REPAIR-CLAMP.
Specification of Letters Patent.
Patented Apr. 12, 1921.
Application filed March 8, 1920. Serial No. 364,113.
To all whom it may concern.
it known that l, l ILLIAM ANDREW Bonner An ons, subject of the King of Great Britain resident oi. the city of" "Winnipeg, in the Province of li lanitcba Canada, have invented certain new and useful Improvements in Repair-Clamps, of which the following is the specification.
The invention relates to imPIOVGlIlBiltS in repair clamps and particularly to a repair clamp for use in repairing broken rails and the principal object of the invention is to provide a clamp which can be readily placed in position in respect to the rail and which can. he quickly tightened up and set to hold a pair of angle irons or fish plates in place on opposite sides of the rail at the break thereby effecting quickly a temporary repair which can be relied upon to sately carry the traffic until a final repair can be made.
A further object to construct the clamp in a simple, durable and inexpensive manner and so that it can be quickly adjusted and set and as easily removed.
With the above more important objects in view, which will. become apparent as t 1e description proceeds, the invention consists essentially in the arrangement and construc tion of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Figure 1 is a side view of a pair oi": my clamps as they appear in use.
- Fig. 2 is an'enlarged detailed sectional view at 2-2 Fig. 1.
Fig. 3 is a horizontal sectional view at 3-3 Fig. 2.
Fig. 1 is a vertical sectional-yiew at l4:' Fig. 2.
In the drawing like characters of reference indicate corresponding parts in the several figures.
1 represents a track rail spiked as is customary to the cross ties 2 and having a break or fracture 3 therein such having occurred in the ordinary course of trafiic and requiring repair.
My invention provides a clamp for quickly repairing such breaks in the rails and in actual practice two clamps are used together with the customary angle irons as at present employed for connecting the adjacent ends of rails. Each clamp is constructed in detail as now described.
41 is a, base plate or shank having one end The other end of the shank is supplied with an elongated substantially rectangular slot 8. On the latter end. of the shank I mount slidably the base 9 of an adjustable jaw 10 which has the upper part thereof turned inwardly as shown at 11 and then upwardly to provide a gripping end 12 disposed in a vertical plane and opposing the gripping end 6. The end 12 is also supplied with an inwardly extending stud 13 located directly opposing the stud 7.
14 is a am screw having a squared head 15 and screw threaded through the end 12 or the jaw 10. 16 is an adjustable bolt fitted at the lower end with a squared head 17 and provided with a nut 18.
Here I wish it to be observed that the base of the adjustable jaw is connected slidably to the shank by means of two inturned L-shaped flanges 9 and 9" and that the head 0]": the bolt 16 is received between the flanges which prevent it turning while the body of the bolt passes up through the slot 8 and through a receiving opening 19 provided in the base of said jaw. The nut 18 is applied on the upper end of the bolt. Obviously when the nut is loose one can shift the adjustable jaw in and out on the shank and he can, by tightening up the nut, secure the said aw firmly in any adjusted position as the head 01 the bolt underlies the shank at the edges of the slot and is prevented from rotating by engagement with the flanges 9 and 9".
When a broken rail is to be repaired two of these clamps are used together with a pair of angle bars 20 and 21, the angle bars of ordinary construction, being designed to fit against the opposite sides of the rail as best shown in Fig. 2 and they are provided adjoining their ends with pairs of cross openings 22 and 23 which are adapted to receive the customary fastening bolts passed through the web of the rail.
In making a temporary repair, these angle bars are placed on. opposite sides of the rail at the break, taking the position as best shown in Fig. 1 it being here understood that the bars are positioned directly opposed. The sectionman, after having placed the angle plates, puts one of my clamps at opposite sides of the break and tightens them up to hold the angle bars tightly in position against the web of the broken rail.
As the manipulation of each clamp is the same the description of the manner in which one is applied will suflice.
To apply the clamp one removes the adj ustable jaw from the shank by knocking out the bolt 16. He then puts the shank and fixed jaw in place as shown in Fig.2 with the shank under the base of the rail'and After the two jaws have been initially drawn up as tightly as possible to jam-the angle bars agalnst the web ofthe rail the nut 18 is tightened up to hold fast the adjustable jaw. The final tightening up is then made by turningthe jam screw 1 1 which takes up any looseness there might be. 7
From the above it will be apparent that by'using these clamps a reliable temporary repair can be very quickly made and that afterward a final repair can be carried out by drilling the web of the rail and fastening the angle bars to the rail by bolting in the ordinary manner.
What 1 claim as my invention is 1. The combination with the broken ends of a rail and angle bars disposed at opposite sides of the rail at the break, of a repair clamp presenting a shank passing beneath the rail, a stationary jaw extending from the shank and engaging with one of the angle bars, aremovable adjustable jaw engageable with the other of the angle bars; an adjusting screw carried by the adjustable jaw and alining studs extending from the jaws.
2. repair clamp comprising a shank provided at one end with an integral aw, a second aw slidabiy mounted on the shank and provided with inturned flanges embracing the sides of the shank, an adjustable bolt passing through said shank having the head thereof engaged between said flanges and thereby held against rotation, and a V nut engaged withsaid bolt to lock the bolt and sliding shank. g V Signed at Winnipeg this 17th December,1919.
