locomotive Cross-Head' Guides, of which the following is a specification.
The present invention relates to steam locomotives and more particularly to supplemental means for supporting the front ends of the cross-head guides in case the main supporting means should fail.
The objects and features of novelty of the invention will be apparent from the description taken in connection with the drawings in which:
Figure 1 is a side elevation of a portion of a locomotive certain parts being broken away in order to illustrate the present invention;
Fig. 2 is an elevation of the rear cylinder head;
Fig. 3 is a sectional detail taken substan* tially on the line 3 3 of Fig. 1;
Fig. 4 is al sectional detail taken substantially on the line 4 4 of Fig. 5 illustrating the invention as applied to'existing locomotives; land Fig. 5 is a longitudinal sectional view taken substantially on the line 5--5 of Fig. 4.
Referring to Figs. 1 to 3 of the drawings it will be seen that the rear cylinder head 9 `is provided with the brackets 10 and 11 which project in an axial direction therefrom. The outer surfaces 12 and 13 of these brackets are arranged to provide seats for the front ends of the cross head guides 14 and 15. These seats are provided on the outer sides of the brackets so that the guides may be secured thereto for adjustment in a radial direction with respect to the center line of the cylinder to take up the wear between the cross heads and the guides. F01 this purpose shims 16 and,17 may be interposed between the seats and the ends ofthe guides and the guides clamped to thebrackets by means such as the bolts 18 and 19.
With the above described construction if the bolts 18 and 19 failed, due to the vertical thrust of the cross head, the guides might be displaced so as to cause a serious accident. The present invention consists in the provision of means for overcoming this defect and for this purpose an abutment is provided radially outside the ends of the guides Speccation of Letters Patent.
Patented July 2, 1918.
which acts as a supplemental supporting means for the same in case the bolts break. In the embodiment illustrated, the brackets 10 and 11 are formed with the recesses 20 and 21 respectively which loosely receive the ends 22 and 23 of the guides. As clearly shown in Fig. 3, the recess is slightly larger than the associated end/of the guide so that the guide may be adjusted relative to the seat on the bracket. However, if `one of the bolts should break, the outer wall of the recess would constitute an abutment there-by limiting the outward or radial movement of the end of the associated guide.
The construction described above is adapted for embodiment in new locomotives. If it is desired'to apply the invention to engines already built, then a structure such as shown in Figs. 4 and 5 may be employed.`
As shown in these figures a type of rear cylinder head 9 is shown which has the projecting brackets 10 for supporting the front ends of the cross head guides 15. For this purpose the bracket 10` on'- its outer side is lformed with a seat 13 against'which the front end of the guide is adapted to be held by means such as the bolt 18', shims 16 beinginterposed so that the guide may be adjusted to take up for wear. In this form of the invention it will be observed that the end 24 ofjthe guide is lat the left of the rear face 25 of the flange of the cylinder head. Consequently if the bolt 18" should break the guide 15 would drop down and perhaps catch in some object and cau'se serious damage., According to the present invention, however, an abutment is secured to the cylinder head to prevent the guide from falling down if the bolt should break. As shown a curved or segmental bar 26 is secured by means of the cylinder head bolts 27 to the flange of the cylinder head, and thisl barl directly under the end 24 of the guide is formed with a lug or projection 28, the upper surface of this lug being slightly spaced from the lower side of the gulde so that the guide may be adjusted with respect to its seat 13 on the bracket 10. It will be seen that a bar 26 may be readily and easily secured to present locomotives merely by withdrawing say four cylinder head bolts and. substituting bolts a little longer sothat they will pass through the bar 26 in addition to the flange on the cylinder head. Thus if the bolt 18' should break. or, for any ssv other reason, the front end of the guide 'i should become loose, the lug 28 would form an abutment, thus supporting the front end of the guide and limiting the outward or radial movement thereof. form of the invention has been described in connection with one cross head guide only, it is to be understood that a bar similar to the bar 26 would be arranged above the end of the upper cross head guide in a similar manner.
Although the invention has been described in detail, it is to be understood that changes may be made in the structure disclosed Within the scope of the appended claims.
Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
l. In a steam locomotive having a cylinder head and cross-head guides, brackets on the cylinder head extending in an axial direction therefrom, each having a seat on its Although this outer side parallel to the guides for the front ends thereof, and bolts for securing said ends to said seats, each bracket formed with a recess loosely receiving the end of the associated guide whereby the guides will be supported by the Walls forming said recesses in case the other supporting means should fail.
2. In a steam locomotive having a cylinder head and cross-head guides, brackets on the cylinder head extending in an axial direction therefrom, each having a seat on its outer side parallel to the guides for the front ends thereof, bolts for securing said ends to said seats, and an abutment located radially outside the end of each guide to hold said front ends from any substantial movement in case the bolts should fail.
In testimony whereof I affix my signature.
HARRY A. HOKE.
